These are the notes from the [https://www.noisebridge.net/wiki/Category:Meeting_Notes The XXXth Meeting of Noisebridge]. This is also a BOARD meeting

Date: JUNE 25 2019

Note-takers:
Lemons
Tyler
Ryan
<Lady Red copyedited notes in before posting>

Moderators:
Lady Red

== Board Meeting Agenda: ==

1. Elect officers
It seems like we have general agreement that Tyler should be the new Treasurer, so this could be a good time to make that official.

2. Review your bylaws, discuss procedure and substance for possible amendments, at least for amendment procedure.
Our bylaws currently have no amendment procedure, which means the board can de facto amend them by majority vote. We ought to discuss if we are comfortable with that or if we want to make it harder to change our bylaws. Krebs thought this seemed important.
Also, I’d like to discuss if we see value in enshrining consensus into our bylaws somehow. Not a simple topic, this could be just the start of the conversation
3. Receive a financial report from the Treasurer
4. Authorize a budget
5. Review and make the required annual report to the membership 2.
6. Receive a report from Perkins Coie (Alice the Lawyer) about what they have found regarding our situation with the zoning department and our options for a new home for Noisebridge. We’ll publish as much of that as seems prudent

Lady Red- we need a Quorum of board members so 5 Members as we have 9 members of the board
Lady Red- We need to go through our bylaws, we need an amendment procedure
Lady Red- I think we may want to make it more restrictive than 50% vote to avoid Noisebridge being taken over by a rouge board
Lady Red- this is the first board meeting in person
Lady Red- review the annual report
Tyler- we do not have a budget, but we have an annual report

Items 3 (), 4 (), and 5 () require quorum
Nicole (@garrdn) is joining

We have reached a quorum!

== Report from Perkins Coie ==

Alice- legal council for past 6 weeks, we are trying to raise funds more normally, currently limited as a pro bono, but learned about having some other issues, Perkins attorney has been helping out as pro bono land use, real estate, and zoning to looking our issues, Rachael will

Laura: printed copies of issues list, circulating to all present.
Laura: will go through the list with us about our issues.
Laura: NB is looking to enter a lease for 668 Guerrero.

Laura: addressing the topic of "development impact fees" for current space.

Laura: we have still not seen the original copy of the proposal.

Laura: construction of notice of violation

Laura: proper permits had not been filed,

Jared,- someone complained that we are a public facility which we are not zoned for. Then we did not get zoned for that, we then talked to the city and convinced them we are a community space which is a certified provisional use of our space.

NB could be qualified as a community facility.

$92,000 was the cost, "development impact fees" ( one specific to the Mission, one for public transportation )

Matt: why would the fee impact us if we move?

Ruth: if we undo the construction does that undo the fee?

Laura: I did not think of that

Shutt: from garment shop to community facility ... needed to legalize the use of space.
wasn't a construction fee, it was a use fee. Would that change of use still happen?

Laura: fees were assessed because of PDR -- typically when commercial -- certificate of occupancy.
"use change here" -- assess fees.

Step 1: fees apply to new, non-residential development. Development = definition: construction.
Step 2: fees are assessed by the change of use. Additional construction done here, would not have the same fees again.

"pulling construction permits wouldn't matter because the change of use still happened"

ANOTHER LAW FIRM: SMALL LAND USE (Ruben, Junius, and Rose), was pro bono work,

http://www.reubenlaw.com/

Jared- was it a reduced fee or full pro bono work,

Laura- they might have a more factual background

Jared - we reached out to ReubenLaw - so that we would have an application in the system before the "Directors meeting"

code enforcement not moving

I have the letter ... describes impact fees ... I (Jared) can forward to you right now

Laura- we are not sure if we are able to reach out to the other law firm,

BOARD or OFFICER COULD GRANT AUTHORITY for PERKINS CONTACTING RubenLaw(reach out to the other law firm that helped with permit strategy)

Lady Red- I, as president, give permission for Perkins to reach out to the other law firm, do any Board members oppose? (none do) We will move this to later, as we discuss new space.

== NEW SPACE ==

Laura- *passes out legal analysis* Analysis for 668 Guerrero, we reviewed lease from the landlord

Laura- Zoning of property is RH3 - the quietest residential zoning

Laura- NB is "community use" facility - conditional use permit is required.
Current non-conforming commercial use -- as the law applies in 2019 a commercial facility is not allowed.
however, at one point, it was. Specifics of planning code that apply to RH3 district.

"Special limited commercial and industrial use"

NB has to qualify as "limited commercial and industrial use"
has to be more than 1/4 mile from some special districts - the space is not more than 1/4 mile than the special district - it is by Valencia District

NB does not qualify (we do not sell anything that fits the designation, we do not sell any convenient community goods (bodega, grocery, corner store))

Land use and tax purposes
* if you are a renter as a 501c3 do not get an exemption as an owner
* different status as renter vs owner

Can we piggyback on nonconforming use we are within a fourth of a mile of a Commercial district (Valencia Street)

Question - what is the most natural zoning category for Noisebridge?
Legal advises: NB is most naturally a "community facility"

LadyRed: what is the classification most likely for NB to be allowed to move into other spaces?
Legal: We didn't fully analyze that, it depends on where you are looking.

Option 1: extend the existing lease (negative impact: 92k impact fees. Might have to pay anyway)
Option 2: extend the existing lease and look for other new locations
Option 3: enter into 668 Guerero lease - Legal does not advise this

Laura, and Alice- We do not recommend going into the Guerrero lease at this time, it is extremely landlord friendly

Lease from the landlord is copy-paste from the internet. We have been planning to rewrite it.

NB not in a position to sign the lease as it was given to us

Current lease for 668 Guerrero: permits, zoning, etc.

Talk to the landlord about lease terms, allow abatement of rent while NB is pursuing proper permit ...

as liability stands in the current lease: NB is responsible for paying rent while trying to obtain permits.
CUP takes estimate 6 months.

Ruth-- if we expand to the space below would we need to do anything?

Laura- I did not have time to look into that

== DECISIONS THAT NEED TO BE MADE ==

Laura: as a business matter -- *how does NB feel about paying 2 rents at once*? This informs our negotiation strategy

Laura: how does NB feel about paying rent while permits are pending?

Nicole (remote): Is Noisebridge's best route to just find another PDR or other appropriately zoned space?

Laura: YES -- something to look into - community facility use.

Some zones are helpful with Permitted by right spaces can avoid a number of these issues

Jarrod- "Find my zoning" on the SF planning website
https://sfplanning.org/zoning

Matt- We have an estimated cost of 50 grand for renovations, and 50K in options. To pay for those, We need to raise revenue by 200000 over the next four years We could lower renovations and options cost, but that still leaves us with 150K+ in extra rent to make up in revenue over the full span of the lease

Andy - How does the city want to see us? What is the most natural zoning and land use for Noisebridge?

Laura: "Community Facility" makes sense ... different workshop areas may lend to PDR

It's possible to apply for a Zoning letter of determination (it is public and it can hold a lot of weight) which permanently sets your zoning. This takes about a month and is permanent so you have to be careful.

Q: Is it possible to get multiple zoning classifications for determination?

A: would have to go through zoning determination letters.
Off the top of my head, dual use is not common. Primary use.... accessory uses maybe?
One use will be classified as a primary use, other uses are accessory.

Jarrod- On the third story of a space, many PDR spaces are not allowed

== Board Meeting Start ==

5 minute break

Board meeting back in session

Attendance is 6 of 10 board members:
Lady Red
Ruth Grace
James (@jslack)
Steve
John Shutt
Nicole (@gaardn)

Board members not in attendance:
J
Lee Azzarello
Naomi Most
Victoria Fierce

Note that J has moved away.

== Agenda Item 1 - Tyler for Treasurer, confirm existing officers==
----

Likely no formal process has taken place for naming the current Treasurer. Likely that Nicole is currently the legal Treasurer. ...Has been updated previously on the wiki, for what that is worth.

Treasurer history (most to least recent):
Nicole
John Shutt
Patrick
...
Lost to history

Can we add a second CFO or assistant to the Treasurer? Tyler would be okay with it; could be done without a title. Lady Red feels a title could be helpful. Ryan feels having others able to sign in place of the treasurer is a good thing. Could already be possible with other board members. Nicole is cool with continuing to assist.

Raised Tyler to the position of treasurer:
unanimous approval by the board.
note: Making Tyler a board member needs a board election from membership.

someone: it would be best for board members to be people who have interacted w Noisebridge in the last year. prevent people from owning the domains etc where people at current noisebridge don't know who they are

we can do a board election later this year in an attempt to add Tyler and remove J if he's not interested in being part of the board anymore
not being able to contact someone means they're not interested in being on the board anymore

Ryan: can we check once a quarter to get board members to reaffirm?
Ruth: once per annual election is enough
Lady Red: according to by-laws: if you miss 3 board meetings you're automatically out
Tyler: at least one person on the board should have all the contact for all the other people on the board
Lady Red: I looked at a list of board members document and it didn't have Lee on it, that's why I didn't message him about this

votes for other positions
president (Lady Red) - Unanimous
secretary (Victoria) - Not Unanimous
treasurer (Tyler) - Unanimous

when did the president change happen? Ruth ran the election among board members for president for fundraising (we needed a president for grants when Patrick stepped down)

Everyone who's cool with Lady Red being president

J: It's weird when something changes like the president and I didn't know about it.. kinda sketch
(others explain that it happened in summer 2018)

for a long time, the identity of the president was secret

Steve: is Victoria still involved?
Ruth: ran gala and burned out
Steve: I feel that's a "yes"
Nicole: not comfortable with Victoria being a secretary because she sabotaged some important things for noisebridge
James: not sure what you are referring to
Ruth: are you sure she did it on purpose?
Steve: my feeling is that Nicole should not have to defend her denial, like with membership
James: this isn't membership, we're trying to have a transparent meeting right now where we're taking notes on what we're talking about. nothing to do with membership.
Lady Red: according to bylaws, officers shall be chosen annually by the board
John: potentially we should discuss the Victoria situation offline instead of in this meeting
Lady Red: So at this point, we're not going to unanimously select Victoria, and we're not going to unanimously select someone else. if Nicole is not going to verify her -- I don't know what the voting rules are, let's just not do that one then. maybe we'll get a new secretary or discuss it for a while

----

== Next Agenda Item - financial report from the new Treasurer!==

Tyler: this does not include a budget. a budget would rely on a decision of whether or not we would move. budget is materially different depending on lease and construction obligations (materially means substantially). This financial report has already been released to the membership.

Tyler: brief overview of noisebridge financials!
Here we're looking at 2018 summary of income. we made 259K last year. that's skewed a little higher b/c we had 100K investment from Handshake, which is a crypto something, which was awesome, secured by Mitch. That brings us down to -- total operating expenses $60,000 rent (last year was $4250 for rent, at our last lease renewal in August we went up to $6500 which is the current rate we're paying for rent here), so that's why it averages over the last 12 months as 60K. insurance
Krebs not significant in 2018 but was significant in 2019. Uncategorized is me summing together a couple of other line items, something I'm continuing to work through and going through bank statements to see what these fees were. We netted 108K. If we had not gotten the handshake donation we would have netted 8K

Year to date through may
may for 2019 and 2018
I actually need to re-release this because there's an error here, the same number as the previous chart, copy pasted wrong numbers.
Up until line that says Other under total revenue this chart is accurate.
Utilities down a little. But 18K spent on Krebs. Comes out to 35K total expenditures to Krebs. This was the big thing driving our decrease in cash year over year. In cash, most of the increase is handshake and most of the decrease is Krebs. Even with removing Krebs our change YTD would have been 2K in cash balance, which means we're still getting fewer donations (it was 14K last year)

Lady Red: thoughts as to why donations went down?
Tyler: cash not counted for a while. at least through the end of March, there were no cash collections, and we know we had at least one consistently active money thief. So we're losing money. That probably equates to about 2K per month, is what we had been historically collecting in cash. So that's potentially a loss of 6K to theft. Beyond that, I can't speak for some of the changes in our average donations. I know somethings are -- some things are weird bc we get small one time donations that cover a lot. for instance, when I redo this chart in a months time and we have numbers through the end of June, this will include someone had donated 1 bitcoin which has a market value of 12K right now. So that's the equivalent of having an extra months worth of donations in there. So it comes and it goes, comparing periods of this might be inaccurate if we had one person chip in 10K.. Where our money is coming from is something I'm still working on. People paying monthly or people rotating through making small 1 time donations? hard to piece out what the real answer is.

Lady Red: not enough info to find trends other than people were stealing stuff?

Tyler: yes. but also we weren't doing classes as much. CHM stopped. The general opinion is that a lot of people previously very involved were no longer involved. there's the idea that those people were teaching classes and were driving events in the space that would have generated more money last year than this year.

running end of month cash balances
biggest change from July to August 2018 is from making 2K plus 100K donation
in some months -- for a while we were relatively even, either making or losing 2K. The last -- mostly due to our expenditures towards Krebs -- the last April may it was down 5,6K. We've went down a lot this year. As of now, we are at 166K

Krebs had 2K retainer, but we were billed for extra hours, and we used extra hours.

Tyler will realign the bottom row of this chart

cash
you can tell where 100K came in
a trend worth addressing: before handshake we were at a break-even point. Once we got to 200K it's been a slow trend down. I think entirely due to Krebs. Krebs plus theft.

Steve: is x-axis the same as the one on next slide?
Tyler: yes, Jan through may

monthly revenue

Ruth: end of year fire drill fundraising campaign didn't make a dent
Lady Red: most significant thing on any of these charts is handshake donation, and none of us did anything to get that.
Tyler: shows these donations are possible but potentially we haven't been reaching out to people for them
Ryan: mitch and other nose bridges extensively talk internationally to other spaces, get donations from groups internationally. since we don't have much or Scotty anymore we don't have nearly the number of Chinese or Asian corporations who think about donating or Europeans. I don't remember how we got 20K during Jan 2018 but I feel like that's right about the time ... trying to remember what we did in December 2017, but I think we did something with a number of groups, need to look through our things.

Tyler: the 100K is in August but it didn't get added to this chart. will add note and re-release

John: I think it's possible to break out donations that look weird from donations that look recurring so you can get a feel of this comes from PayPal, stripe, cash, regular recurring donations that look pretty normal vs somebody gives us 1000. and see whether the regular recurring donations are covering the regular expenses. and then raise the alarm if it looks like regular recurring donations are not covering regular expenses.

Tyler: I have that analysis, not included in this annual report here. can include a slide here. 4 donation channels: stripe, benevity, PayPal, patreon, cash. One of the other issues is, a lot of times when ppl make these large donations, they go through Stripe or PayPal, that's where it becomes a little harder to sort out. what is considered large? go through each donation for each one of those channels for each month.

Lady Red: if you did have that kind of analysis of monthly recurring stuff. if we're asking people to sign up for monthly recurring and we're like, we have this level, we want this level, we can include that in the ask.

Tyler: The goal I want to set, a goal that I think we can hit, is 15K avg monthly donations
we've had numbers above that before but our avg is 12K
our avg during this year is like 9. so I think it'd be good to push like that for our average
break it into 2 different goals: what should our avg monthly donations be, and find a way to get better info on our monthly recurring donations. one suggestion that Ryan and I had was pushing more people towards patreon.

patreon good at tracking not individual people but tier levels. you get different rankings based on what group you're in (starving hacker, platinum, etc). while you don't have the granularity down to -- not the public granularity of Ryan paid this much money -- is visibility of nb has 50 donators (patrons) who are supplying $200 per month. that's helpful for us to see what's a good recurring number. helpful to show to the outside world saying hey look at these people all coming to support nb, reasons you should. use that as advertising

Ruth: are patreon fees significantly higher than stripe?
Tyler: higher, not significantly higher

bring in meetup data too to track if there is any correlation between big donations and meetups as far as cash goes

== Discussion on Raising revenue ==

Tyler: thanks for bringing that up, want to point out different revenue drivers for nb, classes are a great idea for bringing more money to nb. props to Robert for restarting CHM. got pretty good crowds since he's been doing it. also Jarred with python class. both of them do a really great thing.
at the end of the class, they round people together and mention that "hey this is all bc donations to noisebridge, and we need your help to continue to support and donate to nb". people typically donate right after that.
bad practice: when Nate did network hacking class, brought 35 people to nb and they were all sitting right here, and when it was done, everyone stood up and walked out the door. It was a really good class to bring ppl to nb, but if you don't mention to people or remind ppl that we rely on donations, people will be like free class, see ya, head out the door

Lady Red: one of the best ways people can help nb is to build these recurring classes. Recurring classes that have high attendance. If we had another circuit hacking Monday equivalent sized class on Wednesday and Friday we might have 15K per month.

Freddy: working on a SQL database recurring class for the notes

also interested in teaching Linux class

Tyler: spitballing classes totally encouraged. come up w better format for holding classes
lot of people come in and ask that question, can I have an event here? usually, we say do-ocracy, do whatever you want.
Lady Red: more support
Tyler: this is more support, how you get on meetup, general class guidelines, this is what we expect on classes, cant be offensive, should mention to ppl that this is a community space that requires donations to maintain
Bernice: announce and events. I have been peeved that people have been shunting things to me. I thought there was a group. but people think Bernice is in charge of events.
Tyler: there is a general opinion that Bernice is in charge. but she's not.
Ryan: Bernice gave me privileged access
Ruth: there are multiple people, myself, Lady Red
Lady Red: this is one of the most important topics for nb to talk about, but after
Tyler: one more finance related item -- fundraising meetings. those were happening and stopped happening. a lot of burnout in the fundraising process.
saw that Ruth posted a nice fundraising onboarding guideline. might want to get back into having fundraising meetings that occur at nb and we announce them and get a bunch of people involved. a lot of people ask to be involved, but we haven't had a lot of info or ongoing tracking or notes. fundraising notes should be equivalent to meeting notes so that if people want to get involved, they can see what's happening.
Ruth: We have been posting fundraising notes on slack and, more recently, discuss
Ryan: don't need to go through fundraising meeting for tools donations, in-kind donations can go through small c consensus. a lot of groups want to donate materials but we have no room. money is what is critical right now. if people can focus on helping the fundraising group for getting grants and donations of cash, bitcoin

Nicole: speaking of recurring classes: I need help to set up a dedicated vinyl cutter computer in the space so I can teach classes to make custom t-shirts, bags, etc.
the PC needs to be Windows, sadly, but I do have a Windows 10 license if needed.

Lady Red: moving on with board meeting, really appreciate that report.
being able to see the financial situation is really important, as soon as we saw it we started spitballing ideas for how to fix it.
might be the most useful thing we've done today.

== Last Agenda Item: Review Bylaws - discussion on restricting board power ==

Lady Red: I want to get the board's feelings on our bylaws if we would like to make any changes.
Josef Krebs said: notification requirements not there for certain meetings ... not having any amendment procedure is a glaring hole.

Tyler: move to have this raised to a consensus item, bc I think that is something that will benefit from long-form communication on something like discuss going back and forth. for instance "propose to edit 3 items within our board agreement, these are the proposals and why"
Lady Red: I think it'd be fine to do consensus, the board can say "consensus has spoken, and we are the board, we follow consensus". but at this point, it's premature to say that I have a proposal. I just want to talk about it. We can't make a consensus item without knowing what it will be.

(Lady Red shows email sent by Krebs, offers to send it to anyone interested)
James: post it to discuss
Lady Red: yes.
Lady Red - The noisebridge weekly general meetings are the 'membership meetings' in the bylaws.
Ruth: does certain number of members have to be at each one?
Lady Red: doesn't say that
Tyler: from bylaws perspective, we don't specify the difference between big m and little m members. members are just member of community or members of noisebridge.
Lady Red: I think actually that people who aren't capital m Members don't appear in the bylaws. they're not referenced in the bylaws in any way.
Ruth: doesn't think members without capital m should be referenced by bylaws
Lady Red: So, the bylaws describe a board governance procedure that we're really rusty at. It's been like pulling teeth to do this one meeting. In the longer haul, would it make sense to enshrine the consensus process somehow in our bylaws? It probably wouldn't be that hard - sample language is "Any action that the board could take can also be taken by a consensus item passed at a member meeting"

we could say consensus can do anything board can do.

James: but then people would ask for everything board can do to require consensus - to require consensus before the board does anything
Tyler: something about veto power
James: as a board what would we want to accomplish?
Tyler: risk of doing it consensus-based that, for instance, Lady Red president bc we need someone's name on the grant applications and people will not consent to that because "why do we need a president", and then we never can apply for grants
Lady Red: Right, the consensus default is always nothing happens, even if that's the worst outcome
Tyler: requiring consensus for board actions would make it prohibitive to business

Steve: review real quick what motivation was for putting this in bylaws?
Lady Red: in general while, I was talking to Krebs we talked about how weird the bylaws are and how they specify a board governance that we basically don't do. we basically govern everything by consensus. If we were to write our bylaws with the consensus process it could be something that other orgs could follow and we'd be setting an example. That was an idea Krebs had and I wanted to gauge support
Steve: that's something I don't see as that important
Lady Red: different note, another thing he said was a glaring hole is that currently there's no amendment procedure to the bylaws, which means the board has the power by default
Steve: who has the power to change bylaws?
Lady Red: the board has that power, by majority vote
Tyler: that is a problem bc why?
Ryan: for a long time board was never to do substantial changes to nb which includes bylaws of nb without consensus, that's the current issue. people worried about too much power being in one court or the other

Tyler: real issue: the fact that the board can change bylaws at any point in time by majority vote is not very secure for an organization and as a result people may be unwilling to provide us with money bc the issue is - right now, we don't have anything on our bylaws about how to handle donations, esp if they were earmarked (ex. 100K for continued economic empowerment in the mission) we don't have a way of saying how we will handle that money. that can go into our bank account and we can buy 2 dozen laser cutters. that's why people donating money will look at bylaws and say hold on you have no control over the money once we give it to you, so we can't donate it to a cause like that because you can just spend it on whatever you want. If we were to enact controls to protect the donation, we'd still be able to change it back in a single meeting

Lady Red: yeah it's very unstable. the most relevant point to this is the Reboot. Noisebridge was going to utter shit, all sorts of people living here. there was a big feeling that everyone at nb was either going to die or need to have some total rebirth. ended up being that the board go together and decided that they needed to take control, and get rid of consensus, consensus govt was main problem at nb bc nothing could get done. somehow board voted to get rid of consensus. a bit fuzzy on how this worked bc consensus is not in bylaws. the board attempted to actually do something. some other process that I don't understand, the board got kicked out. Someone who was there, help me out?

James: The people on the board came together to make decisions on behalf of the space and remove consensus. Basically all came to a meeting like now, and it was announced that that had happened, and it wasn't the board that made any real changes to the space, it was them declaring that consensus was no longer a part of Noisebridge that caused change at nb. totally palpable backlash of every person in the room. almost like a movie where a superhero hits the guy and knocks out of the stratosphere to another planet. everyone was like "absolutely never going to happen, get the fuck out". a lot of hurt feelings. a lot of people on that board left nb and never came back. they thought they were doing a good thing. then all these ppl came together to work on the space bc they were going to do it as a doocracy thing

Lady Red: everybody agreed it needed to be fixed but in the way, it happened board go thrown out, and then it got fixed
Steve: strive only to do what is necessary and preferably less
Lady Red: board attempting to do that is just as possible now as then. we haven't restricted the board in any way.
Steve: general idea - I think we should meet again soon and talk about how we want to fix these bylaws. We ought to take the advice of these people(Krebs). take their advice. hash it out, think about it, and then take the proposed bylaws change and make it a consensus proposal. Sure we have the power to do it but we're going to present it to members. "this is an important change, we have legal power here, but we dont want to do anything that's going to piss yall off. so we're choosing to do the morally right thing which is to put this out for consensus proposal". maybe it'll be bureaucratic but at least we will have done due diligence and the right thing

Tyler: raise on discuss as a proposal with "these are a few of the key points that we would like to change about bylaws" and phrase it in way of the main goal here is to make ourselves more -- limit the power of the board, to make ourselves more attractive, to be able to accept fundraising. have financial controls such that if someone were to donate large money we can't just wire it out the door the next day.
Lady Red: I want to start the ball rolling on this. it's one of those things that's really hard to know what the right thing is, not necessarily one right decision.
Tyler: we could reform as a country club
Steve: we have enough white males
Tyler: they are all member-owned and run by a board, all 501c3
Ryan: hilarious and interesting
Tyler: if we set up a putt-putt course just over there we would be fully qualified
Lady Red: I hereby close this board meeting

== Final Annoucements ==

Bernice announcement: I wrote that there's going to be whiteboarding and also a workshop on Sunday and we're going to go through it, found someone to help me, will put all relevant info on discuss, etc.
Sunday at 1. more structured than Wednesday freeform

The general meeting is over, next week a lot of stuff will be discussed in detail. Please tune in!!!!

Safe Space:

*Financial Report*

Funds in bank: $173,255.69!!!!!!!!!!!!

Noisetor (See the bulletpoints at the bottom of http://noisetor.net/finances/#summary): dead (check with elimisteve)

Tyler wants finances to be open to everyone! To acomplish this he will be posting up to date info on a weekly basis! Below are some examples!

- Weekly cash collections
- https://docs.google.com/spreadsheets/d/19S9YNHdM2S7gpzPm3l5G8mbBo52TtwrORqCvGs5eP9A/edit#gid=0
- Reimbursements
- https://docs.google.com/spreadsheets/d/15HsJqcqxwcBZn6UgK7xR6YD3C6UFLBwOcBmbB8Xy6yI/edit#gid=0
*Tyler tries to hijack projector screen*
*promises to give it back*
*matt says you keep the screen! he needs a break*
- tyler started collecting cash

- shows the audience a spreadsheet

- talks about how he started collecting cash, shows us more data

- matt says he can destroy the old cash box as a joke lol

- the audience is looking at the broken cash box

- A lock may have been able to jiggle open

- "Neet to get Reimbursed? Let Tyler know!" tyler.maran@gmail.com / @themanmaran on slack & discuss

- Use a beefy ass lock / "beefy" ass lock

- We collect around 40-70 dollars a day in cash

- We reimburse people fro contributing to the space

- two funds. one pays 100%, one pays 50%. 100% for fixing stuff in the space?

- For example someone was reimbursed for saw stop

- Alice raises the concept that maybe its a good idea to reimburse 100%

- If you want to buy something new for the space then reimbursement may be 50-50

- info on discretionary fund is in consensus items

-

- Financials: donations are down, becuase of the cash theft that was happening

- We could put our money into a higher interest accoutn and get an extra 4k per year

- We are above the amount that we were supposed to spend with Scanduzzi Krebs and they have not been asked to stop.

- Scanduzzi krebs is a grant consultant

- The fundraising team has not discussed whether to keep scanduzzi krebs

- We should stop paying Scanduzzi Krebs because the money limit set by the prior consensus items has run out

- Alice has not seen the people in the fundraising commitee because they have not been in fundraising meetings for the past few weeks

- Brief history of fundraising group: Hired Scanduzzi to do fundraising becuase this guy thought that there was no better investment than fundraising, there was a call but it was very hard to get people involved. The original fundraising team has been at each others throats for a while.

- Alice originally came to solve the burnout problem.

- R has a direct response: What happened to the Tuesday meetings

- WE PAID SCANDUZZI KREBS $1000 to ATTEND THE GALA lol!

- What is Scanduzzi doing for us? Not Scanduzzi's fault that we've spent a lot of money on them. You have to understand what you are spending money on. We werent' sure what we wanted. Scanduzzi did everything they could. They have presented us with different avenues to try. They are putting grants in front of us. There are a lot of other things that go into grants. They get us meetings with local politicians. They put packages together so that we can try it out.

*Consensus*

- We are outside of the proposed consensus limits for hiring Krebs (consulting). The consensus was to cover $29,000 of total spend.
- Payments to Scanduzzi Krebs will be paused until there is another consensus item authorizing new funds for them.
Proposal for Noisebridge to move to 668 Geurerro street

- Rent is about a 50% increase

- Concrete floors

- No neighbors

- Option to purchase for 4mm

- 2.5 blocks from current NB location

- Access to BART

- Geurrero is much less sketchy than Mission

- Early move in clause gives us 2 months of free rent

- 10k per month for the first year, 1k step ups per year up to 13k.

- I am raising geurroro for consensus because it is good for NB

- New location gives NB a blank slate to reivnet

- Option to purchase the building gives a fundraising goal

-

*Discussion of Consensus Item*

- Cons: the cost

- But our rent here may be raised again

- There is a 100k fine which may be imposed on us or maybe the landlord at the current location, Details available here http://dbiweb.sfgov.org/dbipts/default.aspx?page=Permit&PermitNumber=201712217127&Stepin=1 (click "Show Site Permit Details") and additional details regarding hte building are available here: http://propertymap.sfplanning.org/ (enter address)

- Ruth started a message with Trent and some other people about reaching out with current landlord to renegotiate lease. But there have been no discussions yet

- Jarrod is trying to schedule a 3-4 hour tour of the building and do a timing and cost estimate on what needs to be done to it

- R: Trent is a Member who has communicated with the landlord before

- R: we recently talked to the property manager who says that we are back in an ok standing with the landlord

- Alice has teed up a real estate partner at perkins

- Calling the city is something anyone can do. Communications with the city have been really stretched out over months.

- R: One of the big expenses of staying at current location is potential fees and fines

- The 92k fee is related to the fact that we are in a space that is not zoned correctly for Noisebridge. The $92,000 fee is for the permit for zoning change, which we would cancel if we moved. So moving would make this fee go away.

- Elevators have also caused additional legal risk and have unresolved costs. yo

- Having the option to buy a building is awesome

- A new space gives people a blank slate to create their own stuff. Everyone could gain skills.

- Our biggest issue is defining what the fuck we are as relates to zoning

- (Out of order) We need the views of the architect and electricians who are going to go to spend 3-4 hours to tour the space with Tyler.

- Mark: it's june, we need to pass something now or never.

THIS CONSENSUS ITEM WILL GO THROUGH NEXT TUESDAY and if it is not blocked next week it will pass. Plea for additional Members attend.

- 501(c)(3) status. Deductions are available. Individuals can contribute and deduct amounts contributed. In certain circumstances, appreciated property may be eligible for deduction at fair market value without recognition of built in gain.

- June 25 meeting - board meeting - how will non-members attend or witness the board meeting?

*Proposals for next week *

Consensus item next week for 668 Guerrero

*Discussion*

|-
| Nicolas H.
|
| Nick has been asked repeatedly to not drink in the space, and he continues to do so. His repeated lying about it, disregard for rules such like sleeping at the space, and causing hindrance to others makes him unwelcome until such a time that he can prove to the community he is able to function within it's bounds.

|-
| Alexander Lee
| [[File:Alexander_lee.jpg|200px|thumb|left|Alexander Lee]]

| [[File:Andrew86_1.jpeg|200px|thumb|left|Andrew]] [[File:Andrew86_2.jpeg|200px|thumb|left|Andrew]]
| Andrew was behaving extremely erratically, with delusions and hallucinations about those around him. He accused one person of trying to reprogram him, made multiple racially charged comments towards others, would not leave people alone when asked, and often could not perceive their words when they were speaking to him because of his hallucinations about what they were saying to him. He also tore up the anti-harassment policy and was extremely difficult to remove from the space because of his inability to recognize what was being asked of him, and because of all the stuff he had accumulated around him physically.

|-

He now has a bit longer hair (though still short) and is a bit bigger than in these photos -- one factor that might help identify him at other spaces is that he has been coming in with his girlfriend (who Sudoroom has no issue with) who has blue hair. November-2017

|-
| Jason
| [[File:Jason.jpg|200px|thumb|left|Jason]]
| After being very helpful and friendly at Noisebridge for several months, others became very concerned and uncomfortable with his growing talk of conspiracies against him at Noisebridge, with hints of violence targeted at those he felt were part of the conspiracy. His erratic behavior and the above threats of violence resulted in Jason being asked to leave Noisebridge at the end of September, 2016.
|-
| Lance
| [[File:lance_combined.png|200px|thumb|left|Lance]]
| Lance was formally banned from Noisebridge in September 2016, although he has previously been asked repeatedly to leave and not come back. He refuses to leave the space peacefully and always requires significant effort to get him to to leave Noisebridge. He is a textbook tweaker, who while peaceful in his interactions with people, mutters threats under his breath.

*Note: He repeatedly tries to come back to the space, even when asked not to return (Once in April 2016, and twice in August/September 2016). He tried to enter again in October 2017. If asked to leave, he is not dangerous, although he is quite vocal.
|-
| Mark Janssen (Xer0Dynamite)
| [[File:Mark_janssen.jpg|200px|thumb|left|Mark Janssen]]

|-
|Diana
|[[File:Diana_ban_photo.jpg|200px|thumb|left|Diana in June-2016]]
|Diana was banned at Sudo Room in June-2016 for physical violence against a member. Since Diana was banned for safe space reasons, they are automatically also banned from Noisebridge. 
According to an email from Sudo Room: "This was an escalation of a dispute between two people who had an existing relationship and Diana lives very close to sudo room so you shouldn't worry overly about a problem at other hackerspaces." And from the Sudo Room "Asked to Leave" page, Diana "Additionally has been using the space as their living room (playing WoW all day) and caught sleeping at least twice."
|-
|David/Bunny
|[[File:David_Bunny2.jpg|200px|thumb|left|Bunny in March 2016]]

|-
|Adam
|[[File:Adam.jpg|200px|thumb|left|Adam in December 2015]]
|Asked to leave having been caught stealing from others in the space.

At several points misused the space in the creation of his "art", hiding large amounts of "art" around the space.

Was caught sleeping in the elevator overnight in late November 2015.

Was asked to take a break in late November 2015 after the sleeping incident and initially agreed to do so, but then returned repeatedly to the space claiming that nothing was wrong.

|Matt the tweaker
|[[File:mattthetweaker.jpg|200px|thumb|left|Matt the tweaker]]
|Matt carries a backpack full of shower rings twisted with tangle therapy tangles. He has converted his brain into a computer and is using it to solve the tangles with an algorithm. He is quiet and not aggressive, but very fixated on his tangles and can't form a completed thought, continuing on until you interrupt him.

Persistently tell Matt that "you have to leave now" and walk him out. He will go about 5 feet at a time but is not aggressive.

|Asked to leave due to being wasted at the space (drugs? alcohol) and when asked to leave threatened violence against Torrie. Reappeared at the space 2 months later and again refused to leave when asked, again threatening violence. It took 7 people and the SFPD to get him to leave.

Junior is the other donation box thief. He has also been 86'd for other reasons as well.

|This guy went into the back classroom and took Rayc's wallet out of his backpack. Rayc saw him with the wallet in his hand and the guy tried to say it was his. He then started running towards the door and was tackled by Jake. We made him show us that nothing was in his pockets, and he kept avoiding the big pocket in the front of his jacket. This pocket turned out to have Sasha's smart phone. During the search his crack pipe fell onto the floor and broke into many pieces. We let him go and told him not to come back.

|Male, early 20's, Asian, black beard and hair, 5′ 8″. Please post photo if available.

For more information on Nyle, see [[85]]. Nyle has been spending a whole lot of time at the space recently - perhaps half his days. He never hacks anything and makes no secret of the fact that he never will. Jesse Z and Alan asked him to not come back repeatedly (February - March '12). If he does come back, please escort him out and tell him that he can explain himself at a Tuesday meeting if he would like to.

|Jonathan was asked not to come back, due to allegations of organizing illegal activities from within Noisebridge and theft. A few days later, he had a proxy return to the space a few days later on his behalf to retrieve blankets, etc. that he'd apparently stashed in the darkroom. However, what his proxy took was apparently not the blankets that he wanted, and he shortly thereafter came upstairs and went into the darkroom, himself leaving with items that appeared to be bedsheets. The fabric his associate had taken was found in a heap at the bottom of the elevator and returned to the darkroom. Several days later, Jonathan returned to Noisebridge with his hand shoved in a gym bag, claiming he had a gun. He continued pushing past people to get into the main space, screaming constantly about killing everyone and then himself, and that everyone was to leave, or he would kill them all. He also claimed that the cops were hot on his trail and would arrive at Noisebridge at any moment, and that he intended to provoke a [http://en.wikipedia.org/wiki/Suicide_by_cop suicide-by-cop]. Not sure on whether or not he did have a gun, people were not taking a chance as they filed for the exit. However, Derek, Jedi, Rayc, Ben, stayed behind, calling him on his bullshit. Four people swarmed him as he made a b-line sprint for the fire escape. They wrestled him to the floor and removed his bags away from him. Jedi arm barred and escorted Jonathan down the stairs to the sidewalk, bringing him over to the quickly-amassing phalanx of squad cars. Immediate consensus was that he is not welcome in the space again.

|Ilya
|[[file:Ilya.jpg|200px|thumb|left|Ilya]]
|This person named Ilya was behaving irrationally, and confused his own backpack with Patricks, causing suspicion that he was intending to steal things. He also put on Patricks' clothes and said he thought people were allowed to use whatever items were in the space. He had some small, and not particularly valuable, items that he had pocketed, and had stashed random, not valuable, items in the bathroom. He was unable to explain his behavior to Dr. J and was handed over to police, who did not take him into custody, and he was told not to return to Noisebridge.

He was with his brother Alex who did not do anything sketchy and should not be banned. -jake

[[Image:Harvey-noisebridge.jpg|200px|thumb|left|Harvey]]
|Older guy with longish gray hair, who has often come to Noisebridge with bedding, and has used Noisebridge as a home from time to time. He has been asked to leave, and not come back. He has come back anyway. He has a gate key -- if you see him, demand that he give you the key.

Here is a link to the meeting where Harvey was banned: 
[[Meeting_Notes_2013_09_10#Proposals_discussed_this_week]] 
And here is the relevant quote: 
:"Harvey is no longer allowed in the space. Has admitted to stealing, was caught sleeping in the stairwell on many occassions, returned items that belonged to multiple residents of Noisebridge. Was seen and accounted for by multiple members of Noisebridge to be digging in other people's belongings. Many tools and properties of Noisebridge were found among Harvey's things."

On 24th September 2014 Harvey attacked Mitch while trying to interfere with the contents of the mailbox. "If you see Harvey ever again, call the police. He bit my thumb tonight to get back the piece of mail he was taking from our mailbox." If you call the SFPD in relation to Harvey cite the case number 140-810-381 in relation to his assaulting Mitch.

Jean-Jacques was repeatedly caught hoarding large quantities of personal stuff in Noisebridge and subsequently lying about its removal from the space. This culminated in the discovery that JJ had filled approximately 60 boxes worth of stuff into the crawl space beneath the first floor in the basement, directly after having been given an ultimatum to remove all his personal stuff from the space be banned.

| Late twenties dude, 5'11. Asked to leave repeatedly by Torrie, Rayc, Rubin and Patrick. Refused to leave the space, made all sorts of claims about folks attempting to discredit their opinions about him. Refused to the point of having the police called. Is associated with Pidgeon and Pirate Mike. Not welcome back in the space.

| Was caught living on top of the building's elevator in February-2014, and was banned for 6 months as a warning. He was caught living in the space again in December-2014. It became difficult to trust him. He wore people out in endless discussions with the repeated claim there was some kind of class conspiracy going on within the community. As a result he used up a lot of bandwidth and became severely disruptive to the Noisebridge community. Rayc is no longer allowed in Noisebridge.

Instead, Robin promised to not return to Noisebridge unless invited back by consensus[https://noisebridge.net/wiki/Meeting_Notes_2014_03_04#Ban_Robin].

| Egon (aka 86me)
|[[File:Egon.jpg|200px|thumb|left|Egon]]
|Very abusive to people in the space.
In late 2014, after being denied access to the space for being super drunk (with PirateMatt), rather than go away, he popped the top door hinges to gain access.
Though often very nice, and helpful, he was asked to stay away from Noisebridge for his abusive and erratic behaviors.
He was banned at Sudo Room for safe space reasons after being abusive there.
He's now reciprocally banned from Noisebridge for safe space reasons.

| Tom Nevin
|
| We suspect that Tom has entered Noisebridge at night and stolen donation money, likely several times. Do not let him in to Noisebridge again.
|-

|-
| Hat / Beer Guy (Gio)
| [[File:Hatbeerguy.png |200px|thumb|left|Hat / Beer Guy being asked to leave]]
| Too often problematically drunk in the space (4 recorded incidents):

- joined a laser class but was too drunk to remember what was taught, asked to leave the class

- drunk in space on Mardi Gras, tried to give someone a mug that said 'codility' on it insisting that it was good stuff

- pretty intoxicated and gave attitude about having to leave when space was being shut down

- got wasted and then came to the hackatorium to announce that he was the King and "what can i get for you", asked to leave for repeated sexually harassing statements

|-
| Rigol
| [[File:Rigol_sleeping.jpg |200px|thumb|left|Rigol Sleeping on the couch in Fox Lounge]]
| Rigol has continually slept in the space despite being asked not to numerous times. He was asked to leave and not come back but has continued to return and continued to fall asleep. When asked to leave he is argumentative but will eventually leave if you keep asking.

|-
| Christopher Presley
| [[File:Chris-p.jpg |200px|thumb|left|Christopher Presley]]
| Chris handed an extremely threatening note to a person in the space. When asked to leave the first time, Chris did not, and was required to be asked again before leaving. He claims to be a CTO of a "Multi-musicality" platform.

|-
| George Mylonas
| [[File:GeorgeM.JPG |200px|thumb|left|George Mylonas]]
| George used several expensive machines in unsafe ways and ignored advice on how to use them correctly. Because of this, he ended up damaging them, but hid this fact. He demonstrated carelessness for how others would be affected by his actions. When confronted, he did not take responsibility for the damage or the carelessness. He is banned from ever returning

|-
| Nicolas H.
|
| Nick has been asked repeatedly to not drink in the space, and he continues to do so. His repeated lying about it, disregard for rules such like sleeping at the space, and causing hindrance to others makes him unwelcome until such a time that he can prove to the community he is able to function within it's bounds.

|-
| Alexander Lee
| [[File:Alexander_lee.jpg|200px|thumb|left|Alexander Lee]]
| Alex repeatedly physically threatened multiple members of the Noisebridge community. He is no longer welcome here.

|-
| Dan Gailey
| [[File:Dpg.jpg|200px|thumb|left|Dan]]
| Dan has been emotionally and physically abusive, to various degrees, towards multiple members of our community.

|-
| Karriem
| [[File:Karriem.jpg|200px|thumb|left|Karriem]]
| Karriem attends meetups claiming to be an angel investor, giving people the impression that he's of significance in tech and in particular in hacker spaces, including Noisebridge. He claims to be extremely knowledgeable about various things, but when he's engaged on them, he quickly departs the conversation. Additionally, he has been hostile toward members of the community trying to address issues with him.

|-
| Omar / Neon / Reynaldo / Ronaldi
| [[File:Omar.jpg|200px|thumb|left|Omar]]
| Omar has been asked to take a break several times for leaving messes, not cleaning up after themselves, and taking food / drinks without paying. Each time, they have returned with the same behavior. He has subsequently also tried to tackle someone who helped to ask him leave the space.

|-
| Andrew
| [[File:Andrew86_1.jpeg|200px|thumb|left|Andrew]] [[File:Andrew86_2.jpeg|200px|thumb|left|Andrew]]
| Andrew was behaving extremely erratically, with delusions and hallucinations about those around him. He accused one person of trying to reprogram him, made multiple racially charged comments towards others, would not leave people alone when asked, and often could not perceive their words when they were speaking to him because of his hallucinations about what they were saying to him. He also tore up the anti-harassment policy and was extremely difficult to remove from the space because of his inability to recognize what was being asked of him, and because of all the stuff he had accumulated around him physically.

|-
| Daniel Telburg
| [[File:Daniel_telburg.jpg|200px|thumb|left|Daniel]]
| Daniel Telburg: we have heard several reports from members of the community that he has raped young women. He is not welcome at Noisebridge.

|-
| Ryan
| [[File:Ryan2.jpg|200px|thumb|left|Ryan]]
| Sudoroom banned Ryan Martin for safe space reasons, stating prolonged intimidation and harassment. Due to reciprocal ban agreements for reasons of safety, he is automatically also banned from Noisebridge. It was noted that he is hard to recognize from this photo. He now has a bit longer hair (though still short) and is a bit bigger than in these photos -- one factor that might help identify him at other spaces is that he has been coming in with his girlfriend (who Sudoroom has no issue with) who has blue hair. November-2017
|-
| Rainbow
| [[File:Rainbow1.jpg|200px|thumb|left|Rainbow]]
| Rainbow was asked to take a break because of her erratic behavior and possible drug use in the space. After the break, the problematic behavior continued. Rainbow is no longer welcome at Noisebridge. September-2017

|-
| Jeff
| [[File:Jeff.jpg|200px|thumb|left|Jeff]]
| Jeff was asked to leave Noisebridge after many conversations. He kept bringing sketchy phones into Noisebridge, thought to be stolen. He was asked about a phone stolen in Noisebridge. He continued to change the OS's on computers after being told not to do so. In all of these occasions he behaved in ways that made people at Noisebridge very uncomfortable.

[[File:ben_woosley2.png|200px|thumb|left|Ben Woosley]]
| Ben Woosley engaged in non-consensual sex (aka rape) with someone who comes to Noisebridge. He acknowledges the sex was non-consensual but insists it isn't rape. He is not welcome at Noisebridge. Feb-2017
|-
| Daily Swa Laurel
| [[File:Daily_swa_laurel.jpg|200px|thumb|left|Daily Swa Laurel]]

|-
| Chris Altman
| [[File:Screen_Shot_2017-01-11_at_7.56.24_PM.png|200px|thumb|left|Chris Altman]]
| Continued to sleep at NB after many warnings. He was asked not to come back but waited a few months and lied his way about his good standing in the space, proving that he cannot be trusted. Chris Altman is not allowed to return to Noisebridge. Jan-2017
|-
| Nick
| [[File:Nick.jpg|200px|thumb|left|Nick]]
| On 10-December-2016 Nick was asked to leave Noisebridge and not to comeback. He verbally abused our downstairs neighbors at Oh Happy Day.

|-
| (name unknown)
| [[File:unknown_name.jpg|200px|thumb|left|(name unknown)]]

|-
| Kyle
| [[File:Kyle.jpg|200px|thumb|left|Kyle]]
| On 1-December-2016 Kyle was visibly intoxicated in the space while using a blowtorch for glass blowing. We asked him to stop using the blowtorch, he refused and was hostile and insulting. He had to be escorted out by a team of people. He is not welcome back.
|-
| Jason
| [[File:Jason.jpg|200px|thumb|left|Jason]]
| After being very helpful and friendly at Noisebridge for several months, others became very concerned and uncomfortable with his growing talk of conspiracies against him at Noisebridge, with hints of violence targeted at those he felt were part of the conspiracy. His erratic behavior and the above threats of violence resulted in Jason being asked to leave Noisebridge at the end of September, 2016.
|-
| Lance
| [[File:lance_combined.png|200px|thumb|left|Lance]]
| Lance was formally banned from Noisebridge in September 2016, although he has previously been asked repeatedly to leave and not come back. He refuses to leave the space peacefully and always requires significant effort to get him to to leave Noisebridge. He is a textbook tweaker, who while peaceful in his interactions with people, mutters threats under his breath.

*Note: He repeatedly tries to come back to the space, even when asked not to return (Once in April 2016, and twice in August/September 2016). He tried to enter again in October 2017. If asked to leave, he is not dangerous, although he is quite vocal.
|-
| Mark Janssen (Xer0Dynamite)
| [[File:Mark_janssen.jpg|200px|thumb|left|Mark Janssen]]
| Mark was banned from Noisebridge due to a history of internet hate speech and having been asked to leave Sudo Room. Noisebridge aims to be a space that is inclusive of people of all walks of life, which means we actively work to exclude those with views of intolerance and threats of violence.
|-
| Mischa Spiegelmock (wooster)
| [[File:Mischa_Spiegelmock.jpeg|200px|thumb|left|Mischa Spiegelmack]]
| Mischa was banned from Sudoroom in March 2015 for being "manipulative, dangerous, acts in bad faith and will knowingly exposes Sudoroom members to violent abuse". He's a known troll and has harassed and targeted individual members of their community. Given The reciprocal ban agreement with Sudoroom he is no longer welcome at Noisebridge
|-
|Diana
|[[File:Diana_ban_photo.jpg|200px|thumb|left|Diana in June-2016]]
|Diana was banned at Sudo Room in June-2016 for physical violence against a member. Since Diana was banned for safe space reasons, they are automatically also banned from Noisebridge. 
According to an email from Sudo Room: "This was an escalation of a dispute between two people who had an existing relationship and Diana lives very close to sudo room so you shouldn't worry overly about a problem at other hackerspaces." And from the Sudo Room "Asked to Leave" page, Diana "Additionally has been using the space as their living room (playing WoW all day) and caught sleeping at least twice."
|-
|David/Bunny
|[[File:David_Bunny2.jpg|200px|thumb|left|Bunny in March 2016]]
|Asked to take a break in March-2016 after some misunderstandings, but he came back asking at least one person in the space to not tell Mitch or Rubin that he was in the space, and was seen taking away an item of high value. He returned the item, but is no longer welcome at Noisebridge.
|-
|Adam
|[[File:Adam.jpg|200px|thumb|left|Adam in December 2015]]
|Asked to leave having been caught stealing from others in the space.

At several points misused the space in the creation of his "art", hiding large amounts of "art" around the space.

Was caught sleeping in the elevator overnight in late November 2015.

Was asked to take a break in late November 2015 after the sleeping incident and initially agreed to do so, but then returned repeatedly to the space claiming that nothing was wrong.

When confronted about his theft of another member's property he became irate and threatening to them.

Should not be allowed into the space under any circumstances.

|Shawn Landden
|[[File:ShawnLandden.jpg|200px|thumb|left|Shawn Landden 2013]]
[[File:shawn_landden_beard_102915.jpg|200px|thumb|left|Shawn Landden 2015]]
|Banned by consensus. See [http://pastebin.com/82m0uhC4 here] and [https://www.noisebridge.net/pipermail/noisebridge-discuss/2013-March/034968.html here].

If Shawn returns, immediately call the police. State he's trespassing, and he has a violent history of assault against individuals and law enforcement.

|Darren "Crystals Guy"
|[[File:darren_crystals_1.jpg|200px|thumb|left|Darren in Feb 2016]]
|Was asked to leave after spreading his rocks over the hackatorium tables.
Hid salvaged electronics boards that were in the hack shelves onto the top of a high bookshelf, apparently for no reason.
Has a compost bin full of sandy rocks he considers crystals.
Became angry, yelling at multiple people.

Should never be allowed back into the space.

[[File:darren_crystals_2.gif|left|Darren in Feb 2016]]

|-
|Matt the tweaker
|[[File:mattthetweaker.jpg|200px|thumb|left|Matt the tweaker]]
|Matt carries a backpack full of shower rings twisted with tangle therapy tangles. He has converted his brain into a computer and is using it to solve the tangles with an algorithm. He is quiet and not aggressive, but very fixated on his tangles and can't form a completed thought, continuing on until you interrupt him.

Persistently tell Matt that "you have to leave now" and walk him out. He will go about 5 feet at a time but is not aggressive.

[[File:Clayton_Hill_2.jpg|200px|thumb|right|Clayton Hill]]
|Asked to leave due to being wasted at the space (drugs? alcohol) and when asked to leave threatened violence against Torrie. Reappeared at the space 2 months later and again refused to leave when asked, again threatening violence. It took 7 people and the SFPD to get him to leave. Do not under any circumstances let into Noisebridge. He's to be considered violent and unpredictable

|This guy went into the back classroom and took Rayc's wallet out of his backpack. Rayc saw him with the wallet in his hand and the guy tried to say it was his. He then started running towards the door and was tackled by Jake. We made him show us that nothing was in his pockets, and he kept avoiding the big pocket in the front of his jacket. This pocket turned out to have Sasha's smart phone. During the search his crack pipe fell onto the floor and broke into many pieces. We let him go and told him not to come back.

|Male, early 20's, Asian, black beard and hair, 5′ 8″. Please post photo if available.

For more information on Nyle, see [[85]]. Nyle has been spending a whole lot of time at the space recently - perhaps half his days. He never hacks anything and makes no secret of the fact that he never will. Jesse Z and Alan asked him to not come back repeatedly (February - March '12). If he does come back, please escort him out and tell him that he can explain himself at a Tuesday meeting if he would like to.

|Jon(athan)

[[file:Jon-2.png|200px|thumb|right|Jon]]
|Jonathan was asked not to come back, due to allegations of organizing illegal activities from within Noisebridge and theft. A few days later, he had a proxy return to the space a few days later on his behalf to retrieve blankets, etc. that he'd apparently stashed in the darkroom. However, what his proxy took was apparently not the blankets that he wanted, and he shortly thereafter came upstairs and went into the darkroom, himself leaving with items that appeared to be bedsheets. The fabric his associate had taken was found in a heap at the bottom of the elevator and returned to the darkroom. Several days later, Jonathan returned to Noisebridge with his hand shoved in a gym bag, claiming he had a gun. He continued pushing past people to get into the main space, screaming constantly about killing everyone and then himself, and that everyone was to leave, or he would kill them all. He also claimed that the cops were hot on his trail and would arrive at Noisebridge at any moment, and that he intended to provoke a [http://en.wikipedia.org/wiki/Suicide_by_cop suicide-by-cop]. Not sure on whether or not he did have a gun, people were not taking a chance as they filed for the exit. However, Derek, Jedi, Rayc, Ben, stayed behind, calling him on his bullshit. Four people swarmed him as he made a b-line sprint for the fire escape. They wrestled him to the floor and removed his bags away from him. Jedi arm barred and escorted Jonathan down the stairs to the sidewalk, bringing him over to the quickly-amassing phalanx of squad cars. Immediate consensus was that he is not welcome in the space again.

|Ilya
|[[file:Ilya.jpg|200px|thumb|left|Ilya]]
|This person named Ilya was behaving irrationally, and confused his own backpack with Patricks, causing suspicion that he was intending to steal things. He also put on Patricks' clothes and said he thought people were allowed to use whatever items were in the space. He had some small, and not particularly valuable, items that he had pocketed, and had stashed random, not valuable, items in the bathroom. He was unable to explain his behavior to Dr. J and was handed over to police, who did not take him into custody, and he was told not to return to Noisebridge.

He was with his brother Alex who did not do anything sketchy and should not be banned. -jake

|Older guy with longish gray hair, who has often come to Noisebridge with bedding, and has used Noisebridge as a home from time to time. He has been asked to leave, and not come back. He has come back anyway. He has a gate key -- if you see him, demand that he give you the key.

Here is a link to the meeting where Harvey was banned: 
[[Meeting_Notes_2013_09_10#Proposals_discussed_this_week]] 
And here is the relevant quote: 
:"Harvey is no longer allowed in the space. Has admitted to stealing, was caught sleeping in the stairwell on many occassions, returned items that belonged to multiple residents of Noisebridge. Was seen and accounted for by multiple members of Noisebridge to be digging in other people's belongings. Many tools and properties of Noisebridge were found among Harvey's things."

On 24th September 2014 Harvey attacked Mitch while trying to interfere with the contents of the mailbox. "If you see Harvey ever again, call the police. He bit my thumb tonight to get back the piece of mail he was taking from our mailbox." If you call the SFPD in relation to Harvey cite the case number 140-810-381 in relation to his assaulting Mitch.

| Late twenties dude, 5'11. Asked to leave repeatedly by Torrie, Rayc, Rubin and Patrick. Refused to leave the space, made all sorts of claims about folks attempting to discredit their opinions about him. Refused to the point of having the police called. Is associated with Pidgeon and Pirate Mike. Not welcome back in the space.

[[File:Rayc2.jpg|200px|thumb|left|Rayc]]
| Was caught living on top of the building's elevator in February-2014, and was banned for 6 months as a warning. He was caught living in the space again in December-2014. It became difficult to trust him. He wore people out in endless discussions with the repeated claim there was some kind of class conspiracy going on within the community. As a result he used up a lot of bandwidth and became severely disruptive to the Noisebridge community. Rayc is no longer allowed in Noisebridge.

|Robin Noel
|[[File:Robin.jpg|200px|thumb|left|Robin Noel]]
| Was proposed for banning due to use of racial slurs, deliberate intimidation, and harassment[https://noisebridge.net/pipermail/noisebridge-discuss/2014-February/042574.html]. Instead, Robin promised to not return to Noisebridge unless invited back by consensus[https://noisebridge.net/wiki/Meeting_Notes_2014_03_04#Ban_Robin]. His membership was subsequently suspended[https://noisebridge.net/wiki/Meeting_Notes_2014_03_11#Proposals_from_last_week]. Subsequently, he threatened Noisebridge with legal action[https://www.noisebridge.net/wiki/Meeting_Notes_2014_03_25]. Robin is not welcome back in the space.

| Egon (aka 86me)
|[[File:Egon.jpg|200px|thumb|left|Egon]]
|Very abusive to people in the space.
In late 2014, after being denied access to the space for being super drunk (with PirateMatt), rather than go away, he popped the top door hinges to gain access.
Though often very nice, and helpful, he was asked to stay away from Noisebridge for his abusive and erratic behaviors.
He was banned at Sudo Room for safe space reasons after being abusive there.
He's now reciprocally banned from Noisebridge for safe space reasons.

== Who can use the laser cutter ==

Only people who have been trained by an official trainer can use the laser cutter, in order to prevent unintended damage to the machine, operator, and Noisebridge.

Full list: [[Laser_Manual/Who_can_use_the_laser_cutter]]

== How to get trained to use the laser cutter ==

==== Route 1: DIY ====
# Read through the tutorial (currently unavailable)
# Ask a trainer if they will verify the content you learned in the tutorial
# Get your name on the list of users before the first time you use the machine

==== Route 2: Laser Safety Class! ====
# Laser safety training classes are posted on our [https://www.meetup.com/noisebridge Meetup]. Size is limited to 5 students, so that everyone can see how to operate the laser.
# Get trained
# Get your name on the list of users before the first time you use the machine

The laser training class is pay-what-you-can, and the recommended minimum donation is $20.

== Basic Safety ==
The laser cutter is generally a very safe machine to use. However, as with all industrial machines, you need to treat it with respect. The main safety concerns are creating fires, hurting your eyes or skin, getting crushed by the machine, and creating toxic fumes.

The basics:
* ALWAYS MONITOR THE LASER BEAM CUTTING YOUR WORK!
* DO NOT STARE DIRECTLY BECAUSE BURN-GENERATED VISIBLE LIGHT IS VERY BRIGHT!
* USE YOUR PERIPHERAL VISION!
* OPEN THE LID if you see a fire
* BLOW IT OUT if the fire keeps burning
* DON'T CUT UNAPPROVED MATERIALS!
* MAKE SURE THE WINDOWS BY THE BATHROOM ARE CLOSED SO YOU DON'T FUMIGATE NOISEBRIDGE

=== Fire ===

[[Image:Laser_water_estop.jpg|thumb|right|upright=3|alt=Laser cutter with water and estop| The water squirt bottle is sitting on top of the laser, and the estop is the round red button.]]

You can really hurt yourself or burn the building down with this machine. If you follow the safety rules, the chances of you causing this is close to zero. Some materials are very flammable on the laser cutter, and shouldn't be cut. Never cut an unapproved material, or a material you can't identify. A laser beam can also initiate a fire if the speed of the cut is too slow or the laser power is set too high.

Ways to not cause fires:
* ALWAYS MONITOR THE LASER CUTTER WHENEVER IT IS CUTTING AS FIRES CAN HAPPEN. The laser affects your material by heating it. Your job can change in seconds with the accumulation of heat in your material. Never leave the room while the laser is in operation. If you leave the laser unattended, your access to the laser cutter will be permanently revoked.
* Use reasonable speed/power settings. Start with the recommended speed/power settings for your material. Be patient - resist the temptation to crank the power and speed to rush through your job. This can cause fires.
** There will be some light when material is cut. This light at the point of lasing may be ok as long as it stays with the motion of the laser. If a flame appears while the laser is in operation, stop your job and try again with lower heat settings.
* Know where the fire extinguisher is in case of a fire. The ONLY fire extinguisher that should be used on the laser cutter is the halotron extinguisher right next to the laser cutter. Other fire extinguishers are corrosive and will ruin the machine.

How to put out a fire:
* Push the estop. (To turn the machine back on after the estop was hit, you need to switch the power switch on the right hand side of the machine off and on again).
* Open the lid.
* If it's small, try and blow it out.
* If it's smallish, try and squirt it out with the water squirt bottle sitting on the right hand side of the machine.
* If that doesn't work, use the halotron fire extinguisher to the right of the laser cutter. Aim it at the base of the flame.

=== Damage to eyes and skin ===
The laser beam can instantly and permanently blind you. It can also burn your skin.
* The lid's window will block the infrared laser beam, but it doesn't block the visible light produced by the burn. THE VISIBLE LIGHT CAN BE BRIGHT ENOUGH TO DAMAGE YOUR RETINA! DO NOT STARE DIRECTLY AT THE CUT! Use your peripheral vision.
* You don't ever want any part of your body in contact with the beam.
* As long as the door is closed, you're safe to look at the laser. There are interlocks on the door that help ensure the laser never operates with the doors open. Don't disable them.

=== Crushing danger ===

The laser cutter is a dumb machine. It doesn't care whether your hand is in the way when it's moving. The head can move when the door is open. Always make sure everyone's hands are out of the machine before moving the head.

Also be very careful not to crash the head into other parts of the machine. Be very careful when moving the z-axis to not crash the head into the bed, and to not move the z-axis if the focus length acrylic circle is under the lens.

If you need something to weigh down your material, use the magnetic balls or beanbags that are kept near the laser; nothing else. Do not let the laser head crash into these; if it does immediately stop the job.

Be *very* careful to not put the beanbags (or any other material) in such a situation where they may be dragged by the head. The head should never bump into anything, and *especially* never drag anything.

=== Fumes ===
The laser cutter burns the things it's cutting, which can create toxic fumes.
* ONLY CUT APPROVED MATERIALS. Cutting nonapproved materials can release really toxic gases, including chlorine and cyanide. These are really bad for humans, as well as being very damaging to the laser cutter.
* The ventilation fan should always be running if the laser cutter is on, even if it's not cutting. It's currently wired such that you can't turn on the laser cutter without the fan turning on, but please make sure it's running.

== Care of the machine ==

'''Please don't perform any maintenance on the machine (including cleaning lenses/mirrors or aligning mirrors) unless you've specifically trained on it.'''

The laser cutter is finely calibrated piece of machinery. Please close the lid gently, and do not push or jar the machine at any time. Do not lean or press on the tray - it's fragile, and needs to be perfectly flat for the laser cutter to cut properly. If you take the honeycomb bed or slats out, please be ULTRA CAREFUL with them - put them somewhere where they won't get damaged or warped.

== Paying for your laser time ==

The laser cutter has parts that wear out over time, which can be quite costly to replace, especially the laser tube. A new tube costs several thousand dollars. Thus, we require people to pay for the time on the laser they use, so we can pay for new parts. The cost for using the laser cutter is $5 per hour of cutting time.

To figure out how much time your job takes, press the File button, select your file, and then select Work Time from the menu. It will tell you in hours:minutes.seconds.

There is a laser cutter donation box on the wall of the Sparkle Forge room. Please pay for the cutting time you actually use, even if you end up running your job multiple times.

== Workflows ==

=== Overall Workflow ===

This is the overall structure of the workflow. Each part is elaborated below.

# Laser start up
# Material setup
# Convert file to DXF
# Load file onto the machine
# Dry run
# Cut/Engrave
# Laser shut down
# Cleanup

=== Laser start up ===

[[Image:Laser_chiller.jpg|thumb|right|upright=3|alt=Laser chiller| The laser chiller is the box on the bottom left of this photograph. If the laser doesn't beep when it turns on, you should turn on the chiller manually.]]

# Turn on power and ensure that the fan and chiller are running. If you do not hear beeps when the laser starts up, the chiller is not running and you must turn it on.
# Move the head as far forward and right as possible, close to the controls

=== Material setup ===

# Clean the bed of any scraps that may be on it
# Move the cut head as far forward and right as possible (near the controls)
# Raise the laser head as far up as possible
# Raise the bed to the desired height, watching the laser head to avoid crashes
# Move the laser head as far back and right as possible
# Place material on the bed
# Focus the laser (do at least for each distinct thickness, optimally do for each piece of material)

=== Focusing the laser ===

[[Image:Laser_shelf.jpg|thumb|right|upright=3|alt=Shelf by laser cutter | This is the shelf to the left of the laser cutter. The acrylic disks used for focusing the laser are in the toolbox with the yellow lid.]]

Noisebridge has acryllic disks cut to various thicknesses that can be used to accurately focus the laser. Specifically the laser head needs to be locked to 8mm above the surface of the material you're cutting.

# Place the material on the cut bed
# Move the cut head to the center of the area to cut, watching the laser head to avoid crashes w/ material
## Note that the honeycomb bed can move up and down (Z-axis) so if the material doesn't fit under, hit Z/U on the laser controls and navigate the menu until Z axis (or something similar) is selected. Then use the left and right arrows to move the bed up and down.
# Loosen the wing nut and raise the head all the way up
# Place the focusing discs on the material under the head
# Lower the head until it just touches the focusing disc (8mm above material)
# '''When you focus the laser, ALWAYS make sure the metal adaptor for the air hose is facing straight towards you'''
# Lock the head in place (tighten the wing nut)
# Remove the focusing discs

=== Convert an image in Inkscape to a DXF file ===

# Load the image into Inkscape
# Set the different cut paths to different colors (for controlling settings, etc.)
# Perform any debugging steps (by default you should perform all of them b/c of errors in the laser software)
# Save as a DXF. Be sure to make the units be millimeters so that importing later will correctly scale the image.

=== Debugging DXF Problems ===

Sometimes exporting to DXF introduces bizarre extra lines. There are two things to try to debug. The first is to convert objects to paths:

# Select all the problematic shapes
# Path > Object to Path

If this fails to resolve the issue, you can try a more radical solution which will eliminate all bezier paths entirely:

# Select all the problematic shapes
# Convert bezier paths to lines (Extensions > Modify Path > Flatten Bezier).

Flatness 0.5 is good to start with. Smaller = better approximation of the curves. A lower flatness number takes more time to compute, but also produces a better approximation to the curve. Be sure to ungroup (sometimes multiple times) before trying this, as grouped objects cannot be flattened as a group. This is especially important for text which is by default a group (each character being a separate object in Inkscape once you've turned it into a path).

Sometimes need to select the path's directly with the path tool (but not the points!).

Also see http://www.pstoedit.net/ for conversion from svg to dxf files.

=== Loading into the laser cutter software ===

# Import the file with File > Import
# Resize as needed, tho if the file was exported w/ millimeter units, the software should also import the image with the correct size.
# Set the cut order:
##* EITHER Set the cut order to inside-out (Handle > Cut optimize > Inside to outside)
##* OR Manually specify cut order with the Set cut property tool (Edit > Set cutting property). See below for more details.
# Set the speed and power for the layers as necessary, and the process mode for each layer to either cut (for continuous line cutting) or dot (for dashed line cutting) or scan (for engraving)
# Optionally, simulate the cutting/engraving process.
# Download to the machine (Laser Work panel on the bottom right).

=== Manually specifying cut order ===

In the Set cutting property window (Edit > Set cutting property), you can manually re-order the cut paths. In the window, you'll see an image of the workpiece, and to its right, two lists of paths. When you first open the window, all of the cut paths are in the left. If you select a path (either in the image or in the list) and click the button labeled ">>", this path will be transferred to the end of the right list of paths. If you click ">>>", all of the paths in the left list will be moved to the end of the right list (preserving order). Similarly, clicking "<<<" will move the right list to the end of the left list. If you select a cut path in the right list, the up and down arrow buttons will reorder that path in the chosen direction.

=== Loading speed and power settings from library ===

# In the top right panel, double click the layer of interest
# Click "Load parameters from library"
# Select the library item
# Click "Load"

=== Saving power and speed settings to library ===

# In the top right panel, double click the layer of interest
# Make sure the layer is set to the desired parameters
# Click "Load parameters from library"
# Click "Save as"
# Enter a name and optionally some notes
# Click "Ok"

=== Simulation ===

# Open the simulation window with either Edit > Preview or the toolbar button labelled with a monitor.
# Click the Simulation button in the right panel

=== Cutting ===

# Select the file to use using the File button
# Move the head to the initial guess origin with the arrow buttons
# Test the frame with the Frame button adjust origin as necessary
# Set the origin by pressing Origin
# Test the cut by turning the laser power off and pressing the Start/Pause button
# Turn the laser power on
# Cut by pressing the Start/Pause button
# It is generally a good idea to put the laser head into one of the top corners and resetting origin before opening the laser if you plan on adding new material to avoid collisions with a moving head.

=== Engraving ===

In the laser software, open the layers you wish to engrave in the layer parameters panel, and send the processing mode to "Scan". This will do a raster scan of the region bounded by the paths in that layer. An even-odd rule is used to assign regions to the "inside" vs "outside" of the engraving.

=== Cancel a cut/dry run ===

# Pause with the Start/Pause button
# Cancel and move back to the origin with the Esc button

=== Laser shut down ===

# Move the head as far forward and right as possible (near the controls)
# Raise the laser head as far up as possible
# Set origin with the origin button (this helps avoid the laser swinging across the bed later)
# Let the fan run for a little bit (~30 seconds)
# Turn the power off

=== Cleanup ===

[[Image:Laser_tray.jpg|thumb|right|upright=3|alt=Laser bottom tray| This is the bottom tray of the laser, which should be cleaned out after use.]]

# Remove pieces of material scrap left on the bed
# Open the tray door on the front bottom and empty the scraps left there

=== Calculating work time ===

On the computer:

* Open the simulation window (see above). Total work time and time of laser use are displayed in the top right. Donations should be calculated by laser use, not total work time.

On the machine:

* Whole file: File > Select file > Right Arrow > Work Time > Enter
* Current run: Pause the cut, then check time at the bottom right

== Fusion 360 ==
Fusion 360 is a free CAD (Computer Aided Design) program from Autodesk for designing 3D parts, and arguably the best one currently available. If you're designing something complex on the laser cutter, particularly with multiple parts that need to fit together, I highly recommend it over drawing programs like Inkscape. It also has CAM (Computer Aided Manufacturing) capabilities, which makes it very useful for CNC machining and laser cutting. There's a copy of the software on the laser cutter computer, and you can download it [http://www.autodesk.com/products/fusion-360/overview here]. It's free as long as you make less than $100k per year using it.

=== Workflow 1: The Quick and Dirty Way ===
This is the fastest way, and works a lot of the time
# Make sure your sketch only contains straight lines, arcs, and circles, and no spline curves. If your sketch has splines, go to [[#Workflow 3: The Long Way]]
# Make sure your part is designed using a single sketch, and that you want to cut all the lines in that sketch. If not, go to [[#Workflow 2: The Middle Ground]]
# Right click on your sketch and click Save As DXF
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]

=== Workflow 2: The Middle Ground ===
If you're not sure, this is probably where you should start.
# Make sure your sketch only contains straight lines, arcs, and circles, and no spline curves. If your sketch has splines, go to [[#Workflow 3: The Long Way]]
# Right click on the top surface of the part you want to cut, and click Create Sketch
# Hit the P key to open the Project dialog box, then select the top surface of your part, and any other lines you want to cut
# Hit OK, then remove any lines you don't want cut
# Open the Sketches folder near the top of the tree, then right click your new sketch and click Save As DXF
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]

=== Workflow 3: The Long Way ===
This allows more complicated things like exporting splines, which doesn't work with the above methods, kerf compensation, which makes your parts fit together snugly, but you can also use the above methods and then do it in RDWorks, or lead-ins and lead-outs, which can make for a cleaner cut, but I can't figure out how to get RDWorks to import correctly.
# Design a part to be laser cut by drawing a 2D sketch and extruding it
# Go to the CAM workspace by clicking the Model button in the top left, then selecting CAM
# Select the Waterjet operation (if you don't see this, turn it on under Preferences -> Preview)
## Set Type to Laser Cutting
## Select the Cutting Mode, either Through - Auto or Etch
## Look up the kerf of the material you're cutting in the [[#Known good materials]] section, and enter that in Kerf Width, or if your material's not listed, cut one a [http://www.thingiverse.com/thing:1166680 kerf gauge] and put the result in the wiki. The kerf changes depending on the thickness, speed and power. Setting a larger kerf width will make your parts fit tighter, and setting a smaller kerf will make them looser.
## Select the contours of your part that you want to cut
## Go to the Passes tab, and change Compensation Type to In Computer
## Hit OK to close the dialog box, and you can see a preview of your tool path. You can go back to edit it by double clicking the contour operation in the tree on the left
# To export to DXF, click the Post Process button, which says G1 G2. Make sure rdworkslaser is selected as your post processor, type a name for the export and hit Post. Then select the folder to put it in.
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]
# Fusion automatically orders the cuts from inside out and in the fastest order, but RDWorks doesn't always respect that order, so you may need to optimize the cut order again

=== Advanced Options ===
# If you're using your own computer for the first time and not the laser cutter desktop, you have to enable the laser cutter support which is still in beta, by clicking on your name in the top right, then Preferences, Preview, and checking "CAM - Waterjet/Laser/Plasma cutter support". You will also need to download the custom post processor that we use for this laser.
# There's a simulate button to the left of the Post Process button, if you want to do it in Fusion
# If you want to disable or tweak the lead ins and lead outs, you can go to the Linking tab. Lead ins and lead outs can fix the bump you get on the side of your part where the laser started and stopped, but they also make extra cuts in your scrap material, which you may want to keep. In this tab you can also specify the Entry Position for each cut path.
# You can disable Kerf Compensation by settting Sideways Compensation to Center under the Passes tab, though this is not recommended

== Techniques ==

=== Kerf Compensation ===

For any given layer, you can compensate for the kerf (width of the cut) by opening it's settings and clicking the "Advance" button next to the "Seal" input box towards the middle-bottom. Enable sew compensation, and pick the direction and sew width (kerf size). The inward direction will make the actual cut move toward the inside of a closed cut path, outward will move it towards the outside.

In general, for cuts on the outside, you want to move outward, to move the actual cut edge be exactly where the path is in your design. For cuts on the inside, you want to use the inward direction.

=== Negative Space Engraving ===

You can engrave a vector shape with a hole in the middle of it, so that you get enclosed portions that are not engraved in the middle of fully engraved portions. To do this, when you construct the image in your editor of choice, simply perform subtraction between the relevant paths, to remove the inner part. In the RDWorks laser software, the two paths will show up, and be independently editable (making them look like just two distinct paths to engrave), but they will engrave correctly as a negative space. Obviously test this w/ your software; this technique is known to work using Inkscape.

=== Nest & Waste Less Material ===

As of 01/2018 you can use the industrial strength [http://deepnest.io/#quickstart Deepnest] installed on the [[Kaitian_CM1309|Laser Cutter computer]] + [[CollaborationStation|Collaboration Station]] in Hackitorium. We have an unlimited subscription available to laser users, which is compatible with both ''DXF'', ''Corel CDR'' and ''SVG'' formats. Please ask if you need login credentials. Also available from the same author for free is [http://svgnest.com/| SVGNest, which can be used by clicking here].

=== Text Cutting ===

In Inkscape, after converting the text object to a path, it's necessary to ungroup the text as well, to create separate paths, prior to flattening the bezier curves.

If you're using a cursive font and want everything to be one piece, convert the text object to a path, and use Path > Union. This tool in general is quite useful for merging paths that have been independently drawn but need to be merged into a single path. For example, if you made two overlapping circles, without this the cutter would just cut the two circles, which leads to a lemon-shaped piece in the center. If you union the paths, it will cut an outline as well. Path > Union will not make any holes in the figure go away, it only gets rid of cuts passing through area covered by another shape.

Engraved text requires no other special technique because no cuts are made, but text cutting is non-trivial. Because of loops, it's sometimes desirable to use a stencil font, especially at smaller scales where legibility is important. 1001 Fonts has a number of stencil fonts for free. At 10pt, some good fonts are Marsh, Spacedock, and Allerta.

== Troubleshooting ==

=== File doesn't appear in laser cutter after successful download ===
If the laser cutter has 99 files loaded into it, new files will not show up. To fix this, open up RDWorks8, and on the right side, select the Doc tab. Inside that tab, click Read to read all the files in the laser cutter, and then click Delete all.
[[Image:laser_cutter_read_files.png|thumb|right|upright=3|alt=read files | This is the button used to read stored files from the laser cutter.]] [[Image:laser_cutter_delete_all_files.png|thumb|right|upright=3|alt=delete all files | This is the button used to delete all stored files from the laser cutter to make room for new ones.]]

== Chlorine material test ==

Before you cut any new material you *must* check that it is safe to cut; specifically that it will not produce chlorine gas when it is burned by the cutting laser. Chlorine is extremely dangerous in its gaseous form and so must be avoided at all costs.

To test a new material, you'll need a sample of the material, a small copper rod (about the thickness of a coat hanger), a pliars, and a handheld propane torch. We'll test for the presence of chlorine by burning a sample of the material in a high temperature propane flame and observe the visible emission spectra. Chrlorine produces a bright green light when burned, and so will be very obvious when you're testing your material.

First, turn on the ventilation on the Sparkle Forge. The switch for this is under the sign that says "For Non-Laser Fires Only", and above the non-laser fire extinguisher. Then, light the propane torch and set it to rest upright on a stable surface. Taking the pliar, hold the piece of copper in the blue part of the flame to heat it. As the copper begins to heat sufficiently it'll cause the flame to turn an orange color. A consistent orange color means that the copper has no residue material on its surface and so is clean enough to use as a test. If you observe non-orange flames when you burn the copper you may need to clean in further, either by waiting for the excess material to burn off, or by scrubbing the surface of the copper when it has cooled.

Once the copper is burning, take the hot copper and melt a sample of the new material onto it. For example if you were testing a new form of plastic you can roll the hot copper rod on the material, melting some of it onto the copper rod's surface.

With this done, place the copper rod back into the blue part of the flame. Observe the colors of the emission spectra from the new material burning. If you observe a bright green color, then the material contains chlorine and thus *must not* be burned further. Ventilate your surrounding area to avoid breathing it in. If you observe no green color as you burn your material sample, then the material is likely safe to use with the laser cutter.

Here is a video example by Zach in NYCResistor with a known good and known bad material: https://www.youtube.com/watch?v=D0_4NLmeSTI

| Vinyl || Most contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| PVC Foams || Most contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| Foam Core || Usually made with PVC which is harmful as listed above.
|-
| Styrofoam || Can cause flash fires
|-
| Polycarbonate or PETG || Does not cut. TAP plastics sells both this and acrylic. '''Be sure to read your labels when purchasing material'''. Lexan is the trade name for Polycarbonate, while Plexiglass is the trade name for acrylic.
|-
| ABS || Gives off hydrogen cyanide which can kill you and also may damage the laser optics.
|-
| Fiberglass || Contains complex epoxies which will cause fires, chlorine, and cyanide. Also contains glass which will not cut.
|-
| Metals || Cannot be etched by this type of laser. Also is harmful as the reflective surface may cause the laser to be reflected back up to the head, damaging it. If someone claims to be etching metal using this type of laser then they are etching a metal with a plastic coating, anodized surface, or some other etchable surface on top.

== Known good materials ==

These materials are known to be ok for use with the laser cutter. The speed and power of the laser cutter will need to be set appropriately for the material and thickness in use. Below is a table showing the suggested settings when cutting or etching them.

|-
| Acrylic (1mm) || 400 || 5 || 30 || 20 || 0.15mm || || || The plastic has a tendency to stick back onto itself a little after cutting because it's so thin, so you may have to pop your pieces out

|-
| Acrylic (2mm) || 400 || 5 || 30 || 20 || 0.15mm || || ||

|-
| Acrylic (3mm) || 400 || 5 || 20 || 55 || 0.15mm || || || Engraving: Power setting 4 and 5 have little visible difference except some minor lightening at the beginnings of cuts at power 4. Power 3.5 produces very light engraving, almost non-existent, with no engraving at the beginnings of cuts. Above power 5, little difference is visible, but powdery soot becomes more prevalent. Power 5 seems to be the best setting to produce frosted effects. If you are engraving with the paper still on, you may want to go higher (do a test)

|-
| Acrylic (19mm / 3/4 inch) || 400 || 5 || 2 || 98 || 0.5mm at surface of cut, 0.15mm at bottom of cut || || || Focal length is 4mm, one pass only. Peel off the top film of the acrylic. **The current settings does not guarantee a clean cut -- you may have to knock your pieces out because the bottom didn't quite go all the way through all the time. If you want to guarantee a clean cut and don't mind it being really slow you can use 1 speed 30 power, just keep an eye on it (slightly flamey)

|-
| Balsawood (3.2mm) || 400 || 5 || 50 || 10 || || || || Engraving balsa produces little differences in power above 5, and below 3.5 or so, there's no engraving at all.

|-
| Balsawood (1.6mm) || 400 || 5 || 50 || 7 || || || || Engraving balsa produces little differences in power above 5, and below 3.5 or so, there's no engraving at all.

|-
| Bamboo (3/32" nominal, 2.5mm actual) || 400 || 3-20 || 55 || 45 || || || || Engraving power 3% produces visible, but very light, marking w/ no depth, 20% produces darker marking but w/ significant depth

|-
| Basswood (1.5mm) || 400 || 5-20 || 50 || 15 || || || || Engraving above power 20 seems to produce no difference in color, only depth, see reference piece in toolbox.

|-
| Birch (1/4 inch plywood from Discount Builders Supply) || || || 15 || 55 || || || || The actual thickness of this stuff varies a lot throughout the sheet, plus there are knots in the wood that are harder to cut through. These settings should work though.

| Redwood (20mm) || 100-400 || 55 || 3 || 55 || || || || 5mm/s gets you almost there, so you could probably go over it a second time and it would work instead. Or if you sand it down a bit, that would probably work. I've only tried engraving on max power. You won't get a consistent depth, and it will vary depending on the grain of the wood. Looks col, but just be aware.

|-
| Red Oak (0.25 inch) || 400 || 23 || 12 || 55 || || || || Engraving power 23 gives a dark engrave on a .5-1 mm line thickness. 12-18 gave a lighter engrave. When cutting a knot in the wood, you'll have to use a lower speed, 9-10 will probably work. This wood was high quality scroll wood with almost no knots.

== Sourcing Material ==

In general, you can get stuff from Amazon, but you have to wait for shipping.

For plastics: [http://www.google.com/maps/place/TAP+Plastics/@37.7711648,-122.4207603,17z/data=!3m1!4b1!4m5!3m4!1s0x808f7e27351bb079:0x7e3610d7dc178b10!8m2!3d37.7711648!4d-122.4185663 Tap Plastics] is nearby Noisebridge, but is expensive, [http://eplastics.com eplastics] is cheaper but you need to wait for shipping, and [https://www.google.com/maps/place/Mr.+Plastics/@37.7091519,-122.1546962,17z/data=!3m1!4b1!4m5!3m4!1s0x808f8fe7938349a3:0xafcb2526326faccd!8m2!3d37.7091519!4d-122.1525022 Mr. Plastics] is cheapest but is in San Leandro.

For woods: [http://www.google.com/maps/place/Discount+Builders+Supply/@37.7704879,-122.4191311,15z/data=!4m2!3m1!1s0x0:0x3c0d6c6e25a89652?sa=X&ved=0ahUKEwjV87WU-JzOAhUI6WMKHSPABOUQ_BIIeTAK Discount Builder Supply] is nearby.

== How do I send files to the Laser computer over the internet? ==

Send your files directly to the laser cutter through this URL [https://cloud.disroot.org/s/bFv70wtK9xQuyp3], which is kindly hosted for us by [https://disroot.org/en| Disroot.org] via [https://nextcloud.com/| Nextcloud].

All files are uploaded directly to ''\My Documents\PUT YOUR FILES HERE (IN YOUR OWN FOLDER)\Uploads for Noisebridge Lasercutter\''

Please move any files you upload to your own folder asap.

== Ok, I created a folder for my laser cutter files, but can I access them over the internet? ==
Yes, this is now possible as of 01/2018.

# Double check you made a folder inside ''\My Documents\PUT YOUR FILES HERE (IN YOUR OWN FOLDER)\''
# Ping @James on Slack with the name of your folder.
# Be sure to mention if you need a password added to your folder.
# Wait a day for the share link to be activated and sent to you.

== Troubleshooting ==

=== Help! All the menu options turned to gibberish! ===
The RDWorks software can be buggy. Go to the top menu, the right-most or or 2nd-right-most tab will have a Language option. Select English.
When that happens, the bed size settings might also have changed. Double check Config -> Document Settings (?). The proper settings are 1300mm × 900mm.
(TODO: need to double check the exact menu labels, doing this from memory at the moment)

=== SOLIDWORKS ===
Apparently DXFs exported from Solidworks (at least v 2017) break when directly imported into RDWorks. The workaround is to import the DXF into Inkscape and re-export it from there.

== Who can use the laser cutter ==

Only people who have been trained by an official trainer can use the laser cutter, in order to prevent unintended damage to the machine, operator, and Noisebridge.

Full list: [[Laser_Manual/Who_can_use_the_laser_cutter]]

== How to get trained to use the laser cutter ==

==== Route 1: DIY ====
# Read through the tutorial (currently unavailable)
# Ask a trainer if they will verify the content you learned in the tutorial
# Get your name on the list of users before the first time you use the machine

==== Route 2: Laser Safety Class! ====
# Laser safety training classes are posted on our [https://www.meetup.com/noisebridge Meetup]. Size is limited to 5 students, so that everyone can see how to operate the laser.
# Get trained
# Get your name on the list of users before the first time you use the machine

The laser training class is pay-what-you-can, and the recommended minimum donation is $20.

== Basic Safety ==
The laser cutter is generally a very safe machine to use. However, as with all industrial machines, you need to treat it with respect. The main safety concerns are creating fires, hurting your eyes or skin, getting crushed by the machine, and creating toxic fumes.

The basics:
* ALWAYS MONITOR THE LASER BEAM CUTTING YOUR WORK!
* DO NOT STARE DIRECTLY BECAUSE BURN-GENERATED VISIBLE LIGHT IS VERY BRIGHT!
* USE YOUR PERIPHERAL VISION!
* OPEN THE LID if you see a fire
* BLOW IT OUT if the fire keeps burning
* DON'T CUT UNAPPROVED MATERIALS!
* MAKE SURE THE WINDOWS BY THE BATHROOM ARE CLOSED SO YOU DON'T FUMIGATE NOISEBRIDGE

=== Fire ===

[[Image:Laser_water_estop.jpg|thumb|right|upright=3|alt=Laser cutter with water and estop| The water squirt bottle is sitting on top of the laser, and the estop is the round red button.]]

You can really hurt yourself or burn the building down with this machine. If you follow the safety rules, the chances of you causing this is close to zero. Some materials are very flammable on the laser cutter, and shouldn't be cut. Never cut an unapproved material, or a material you can't identify. A laser beam can also initiate a fire if the speed of the cut is too slow or the laser power is set too high.

Ways to not cause fires:
* ALWAYS MONITOR THE LASER CUTTER WHENEVER IT IS CUTTING AS FIRES CAN HAPPEN. The laser affects your material by heating it. Your job can change in seconds with the accumulation of heat in your material. Never leave the room while the laser is in operation. If you leave the laser unattended, your access to the laser cutter will be permanently revoked.
* Use reasonable speed/power settings. Start with the recommended speed/power settings for your material. Be patient - resist the temptation to crank the power and speed to rush through your job. This can cause fires.
** There will be some light when material is cut. This light at the point of lasing may be ok as long as it stays with the motion of the laser. If a flame appears while the laser is in operation, stop your job and try again with lower heat settings.
* Know where the fire extinguisher is in case of a fire. The ONLY fire extinguisher that should be used on the laser cutter is the halotron extinguisher right next to the laser cutter. Other fire extinguishers are corrosive and will ruin the machine.

How to put out a fire:
* Push the estop. (To turn the machine back on after the estop was hit, you need to switch the power switch on the right hand side of the machine off and on again).
* Open the lid.
* If it's small, try and blow it out.
* If it's smallish, try and squirt it out with the water squirt bottle sitting on the right hand side of the machine.
* If that doesn't work, use the halotron fire extinguisher to the right of the laser cutter. Aim it at the base of the flame.

=== Damage to eyes and skin ===
The laser beam can instantly and permanently blind you. It can also burn your skin.
* The lid's window will block the infrared laser beam, but it doesn't block the visible light produced by the burn. THE VISIBLE LIGHT CAN BE BRIGHT ENOUGH TO DAMAGE YOUR RETINA! DO NOT STARE DIRECTLY AT THE CUT! Use your peripheral vision.
* You don't ever want any part of your body in contact with the beam.
* As long as the door is closed, you're safe to look at the laser. There are interlocks on the door that help ensure the laser never operates with the doors open. Don't disable them.

=== Crushing danger ===

The laser cutter is a dumb machine. It doesn't care whether your hand is in the way when it's moving. The head can move when the door is open. Always make sure everyone's hands are out of the machine before moving the head.

Also be very careful not to crash the head into other parts of the machine. Be very careful when moving the z-axis to not crash the head into the bed, and to not move the z-axis if the focus length acrylic circle is under the lens.

If you need something to weigh down your material, use the magnetic balls or beanbags that are kept near the laser; nothing else. Do not let the laser head crash into these; if it does immediately stop the job.

Be *very* careful to not put the beanbags (or any other material) in such a situation where they may be dragged by the head. The head should never bump into anything, and *especially* never drag anything.

=== Fumes ===
The laser cutter burns the things it's cutting, which can create toxic fumes.
* ONLY CUT APPROVED MATERIALS. Cutting nonapproved materials can release really toxic gases, including chlorine and cyanide. These are really bad for humans, as well as being very damaging to the laser cutter.
* The ventilation fan should always be running if the laser cutter is on, even if it's not cutting. It's currently wired such that you can't turn on the laser cutter without the fan turning on, but please make sure it's running.

== Care of the machine ==

'''Please don't perform any maintenance on the machine (including cleaning lenses/mirrors or aligning mirrors) unless you've specifically trained on it.'''

The laser cutter is finely calibrated piece of machinery. Please close the lid gently, and do not push or jar the machine at any time. Do not lean or press on the tray - it's fragile, and needs to be perfectly flat for the laser cutter to cut properly. If you take the honeycomb bed or slats out, please be ULTRA CAREFUL with them - put them somewhere where they won't get damaged or warped.

== Paying for your laser time ==

The laser cutter has parts that wear out over time, which can be quite costly to replace, especially the laser tube. A new tube costs several thousand dollars. Thus, we require people to pay for the time on the laser they use, so we can pay for new parts. The cost for using the laser cutter is $5 per hour of cutting time.

To figure out how much time your job takes, press the File button, select your file, and then select Work Time from the menu. It will tell you in hours:minutes.seconds.

There is a laser cutter donation box on the wall of the Sparkle Forge room. Please pay for the cutting time you actually use, even if you end up running your job multiple times.

== Workflows ==

=== Overall Workflow ===

This is the overall structure of the workflow. Each part is elaborated below.

# Laser start up
# Material setup
# Convert file to DXF
# Load file onto the machine
# Dry run
# Cut/Engrave
# Laser shut down
# Cleanup

=== Laser start up ===

[[Image:Laser_chiller.jpg|thumb|right|upright=3|alt=Laser chiller| The laser chiller is the box on the bottom left of this photograph. If the laser doesn't beep when it turns on, you should turn on the chiller manually.]]

# Turn on power and ensure that the fan and chiller are running. If you do not hear beeps when the laser starts up, the chiller is not running and you must turn it on.
# Move the head as far forward and right as possible, close to the controls

=== Material setup ===

# Clean the bed of any scraps that may be on it
# Move the cut head as far forward and right as possible (near the controls)
# Raise the laser head as far up as possible
# Raise the bed to the desired height, watching the laser head to avoid crashes
# Move the laser head as far back and right as possible
# Place material on the bed
# Focus the laser (do at least for each distinct thickness, optimally do for each piece of material)

=== Focusing the laser ===

[[Image:Laser_shelf.jpg|thumb|right|upright=3|alt=Shelf by laser cutter | This is the shelf to the left of the laser cutter. The acrylic disks used for focusing the laser are in the toolbox with the yellow lid.]]

Noisebridge has acryllic disks cut to various thicknesses that can be used to accurately focus the laser. Specifically the laser head needs to be locked to 8mm above the surface of the material you're cutting.

# Place the material on the cut bed
# Move the cut head to the center of the area to cut, watching the laser head to avoid crashes w/ material
## Note that the honeycomb bed can move up and down (Z-axis) so if the material doesn't fit under, hit Z/U on the laser controls and navigate the menu until Z axis (or something similar) is selected. Then use the left and right arrows to move the bed up and down.
# Loosen the wing nut and raise the head all the way up
# Place the focusing discs on the material under the head
# Lower the head until it just touches the focusing disc (8mm above material)
# '''When you focus the laser, ALWAYS make sure the metal adaptor for the air hose is facing straight towards you'''
# Lock the head in place (tighten the wing nut)
# Remove the focusing discs

=== Convert an image in Inkscape to a DXF file ===

# Load the image into Inkscape
# Set the different cut paths to different colors (for controlling settings, etc.)
# Perform any debugging steps (by default you should perform all of them b/c of errors in the laser software)
# Save as a DXF. Be sure to make the units be millimeters so that importing later will correctly scale the image.

=== Debugging DXF Problems ===

Sometimes exporting to DXF introduces bizarre extra lines. There are two things to try to debug. The first is to convert objects to paths:

# Select all the problematic shapes
# Path > Object to Path

If this fails to resolve the issue, you can try a more radical solution which will eliminate all bezier paths entirely:

# Select all the problematic shapes
# Convert bezier paths to lines (Extensions > Modify Path > Flatten Bezier).

Flatness 0.5 is good to start with. Smaller = better approximation of the curves. A lower flatness number takes more time to compute, but also produces a better approximation to the curve. Be sure to ungroup (sometimes multiple times) before trying this, as grouped objects cannot be flattened as a group. This is especially important for text which is by default a group (each character being a separate object in Inkscape once you've turned it into a path).

Sometimes need to select the path's directly with the path tool (but not the points!).

Also see http://www.pstoedit.net/ for conversion from svg to dxf files.

=== Loading into the laser cutter software ===

# Import the file with File > Import
# Resize as needed, tho if the file was exported w/ millimeter units, the software should also import the image with the correct size.
# Set the cut order:
##* EITHER Set the cut order to inside-out (Handle > Cut optimize > Inside to outside)
##* OR Manually specify cut order with the Set cut property tool (Edit > Set cutting property). See below for more details.
# Set the speed and power for the layers as necessary, and the process mode for each layer to either cut (for continuous line cutting) or dot (for dashed line cutting) or scan (for engraving)
# Optionally, simulate the cutting/engraving process.
# Download to the machine (Laser Work panel on the bottom right).

=== Manually specifying cut order ===

In the Set cutting property window (Edit > Set cutting property), you can manually re-order the cut paths. In the window, you'll see an image of the workpiece, and to its right, two lists of paths. When you first open the window, all of the cut paths are in the left. If you select a path (either in the image or in the list) and click the button labeled ">>", this path will be transferred to the end of the right list of paths. If you click ">>>", all of the paths in the left list will be moved to the end of the right list (preserving order). Similarly, clicking "<<<" will move the right list to the end of the left list. If you select a cut path in the right list, the up and down arrow buttons will reorder that path in the chosen direction.

=== Loading speed and power settings from library ===

# In the top right panel, double click the layer of interest
# Click "Load parameters from library"
# Select the library item
# Click "Load"

=== Saving power and speed settings to library ===

# In the top right panel, double click the layer of interest
# Make sure the layer is set to the desired parameters
# Click "Load parameters from library"
# Click "Save as"
# Enter a name and optionally some notes
# Click "Ok"

=== Simulation ===

# Open the simulation window with either Edit > Preview or the toolbar button labelled with a monitor.
# Click the Simulation button in the right panel

=== Cutting ===

# Select the file to use using the File button
# Move the head to the initial guess origin with the arrow buttons
# Test the frame with the Frame button adjust origin as necessary
# Set the origin by pressing Origin
# Test the cut by turning the laser power off and pressing the Start/Pause button
# Turn the laser power on
# Cut by pressing the Start/Pause button
# It is generally a good idea to put the laser head into one of the top corners and resetting origin before opening the laser if you plan on adding new material to avoid collisions with a moving head.

=== Engraving ===

In the laser software, open the layers you wish to engrave in the layer parameters panel, and send the processing mode to "Scan". This will do a raster scan of the region bounded by the paths in that layer. An even-odd rule is used to assign regions to the "inside" vs "outside" of the engraving.

=== Cancel a cut/dry run ===

# Pause with the Start/Pause button
# Cancel and move back to the origin with the Esc button

=== Laser shut down ===

# Move the head as far forward and right as possible (near the controls)
# Raise the laser head as far up as possible
# Set origin with the origin button (this helps avoid the laser swinging across the bed later)
# Let the fan run for a little bit (~30 seconds)
# Turn the power off

=== Cleanup ===

[[Image:Laser_tray.jpg|thumb|right|upright=3|alt=Laser bottom tray| This is the bottom tray of the laser, which should be cleaned out after use.]]

# Remove pieces of material scrap left on the bed
# Open the tray door on the front bottom and empty the scraps left there

=== Calculating work time ===

On the computer:

* Open the simulation window (see above). Total work time and time of laser use are displayed in the top right. Donations should be calculated by laser use, not total work time.

On the machine:

* Whole file: File > Select file > Right Arrow > Work Time > Enter
* Current run: Pause the cut, then check time at the bottom right

== Fusion 360 ==
Fusion 360 is a free CAD (Computer Aided Design) program from Autodesk for designing 3D parts, and arguably the best one currently available. If you're designing something complex on the laser cutter, particularly with multiple parts that need to fit together, I highly recommend it over drawing programs like Inkscape. It also has CAM (Computer Aided Manufacturing) capabilities, which makes it very useful for CNC machining and laser cutting. There's a copy of the software on the laser cutter computer, and you can download it [http://www.autodesk.com/products/fusion-360/overview here]. It's free as long as you make less than $100k per year using it.

=== Workflow 1: The Quick and Dirty Way ===
This is the fastest way, and works a lot of the time
# Make sure your sketch only contains straight lines, arcs, and circles, and no spline curves. If your sketch has splines, go to [[#Workflow 3: The Long Way]]
# Make sure your part is designed using a single sketch, and that you want to cut all the lines in that sketch. If not, go to [[#Workflow 2: The Middle Ground]]
# Right click on your sketch and click Save As DXF
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]

=== Workflow 2: The Middle Ground ===
If you're not sure, this is probably where you should start.
# Make sure your sketch only contains straight lines, arcs, and circles, and no spline curves. If your sketch has splines, go to [[#Workflow 3: The Long Way]]
# Right click on the top surface of the part you want to cut, and click Create Sketch
# Hit the P key to open the Project dialog box, then select the top surface of your part, and any other lines you want to cut
# Hit OK, then remove any lines you don't want cut
# Open the Sketches folder near the top of the tree, then right click your new sketch and click Save As DXF
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]

=== Workflow 3: The Long Way ===
This allows more complicated things like exporting splines, which doesn't work with the above methods, kerf compensation, which makes your parts fit together snugly, but you can also use the above methods and then do it in RDWorks, or lead-ins and lead-outs, which can make for a cleaner cut, but I can't figure out how to get RDWorks to import correctly.
# Design a part to be laser cut by drawing a 2D sketch and extruding it
# Go to the CAM workspace by clicking the Model button in the top left, then selecting CAM
# Select the Waterjet operation (if you don't see this, turn it on under Preferences -> Preview)
## Set Type to Laser Cutting
## Select the Cutting Mode, either Through - Auto or Etch
## Look up the kerf of the material you're cutting in the [[#Known good materials]] section, and enter that in Kerf Width, or if your material's not listed, cut one a [http://www.thingiverse.com/thing:1166680 kerf gauge] and put the result in the wiki. The kerf changes depending on the thickness, speed and power. Setting a larger kerf width will make your parts fit tighter, and setting a smaller kerf will make them looser.
## Select the contours of your part that you want to cut
## Go to the Passes tab, and change Compensation Type to In Computer
## Hit OK to close the dialog box, and you can see a preview of your tool path. You can go back to edit it by double clicking the contour operation in the tree on the left
# To export to DXF, click the Post Process button, which says G1 G2. Make sure rdworkslaser is selected as your post processor, type a name for the export and hit Post. Then select the folder to put it in.
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]
# Fusion automatically orders the cuts from inside out and in the fastest order, but RDWorks doesn't always respect that order, so you may need to optimize the cut order again

=== Advanced Options ===
# If you're using your own computer for the first time and not the laser cutter desktop, you have to enable the laser cutter support which is still in beta, by clicking on your name in the top right, then Preferences, Preview, and checking "CAM - Waterjet/Laser/Plasma cutter support". You will also need to download the custom post processor that we use for this laser.
# There's a simulate button to the left of the Post Process button, if you want to do it in Fusion
# If you want to disable or tweak the lead ins and lead outs, you can go to the Linking tab. Lead ins and lead outs can fix the bump you get on the side of your part where the laser started and stopped, but they also make extra cuts in your scrap material, which you may want to keep. In this tab you can also specify the Entry Position for each cut path.
# You can disable Kerf Compensation by settting Sideways Compensation to Center under the Passes tab, though this is not recommended

== Techniques ==

=== Kerf Compensation ===

For any given layer, you can compensate for the kerf (width of the cut) by opening it's settings and clicking the "Advance" button next to the "Seal" input box towards the middle-bottom. Enable sew compensation, and pick the direction and sew width (kerf size). The inward direction will make the actual cut move toward the inside of a closed cut path, outward will move it towards the outside.

In general, for cuts on the outside, you want to move outward, to move the actual cut edge be exactly where the path is in your design. For cuts on the inside, you want to use the inward direction.

=== Negative Space Engraving ===

You can engrave a vector shape with a hole in the middle of it, so that you get enclosed portions that are not engraved in the middle of fully engraved portions. To do this, when you construct the image in your editor of choice, simply perform subtraction between the relevant paths, to remove the inner part. In the RDWorks laser software, the two paths will show up, and be independently editable (making them look like just two distinct paths to engrave), but they will engrave correctly as a negative space. Obviously test this w/ your software; this technique is known to work using Inkscape.

=== Nest & Waste Less Material ===

As of 01/2018 you can use the industrial strength [http://deepnest.io/#quickstart Deepnest] installed on the [[Kaitian_CM1309|Laser Cutter computer]] + [[CollaborationStation|Collaboration Station]] in Hackitorium. We have an unlimited subscription available to laser users, which is compatible with both ''DXF'', ''Corel CDR'' and ''SVG'' formats. Please ask if you need login credentials. Also available from the same author for free is [http://svgnest.com/| SVGNest, which can be used by clicking here].

=== Text Cutting ===

In Inkscape, after converting the text object to a path, it's necessary to ungroup the text as well, to create separate paths, prior to flattening the bezier curves.

If you're using a cursive font and want everything to be one piece, convert the text object to a path, and use Path > Union. This tool in general is quite useful for merging paths that have been independently drawn but need to be merged into a single path. For example, if you made two overlapping circles, without this the cutter would just cut the two circles, which leads to a lemon-shaped piece in the center. If you union the paths, it will cut an outline as well. Path > Union will not make any holes in the figure go away, it only gets rid of cuts passing through area covered by another shape.

Engraved text requires no other special technique because no cuts are made, but text cutting is non-trivial. Because of loops, it's sometimes desirable to use a stencil font, especially at smaller scales where legibility is important. 1001 Fonts has a number of stencil fonts for free. At 10pt, some good fonts are Marsh, Spacedock, and Allerta.

== Troubleshooting ==

=== File doesn't appear in laser cutter after successful download ===
If the laser cutter has 99 files loaded into it, new files will not show up. To fix this, open up RDWorks8, and on the right side, select the Doc tab. Inside that tab, click Read to read all the files in the laser cutter, and then click Delete all.
[[Image:laser_cutter_read_files.png|thumb|right|upright=3|alt=read files | This is the button used to read stored files from the laser cutter.]] [[Image:laser_cutter_delete_all_files.png|thumb|right|upright=3|alt=delete all files | This is the button used to delete all stored files from the laser cutter to make room for new ones.]]

== Maintenance==

'''Please don't perform any maintenance on the machine (including cleaning lenses/mirrors or aligning mirrors) unless you've specifically trained on it.'''

== Chlorine material test ==

Before you cut any new material you *must* check that it is safe to cut; specifically that it will not produce chlorine gas when it is burned by the cutting laser. Chlorine is extremely dangerous in its gaseous form and so must be avoided at all costs.

To test a new material, you'll need a sample of the material, a small copper rod (about the thickness of a coat hanger), a pliars, and a handheld propane torch. We'll test for the presence of chlorine by burning a sample of the material in a high temperature propane flame and observe the visible emission spectra. Chrlorine produces a bright green light when burned, and so will be very obvious when you're testing your material.

First, turn on the ventilation on the Sparkle Forge. The switch for this is under the sign that says "For Non-Laser Fires Only", and above the non-laser fire extinguisher. Then, light the propane torch and set it to rest upright on a stable surface. Taking the pliar, hold the piece of copper in the blue part of the flame to heat it. As the copper begins to heat sufficiently it'll cause the flame to turn an orange color. A consistent orange color means that the copper has no residue material on its surface and so is clean enough to use as a test. If you observe non-orange flames when you burn the copper you may need to clean in further, either by waiting for the excess material to burn off, or by scrubbing the surface of the copper when it has cooled.

Once the copper is burning, take the hot copper and melt a sample of the new material onto it. For example if you were testing a new form of plastic you can roll the hot copper rod on the material, melting some of it onto the copper rod's surface.

With this done, place the copper rod back into the blue part of the flame. Observe the colors of the emission spectra from the new material burning. If you observe a bright green color, then the material contains chlorine and thus *must not* be burned further. Ventilate your surrounding area to avoid breathing it in. If you observe no green color as you burn your material sample, then the material is likely safe to use with the laser cutter.

Here is a video example by Zach in NYCResistor with a known good and known bad material: https://www.youtube.com/watch?v=D0_4NLmeSTI

== BANNED MATERIALS (NEVER USE THESE) ==

These materials '''must not be used in the laser cutter'''.

! colspan="10" bgcolor="#ccc" | Bad materials
|-
! Material
! Notes
|-
| PVC || Contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| Vinyl || Most contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| PVC Foams || Most contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| Foam Core || Usually made with PVC which is harmful as listed above.
|-
| Styrofoam || Can cause flash fires
|-
| Polycarbonate or PETG || Does not cut. TAP plastics sells both this and acrylic. '''Be sure to read your labels when purchasing material'''. Lexan is the trade name for Polycarbonate, while Plexiglass is the trade name for acrylic.
|-
| ABS || Gives off hydrogen cyanide which can kill you and also may damage the laser optics.
|-
| Fiberglass || Contains complex epoxies which will cause fires, chlorine, and cyanide. Also contains glass which will not cut.
|-
| Metals || Cannot be etched by this type of laser. Also is harmful as the reflective surface may cause the laser to be reflected back up to the head, damaging it. If someone claims to be etching metal using this type of laser then they are etching a metal with a plastic coating, anodized surface, or some other etchable surface on top.

Yes, this is now possible as of 01/2018.

# Double check you made a folder inside ''\My Documents\PUT YOUR FILES HERE (IN YOUR OWN FOLDER)\''
# Ping @James on Slack with the name of your folder.
# Be sure to mention if you need a password added to your folder.
# Wait a day for the share link to be activated and sent to you.

== Troubleshooting ==

=== Help! All the menu options turned to gibberish! ===
The RDWorks software can be buggy. Go to the top menu, the right-most or or 2nd-right-most tab will have a Language option. Select English.
When that happens, the bed size settings might also have changed. Double check Config -> Document Settings (?). The proper settings are 1300mm × 900mm.
(TODO: need to double check the exact menu labels, doing this from memory at the moment)

=== SOLIDWORKS ===
Apparently DXFs exported from Solidworks (at least v 2017) break when directly imported into RDWorks. The workaround is to import the DXF into Inkscape and re-export it from there.

| [[File:Andrew86_1.jpeg|200px|thumb|left|Andrew]] [[File:Andrew86_2.jpeg|200px|thumb|left|Andrew]]
| Andrew was behaving extremely erratically, with delusions and hallucinations about those around him. He accused one person of trying to reprogram him, made multiple racially charged comments towards others, would not leave people alone when asked, and often could not perceive their words when they were speaking to him because of his hallucinations about what they were saying to him. He also tore up the anti-harassment policy and was extremely difficult to remove from the space because of his inability to recognize what was being asked of him, and because of all the stuff he had accumulated around him physically.

|-
| Jason
| [[File:Jason.jpg|200px|thumb|left|Jason]]
| After being very helpful and friendly at Noisebridge for several months, others became very concerned and uncomfortable with his growing talk of conspiracies against him at Noisebridge, with hints of violence targeted at those he felt were part of the conspiracy. His erratic behavior and the above threats of violence resulted in Jason being asked to leave Noisebridge at the end of September, 2016.
|-
| Lance
| [[File:lance_combined.png|200px|thumb|left|Lance]]
| Lance was formally banned from Noisebridge in September 2016, although he has previously been asked repeatedly to leave and not come back. He refuses to leave the space peacefully and always requires significant effort to get him to to leave Noisebridge. He is a textbook tweaker, who while peaceful in his interactions with people, mutters threats under his breath.

*Note: He repeatedly tries to come back to the space, even when asked not to return (Once in April 2016, and twice in August/September 2016). He tried to enter again in October 2017. If asked to leave, he is not dangerous, although he is quite vocal.
|-
| Mark Janssen (Xer0Dynamite)
| [[File:Mark_janssen.jpg|200px|thumb|left|Mark Janssen]]
| Mark was banned from Noisebridge due to a history of internet hate speech and having been asked to leave Sudo Room. Noisebridge aims to be a space that is inclusive of people of all walks of life, which means we actively work to exclude those with views of intolerance and threats of violence.

|-
|Diana
|[[File:Diana_ban_photo.jpg|200px|thumb|left|Diana in June-2016]]
|Diana was banned at Sudo Room in June-2016 for physical violence against a member. Since Diana was banned for safe space reasons, they are automatically also banned from Noisebridge. 
According to an email from Sudo Room: "This was an escalation of a dispute between two people who had an existing relationship and Diana lives very close to sudo room so you shouldn't worry overly about a problem at other hackerspaces." And from the Sudo Room "Asked to Leave" page, Diana "Additionally has been using the space as their living room (playing WoW all day) and caught sleeping at least twice."
|-
|David/Bunny
|[[File:David_Bunny2.jpg|200px|thumb|left|Bunny in March 2016]]

|-
|Adam
|[[File:Adam.jpg|200px|thumb|left|Adam in December 2015]]
|Asked to leave having been caught stealing from others in the space.

At several points misused the space in the creation of his "art", hiding large amounts of "art" around the space.

|Matt the tweaker
|[[File:mattthetweaker.jpg|200px|thumb|left|Matt the tweaker]]
|Matt carries a backpack full of shower rings twisted with tangle therapy tangles. He has converted his brain into a computer and is using it to solve the tangles with an algorithm. He is quiet and not aggressive, but very fixated on his tangles and can't form a completed thought, continuing on until you interrupt him.

Persistently tell Matt that "you have to leave now" and walk him out. He will go about 5 feet at a time but is not aggressive.

|This guy went into the back classroom and took Rayc's wallet out of his backpack. Rayc saw him with the wallet in his hand and the guy tried to say it was his. He then started running towards the door and was tackled by Jake. We made him show us that nothing was in his pockets, and he kept avoiding the big pocket in the front of his jacket. This pocket turned out to have Sasha's smart phone. During the search his crack pipe fell onto the floor and broke into many pieces. We let him go and told him not to come back.

For more information on Nyle, see [[85]]. Nyle has been spending a whole lot of time at the space recently - perhaps half his days. He never hacks anything and makes no secret of the fact that he never will. Jesse Z and Alan asked him to not come back repeatedly (February - March '12). If he does come back, please escort him out and tell him that he can explain himself at a Tuesday meeting if he would like to.

[[file:Jon-2.png|200px|thumb|right|Jon]]
|Jonathan was asked not to come back, due to allegations of organizing illegal activities from within Noisebridge and theft. A few days later, he had a proxy return to the space a few days later on his behalf to retrieve blankets, etc. that he'd apparently stashed in the darkroom. However, what his proxy took was apparently not the blankets that he wanted, and he shortly thereafter came upstairs and went into the darkroom, himself leaving with items that appeared to be bedsheets. The fabric his associate had taken was found in a heap at the bottom of the elevator and returned to the darkroom. Several days later, Jonathan returned to Noisebridge with his hand shoved in a gym bag, claiming he had a gun. He continued pushing past people to get into the main space, screaming constantly about killing everyone and then himself, and that everyone was to leave, or he would kill them all. He also claimed that the cops were hot on his trail and would arrive at Noisebridge at any moment, and that he intended to provoke a [http://en.wikipedia.org/wiki/Suicide_by_cop suicide-by-cop]. Not sure on whether or not he did have a gun, people were not taking a chance as they filed for the exit. However, Derek, Jedi, Rayc, Ben, stayed behind, calling him on his bullshit. Four people swarmed him as he made a b-line sprint for the fire escape. They wrestled him to the floor and removed his bags away from him. Jedi arm barred and escorted Jonathan down the stairs to the sidewalk, bringing him over to the quickly-amassing phalanx of squad cars. Immediate consensus was that he is not welcome in the space again.

|Ilya
|[[file:Ilya.jpg|200px|thumb|left|Ilya]]
|This person named Ilya was behaving irrationally, and confused his own backpack with Patricks, causing suspicion that he was intending to steal things. He also put on Patricks' clothes and said he thought people were allowed to use whatever items were in the space. He had some small, and not particularly valuable, items that he had pocketed, and had stashed random, not valuable, items in the bathroom. He was unable to explain his behavior to Dr. J and was handed over to police, who did not take him into custody, and he was told not to return to Noisebridge.

He was with his brother Alex who did not do anything sketchy and should not be banned. -jake

|Older guy with longish gray hair, who has often come to Noisebridge with bedding, and has used Noisebridge as a home from time to time. He has been asked to leave, and not come back. He has come back anyway. He has a gate key -- if you see him, demand that he give you the key.

Here is a link to the meeting where Harvey was banned: 
[[Meeting_Notes_2013_09_10#Proposals_discussed_this_week]] 
And here is the relevant quote: 
:"Harvey is no longer allowed in the space. Has admitted to stealing, was caught sleeping in the stairwell on many occassions, returned items that belonged to multiple residents of Noisebridge. Was seen and accounted for by multiple members of Noisebridge to be digging in other people's belongings. Many tools and properties of Noisebridge were found among Harvey's things."

On 24th September 2014 Harvey attacked Mitch while trying to interfere with the contents of the mailbox. "If you see Harvey ever again, call the police. He bit my thumb tonight to get back the piece of mail he was taking from our mailbox."

It became difficult to trust him. He wore people out in endless discussions with the repeated claim there was some kind of class conspiracy going on within the community.

|Very abusive to people in the space.
In late 2014, after being denied access to the space for being super drunk (with PirateMatt), rather than go away, he popped the top door hinges to gain access.
Though often very nice, and helpful, he was asked to stay away from Noisebridge for his abusive and erratic behaviors.
He was banned at Sudo Room for safe space reasons after being abusive there.
He's now reciprocally banned from Noisebridge for safe space reasons.

| [[File:Andrew86_1.jpeg|200px|thumb|left|Andrew]] [[File:Andrew86_2.jpeg|200px|thumb|left|Andrew]]
| Andrew was behaving extremely erratically, with delusions and hallucinations about those around him. He accused one person of trying to reprogram him, made multiple racially charged comments towards others, would not leave people alone when asked, and often could not perceive their words when they were speaking to him because of his hallucinations about what they were saying to him. He also tore up the anti-harassment policy and was extremely difficult to remove from the space because of his inability to recognize what was being asked of him, and because of all the stuff he had accumulated around him physically.

|-
| Jason
| [[File:Jason.jpg|200px|thumb|left|Jason]]
| After being very helpful and friendly at Noisebridge for several months, others became very concerned and uncomfortable with his growing talk of conspiracies against him at Noisebridge, with hints of violence targeted at those he felt were part of the conspiracy. His erratic behavior and the above threats of violence resulted in Jason being asked to leave Noisebridge at the end of September, 2016.
|-
| Lance
| [[File:lance_combined.png|200px|thumb|left|Lance]]
| Lance was formally banned from Noisebridge in September 2016, although he has previously been asked repeatedly to leave and not come back. He refuses to leave the space peacefully and always requires significant effort to get him to to leave Noisebridge. He is a textbook tweaker, who while peaceful in his interactions with people, mutters threats under his breath.

*Note: He repeatedly tries to come back to the space, even when asked not to return (Once in April 2016, and twice in August/September 2016). He tried to enter again in October 2017. If asked to leave, he is not dangerous, although he is quite vocal.
|-
| Mark Janssen (Xer0Dynamite)
| [[File:Mark_janssen.jpg|200px|thumb|left|Mark Janssen]]
| Mark was banned from Noisebridge due to a history of internet hate speech and having been asked to leave Sudo Room. Noisebridge aims to be a space that is inclusive of people of all walks of life, which means we actively work to exclude those with views of intolerance and threats of violence.

|-
|Diana
|[[File:Diana_ban_photo.jpg|200px|thumb|left|Diana in June-2016]]
|Diana was banned at Sudo Room in June-2016 for physical violence against a member. Since Diana was banned for safe space reasons, they are automatically also banned from Noisebridge. 
According to an email from Sudo Room: "This was an escalation of a dispute between two people who had an existing relationship and Diana lives very close to sudo room so you shouldn't worry overly about a problem at other hackerspaces." And from the Sudo Room "Asked to Leave" page, Diana "Additionally has been using the space as their living room (playing WoW all day) and caught sleeping at least twice."
|-
|David/Bunny

|-
|Adam
|[[File:Adam.jpg|200px|thumb|left|Adam in December 2015]]
|Asked to leave having been caught stealing from others in the space.

At several points misused the space in the creation of his "art", hiding large amounts of "art" around the space.

Was caught sleeping in the elevator overnight in late November 2015.

|Matt the tweaker
|[[File:mattthetweaker.jpg|200px|thumb|left|Matt the tweaker]]
|Matt carries a backpack full of shower rings twisted with tangle therapy tangles. He has converted his brain into a computer and is using it to solve the tangles with an algorithm. He is quiet and not aggressive, but very fixated on his tangles and can't form a completed thought, continuing on until you interrupt him.

Persistently tell Matt that "you have to leave now" and walk him out. He will go about 5 feet at a time but is not aggressive.

|This guy went into the back classroom and took Rayc's wallet out of his backpack. Rayc saw him with the wallet in his hand and the guy tried to say it was his. He then started running towards the door and was tackled by Jake. We made him show us that nothing was in his pockets, and he kept avoiding the big pocket in the front of his jacket. This pocket turned out to have Sasha's smart phone. During the search his crack pipe fell onto the floor and broke into many pieces. We let him go and told him not to come back.

For more information on Nyle, see [[85]]. Nyle has been spending a whole lot of time at the space recently - perhaps half his days. He never hacks anything and makes no secret of the fact that he never will. Jesse Z and Alan asked him to not come back repeatedly (February - March '12). If he does come back, please escort him out and tell him that he can explain himself at a Tuesday meeting if he would like to.

[[file:Jon-2.png|200px|thumb|right|Jon]]
|Jonathan was asked not to come back, due to allegations of organizing illegal activities from within Noisebridge and theft. A few days later, he had a proxy return to the space a few days later on his behalf to retrieve blankets, etc. that he'd apparently stashed in the darkroom. However, what his proxy took was apparently not the blankets that he wanted, and he shortly thereafter came upstairs and went into the darkroom, himself leaving with items that appeared to be bedsheets. The fabric his associate had taken was found in a heap at the bottom of the elevator and returned to the darkroom. Several days later, Jonathan returned to Noisebridge with his hand shoved in a gym bag, claiming he had a gun. He continued pushing past people to get into the main space, screaming constantly about killing everyone and then himself, and that everyone was to leave, or he would kill them all. He also claimed that the cops were hot on his trail and would arrive at Noisebridge at any moment, and that he intended to provoke a [http://en.wikipedia.org/wiki/Suicide_by_cop suicide-by-cop]. Not sure on whether or not he did have a gun, people were not taking a chance as they filed for the exit. However, Derek, Jedi, Rayc, Ben, stayed behind, calling him on his bullshit. Four people swarmed him as he made a b-line sprint for the fire escape. They wrestled him to the floor and removed his bags away from him. Jedi arm barred and escorted Jonathan down the stairs to the sidewalk, bringing him over to the quickly-amassing phalanx of squad cars. Immediate consensus was that he is not welcome in the space again.

|Ilya
|[[file:Ilya.jpg|200px|thumb|left|Ilya]]
|This person named Ilya was behaving irrationally, and confused his own backpack with Patricks, causing suspicion that he was intending to steal things. He also put on Patricks' clothes and said he thought people were allowed to use whatever items were in the space. He had some small, and not particularly valuable, items that he had pocketed, and had stashed random, not valuable, items in the bathroom. He was unable to explain his behavior to Dr. J and was handed over to police, who did not take him into custody, and he was told not to return to Noisebridge.

He was with his brother Alex who did not do anything sketchy and should not be banned. -jake

|Older guy with longish gray hair, who has often come to Noisebridge with bedding, and has used Noisebridge as a home from time to time. He has been asked to leave, and not come back. He has come back anyway. He has a gate key -- if you see him, demand that he give you the key.

Here is a link to the meeting where Harvey was banned: 
[[Meeting_Notes_2013_09_10#Proposals_discussed_this_week]] 
And here is the relevant quote: 
:"Harvey is no longer allowed in the space. Has admitted to stealing, was caught sleeping in the stairwell on many occassions, returned items that belonged to multiple residents of Noisebridge. Was seen and accounted for by multiple members of Noisebridge to be digging in other people's belongings. Many tools and properties of Noisebridge were found among Harvey's things."

On 24th September 2014 Harvey attacked Mitch while trying to interfere with the contents of the mailbox. "If you see Harvey ever again, call the police. He bit my thumb tonight to get back the piece of mail he was taking from our mailbox." If you call the SFPD in relation to Harvey cite the case number 140-810-381 in relation to his assaulting Mitch.

It became difficult to trust him. He wore people out in endless discussions with the repeated claim there was some kind of class conspiracy going on within the community.

| Egon (aka 86me)
|[[File:Egon.jpg|200px|thumb|left|Egon]]
|Very abusive to people in the space.
In late 2014, after being denied access to the space for being super drunk (with PirateMatt), rather than go away, he popped the top door hinges to gain access.
Though often very nice, and helpful, he was asked to stay away from Noisebridge for his abusive and erratic behaviors.
He was banned at Sudo Room for safe space reasons after being abusive there.
He's now reciprocally banned from Noisebridge for safe space reasons.

Hosting an Event

2018-09-14T21:22:38Z

Mcscope: /* General Guidelines */

==Overview==
We're happy to host teaching and co-operative events at Noisebridge. There's no charge, though please consult and respect the many others working in the space. Here are some suggested guidelines for hosting an event at Noisebridge, whether its a short workshop, a regular hackathon, or a bigger unconference-style event. Noisebridge is also a nonprofit member of [https://communityspace.withgoogle.com/|the Google.org community space], which may be able to host events that are too large for our physical space or call for a more corporate vibe.

==Our Physical Space==
===Event-Hosting Areas===
Noisebridge has three primary areas within our physical space for hosting an event, consisting of two classrooms (Turing and Church) and a large open conference area (the Hackitorium).

===Accessibility===
Please visit our [[Accessibility]] page for a full description of how Noisebridge makes our physical space accessible to everybody.

Temporary access code for the gate can be set up for your participants.

==Google.org's Community Space==
Reach out to secretary@noisebridge.net or treasurer@noisebridge.net to ask if it's an event Noisebridge would be comfortable being associated with. If you get a confirmation from someone on those mailing lists, you can put in an [https://communityspace.withgoogle.com/request-event/|event request with Google.org].

==General Guidelines==
====Get members/philanthropists involved====
'''You don't have to be a member to start an event.''' It's recommended to involve at least one Noisebridge member/philanthropist as part of your planning to avoid common pitfalls when working with Noisebridge. Ask around the space for a member, or ask on the discuss [[mailinglist]].

====Communicate the event to the group====
'''Publicize the event to the users of Noisebridge''' via the 8PM Tuesday meeting, this [[Category:Events|wiki]], the [[mailinglist|Noisebridge discussion and announcement mailing lists]], and the [[IRC|Noisebridge IRC channel]], with enough lead time that the community can respond and give feedback. See also, [[Mailinglist/Announce_guidelines]] for help on writing a good announcement mail! Also put the event on our [https://www.meetup.com/noisebridge/events/ Meetup Page] - send a message and ask to become an event organizer to do so.

Be aware of the existing ongoing events and try to work around them, even if they're not in your part of the space. Some events like 5MOF and work in the shop can be noisy! Also events might be happening that aren't listed anywhere that may create annoying room scheduling issues.

====Setup and clean up====

'''Leave the space cleaner than you found it.''' Have a plan for setting up the space and have a plan for cleaning up after yourself (and follow it). Someone should arrive about an hour before the event to straighten out the space, clean it, troubleshoot AV, etc. At the end of the event or class, ask people who participated to help clean up the space used. We build our own reality

"Use our tools - Mindfully" Events can use any tools/spaces at Noisebridge that are for general use. However, if you're going to be using a tool, please make sure you know how to use it safely, and not break it. Please help your participants to do the same.

====Donations and fees====
'''Consider asking participants for a monetary donation to Noisebridge during your event.''' We have a recommended [[Preamble | one minute preamble]] for event organizers to say at the beginning of their meetings. It explains how we work, and how your visitors can help keep Noisebridge going.

Noisebridge prides itself in being an open space to all that are excellent. '''Please keep in mind that we generally don't host classes or events that have a participation or class fee.''' Charging for materials or kits is acceptable (such as buying a blinking LED kit to work on during [[Circuit Hacking Mondays]]), but shouldn't be required to join in the class or event.

====No age restrictions====
'''Noisebridge is an all ages space''', if your class or event has an age requirement, please bring it up at a Tuesday meeting or on our discussion mailing list before proceeding.

==Event Listing==
After taking all of the above into consideration, and feeling like Noisebridge is the right spot for your event, listing it on our events page would be great! Here are some steps to do so...

# Create an individual page for your event. Include contact info for the organizer(s), date/time, location (if at Noisebridge, where in the space), and a pretty good description of what the event is. The important bit is contact info, helps when we're cleaning up the events list.
# Include the code <tt><nowiki>[[Category:Events]]</nowiki></tt> at the bottom of the page.
# Go to the [[:Category:Events|Events]] page and add in your event to the correct spot. We use 24 hour time.
# The events listed on our [[Noisebridge|Main Page]] are actually pulled from the [[:Category:Events|Events]] page. So no need to add it again.
# If you have an event that happens once, or a reoccurring event that doesn't occur anymore, please remove it from the [[:Category:Events|Events]] page after you're done.

==Mitch's suggestion on how to do an event at Noisebridge==
We don't have a formal procedure for scheduling at Noisebridge.

But here's how I suggest doing it:
* First, take a look at the info on this page (above), where there's a bunch of good info.
* Look on the [[Noisebridge|Noisebridge]] website, and near the top, check out the '''Events and Classes''' section (both ''Upcoming Events'' and ''Recurring Events''), and find a time where Noisebridge can accommodate the crowd you're expecting.
* Send an email to the '''Noisebridge-Discussion''' list, and let folks know that you want to give your event. and when, and ask if there's interest, and ask if there is any conflict of space/time. (You'll need to subscribe: [[Mailinglist|Mailing List page]] -- but please know there are trolls there -- please do not feed the trolls.)
* If you get any positive feedback, then there that is indication enough that there people will show up (way more than give you feedback on the email list).
* Create a wiki page for your event on the Noisebridge website (which is entirely a wiki).
* Add the event to the ''Upcoming Events'' section, including the link to your event wiki page. Then post to the '''Noisebridge-Announce''' list (you'll need to subscribe -- [[Mailinglist|Maling List page]] -- and someone will approve your post -- this is the ''only'' thing at Noisebridge which is moderated).
* Publicize the hell out of the event to let people know it's happening!
* One week before, post to both the Discussion and Announce lists. And then you can post to both lists again the day before to remind people (and to catch last-minute stragglers).

==Procedural Checklist for Larger / More Impactful Events==

Some events are bigger than others.

If you are expecting more than (say) 20 people at your event, you may find the [[ProceduralEventChecklist|Procedural Event Checklist]] useful for thinking through mundane but important aspects of planning such as managing the cultural impact of the event on [[Noisebridge|Noisebridge]] at large and making sure there's enough toilet paper in the bathrooms.

Check out the [[ProceduralEventChecklist|Procedural Event Checklist page]]. (And don't get too overwhelmed; while quite long, it's meant to *help* you plan aspects of your butt that you may not have thought of.)

* Look on the [[Noisebridge|Noisebridge]] website, and near the top, check out the '''Events and Classes''' section (both ''Upcoming Events'' and ''Recurring Events''), and find a time where Noisebridge can accommodate the crowd you're expecting.
* Send an email to the '''Noisebridge-Discussion''' list, and let folks know that you want to give your event. and when, and ask if there's interest, and ask if there is any conflict of space/time. (You'll need to subscribe: [[Mailinglist|Mailing List page]] -- but please know there are trolls there -- please do not feed the trolls.)
* If you get any positive feedback, then there that is indication enough that there people will show up (way more than give you feedback on the email list).
* Create a wiki page for your event on the Noisebridge website (which is entirely a wiki).
* Add the event to the ''Upcoming Events'' section, including the link to your event wiki page. Then post to the '''Noisebridge-Announce''' list (you'll need to subscribe -- [[Mailinglist|Maling List page]] -- and someone will approve your post -- this is the ''only'' thing at Noisebridge which is moderated).
* Publicize the hell out of the event to let people know it's happening!
* One week before, post to both the Discussion and Announce lists. And then you can post to both lists again the day before to remind people (and to catch last-minute stragglers).

==Procedural Checklist for Larger / More Impactful Events==

Some events are bigger than others.

If you are expecting more than (say) 20 people at your event, you may find the [[ProceduralEventChecklist|Procedural Event Checklist]] useful for thinking through mundane but important aspects of planning such as managing the cultural impact of the event on [[Noisebridge|Noisebridge]] at large and making sure there's enough toilet paper in the bathrooms.

Check out the [[ProceduralEventChecklist|Procedural Event Checklist page]]. (And don't get too overwhelmed; while quite long, it's meant to *help* you plan aspects of your butt that you may not have thought of.)

Hosting an Event

2018-09-14T21:19:04Z

Mcscope: /* General Guidelines */

==Overview==
We're happy to host teaching and co-operative events at Noisebridge. There's no charge, though please consult and respect the many others working in the space. Here are some suggested guidelines for hosting an event at Noisebridge, whether its a short workshop, a regular hackathon, or a bigger unconference-style event. Noisebridge is also a nonprofit member of [https://communityspace.withgoogle.com/|the Google.org community space], which may be able to host events that are too large for our physical space or call for a more corporate vibe.

==Our Physical Space==
===Event-Hosting Areas===
Noisebridge has three primary areas within our physical space for hosting an event, consisting of two classrooms (Turing and Church) and a large open conference area (the Hackitorium).

===Accessibility===
Please visit our [[Accessibility]] page for a full description of how Noisebridge makes our physical space accessible to everybody.

Temporary access code for the gate can be set up for your participants.

==Google.org's Community Space==
Reach out to secretary@noisebridge.net or treasurer@noisebridge.net to ask if it's an event Noisebridge would be comfortable being associated with. If you get a confirmation from someone on those mailing lists, you can put in an [https://communityspace.withgoogle.com/request-event/|event request with Google.org].

==General Guidelines==
====Get members/philanthropists involved====
'''You don't have to be a member to start an event.''' It's recommended to involve at least one Noisebridge member/philanthropist as part of your planning to avoid common pitfalls when working with Noisebridge. Ask around the space for a member, or ask on the discuss [[mailinglist]].

====Communicate the event to the group====
'''Publicize the event to the users of Noisebridge''' via the 8PM Tuesday meeting, this [[Category:Events|wiki]], the [[mailinglist|Noisebridge discussion and announcement mailing lists]], and the [[IRC|Noisebridge IRC channel]], with enough lead time that the community can respond and give feedback. See also, [[Mailinglist/Announce_guidelines]] for help on writing a good announcement mail!

Be aware of the existing ongoing events and try to work around them, even if they're not in your part of the space. Some events like 5MOF and work in the shop can be noisy! Also events might be happening that aren't listed anywhere that may create annoying room scheduling issues.

====Setup and clean up====

'''Leave the space cleaner than you found it.''' Have a plan for setting up the space and have a plan for cleaning up after yourself (and follow it). Novice tip: At the end of the event or class, ask people who participated to help clean up the space used.

"Use our tools - Mindfully" Events can use any tools/spaces at Noisebridge that are for general use. However, if you're going to be using a tool, please make sure you know how to use it safely, and not break it. Please help your participants to do the same.

====Donations and fees====
'''Consider asking participants for a monetary donation to Noisebridge during your event.''' We have a recommended [[Preamble | one minute preamble]] for event organizers to say at the beginning of their meetings. It explains how we work, and how your visitors can help keep Noisebridge going.

Noisebridge prides itself in being an open space to all that are excellent. '''Please keep in mind that we generally don't host classes or events that have a participation or class fee.''' Charging for materials or kits is acceptable (such as buying a blinking LED kit to work on during [[Circuit Hacking Mondays]]), but shouldn't be required to join in the class or event.

====No age restrictions====
'''Noisebridge is an all ages space''', if your class or event has an age requirement, please bring it up at a Tuesday meeting or on our discussion mailing list before proceeding.

==Event Listing==
After taking all of the above into consideration, and feeling like Noisebridge is the right spot for your event, listing it on our events page would be great! Here are some steps to do so...

# Create an individual page for your event. Include contact info for the organizer(s), date/time, location (if at Noisebridge, where in the space), and a pretty good description of what the event is. The important bit is contact info, helps when we're cleaning up the events list.
# Include the code <tt><nowiki>[[Category:Events]]</nowiki></tt> at the bottom of the page.
# Go to the [[:Category:Events|Events]] page and add in your event to the correct spot. We use 24 hour time.
# The events listed on our [[Noisebridge|Main Page]] are actually pulled from the [[:Category:Events|Events]] page. So no need to add it again.
# If you have an event that happens once, or a reoccurring event that doesn't occur anymore, please remove it from the [[:Category:Events|Events]] page after you're done.

==Mitch's suggestion on how to do an event at Noisebridge==
We don't have a formal procedure for scheduling at Noisebridge.

But here's how I suggest doing it:
* First, take a look at the info on this page (above), where there's a bunch of good info.
* Look on the [[Noisebridge|Noisebridge]] website, and near the top, check out the '''Events and Classes''' section (both ''Upcoming Events'' and ''Recurring Events''), and find a time where Noisebridge can accommodate the crowd you're expecting.

Best of all, Noisebridge is about people getting together at the space in San Francisco to do stuff. DO pay attention, as some eventSs just arise organically from the bottom up!

'''Want to host your event at Noisebridge?''' We like seeing classes and talks on interesting things pertaining to various subjects of hacking. Most of all, we like seeing familiar faces. Please participate in the space and our [[Meetings|weekly Tuesday meetings]] to see if we're the right audience for what you want to share before announcing a new event. Additionally, please see our [[Hosting an Event|events hosting page]] for suggestions on how to use Noisebridge for your event/class/workshop.

|title = HackTheLeft
|description = [[HackTheLeft|Hack the Left]] is an ''anticapitalist'' hackathon, going on for the entire long weekend of February 5th-7th at Noisebridge. This is an experiment to see what happens when you get a bunch of leftists in a room for a weekend with the intention to advance liberatory and ''anticapitalist'' projects using technology. This includes software projects like Tor and Signal, art projects like the Anti-Eviction Mapping Project and Men in Grey, hardware projects like mesh networks and signal jammers, and tools for rad organizations like Anti Police-Crimethink Project and Food Not Bombs. It's clear that there's a huge amount of opportunity for liberatory technology. It's up to us to build it. 

*Hackathon participants should be able to get into Noisebridge by [[Hours | its 11:00 AM opening hour]], if not earlier, for both weekend days.

Noisebridge grew out of Chaos Communications Camp in August, 2007. We have had regular weekly Tuesday meetings since September 2007. We rented our first physical space on September 1st 2008, which we quickly outgrew, and have been at our much larger 5,200 square-foot second location since September 1st 2009. Noisebridge was granted [[Incorporation|tax-exempt 501(c)(3) status]] in July 2009, retroactive to October 2008.

'''Friday, August 3, 19:00 - 21:00 [http://feedbackrobotics.com| Feedback Robotics Meetup]''' at Noisebridge Hackitorium. Come for robotic show and tell. The organizer is bringing Arduino controlled autonomous sumo robots. Bring a laptop with the Arduino IDE to participate in the tournament.

'''Saturday, August 4, 10:00 and Sunday August 5, 10:00 - [[cleaning|NOISEBRIDGE CLEANING DAYS]]''' Please come help give our space the good cleaning it needs. Please note we will be reclaiming and purging materials and projects. Details at [[cleaning]].

'''Thursday August 9th, from 6pm - 8pm''' -- '''DIY Mate Making Workshop''' Mate is the main fuel that most hacker spaces and congresses run on and we would like to take it out of the bottle and offer everyone the chance to try a real mate in traditional style. Facilitating communication and sharing, this workshop will infuse participants into a new dimension loaded with theobromine, antioxidents, and caffeine produced in an autonomous way from the forests. The basic preparation techniques and rules will be explained and participants are welcome to drink together, try their hand at making one and see what other herbs can be mixed into the mate. Or just come and sit separately and enjoy the Mate .

Visiting CA for the first time from Berlin, Fabricio, from Meta Mate is a mate hacker on a mission to fuel the community with an option of mates. An increasing number of mate drinkers wanting to cut down on the sugar consumption turn to us when looking for DIY mate solutions. We support open techonoloogy transfers with our autonomous sustainable open source. Long before the internet existed, the Guarani Indians used to sit around the fire and exchange information while sharing a mate, the drink fostered positive creative envisioning....Centuries later we sit around computers and share information over bottles of mate....we encourage you to put the bottles and electronics aside and enjoy a moment with a mate.

Current Consensus Items

2018-08-01T03:57:57Z

Mcscope:

This is a page for hosting consensus items currently under debate, with their formal wording.

Is your consensus item still drafty, in need of much revision, and not something that you think people already can more or less agree with? Perhaps it belongs on the [[Draft Consensus Items]] page, instead?

The [[Consensus_Items_History|Consensus Items History]] is the public record of consensus items that have been decided on in the past. Please move the records from the "Current" page to the "History" page once they've been approved/blocked.

| NB Should Get a Credit Card
| Because Noisebridge is applying for a mortgage in the nearish future, and b/c we have basically no credit history, Noisebridge would benefit from having a credit card to build credit history. It would also make various reimbursement and purchase processes smoother. Therefore, Noisebridge will acquire a credit card, and precisely which one will be determined by little-c consensus. The treasurer shall be responsible for the final signup process.

| Discretionary fund
|Noisebridge shall establish a Discretionary Fund in order to reimburse people for small purchases that help the space.

Guidelines for the discretionary fund

* Spend it like it's your own money (as judiciously as you would spend your own money)
* On things that the space needs to be clean, organized, smoothly operating, safe, etc

Examples of things that would be appropriate for the discretionary fund:
* toilet paper,
* broom,
* shelves/drawers,
* exterminator
* new bulb for projector,
* low-cost useful tools,
* reasonable consumables

Examples of things that may not be appropriate:

* Brand new pieces of machinery that cost several hundred dollars
* Items to support an individual person project

Since this inherently involves judgement calls, there should be a discretionary fund working group that shall use little-c consensus to decide if a given expense should be reimbursed.

The discretionary fund shall start with a value of 1000$ immediately. After we spend that and get a sense of the likely monthly budget, we can make a consensus item to fill it up every month

== How to get trained to use the laser cutter ==

# Ask a trainer if they will train you
# Schedule a time with the trainer
## The laser training class size is limited to 5 students, so that everyone can see how to operate the laser.
# Get trained
# Get your name on the list of users before the first time you use the machine

The laser training class is pay-what-you-can, and the recommended minimum donation is $20.

== Basic Safety ==
The laser cutter is generally a very safe machine to use. However, as with all industrial machines, you need to treat it with respect. The main safety concerns are creating fires, hurting your eyes or skin, getting crushed by the machine, and creating toxic fumes.

The basics:
* ALWAYS MONITOR THE LASER BEAM CUTTING YOUR WORK!
* DO NOT STARE DIRECTLY BECAUSE BURN-GENERATED VISIBLE LIGHT IS VERY BRIGHT!
* USE YOUR PERIPHERAL VISION!
* OPEN THE LID if you see a fire
* BLOW IT OUT if the fire keeps burning
* DON'T CUT UNAPPROVED MATERIALS!
* MAKE SURE THE WINDOWS BY THE BATHROOM ARE CLOSED SO YOU DON'T FUMIGATE NOISEBRIDGE

=== Fire ===

[[Image:Laser_water_estop.jpg|thumb|right|upright=3|alt=Laser cutter with water and estop| The water squirt bottle is sitting on top of the laser, and the estop is the round red button.]]

You can really hurt yourself or burn the building down with this machine. If you follow the safety rules, the chances of you causing this is close to zero. Some materials are very flammable on the laser cutter, and shouldn't be cut. Never cut an unapproved material, or a material you can't identify. A laser beam can also initiate a fire if the speed of the cut is too slow or the laser power is set too high.

Ways to not cause fires:
* ALWAYS MONITOR THE LASER CUTTER WHENEVER IT IS CUTTING AS FIRES CAN HAPPEN. The laser affects your material by heating it. Your job can change in seconds with the accumulation of heat in your material. Never leave the room while the laser is in operation. If you leave the laser unattended, your access to the laser cutter will be permanently revoked.
* Use reasonable speed/power settings. Start with the recommended speed/power settings for your material. Be patient - resist the temptation to crank the power and speed to rush through your job. This can cause fires.
** There will be some light when material is cut. This light at the point of lasing may be ok as long as it stays with the motion of the laser. If a flame appears while the laser is in operation, stop your job and try again with lower heat settings.
* Know where the fire extinguisher is in case of a fire. The ONLY fire extinguisher that should be used on the laser cutter is the halotron extinguisher right next to the laser cutter. Other fire extinguishers are corrosive and will ruin the machine.

How to put out a fire:
* Push the estop. (To turn the machine back on after the estop was hit, you need to switch the power switch on the right hand side of the machine off and on again).
* Open the lid.
* If it's small, try and blow it out.
* If it's smallish, try and squirt it out with the water squirt bottle sitting on the right hand side of the machine.
* If that doesn't work, use the halotron fire extinguisher to the right of the laser cutter. Aim it at the base of the flame.

=== Damage to eyes and skin ===
The laser beam can instantly and permanently blind you. It can also burn your skin.
* The lid's window will block the infrared laser beam, but it doesn't block the visible light produced by the burn. THE VISIBLE LIGHT CAN BE BRIGHT ENOUGH TO DAMAGE YOUR RETINA! DO NOT STARE DIRECTLY AT THE CUT! Use your peripheral vision.
* You don't ever want any part of your body in contact with the beam.
* As long as the door is closed, you're safe to look at the laser. There are interlocks on the door that help ensure the laser never operates with the doors open. Don't disable them.

=== Crushing danger ===

The laser cutter is a dumb machine. It doesn't care whether your hand is in the way when it's moving. The head can move when the door is open. Always make sure everyone's hands are out of the machine before moving the head.

Also be very careful not to crash the head into other parts of the machine. Be very careful when moving the z-axis to not crash the head into the bed, and to not move the z-axis if the focus length acrylic circle is under the lens.

If you need something to weigh down your material, use the magnetic balls or beanbags that are kept near the laser; nothing else. Do not let the laser head crash into these; if it does immediately stop the job.

Be *very* careful to not put the beanbags (or any other material) in such a situation where they may be dragged by the head. The head should never bump into anything, and *especially* never drag anything.

=== Fumes ===
The laser cutter burns the things it's cutting, which can create toxic fumes.
* ONLY CUT APPROVED MATERIALS. Cutting nonapproved materials can release really toxic gases, including chlorine and cyanide. These are really bad for humans, as well as being very damaging to the laser cutter.
* The ventilation fan should always be running if the laser cutter is on, even if it's not cutting. It's currently wired such that you can't turn on the laser cutter without the fan turning on, but please make sure it's running.

== Care of the machine ==

'''Please don't perform any maintenance on the machine (including cleaning lenses/mirrors or aligning mirrors) unless you've specifically trained on it.'''

The laser cutter is finely calibrated piece of machinery. Please close the lid gently, and do not push or jar the machine at any time. Do not lean or press on the tray - it's fragile, and needs to be perfectly flat for the laser cutter to cut properly. If you take the honeycomb bed or slats out, please be ULTRA CAREFUL with them - put them somewhere where they won't get damaged or warped.

== Paying for your laser time ==

The laser cutter has parts that wear out over time, which can be quite costly to replace, especially the laser tube. A new tube costs several thousand dollars. Thus, we require people to pay for the time on the laser they use, so we can pay for new parts. The cost for using the laser cutter is $5 per hour of cutting time.

To figure out how much time your job takes, press the File button, select your file, and then select Work Time from the menu. It will tell you in hours:minutes.seconds.

There is a laser cutter donation box on the wall of the Sparkle Forge room. Please pay for the cutting time you actually use, even if you end up running your job multiple times.

== Workflows ==

=== Overall Workflow ===

This is the overall structure of the workflow. Each part is elaborated below.

# Laser start up
# Material setup
# Convert file to DXF
# Load file onto the machine
# Dry run
# Cut/Engrave
# Laser shut down
# Cleanup

=== Laser start up ===

[[Image:Laser_chiller.jpg|thumb|right|upright=3|alt=Laser chiller| The laser chiller is the box on the bottom left of this photograph. If the laser doesn't beep when it turns on, you should turn on the chiller manually.]]

# Turn on power and ensure that the fan and chiller are running. If you do not hear beeps when the laser starts up, the chiller is not running and you must turn it on.
# Move the head as far forward and right as possible, close to the controls

=== Material setup ===

# Clean the bed of any scraps that may be on it
# Move the cut head as far forward and right as possible (near the controls)
# Raise the laser head as far up as possible
# Raise the bed to the desired height, watching the laser head to avoid crashes
# Move the laser head as far back and right as possible
# Place material on the bed
# Focus the laser (do at least for each distinct thickness, optimally do for each piece of material)

=== Focusing the laser ===

[[Image:Laser_shelf.jpg|thumb|right|upright=3|alt=Shelf by laser cutter | This is the shelf to the left of the laser cutter. The acrylic disks used for focusing the laser are in the toolbox with the yellow lid.]]

Noisebridge has acryllic disks cut to various thicknesses that can be used to accurately focus the laser. Specifically the laser head needs to be locked to 8mm above the surface of the material you're cutting.

# Place the material on the cut bed
# Move the cut head to the center of the area to cut, watching the laser head to avoid crashes w/ material
## Note that the honeycomb bed can move up and down (Z-axis) so if the material doesn't fit under, hit Z/U on the laser controls and navigate the menu until Z axis (or something similar) is selected. Then use the left and right arrows to move the bed up and down.
# Loosen the wing nut and raise the head all the way up
# Place the focusing discs on the material under the head
# Lower the head until it just touches the focusing disc (8mm above material)
# Lock the head in place (tighten the wing nut)
# Remove the focusing discs

=== Convert an image in Inkscape to a DXF file ===

# Load the image into Inkscape
# Set the different cut paths to different colors (for controlling settings, etc.)
# Perform any debugging steps (by default you should perform all of them b/c of errors in the laser software)
# Save as a DXF. Be sure to make the units be millimeters so that importing later will correctly scale the image.

=== Debugging DXF Problems ===

Sometimes exporting to DXF introduces bizarre extra lines. There are two things to try to debug. The first is to convert objects to paths:

# Select all the problematic shapes
# Path > Object to Path

If this fails to resolve the issue, you can try a more radical solution which will eliminate all bezier paths entirely:

# Select all the problematic shapes
# Convert bezier paths to lines (Extensions > Modify Path > Flatten Bezier).

Flatness 0.5 is good to start with. Smaller = better approximation of the curves. A lower flatness number takes more time to compute, but also produces a better approximation to the curve. Be sure to ungroup (sometimes multiple times) before trying this, as grouped objects cannot be flattened as a group. This is especially important for text which is by default a group (each character being a separate object in Inkscape once you've turned it into a path).

Sometimes need to select the path's directly with the path tool (but not the points!).

Also see http://www.pstoedit.net/ for conversion from svg to dxf files.

=== Loading into the laser cutter software ===

# Import the file with File > Import
# Resize as needed, tho if the file was exported w/ millimeter units, the software should also import the image with the correct size.
# Set the cut order:
##* EITHER Set the cut order to inside-out (Handle > Cut optimize > Inside to outside)
##* OR Manually specify cut order with the Set cut property tool (Edit > Set cutting property). See below for more details.
# Set the speed and power for the layers as necessary, and the process mode for each layer to either cut (for continuous line cutting) or dot (for dashed line cutting) or scan (for engraving)
# Optionally, simulate the cutting/engraving process.
# Download to the machine (Laser Work panel on the bottom right).

=== Manually specifying cut order ===

In the Set cutting property window (Edit > Set cutting property), you can manually re-order the cut paths. In the window, you'll see an image of the workpiece, and to its right, two lists of paths. When you first open the window, all of the cut paths are in the left. If you select a path (either in the image or in the list) and click the button labeled ">>", this path will be transferred to the end of the right list of paths. If you click ">>>", all of the paths in the left list will be moved to the end of the right list (preserving order). Similarly, clicking "<<<" will move the right list to the end of the left list. If you select a cut path in the right list, the up and down arrow buttons will reorder that path in the chosen direction.

=== Loading speed and power settings from library ===

# In the top right panel, double click the layer of interest
# Click "Load parameters from library"
# Select the library item
# Click "Load"

=== Saving power and speed settings to library ===

# In the top right panel, double click the layer of interest
# Make sure the layer is set to the desired parameters
# Click "Load parameters from library"
# Click "Save as"
# Enter a name and optionally some notes
# Click "Ok"

=== Simulation ===

# Open the simulation window with either Edit > Preview or the toolbar button labelled with a monitor.
# Click the Simulation button in the right panel

=== Cutting ===

# Select the file to use using the File button
# Move the head to the initial guess origin with the arrow buttons
# Test the frame with the Frame button adjust origin as necessary
# Set the origin by pressing Origin
# Test the cut by turning the laser power off and pressing the Start/Pause button
# Turn the laser power on
# Cut by pressing the Start/Pause button
# It is generally a good idea to put the laser head into one of the top corners and resetting origin before opening the laser if you plan on adding new material to avoid collisions with a moving head.

=== Engraving ===

In the laser software, open the layers you wish to engrave in the layer parameters panel, and send the processing mode to "Scan". This will do a raster scan of the region bounded by the paths in that layer. An even-odd rule is used to assign regions to the "inside" vs "outside" of the engraving.

=== Cancel a cut/dry run ===

# Pause with the Start/Pause button
# Cancel and move back to the origin with the Esc button

=== Laser shut down ===

# Move the head as far forward and right as possible (near the controls)
# Raise the laser head as far up as possible
# Set origin with the origin button (this helps avoid the laser swinging across the bed later)
# Let the fan run for a little bit (~30 seconds)
# Turn the power off

=== Cleanup ===

[[Image:Laser_tray.jpg|thumb|right|upright=3|alt=Laser bottom tray| This is the bottom tray of the laser, which should be cleaned out after use.]]

# Remove pieces of material scrap left on the bed
# Open the tray door on the front bottom and empty the scraps left there

=== Calculating work time ===

On the computer:

* Open the simulation window (see above). Total work time and time of laser use are displayed in the top right. Donations should be calculated by laser use, not total work time.

On the machine:

* Whole file: File > Select file > Right Arrow > Work Time > Enter
* Current run: Pause the cut, then check time at the bottom right

== Fusion 360 ==
Fusion 360 is a free CAD (Computer Aided Design) program from Autodesk for designing 3D parts, and arguably the best one currently available. If you're designing something complex on the laser cutter, particularly with multiple parts that need to fit together, I highly recommend it over drawing programs like Inkscape. It also has CAM (Computer Aided Manufacturing) capabilities, which makes it very useful for CNC machining and laser cutting. There's a copy of the software on the laser cutter computer, and you can download it [http://www.autodesk.com/products/fusion-360/overview here]. It's free as long as you make less than $100k per year using it.

=== Workflow 1: The Quick and Dirty Way ===
This is the fastest way, and works a lot of the time
# Make sure your sketch only contains straight lines, arcs, and circles, and no spline curves. If your sketch has splines, go to [[#Workflow 3: The Long Way]]
# Make sure your part is designed using a single sketch, and that you want to cut all the lines in that sketch. If not, go to [[#Workflow 2: The Middle Ground]]
# Right click on your sketch and click Save As DXF
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]

=== Workflow 2: The Middle Ground ===
If you're not sure, this is probably where you should start.
# Make sure your sketch only contains straight lines, arcs, and circles, and no spline curves. If your sketch has splines, go to [[#Workflow 3: The Long Way]]
# Right click on the top surface of the part you want to cut, and click Create Sketch
# Hit the P key to open the Project dialog box, then select the top surface of your part, and any other lines you want to cut
# Hit OK, then remove any lines you don't want cut
# Open the Sketches folder near the top of the tree, then right click your new sketch and click Save As DXF
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]

=== Workflow 3: The Long Way ===
This allows more complicated things like exporting splines, which doesn't work with the above methods, kerf compensation, which makes your parts fit together snugly, but you can also use the above methods and then do it in RDWorks, or lead-ins and lead-outs, which can make for a cleaner cut, but I can't figure out how to get RDWorks to import correctly.
# Design a part to be laser cut by drawing a 2D sketch and extruding it
# Go to the CAM workspace by clicking the Model button in the top left, then selecting CAM
# Select the Waterjet operation (if you don't see this, turn it on under Preferences -> Preview)
## Set Type to Laser Cutting
## Select the Cutting Mode, either Through - Auto or Etch
## Look up the kerf of the material you're cutting in the [[#Known good materials]] section, and enter that in Kerf Width, or if your material's not listed, cut one a [http://www.thingiverse.com/thing:1166680 kerf gauge] and put the result in the wiki. The kerf changes depending on the thickness, speed and power. Setting a larger kerf width will make your parts fit tighter, and setting a smaller kerf will make them looser.
## Select the contours of your part that you want to cut
## Go to the Passes tab, and change Compensation Type to In Computer
## Hit OK to close the dialog box, and you can see a preview of your tool path. You can go back to edit it by double clicking the contour operation in the tree on the left
# To export to DXF, click the Post Process button, which says G1 G2. Make sure rdworkslaser is selected as your post processor, type a name for the export and hit Post. Then select the folder to put it in.
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]
# Fusion automatically orders the cuts from inside out and in the fastest order, but RDWorks doesn't always respect that order, so you may need to optimize the cut order again

=== Advanced Options ===
# If you're using your own computer for the first time and not the laser cutter desktop, you have to enable the laser cutter support which is still in beta, by clicking on your name in the top right, then Preferences, Preview, and checking "CAM - Waterjet/Laser/Plasma cutter support". You will also need to download the custom post processor that we use for this laser.
# There's a simulate button to the left of the Post Process button, if you want to do it in Fusion
# If you want to disable or tweak the lead ins and lead outs, you can go to the Linking tab. Lead ins and lead outs can fix the bump you get on the side of your part where the laser started and stopped, but they also make extra cuts in your scrap material, which you may want to keep. In this tab you can also specify the Entry Position for each cut path.
# You can disable Kerf Compensation by settting Sideways Compensation to Center under the Passes tab, though this is not recommended

== Techniques ==

=== Kerf Compensation ===

For any given layer, you can compensate for the kerf (width of the cut) by opening it's settings and clicking the "Advance" button next to the "Seal" input box towards the middle-bottom. Enable sew compensation, and pick the direction and sew width (kerf size). The inward direction will make the actual cut move toward the inside of a closed cut path, outward will move it towards the outside.

In general, for cuts on the outside, you want to move outward, to move the actual cut edge be exactly where the path is in your design. For cuts on the inside, you want to use the inward direction.

=== Negative Space Engraving ===

You can engrave a vector shape with a hole in the middle of it, so that you get enclosed portions that are not engraved in the middle of fully engraved portions. To do this, when you construct the image in your editor of choice, simply perform subtraction between the relevant paths, to remove the inner part. In the RDWorks laser software, the two paths will show up, and be independently editable (making them look like just two distinct paths to engrave), but they will engrave correctly as a negative space. Obviously test this w/ your software; this technique is known to work using Inkscape.

=== Nest & Waste Less Material ===

As of 01/2018 you can use the industrial strength [http://deepnest.io/#quickstart Deepnest] installed on the [[Kaitian_CM1309|Laser Cutter computer]] + [[CollaborationStation|Collaboration Station]] in Hackitorium. We have an unlimited subscription available to laser users, which is compatible with both ''DXF'', ''Corel CDR'' and ''SVG'' formats. Please ask if you need login credentials. Also available from the same author for free is [http://svgnest.com/| SVGNest, which can be used by clicking here].

=== Text Cutting ===

In Inkscape, after converting the text object to a path, it's necessary to ungroup the text as well, to create separate paths, prior to flattening the bezier curves.

If you're using a cursive font and want everything to be one piece, convert the text object to a path, and use Path > Union. This tool in general is quite useful for merging paths that have been independently drawn but need to be merged into a single path. For example, if you made two overlapping circles, without this the cutter would just cut the two circles, which leads to a lemon-shaped piece in the center. If you union the paths, it will cut an outline as well. Path > Union will not make any holes in the figure go away, it only gets rid of cuts passing through area covered by another shape.

Engraved text requires no other special technique because no cuts are made, but text cutting is non-trivial. Because of loops, it's sometimes desirable to use a stencil font, especially at smaller scales where legibility is important. 1001 Fonts has a number of stencil fonts for free. At 10pt, some good fonts are Marsh, Spacedock, and Allerta.

== Troubleshooting ==

=== File doesn't appear in laser cutter after successful download ===
If the laser cutter has 99 files loaded into it, new files will not show up. To fix this, open up RDWorks8, and on the right side, select the Doc tab. Inside that tab, click Read to read all the files in the laser cutter, and then click Delete all.
[[Image:laser_cutter_read_files.png|thumb|right|upright=3|alt=read files | This is the button used to read stored files from the laser cutter.]] [[Image:laser_cutter_delete_all_files.png|thumb|right|upright=3|alt=delete all files | This is the button used to delete all stored files from the laser cutter to make room for new ones.]]

== Chlorine material test ==

Before you cut any new material you *must* check that it is safe to cut; specifically that it will not produce chlorine gas when it is burned by the cutting laser. Chlorine is extremely dangerous in its gaseous form and so must be avoided at all costs.

To test a new material, you'll need a sample of the material, a small copper rod (about the thickness of a coat hanger), a pliars, and a handheld propane torch. We'll test for the presence of chlorine by burning a sample of the material in a high temperature propane flame and observe the visible emission spectra. Chrlorine produces a bright green light when burned, and so will be very obvious when you're testing your material.

First, turn on the ventilation on the Sparkle Forge. The switch for this is under the sign that says "For Non-Laser Fires Only", and above the non-laser fire extinguisher. Then, light the propane torch and set it to rest upright on a stable surface. Taking the pliar, hold the piece of copper in the blue part of the flame to heat it. As the copper begins to heat sufficiently it'll cause the flame to turn an orange color. A consistent orange color means that the copper has no residue material on its surface and so is clean enough to use as a test. If you observe non-orange flames when you burn the copper you may need to clean in further, either by waiting for the excess material to burn off, or by scrubbing the surface of the copper when it has cooled.

Once the copper is burning, take the hot copper and melt a sample of the new material onto it. For example if you were testing a new form of plastic you can roll the hot copper rod on the material, melting some of it onto the copper rod's surface.

With this done, place the copper rod back into the blue part of the flame. Observe the colors of the emission spectra from the new material burning. If you observe a bright green color, then the material contains chlorine and thus *must not* be burned further. Ventilate your surrounding area to avoid breathing it in. If you observe no green color as you burn your material sample, then the material is likely safe to use with the laser cutter.

Here is a video example by Zach in NYCResistor with a known good and known bad material: https://www.youtube.com/watch?v=D0_4NLmeSTI

== BANNED MATERIALS (NEVER USE THESE) ==

These materials '''must not be used in the laser cutter'''.

{|border="1" cellpadding="5" cellspacing="0"
|-
! colspan="10" bgcolor="#ccc" | Bad materials
|-
! Material
! Notes
|-
| PVC || Contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| Vinyl || Most contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| PVC Foams || Most contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| Foam Core || Usually made with PVC which is harmful as listed above.
|-
| Styrofoam || Can cause flash fires
|-
| Polycarbonate or PETG || Does not cut. TAP plastics sells both this and acrylic. '''Be sure to read your labels when purchasing material'''. Lexan is the trade name for Polycarbonate, while Plexiglass is the trade name for acrylic.
|-
| ABS || Gives off hydrogen cyanide which can kill you and also may damage the laser optics.
|-
| Fiberglass || Contains complex epoxies which will cause fires, chlorine, and cyanide. Also contains glass which will not cut.
|-
| Metals || Cannot be etched by this type of laser. Also is harmful as the reflective surface may cause the laser to be reflected back up to the head, damaging it. If someone claims to be etching metal using this type of laser then they are etching a metal with a plastic coating, anodized surface, or some other etchable surface on top.

== Known good materials ==

These materials are known to be ok for use with the laser cutter. The speed and power of the laser cutter will need to be set appropriately for the material and thickness in use. Below is a table showing the suggested settings when cutting or etching them.

| Acrylic (3mm) || 400 || 5 || 20 || 55 || 0.15mm || || || Engraving: Power setting 4 and 5 have little visible difference except some minor lightening at the beginnings of cuts at power 4. Power 3.5 produces very light engraving, almost non-existent, with no engraving at the beginnings of cuts. Above power 5, little difference is visible, but powdery soot becomes more prevalent. Power 5 seems to be the best setting to produce frosted effects. If you are engraving with the paper still on, you may want to go higher (do a test)

== Sourcing Material ==

In general, you can get stuff from Amazon, but you have to wait for shipping.

For plastics: [http://www.google.com/maps/place/TAP+Plastics/@37.7711648,-122.4207603,17z/data=!3m1!4b1!4m5!3m4!1s0x808f7e27351bb079:0x7e3610d7dc178b10!8m2!3d37.7711648!4d-122.4185663 Tap Plastics] is nearby Noisebridge, but is expensive, [http://eplastics.com eplastics] is cheaper but you need to wait for shipping, and [https://www.google.com/maps/place/Mr.+Plastics/@37.7091519,-122.1546962,17z/data=!3m1!4b1!4m5!3m4!1s0x808f8fe7938349a3:0xafcb2526326faccd!8m2!3d37.7091519!4d-122.1525022 Mr. Plastics] is cheapest but is in San Leandro.

For woods: [http://www.google.com/maps/place/Discount+Builders+Supply/@37.7704879,-122.4191311,15z/data=!4m2!3m1!1s0x0:0x3c0d6c6e25a89652?sa=X&ved=0ahUKEwjV87WU-JzOAhUI6WMKHSPABOUQ_BIIeTAK Discount Builder Supply] is nearby.

== How do I send files to the Laser computer over the internet? ==

Send your files directly to the laser cutter through this URL [https://cloud.disroot.org/s/bFv70wtK9xQuyp3], which is kindly hosted for us by [https://disroot.org/en| Disroot.org] via [https://nextcloud.com/| Nextcloud].

All files are uploaded directly to ''\My Documents\PUT YOUR FILES HERE (IN YOUR OWN FOLDER)\Uploads for Noisebridge Lasercutter\''

Please move any files you upload to your own folder asap.

== Ok, I created a folder for my laser cutter files, but can I access them over the internet? ==
Yes, this is now possible as of 01/2018.

# Double check you made a folder inside ''\My Documents\PUT YOUR FILES HERE (IN YOUR OWN FOLDER)\''
# Ping @James on Slack with the name of your folder.
# Be sure to mention if you need a password added to your folder.
# Wait a day for the share link to be activated and sent to you.

== Troubleshooting ==

=== Help! All the menu options turned to gibberish! ===
The RDWorks software can be buggy. Go to the top menu, the right-most or or 2nd-right-most tab will have a Language option. Select English.
When that happens, the bed size settings might also have changed. Double check Config -> Document Settings (?). The proper settings are 1300mm × 900mm.
(TODO: need to double check the exact menu labels, doing this from memory at the moment)

=== SOLIDWORKS ===
Apparently DXFs exported from Solidworks (at least v 2017) break when directly imported into RDWorks. The workaround is to import the DXF into Inkscape and re-export it from there.

== How to get trained to use the laser cutter ==

# Ask a trainer if they will train you
# Schedule a time with the trainer
## The laser training class size is limited to 5 students, so that everyone can see how to operate the laser.
# Get trained
# Get your name on the list of users before the first time you use the machine

The laser training class is pay-what-you-can, and the recommended minimum donation is $20.

== Basic Safety ==
The laser cutter is generally a very safe machine to use. However, as with all industrial machines, you need to treat it with respect. The main safety concerns are creating fires, hurting your eyes or skin, getting crushed by the machine, and creating toxic fumes.

The basics:
* ALWAYS MONITOR THE LASER BEAM CUTTING YOUR WORK!
* DO NOT STARE DIRECTLY BECAUSE BURN-GENERATED VISIBLE LIGHT IS VERY BRIGHT!
* USE YOUR PERIPHERAL VISION!
* OPEN THE LID if you see a fire
* BLOW IT OUT if the fire keeps burning
* DON'T CUT UNAPPROVED MATERIALS!
* MAKE SURE THE WINDOWS BY THE BATHROOM ARE CLOSED SO YOU DON'T FUMIGATE NOISEBRIDGE

=== Fire ===

[[Image:Laser_water_estop.jpg|thumb|right|upright=3|alt=Laser cutter with water and estop| The water squirt bottle is sitting on top of the laser, and the estop is the round red button.]]

You can really hurt yourself or burn the building down with this machine. If you follow the safety rules, the chances of you causing this is close to zero. Some materials are very flammable on the laser cutter, and shouldn't be cut. Never cut an unapproved material, or a material you can't identify. A laser beam can also initiate a fire if the speed of the cut is too slow or the laser power is set too high.

Ways to not cause fires:
* ALWAYS MONITOR THE LASER CUTTER WHENEVER IT IS CUTTING AS FIRES CAN HAPPEN. The laser affects your material by heating it. Your job can change in seconds with the accumulation of heat in your material. Never leave the room while the laser is in operation. If you leave the laser unattended, your access to the laser cutter will be permanently revoked.
* Use reasonable speed/power settings. Start with the recommended speed/power settings for your material. Be patient - resist the temptation to crank the power and speed to rush through your job. This can cause fires.
** There will be some light when material is cut. This light at the point of lasing may be ok as long as it stays with the motion of the laser. If a flame appears while the laser is in operation, stop your job and try again with lower heat settings.
* Know where the fire extinguisher is in case of a fire. The ONLY fire extinguisher that should be used on the laser cutter is the halotron extinguisher right next to the laser cutter. Other fire extinguishers are corrosive and will ruin the machine.

How to put out a fire:
* Push the estop. (To turn the machine back on after the estop was hit, you need to switch the power switch on the right hand side of the machine off and on again).
* Open the lid.
* If it's small, try and blow it out.
* If it's smallish, try and squirt it out with the water squirt bottle sitting on the right hand side of the machine.
* If that doesn't work, use the halotron fire extinguisher to the right of the laser cutter. Aim it at the base of the flame.

=== Damage to eyes and skin ===
The laser beam can instantly and permanently blind you. It can also burn your skin.
* The lid's window will block the infrared laser beam, but it doesn't block the visible light produced by the burn. THE VISIBLE LIGHT CAN BE BRIGHT ENOUGH TO DAMAGE YOUR RETINA! DO NOT STARE DIRECTLY AT THE CUT! Use your peripheral vision.
* You don't ever want any part of your body in contact with the beam.
* As long as the door is closed, you're safe to look at the laser. There are interlocks on the door that help ensure the laser never operates with the doors open. Don't disable them.

=== Crushing danger ===

The laser cutter is a dumb machine. It doesn't care whether your hand is in the way when it's moving. The head can move when the door is open. Always make sure everyone's hands are out of the machine before moving the head.

Also be very careful not to crash the head into other parts of the machine. Be very careful when moving the z-axis to not crash the head into the bed, and to not move the z-axis if the focus length acrylic circle is under the lens.

If you need something to weigh down your material, use the magnetic balls or beanbags that are kept near the laser; nothing else. Do not let the laser head crash into these; if it does immediately stop the job.

Be *very* careful to not put the beanbags (or any other material) in such a situation where they may be dragged by the head. The head should never bump into anything, and *especially* never drag anything.

=== Fumes ===
The laser cutter burns the things it's cutting, which can create toxic fumes.
* ONLY CUT APPROVED MATERIALS. Cutting nonapproved materials can release really toxic gases, including chlorine and cyanide. These are really bad for humans, as well as being very damaging to the laser cutter.
* The ventilation fan should always be running if the laser cutter is on, even if it's not cutting. It's currently wired such that you can't turn on the laser cutter without the fan turning on, but please make sure it's running.

== Care of the machine ==

'''Please don't perform any maintenance on the machine (including cleaning lenses/mirrors or aligning mirrors) unless you've specifically trained on it.'''

The laser cutter is finely calibrated piece of machinery. Please close the lid gently, and do not push or jar the machine at any time. Do not lean or press on the tray - it's fragile, and needs to be perfectly flat for the laser cutter to cut properly. If you take the honeycomb bed or slats out, please be ULTRA CAREFUL with them - put them somewhere where they won't get damaged or warped.

== Paying for your laser time ==

The laser cutter has parts that wear out over time, which can be quite costly to replace, especially the laser tube. A new tube costs several thousand dollars. Thus, we require people to pay for the time on the laser they use, so we can pay for new parts. The cost for using the laser cutter is $5 per hour of cutting time.

To figure out how much time your job takes, press the File button, select your file, and then select Work Time from the menu. It will tell you in hours:minutes.seconds.

There is a laser cutter donation box on the wall of the Sparkle Forge room. Please pay for the cutting time you actually use, even if you end up running your job multiple times.

== Workflows ==

=== Overall Workflow ===

This is the overall structure of the workflow. Each part is elaborated below.

# Laser start up
# Material setup
# Convert file to DXF
# Load file onto the machine
# Dry run
# Cut/Engrave
# Laser shut down
# Cleanup

=== Laser start up ===

[[Image:Laser_chiller.jpg|thumb|right|upright=3|alt=Laser chiller| The laser chiller is the box on the bottom left of this photograph. If the laser doesn't beep when it turns on, you should turn on the chiller manually.]]

# Turn on power and ensure that the fan and chiller are running. If you do not hear beeps when the laser starts up, the chiller is not running and you must turn it on.
# Move the head as far forward and right as possible, close to the controls

=== Material setup ===

# Clean the bed of any scraps that may be on it
# Move the cut head as far forward and right as possible (near the controls)
# Raise the laser head as far up as possible
# Raise the bed to the desired height, watching the laser head to avoid crashes
# Move the laser head as far back and right as possible
# Place material on the bed
# Focus the laser (do at least for each distinct thickness, optimally do for each piece of material)

=== Focusing the laser ===

[[Image:Laser_shelf.jpg|thumb|right|upright=3|alt=Shelf by laser cutter | This is the shelf to the left of the laser cutter. The acrylic disks used for focusing the laser are in the toolbox with the yellow lid.]]

Noisebridge has acryllic disks cut to various thicknesses that can be used to accurately focus the laser. Specifically the laser head needs to be locked to 8mm above the surface of the material you're cutting.

# Place the material on the cut bed
# Move the cut head to the center of the area to cut, watching the laser head to avoid crashes w/ material
## Note that the honeycomb bed can move up and down (Z-axis) so if the material doesn't fit under, hit Z/U on the laser controls and navigate the menu until Z axis (or something similar) is selected. Then use the left and right arrows to move the bed up and down.
# Loosen the wing nut and raise the head all the way up
# Place the focusing discs on the material under the head
# Lower the head until it just touches the focusing disc (8mm above material)
# Lock the head in place (tighten the wing nut)
# Remove the focusing discs

=== Convert an image in Inkscape to a DXF file ===

# Load the image into Inkscape
# Set the different cut paths to different colors (for controlling settings, etc.)
# Perform any debugging steps (by default you should perform all of them b/c of errors in the laser software)
# Save as a DXF. Be sure to make the units be millimeters so that importing later will correctly scale the image.

=== Debugging DXF Problems ===

Sometimes exporting to DXF introduces bizarre extra lines. There are two things to try to debug. The first is to convert objects to paths:

# Select all the problematic shapes
# Path > Object to Path

If this fails to resolve the issue, you can try a more radical solution which will eliminate all bezier paths entirely:

# Select all the problematic shapes
# Convert bezier paths to lines (Extensions > Modify Path > Flatten Bezier).

Flatness 0.5 is good to start with. Smaller = better approximation of the curves. A lower flatness number takes more time to compute, but also produces a better approximation to the curve. Be sure to ungroup (sometimes multiple times) before trying this, as grouped objects cannot be flattened as a group. This is especially important for text which is by default a group (each character being a separate object in Inkscape once you've turned it into a path).

Sometimes need to select the path's directly with the path tool (but not the points!).

Also see http://www.pstoedit.net/ for conversion from svg to dxf files.

=== Loading into the laser cutter software ===

# Import the file with File > Import
# Resize as needed, tho if the file was exported w/ millimeter units, the software should also import the image with the correct size.
# Set the cut order:
##* EITHER Set the cut order to inside-out (Handle > Cut optimize > Inside to outside)
##* OR Manually specify cut order with the Set cut property tool (Edit > Set cutting property). See below for more details.
# Set the speed and power for the layers as necessary, and the process mode for each layer to either cut (for continuous line cutting) or dot (for dashed line cutting) or scan (for engraving)
# Optionally, simulate the cutting/engraving process.
# Download to the machine (Laser Work panel on the bottom right).

=== Manually specifying cut order ===

In the Set cutting property window (Edit > Set cutting property), you can manually re-order the cut paths. In the window, you'll see an image of the workpiece, and to its right, two lists of paths. When you first open the window, all of the cut paths are in the left. If you select a path (either in the image or in the list) and click the button labeled ">>", this path will be transferred to the end of the right list of paths. If you click ">>>", all of the paths in the left list will be moved to the end of the right list (preserving order). Similarly, clicking "<<<" will move the right list to the end of the left list. If you select a cut path in the right list, the up and down arrow buttons will reorder that path in the chosen direction.

=== Loading speed and power settings from library ===

# In the top right panel, double click the layer of interest
# Click "Load parameters from library"
# Select the library item
# Click "Load"

=== Saving power and speed settings to library ===

# In the top right panel, double click the layer of interest
# Make sure the layer is set to the desired parameters
# Click "Load parameters from library"
# Click "Save as"
# Enter a name and optionally some notes
# Click "Ok"

=== Simulation ===

# Open the simulation window with either Edit > Preview or the toolbar button labelled with a monitor.
# Click the Simulation button in the right panel

=== Cutting ===

# Select the file to use using the File button
# Move the head to the initial guess origin with the arrow buttons
# Test the frame with the Frame button adjust origin as necessary
# Set the origin by pressing Origin
# Test the cut by turning the laser power off and pressing the Start/Pause button
# Turn the laser power on
# Cut by pressing the Start/Pause button
# It is generally a good idea to put the laser head into one of the top corners and resetting origin before opening the laser if you plan on adding new material to avoid collisions with a moving head.

=== Engraving ===

In the laser software, open the layers you wish to engrave in the layer parameters panel, and send the processing mode to "Scan". This will do a raster scan of the region bounded by the paths in that layer. An even-odd rule is used to assign regions to the "inside" vs "outside" of the engraving.

=== Cancel a cut/dry run ===

# Pause with the Start/Pause button
# Cancel and move back to the origin with the Esc button

=== Laser shut down ===

# Move the head as far forward and right as possible (near the controls)
# Raise the laser head as far up as possible
# Set origin with the origin button (this helps avoid the laser swinging across the bed later)
# Let the fan run for a little bit (~30 seconds)
# Turn the power off

=== Cleanup ===

[[Image:Laser_tray.jpg|thumb|right|upright=3|alt=Laser bottom tray| This is the bottom tray of the laser, which should be cleaned out after use.]]

# Remove pieces of material scrap left on the bed
# Open the tray door on the front bottom and empty the scraps left there

=== Calculating work time ===

On the computer:

* Open the simulation window (see above). Total work time and time of laser use are displayed in the top right. Donations should be calculated by laser use, not total work time.

On the machine:

* Whole file: File > Select file > Right Arrow > Work Time > Enter
* Current run: Pause the cut, then check time at the bottom right

== Fusion 360 ==
Fusion 360 is a free CAD (Computer Aided Design) program from Autodesk for designing 3D parts, and arguably the best one currently available. If you're designing something complex on the laser cutter, particularly with multiple parts that need to fit together, I highly recommend it over drawing programs like Inkscape. It also has CAM (Computer Aided Manufacturing) capabilities, which makes it very useful for CNC machining and laser cutting. There's a copy of the software on the laser cutter computer, and you can download it [http://www.autodesk.com/products/fusion-360/overview here]. It's free as long as you make less than $100k per year using it.

=== Workflow 1: The Quick and Dirty Way ===
This is the fastest way, and works a lot of the time
# Make sure your sketch only contains straight lines, arcs, and circles, and no spline curves. If your sketch has splines, go to [[#Workflow 3: The Long Way]]
# Make sure your part is designed using a single sketch, and that you want to cut all the lines in that sketch. If not, go to [[#Workflow 2: The Middle Ground]]
# Right click on your sketch and click Save As DXF
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]

=== Workflow 2: The Middle Ground ===
If you're not sure, this is probably where you should start.
# Make sure your sketch only contains straight lines, arcs, and circles, and no spline curves. If your sketch has splines, go to [[#Workflow 3: The Long Way]]
# Right click on the top surface of the part you want to cut, and click Create Sketch
# Hit the P key to open the Project dialog box, then select the top surface of your part, and any other lines you want to cut
# Hit OK, then remove any lines you don't want cut
# Open the Sketches folder near the top of the tree, then right click your new sketch and click Save As DXF
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]

=== Workflow 3: The Long Way ===
This allows more complicated things like exporting splines, which doesn't work with the above methods, kerf compensation, which makes your parts fit together snugly, but you can also use the above methods and then do it in RDWorks, or lead-ins and lead-outs, which can make for a cleaner cut, but I can't figure out how to get RDWorks to import correctly.
# Design a part to be laser cut by drawing a 2D sketch and extruding it
# Go to the CAM workspace by clicking the Model button in the top left, then selecting CAM
# Select the Waterjet operation (if you don't see this, turn it on under Preferences -> Preview)
## Set Type to Laser Cutting
## Select the Cutting Mode, either Through - Auto or Etch
## Look up the kerf of the material you're cutting in the [[#Known good materials]] section, and enter that in Kerf Width, or if your material's not listed, cut one a [http://www.thingiverse.com/thing:1166680 kerf gauge] and put the result in the wiki. The kerf changes depending on the thickness, speed and power. Setting a larger kerf width will make your parts fit tighter, and setting a smaller kerf will make them looser.
## Select the contours of your part that you want to cut
## Go to the Passes tab, and change Compensation Type to In Computer
## Hit OK to close the dialog box, and you can see a preview of your tool path. You can go back to edit it by double clicking the contour operation in the tree on the left
# To export to DXF, click the Post Process button, which says G1 G2. Make sure rdworkslaser is selected as your post processor, type a name for the export and hit Post. Then select the folder to put it in.
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]
# Fusion automatically orders the cuts from inside out and in the fastest order, but RDWorks doesn't always respect that order, so you may need to optimize the cut order again

=== Advanced Options ===
# If you're using your own computer for the first time and not the laser cutter desktop, you have to enable the laser cutter support which is still in beta, by clicking on your name in the top right, then Preferences, Preview, and checking "CAM - Waterjet/Laser/Plasma cutter support". You will also need to download the custom post processor that we use for this laser.
# There's a simulate button to the left of the Post Process button, if you want to do it in Fusion
# If you want to disable or tweak the lead ins and lead outs, you can go to the Linking tab. Lead ins and lead outs can fix the bump you get on the side of your part where the laser started and stopped, but they also make extra cuts in your scrap material, which you may want to keep. In this tab you can also specify the Entry Position for each cut path.
# You can disable Kerf Compensation by settting Sideways Compensation to Center under the Passes tab, though this is not recommended

== Techniques ==

=== Kerf Compensation ===

For any given layer, you can compensate for the kerf (width of the cut) by opening it's settings and clicking the "Advance" button next to the "Seal" input box towards the middle-bottom. Enable sew compensation, and pick the direction and sew width (kerf size). The inward direction will make the actual cut move toward the inside of a closed cut path, outward will move it towards the outside.

In general, for cuts on the outside, you want to move outward, to move the actual cut edge be exactly where the path is in your design. For cuts on the inside, you want to use the inward direction.

=== Negative Space Engraving ===

You can engrave a vector shape with a hole in the middle of it, so that you get enclosed portions that are not engraved in the middle of fully engraved portions. To do this, when you construct the image in your editor of choice, simply perform subtraction between the relevant paths, to remove the inner part. In the RDWorks laser software, the two paths will show up, and be independently editable (making them look like just two distinct paths to engrave), but they will engrave correctly as a negative space. Obviously test this w/ your software; this technique is known to work using Inkscape.

=== Nest & Waste Less Material ===

As of 01/2018 you can use the industrial strength [http://deepnest.io/#quickstart Deepnest] installed on the [[Kaitian_CM1309|Laser Cutter computer]] + [[CollaborationStation|Collaboration Station]] in Hackitorium. We have an unlimited subscription available to laser users, which is compatible with both ''DXF'', ''Corel CDR'' and ''SVG'' formats. Please ask if you need login credentials. Also available from the same author for free is [http://svgnest.com/| SVGNest, which can be used by clicking here].

=== Text Cutting ===

In Inkscape, after converting the text object to a path, it's necessary to ungroup the text as well, to create separate paths, prior to flattening the bezier curves.

If you're using a cursive font and want everything to be one piece, convert the text object to a path, and use Path > Union. This tool in general is quite useful for merging paths that have been independently drawn but need to be merged into a single path. For example, if you made two overlapping circles, without this the cutter would just cut the two circles, which leads to a lemon-shaped piece in the center. If you union the paths, it will cut an outline as well. Path > Union will not make any holes in the figure go away, it only gets rid of cuts passing through area covered by another shape.

Engraved text requires no other special technique because no cuts are made, but text cutting is non-trivial. Because of loops, it's sometimes desirable to use a stencil font, especially at smaller scales where legibility is important. 1001 Fonts has a number of stencil fonts for free. At 10pt, some good fonts are Marsh, Spacedock, and Allerta.

== Troubleshooting ==

=== File doesn't appear in laser cutter after successful download ===
If the laser cutter has 99 files loaded into it, new files will not show up. To fix this, open up RDWorks8, and on the right side, select the Doc tab. Inside that tab, click Read to read all the files in the laser cutter, and then click Delete all.
[[Image:laser_cutter_read_files.png|thumb|right|upright=3|alt=read files | This is the button used to read stored files from the laser cutter.]] [[Image:laser_cutter_delete_all_files.png|thumb|right|upright=3|alt=delete all files | This is the button used to delete all stored files from the laser cutter to make room for new ones.]]

== Maintenance==

'''Please don't perform any maintenance on the machine (including cleaning lenses/mirrors or aligning mirrors) unless you've specifically trained on it.'''

* TEMP note: some check(s) may be included outside of maintenance so a user can trigger a maintenance notification
* DON'T - let someone who has been trained do it
* how to tell if the lens is dirty (or getting old?)
* how to tell if the mirrors are dirty
** Cleaning the mirrors
*** ethanol solution? isopropanol? - see manual.
*** fabric must be non scratch - see manual.
* Checking and performing mirror alignment
** Safety - remove gratings and any other reflective surfaces before any maintenance that requires disabling the door sensors.
** TEMP note: in restrospect the alignment was a very dangerous situation. mirror paths were not checked before powering on the laser with the door open with many people around. (or maybe nigel is just insanely good at configuring mirrors... still... reddit.com/r/OSHA)
** Tape test - mirrors 1,2,3 and their corresponding exits. Slightly propped laser tube.
** vertical/horizontal alignment by brass dial.
* Checking chiller tank water volume
** Chiller alarm - what does it mean
** Checking tank water volume
** Refilling tank water
* Cleaning the bed and waste drawer (this section probably should be moved to usage)

Signs:
* <strike>Don't open front/back passthrough doors (for now)</strike>
* <strike>Fire extinguishers - which to use for what fire</strike>
* Approved materials
* <strike>careful when raising bed, dont crash into laser head</strike>
* move laser head out of the way before opening the lid
* power off the laser before opening the lid ???
* <strike>watch the laser while it is cutting</strike>

Todos:
* <strike>Move the machine further away from the right wall so we can get to the power switch.</strike>
* <strike>label the water squirt bottle as for fires and not to remove</strike>

== Chlorine material test ==

Before you cut any new material you *must* check that it is safe to cut; specifically that it will not produce chlorine gas when it is burned by the cutting laser. Chlorine is extremely dangerous in its gaseous form and so must be avoided at all costs.

To test a new material, you'll need a sample of the material, a small copper rod (about the thickness of a coat hanger), a pliars, and a handheld propane torch. We'll test for the presence of chlorine by burning a sample of the material in a high temperature propane flame and observe the visible emission spectra. Chrlorine produces a bright green light when burned, and so will be very obvious when you're testing your material.

First, turn on the ventilation on the Sparkle Forge. The switch for this is under the sign that says "For Non-Laser Fires Only", and above the non-laser fire extinguisher. Then, light the propane torch and set it to rest upright on a stable surface. Taking the pliar, hold the piece of copper in the blue part of the flame to heat it. As the copper begins to heat sufficiently it'll cause the flame to turn an orange color. A consistent orange color means that the copper has no residue material on its surface and so is clean enough to use as a test. If you observe non-orange flames when you burn the copper you may need to clean in further, either by waiting for the excess material to burn off, or by scrubbing the surface of the copper when it has cooled.

Once the copper is burning, take the hot copper and melt a sample of the new material onto it. For example if you were testing a new form of plastic you can roll the hot copper rod on the material, melting some of it onto the copper rod's surface.

With this done, place the copper rod back into the blue part of the flame. Observe the colors of the emission spectra from the new material burning. If you observe a bright green color, then the material contains chlorine and thus *must not* be burned further. Ventilate your surrounding area to avoid breathing it in. If you observe no green color as you burn your material sample, then the material is likely safe to use with the laser cutter.

Here is a video example by Zach in NYCResistor with a known good and known bad material: https://www.youtube.com/watch?v=D0_4NLmeSTI

== BANNED MATERIALS (NEVER USE THESE) ==

These materials '''must not be used in the laser cutter'''.

{|border="1" cellpadding="5" cellspacing="0"
|-
! colspan="10" bgcolor="#ccc" | Bad materials
|-
! Material
! Notes
|-
| PVC || Contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| Vinyl || Most contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| PVC Foams || Most contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| Foam Core || Usually made with PVC which is harmful as listed above.
|-
| Styrofoam || Can cause flash fires
|-
| Polycarbonate or PETG || Does not cut. TAP plastics sells both this and acrylic. '''Be sure to read your labels when purchasing material'''. Lexan is the trade name for Polycarbonate, while Plexiglass is the trade name for acrylic.
|-
| ABS || Gives off hydrogen cyanide which can kill you and also may damage the laser optics.
|-
| Fiberglass || Contains complex epoxies which will cause fires, chlorine, and cyanide. Also contains glass which will not cut.
|-
| Metals || Cannot be etched by this type of laser. Also is harmful as the reflective surface may cause the laser to be reflected back up to the head, damaging it. If someone claims to be etching metal using this type of laser then they are etching a metal with a plastic coating, anodized surface, or some other etchable surface on top.

== Known good materials ==

These materials are known to be ok for use with the laser cutter. The speed and power of the laser cutter will need to be set appropriately for the material and thickness in use. Below is a table showing the suggested settings when cutting or etching them.

Power 3.5 produces very light engraving, almost non-existent, with no engraving at the beginnings of cuts. Above power 5, little difference is visible, but powdery soot becomes more prevalent. Power 5 seems to be the best setting to produce frosted effects. If you are engraving with the paper still on, you may want to go higher (do a test)

== Sourcing Material ==

In general, you can get stuff from Amazon, but you have to wait for shipping.

For plastics: [http://www.google.com/maps/place/TAP+Plastics/@37.7711648,-122.4207603,17z/data=!3m1!4b1!4m5!3m4!1s0x808f7e27351bb079:0x7e3610d7dc178b10!8m2!3d37.7711648!4d-122.4185663 Tap Plastics] is nearby Noisebridge, but is expensive, [http://eplastics.com eplastics] is cheaper but you need to wait for shipping, and [https://www.google.com/maps/place/Mr.+Plastics/@37.7091519,-122.1546962,17z/data=!3m1!4b1!4m5!3m4!1s0x808f8fe7938349a3:0xafcb2526326faccd!8m2!3d37.7091519!4d-122.1525022 Mr. Plastics] is cheapest but is in San Leandro.

== How do I send files to the Laser computer over the internet? ==

Send your files directly to the laser cutter through this URL [https://cloud.disroot.org/s/bFv70wtK9xQuyp3], which is kindly hosted for us by [https://disroot.org/en| Disroot.org] via [https://nextcloud.com/| Nextcloud].

All files are uploaded directly to ''\My Documents\PUT YOUR FILES HERE (IN YOUR OWN FOLDER)\Uploads for Noisebridge Lasercutter\''

Please move any files you upload to your own folder asap.

== Ok, I created a folder for my laser cutter files, but can I access them over the internet? ==
Yes, this is now possible as of 01/2018.

# Double check you made a folder inside ''\My Documents\PUT YOUR FILES HERE (IN YOUR OWN FOLDER)\''
# Ping @James on Slack with the name of your folder.
# Be sure to mention if you need a password added to your folder.
# Wait a day for the share link to be activated and sent to you.

== Troubleshooting ==

=== Help! All the menu options turned to gibberish! ===
The RDWorks software can be buggy. Go to the top menu, the right-most or or 2nd-right-most tab will have a Language option. Select English.
When that happens, the bed size settings might also have changed. Double check Config -> Document Settings (?). The proper settings are 1300mm × 900mm.
(TODO: need to double check the exact menu labels, doing this from memory at the moment)

=== SOLIDWORKS ===
Apparently DXFs exported from Solidworks (at least v 2017) break when directly imported into RDWorks. The workaround is to import the DXF into Inkscape and re-export it from there.

== How to get trained to use the laser cutter ==

# Ask a trainer if they will train you
# Schedule a time with the trainer
## The laser training class size is limited to 5 students, so that everyone can see how to operate the laser.
# Get trained
# Get your name on the list of users before the first time you use the machine

The laser training class is pay-what-you-can, and the recommended minimum donation is $20.

== Basic Safety ==
The laser cutter is generally a very safe machine to use. However, as with all industrial machines, you need to treat it with respect. The main safety concerns are creating fires, hurting your eyes or skin, getting crushed by the machine, and creating toxic fumes.

The basics:
* ALWAYS MONITOR THE LASER BEAM CUTTING YOUR WORK!
* DO NOT STARE DIRECTLY BECAUSE BURN-GENERATED VISIBLE LIGHT IS VERY BRIGHT!
* USE YOUR PERIPHERAL VISION!
* OPEN THE LID if you see a fire
* BLOW IT OUT if the fire keeps burning
* DON'T CUT UNAPPROVED MATERIALS!
* MAKE SURE THE WINDOWS BY THE BATHROOM ARE CLOSED SO YOU DON'T FUMIGATE NOISEBRIDGE

=== Fire ===

[[Image:Laser_water_estop.jpg|thumb|right|upright=3|alt=Laser cutter with water and estop| The water squirt bottle is sitting on top of the laser, and the estop is the round red button.]]

You can really hurt yourself or burn the building down with this machine. If you follow the safety rules, the chances of you causing this is close to zero. Some materials are very flammable on the laser cutter, and shouldn't be cut. Never cut an unapproved material, or a material you can't identify. A laser beam can also initiate a fire if the speed of the cut is too slow or the laser power is set too high.

Ways to not cause fires:
* ALWAYS MONITOR THE LASER CUTTER WHENEVER IT IS CUTTING AS FIRES CAN HAPPEN. The laser affects your material by heating it. Your job can change in seconds with the accumulation of heat in your material. Never leave the room while the laser is in operation. If you leave the laser unattended, your access to the laser cutter will be permanently revoked.
* Use reasonable speed/power settings. Start with the recommended speed/power settings for your material. Be patient - resist the temptation to crank the power and speed to rush through your job. This can cause fires.
** There will be some light when material is cut. This light at the point of lasing may be ok as long as it stays with the motion of the laser. If a flame appears while the laser is in operation, stop your job and try again with lower heat settings.
* Know where the fire extinguisher is in case of a fire. The ONLY fire extinguisher that should be used on the laser cutter is the halotron extinguisher right next to the laser cutter. Other fire extinguishers are corrosive and will ruin the machine.

How to put out a fire:
* Push the estop. (To turn the machine back on after the estop was hit, you need to switch the power switch on the right hand side of the machine off and on again).
* Open the lid.
* If it's small, try and blow it out.
* If it's smallish, try and squirt it out with the water squirt bottle sitting on the right hand side of the machine.
* If that doesn't work, use the halotron fire extinguisher to the right of the laser cutter. Aim it at the base of the flame.

=== Damage to eyes and skin ===
The laser beam can instantly and permanently blind you. It can also burn your skin.
* The lid's window will block the infrared laser beam, but it doesn't block the visible light produced by the burn. THE VISIBLE LIGHT CAN BE BRIGHT ENOUGH TO DAMAGE YOUR RETINA! DO NOT STARE DIRECTLY AT THE CUT! Use your peripheral vision.
* You don't ever want any part of your body in contact with the beam.
* As long as the door is closed, you're safe to look at the laser. There are interlocks on the door that help ensure the laser never operates with the doors open. Don't disable them.

=== Crushing danger ===

The laser cutter is a dumb machine. It doesn't care whether your hand is in the way when it's moving. The head can move when the door is open. Always make sure everyone's hands are out of the machine before moving the head.

Also be very careful not to crash the head into other parts of the machine. Be very careful when moving the z-axis to not crash the head into the bed, and to not move the z-axis if the focus length acrylic circle is under the lens.

If you need something to weigh down your material, use the magnetic balls or beanbags that are kept near the laser; nothing else. Do not let the laser head crash into these; if it does immediately stop the job.

Be *very* careful to not put the beanbags (or any other material) in such a situation where they may be dragged by the head. The head should never bump into anything, and *especially* never drag anything.

=== Fumes ===
The laser cutter burns the things it's cutting, which can create toxic fumes.
* ONLY CUT APPROVED MATERIALS. Cutting nonapproved materials can release really toxic gases, including chlorine and cyanide. These are really bad for humans, as well as being very damaging to the laser cutter.
* The ventilation fan should always be running if the laser cutter is on, even if it's not cutting. It's currently wired such that you can't turn on the laser cutter without the fan turning on, but please make sure it's running.

== Care of the machine ==

'''Please don't perform any maintenance on the machine (including cleaning lenses/mirrors or aligning mirrors) unless you've specifically trained on it.'''

The laser cutter is finely calibrated piece of machinery. Please close the lid gently, and do not push or jar the machine at any time. Do not lean or press on the tray - it's fragile, and needs to be perfectly flat for the laser cutter to cut properly. If you take the honeycomb bed or slats out, please be ULTRA CAREFUL with them - put them somewhere where they won't get damaged or warped.

== Paying for your laser time ==

The laser cutter has parts that wear out over time, which can be quite costly to replace, especially the laser tube. A new tube costs several thousand dollars. Thus, we require people to pay for the time on the laser they use, so we can pay for new parts. The cost for using the laser cutter is $5 per hour of cutting time.

To figure out how much time your job takes, press the File button, select your file, and then select Work Time from the menu. It will tell you in hours:minutes.seconds.

There is a laser cutter donation box on the wall of the Sparkle Forge room. Please pay for the cutting time you actually use, even if you end up running your job multiple times.

== Workflows ==

=== Overall Workflow ===

This is the overall structure of the workflow. Each part is elaborated below.

# Laser start up
# Material setup
# Convert file to DXF
# Load file onto the machine
# Dry run
# Cut/Engrave
# Laser shut down
# Cleanup

=== Laser start up ===

[[Image:Laser_chiller.jpg|thumb|right|upright=3|alt=Laser chiller| The laser chiller is the box on the bottom left of this photograph. If the laser doesn't beep when it turns on, you should turn on the chiller manually.]]

# Turn on power and ensure that the fan and chiller are running. If you do not hear beeps when the laser starts up, the chiller is not running and you must turn it on.
# Move the head as far forward and right as possible, close to the controls

=== Material setup ===

# Clean the bed of any scraps that may be on it
# Move the cut head as far forward and right as possible (near the controls)
# Raise the laser head as far up as possible
# Raise the bed to the desired height, watching the laser head to avoid crashes
# Move the laser head as far back and right as possible
# Place material on the bed
# Focus the laser (do at least for each distinct thickness, optimally do for each piece of material)

=== Focusing the laser ===

[[Image:Laser_shelf.jpg|thumb|right|upright=3|alt=Shelf by laser cutter | This is the shelf to the left of the laser cutter. The acrylic disks used for focusing the laser are in the toolbox with the yellow lid.]]

Noisebridge has acryllic disks cut to various thicknesses that can be used to accurately focus the laser. Specifically the laser head needs to be locked to 8mm above the surface of the material you're cutting.

# Place the material on the cut bed
# Move the cut head to the center of the area to cut, watching the laser head to avoid crashes w/ material
## Note that the honeycomb bed can move up and down (Z-axis) so if the material doesn't fit under, hit Z/U on the laser controls and navigate the menu until Z axis (or something similar) is selected. Then use the left and right arrows to move the bed up and down.
# Loosen the wing nut and raise the head all the way up
# Place the focusing discs on the material under the head
# Lower the head until it just touches the focusing disc (8mm above material)
# Lock the head in place (tighten the wing nut)
# Remove the focusing discs

=== Convert an image in Inkscape to a DXF file ===

# Load the image into Inkscape
# Set the different cut paths to different colors (for controlling settings, etc.)
# Perform any debugging steps (by default you should perform all of them b/c of errors in the laser software)
# Save as a DXF. Be sure to make the units be millimeters so that importing later will correctly scale the image.

=== Debugging DXF Problems ===

Sometimes exporting to DXF introduces bizarre extra lines. There are two things to try to debug. The first is to convert objects to paths:

# Select all the problematic shapes
# Path > Object to Path

If this fails to resolve the issue, you can try a more radical solution which will eliminate all bezier paths entirely:

# Select all the problematic shapes
# Convert bezier paths to lines (Extensions > Modify Path > Flatten Bezier).

Flatness 0.5 is good to start with. Smaller = better approximation of the curves. A lower flatness number takes more time to compute, but also produces a better approximation to the curve. Be sure to ungroup (sometimes multiple times) before trying this, as grouped objects cannot be flattened as a group. This is especially important for text which is by default a group (each character being a separate object in Inkscape once you've turned it into a path).

Sometimes need to select the path's directly with the path tool (but not the points!).

Also see http://www.pstoedit.net/ for conversion from svg to dxf files.

=== Loading into the laser cutter software ===

# Import the file with File > Import
# Resize as needed, tho if the file was exported w/ millimeter units, the software should also import the image with the correct size.
# Set the cut order:
##* EITHER Set the cut order to inside-out (Handle > Cut optimize > Inside to outside)
##* OR Manually specify cut order with the Set cut property tool (Edit > Set cutting property). See below for more details.
# Set the speed and power for the layers as necessary, and the process mode for each layer to either cut (for continuous line cutting) or dot (for dashed line cutting) or scan (for engraving)
# Optionally, simulate the cutting/engraving process.
# Download to the machine (Laser Work panel on the bottom right).

=== Manually specifying cut order ===

In the Set cutting property window (Edit > Set cutting property), you can manually re-order the cut paths. In the window, you'll see an image of the workpiece, and to its right, two lists of paths. When you first open the window, all of the cut paths are in the left. If you select a path (either in the image or in the list) and click the button labeled ">>", this path will be transferred to the end of the right list of paths. If you click ">>>", all of the paths in the left list will be moved to the end of the right list (preserving order). Similarly, clicking "<<<" will move the right list to the end of the left list. If you select a cut path in the right list, the up and down arrow buttons will reorder that path in the chosen direction.

=== Loading speed and power settings from library ===

# In the top right panel, double click the layer of interest
# Click "Load parameters from library"
# Select the library item
# Click "Load"

=== Saving power and speed settings to library ===

# In the top right panel, double click the layer of interest
# Make sure the layer is set to the desired parameters
# Click "Load parameters from library"
# Click "Save as"
# Enter a name and optionally some notes
# Click "Ok"

=== Simulation ===

# Open the simulation window with either Edit > Preview or the toolbar button labelled with a monitor.
# Click the Simulation button in the right panel

=== Cutting ===

# Select the file to use using the File button
# Move the head to the initial guess origin with the arrow buttons
# Test the frame with the Frame button adjust origin as necessary
# Set the origin by pressing Origin
# Test the cut by turning the laser power off and pressing the Start/Pause button
# Turn the laser power on
# Cut by pressing the Start/Pause button
# It is generally a good idea to put the laser head into one of the top corners and resetting origin before opening the laser if you plan on adding new material to avoid collisions with a moving head.

=== Engraving ===

In the laser software, open the layers you wish to engrave in the layer parameters panel, and send the processing mode to "Scan". This will do a raster scan of the region bounded by the paths in that layer. An even-odd rule is used to assign regions to the "inside" vs "outside" of the engraving.

=== Cancel a cut/dry run ===

# Pause with the Start/Pause button
# Cancel and move back to the origin with the Esc button

=== Laser shut down ===

# Move the head as far forward and right as possible (near the controls)
# Raise the laser head as far up as possible
# Set origin with the origin button (this helps avoid the laser swinging across the bed later)
# Let the fan run for a little bit (~30 seconds)
# Turn the power off

=== Cleanup ===

[[Image:Laser_tray.jpg|thumb|right|upright=3|alt=Laser bottom tray| This is the bottom tray of the laser, which should be cleaned out after use.]]

# Remove pieces of material scrap left on the bed
# Open the tray door on the front bottom and empty the scraps left there

=== Calculating work time ===

On the computer:

* Open the simulation window (see above). Total work time and time of laser use are displayed in the top right. Donations should be calculated by laser use, not total work time.

On the machine:

* Whole file: File > Select file > Right Arrow > Work Time > Enter
* Current run: Pause the cut, then check time at the bottom right

== Fusion 360 ==
Fusion 360 is a free CAD (Computer Aided Design) program from Autodesk for designing 3D parts, and arguably the best one currently available. If you're designing something complex on the laser cutter, particularly with multiple parts that need to fit together, I highly recommend it over drawing programs like Inkscape. It also has CAM (Computer Aided Manufacturing) capabilities, which makes it very useful for CNC machining and laser cutting. There's a copy of the software on the laser cutter computer, and you can download it [http://www.autodesk.com/products/fusion-360/overview here]. It's free as long as you make less than $100k per year using it.

=== Workflow 1: The Quick and Dirty Way ===
This is the fastest way, and works a lot of the time
# Make sure your sketch only contains straight lines, arcs, and circles, and no spline curves. If your sketch has splines, go to [[#Workflow 3: The Long Way]]
# Make sure your part is designed using a single sketch, and that you want to cut all the lines in that sketch. If not, go to [[#Workflow 2: The Middle Ground]]
# Right click on your sketch and click Save As DXF
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]

=== Workflow 2: The Middle Ground ===
If you're not sure, this is probably where you should start.
# Make sure your sketch only contains straight lines, arcs, and circles, and no spline curves. If your sketch has splines, go to [[#Workflow 3: The Long Way]]
# Right click on the top surface of the part you want to cut, and click Create Sketch
# Hit the P key to open the Project dialog box, then select the top surface of your part, and any other lines you want to cut
# Hit OK, then remove any lines you don't want cut
# Open the Sketches folder near the top of the tree, then right click your new sketch and click Save As DXF
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]

=== Workflow 3: The Long Way ===
This allows more complicated things like exporting splines, which doesn't work with the above methods, kerf compensation, which makes your parts fit together snugly, but you can also use the above methods and then do it in RDWorks, or lead-ins and lead-outs, which can make for a cleaner cut, but I can't figure out how to get RDWorks to import correctly.
# Design a part to be laser cut by drawing a 2D sketch and extruding it
# Go to the CAM workspace by clicking the Model button in the top left, then selecting CAM
# Select the Waterjet operation (if you don't see this, turn it on under Preferences -> Preview)
## Set Type to Laser Cutting
## Select the Cutting Mode, either Through - Auto or Etch
## Look up the kerf of the material you're cutting in the [[#Known good materials]] section, and enter that in Kerf Width, or if your material's not listed, cut one a [http://www.thingiverse.com/thing:1166680 kerf gauge] and put the result in the wiki. The kerf changes depending on the thickness, speed and power. Setting a larger kerf width will make your parts fit tighter, and setting a smaller kerf will make them looser.
## Select the contours of your part that you want to cut
## Go to the Passes tab, and change Compensation Type to In Computer
## Hit OK to close the dialog box, and you can see a preview of your tool path. You can go back to edit it by double clicking the contour operation in the tree on the left
# To export to DXF, click the Post Process button, which says G1 G2. Make sure rdworkslaser is selected as your post processor, type a name for the export and hit Post. Then select the folder to put it in.
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]
# Fusion automatically orders the cuts from inside out and in the fastest order, but RDWorks doesn't always respect that order, so you may need to optimize the cut order again

=== Advanced Options ===
# If you're using your own computer for the first time and not the laser cutter desktop, you have to enable the laser cutter support which is still in beta, by clicking on your name in the top right, then Preferences, Preview, and checking "CAM - Waterjet/Laser/Plasma cutter support". You will also need to download the custom post processor that we use for this laser.
# There's a simulate button to the left of the Post Process button, if you want to do it in Fusion
# If you want to disable or tweak the lead ins and lead outs, you can go to the Linking tab. Lead ins and lead outs can fix the bump you get on the side of your part where the laser started and stopped, but they also make extra cuts in your scrap material, which you may want to keep. In this tab you can also specify the Entry Position for each cut path.
# You can disable Kerf Compensation by settting Sideways Compensation to Center under the Passes tab, though this is not recommended

== Techniques ==

=== Kerf Compensation ===

For any given layer, you can compensate for the kerf (width of the cut) by opening it's settings and clicking the "Advance" button next to the "Seal" input box towards the middle-bottom. Enable sew compensation, and pick the direction and sew width (kerf size). The inward direction will make the actual cut move toward the inside of a closed cut path, outward will move it towards the outside.

In general, for cuts on the outside, you want to move outward, to move the actual cut edge be exactly where the path is in your design. For cuts on the inside, you want to use the inward direction.

=== Negative Space Engraving ===

You can engrave a vector shape with a hole in the middle of it, so that you get enclosed portions that are not engraved in the middle of fully engraved portions. To do this, when you construct the image in your editor of choice, simply perform subtraction between the relevant paths, to remove the inner part. In the RDWorks laser software, the two paths will show up, and be independently editable (making them look like just two distinct paths to engrave), but they will engrave correctly as a negative space. Obviously test this w/ your software; this technique is known to work using Inkscape.

=== Nest & Waste Less Material ===

As of 01/2018 you can use the industrial strength [http://deepnest.io/#quickstart Deepnest] installed on the [[Kaitian_CM1309|Laser Cutter computer]] + [[CollaborationStation|Collaboration Station]] in Hackitorium. We have an unlimited subscription available to laser users, which is compatible with both ''DXF'', ''Corel CDR'' and ''SVG'' formats. Please ask if you need login credentials. Also available from the same author for free is [http://svgnest.com/| SVGNest, which can be used by clicking here].

=== Text Cutting ===

In Inkscape, after converting the text object to a path, it's necessary to ungroup the text as well, to create separate paths, prior to flattening the bezier curves.

If you're using a cursive font and want everything to be one piece, convert the text object to a path, and use Path > Union. This tool in general is quite useful for merging paths that have been independently drawn but need to be merged into a single path. For example, if you made two overlapping circles, without this the cutter would just cut the two circles, which leads to a lemon-shaped piece in the center. If you union the paths, it will cut an outline as well. Path > Union will not make any holes in the figure go away, it only gets rid of cuts passing through area covered by another shape.

Engraved text requires no other special technique because no cuts are made, but text cutting is non-trivial. Because of loops, it's sometimes desirable to use a stencil font, especially at smaller scales where legibility is important. 1001 Fonts has a number of stencil fonts for free. At 10pt, some good fonts are Marsh, Spacedock, and Allerta.

== Troubleshooting ==

=== File doesn't appear in laser cutter after successful download ===
If the laser cutter has 99 files loaded into it, new files will not show up. To fix this, open up RDWorks8, and on the right side, select the Doc tab. Inside that tab, click Read to read all the files in the laser cutter, and then click Delete all.
[[Image:laser_cutter_read_files.png|thumb|right|upright=3|alt=read files | This is the button used to read stored files from the laser cutter.]] [[Image:laser_cutter_delete_all_files.png|thumb|right|upright=3|alt=delete all files | This is the button used to delete all stored files from the laser cutter to make room for new ones.]]

== Maintenance==

'''Please don't perform any maintenance on the machine (including cleaning lenses/mirrors or aligning mirrors) unless you've specifically trained on it.'''

* TEMP note: some check(s) may be included outside of maintenance so a user can trigger a maintenance notification
* DON'T - let someone who has been trained do it
* how to tell if the lens is dirty (or getting old?)
* how to tell if the mirrors are dirty
** Cleaning the mirrors
*** ethanol solution? isopropanol? - see manual.
*** fabric must be non scratch - see manual.
* Checking and performing mirror alignment
** Safety - remove gratings and any other reflective surfaces before any maintenance that requires disabling the door sensors.
** TEMP note: in restrospect the alignment was a very dangerous situation. mirror paths were not checked before powering on the laser with the door open with many people around. (or maybe nigel is just insanely good at configuring mirrors... still... reddit.com/r/OSHA)
** Tape test - mirrors 1,2,3 and their corresponding exits. Slightly propped laser tube.
** vertical/horizontal alignment by brass dial.
* Checking chiller tank water volume
** Chiller alarm - what does it mean
** Checking tank water volume
** Refilling tank water
* Cleaning the bed and waste drawer (this section probably should be moved to usage)

== Chlorine material test ==

Before you cut any new material you *must* check that it is safe to cut; specifically that it will not produce chlorine gas when it is burned by the cutting laser. Chlorine is extremely dangerous in its gaseous form and so must be avoided at all costs.

To test a new material, you'll need a sample of the material, a small copper rod (about the thickness of a coat hanger), a pliars, and a handheld propane torch. We'll test for the presence of chlorine by burning a sample of the material in a high temperature propane flame and observe the visible emission spectra. Chrlorine produces a bright green light when burned, and so will be very obvious when you're testing your material.

First, turn on the ventilation on the Sparkle Forge. The switch for this is under the sign that says "For Non-Laser Fires Only", and above the non-laser fire extinguisher. Then, light the propane torch and set it to rest upright on a stable surface. Taking the pliar, hold the piece of copper in the blue part of the flame to heat it. As the copper begins to heat sufficiently it'll cause the flame to turn an orange color. A consistent orange color means that the copper has no residue material on its surface and so is clean enough to use as a test. If you observe non-orange flames when you burn the copper you may need to clean in further, either by waiting for the excess material to burn off, or by scrubbing the surface of the copper when it has cooled.

Once the copper is burning, take the hot copper and melt a sample of the new material onto it. For example if you were testing a new form of plastic you can roll the hot copper rod on the material, melting some of it onto the copper rod's surface.

With this done, place the copper rod back into the blue part of the flame. Observe the colors of the emission spectra from the new material burning. If you observe a bright green color, then the material contains chlorine and thus *must not* be burned further. Ventilate your surrounding area to avoid breathing it in. If you observe no green color as you burn your material sample, then the material is likely safe to use with the laser cutter.

Here is a video example by Zach in NYCResistor with a known good and known bad material: https://www.youtube.com/watch?v=D0_4NLmeSTI

== BANNED MATERIALS (NEVER USE THESE) ==

These materials '''must not be used in the laser cutter'''.

{|border="1" cellpadding="5" cellspacing="0"
|-
! colspan="10" bgcolor="#ccc" | Bad materials
|-
! Material
! Notes
|-
| PVC || Contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| Vinyl || Most contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| PVC Foams || Most contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| Foam Core || Usually made with PVC which is harmful as listed above.
|-
| Styrofoam || Can cause flash fires
|-
| Polycarbonate or PETG || Does not cut. TAP plastics sells both this and acrylic. '''Be sure to read your labels when purchasing material'''. Lexan is the trade name for Polycarbonate, while Plexiglass is the trade name for acrylic.
|-
| ABS || Gives off hydrogen cyanide which can kill you and also may damage the laser optics.
|-
| Fiberglass || Contains complex epoxies which will cause fires, chlorine, and cyanide. Also contains glass which will not cut.
|-
| Metals || Cannot be etched by this type of laser. Also is harmful as the reflective surface may cause the laser to be reflected back up to the head, damaging it. If someone claims to be etching metal using this type of laser then they are etching a metal with a plastic coating, anodized surface, or some other etchable surface on top.

== Known good materials ==

These materials are known to be ok for use with the laser cutter. The speed and power of the laser cutter will need to be set appropriately for the material and thickness in use. Below is a table showing the suggested settings when cutting or etching them.

== How do I send files to the Laser computer over the internet? ==

Send your files directly to the laser cutter through this URL [https://cloud.disroot.org/s/bFv70wtK9xQuyp3], which is kindly hosted for us by [https://disroot.org/en| Disroot.org] via [https://nextcloud.com/| Nextcloud].

All files are uploaded directly to ''\My Documents\PUT YOUR FILES HERE (IN YOUR OWN FOLDER)\Uploads for Noisebridge Lasercutter\''

Please move any files you upload to your own folder asap.

== Ok, I created a folder for my laser cutter files, but can I access them over the internet? ==
Yes, this is now possible as of 01/2018.

# Double check you made a folder inside ''\My Documents\PUT YOUR FILES HERE (IN YOUR OWN FOLDER)\''
# Ping @James on Slack with the name of your folder.
# Be sure to mention if you need a password added to your folder.
# Wait a day for the share link to be activated and sent to you.

== Troubleshooting ==

=== Help! All the menu options turned to gibberish! ===
The RDWorks software can be buggy. Go to the top menu, the right-most or or 2nd-right-most tab will have a Language option. Select English.
When that happens, the bed size settings might also have changed. Double check Config -> Document Settings (?). The proper settings are 1300mm × 900mm.
(TODO: need to double check the exact menu labels, doing this from memory at the moment)

=== SOLIDWORKS ===
Apparently DXFs exported from Solidworks (at least v 2017) break when directly imported into RDWorks. The workaround is to import the DXF into Inkscape and re-export it from there.

== How to get trained to use the laser cutter ==

# Ask a trainer if they will train you
# Schedule a time with the trainer
## The laser training class size is limited to 5 students, so that everyone can see how to operate the laser.
# Get trained
# Get your name on the list of users before the first time you use the machine

The laser training class is pay-what-you-can, and the recommended minimum donation is $20.

== Basic Safety ==
The laser cutter is generally a very safe machine to use. However, as with all industrial machines, you need to treat it with respect. The main safety concerns are creating fires, hurting your eyes or skin, getting crushed by the machine, and creating toxic fumes.

The basics:
* ALWAYS MONITOR THE LASER BEAM CUTTING YOUR WORK!
* DO NOT STARE DIRECTLY BECAUSE BURN-GENERATED VISIBLE LIGHT IS VERY BRIGHT!
* USE YOUR PERIPHERAL VISION!
* OPEN THE LID if you see a fire
* BLOW IT OUT if the fire keeps burning
* DON'T CUT UNAPPROVED MATERIALS!
* MAKE SURE THE WINDOWS BY THE BATHROOM ARE CLOSED SO YOU DON'T FUMIGATE NOISEBRIDGE

=== Fire ===

[[Image:Laser_water_estop.jpg|thumb|right|upright=3|alt=Laser cutter with water and estop| The water squirt bottle is sitting on top of the laser, and the estop is the round red button.]]

You can really hurt yourself or burn the building down with this machine. If you follow the safety rules, the chances of you causing this is close to zero. Some materials are very flammable on the laser cutter, and shouldn't be cut. Never cut an unapproved material, or a material you can't identify. A laser beam can also initiate a fire if the speed of the cut is too slow or the laser power is set too high.

Ways to not cause fires:
* ALWAYS MONITOR THE LASER CUTTER WHENEVER IT IS CUTTING AS FIRES CAN HAPPEN. The laser affects your material by heating it. Your job can change in seconds with the accumulation of heat in your material. Never leave the room while the laser is in operation. If you leave the laser unattended, your access to the laser cutter will be permanently revoked.
* Use reasonable speed/power settings. Start with the recommended speed/power settings for your material. Be patient - resist the temptation to crank the power and speed to rush through your job. This can cause fires.
** There will be some light when material is cut. This light at the point of lasing may be ok as long as it stays with the motion of the laser. If a flame appears while the laser is in operation, stop your job and try again with lower heat settings.
* Know where the fire extinguisher is in case of a fire. The ONLY fire extinguisher that should be used on the laser cutter is the halotron extinguisher right next to the laser cutter. Other fire extinguishers are corrosive and will ruin the machine.

How to put out a fire:
* Push the estop. (To turn the machine back on after the estop was hit, you need to switch the power switch on the right hand side of the machine off and on again).
* Open the lid.
* If it's small, try and blow it out.
* If it's smallish, try and squirt it out with the water squirt bottle sitting on the right hand side of the machine.
* If that doesn't work, use the halotron fire extinguisher to the right of the laser cutter. Aim it at the base of the flame.

=== Damage to eyes and skin ===
The laser beam can instantly and permanently blind you. It can also burn your skin.
* The lid's window will block the infrared laser beam, but it doesn't block the visible light produced by the burn. THE VISIBLE LIGHT CAN BE BRIGHT ENOUGH TO DAMAGE YOUR RETINA! DO NOT STARE DIRECTLY AT THE CUT! Use your peripheral vision.
* You don't ever want any part of your body in contact with the beam.
* As long as the door is closed, you're safe to look at the laser. There are interlocks on the door that help ensure the laser never operates with the doors open. Don't disable them.

=== Crushing danger ===

The laser cutter is a dumb machine. It doesn't care whether your hand is in the way when it's moving. The head can move when the door is open. Always make sure everyone's hands are out of the machine before moving the head.

Also be very careful not to crash the head into other parts of the machine. Be very careful when moving the z-axis to not crash the head into the bed, and to not move the z-axis if the focus length acrylic circle is under the lens.

If you need something to weigh down your material, use the magnetic balls or beanbags that are kept near the laser; nothing else. Do not let the laser head crash into these; if it does immediately stop the job.

Be *very* careful to not put the beanbags (or any other material) in such a situation where they may be dragged by the head. The head should never bump into anything, and *especially* never drag anything.

=== Fumes ===
The laser cutter burns the things it's cutting, which can create toxic fumes.
* ONLY CUT APPROVED MATERIALS. Cutting nonapproved materials can release really toxic gases, including chlorine and cyanide. These are really bad for humans, as well as being very damaging to the laser cutter.
* The ventilation fan should always be running if the laser cutter is on, even if it's not cutting. It's currently wired such that you can't turn on the laser cutter without the fan turning on, but please make sure it's running.

== Care of the machine ==

'''Please don't perform any maintenance on the machine (including cleaning lenses/mirrors or aligning mirrors) unless you've specifically trained on it.'''

The laser cutter is finely calibrated piece of machinery. Please close the lid gently, and do not push or jar the machine at any time. Do not lean or press on the tray - it's fragile, and needs to be perfectly flat for the laser cutter to cut properly. If you take the honeycomb bed or slats out, please be ULTRA CAREFUL with them - put them somewhere where they won't get damaged or warped.

== Paying for your laser time ==

The laser cutter has parts that wear out over time, which can be quite costly to replace, especially the laser tube. A new tube costs several thousand dollars. Thus, we require people to pay for the time on the laser they use, so we can pay for new parts. The cost for using the laser cutter is $5 per hour of cutting time.

To figure out how much time your job takes, press the File button, select your file, and then select Work Time from the menu. It will tell you in hours:minutes.seconds.

There is a laser cutter donation box on the wall of the Sparkle Forge room. Please pay for the cutting time you actually use, even if you end up running your job multiple times.

== Workflows ==

=== Overall Workflow ===

This is the overall structure of the workflow. Each part is elaborated below.

# Laser start up
# Material setup
# Convert file to DXF
# Load file onto the machine
# Dry run
# Cut/Engrave
# Laser shut down
# Cleanup

=== Laser start up ===

[[Image:Laser_chiller.jpg|thumb|right|upright=3|alt=Laser chiller| The laser chiller is the box on the bottom left of this photograph. If the laser doesn't beep when it turns on, you should turn on the chiller manually.]]

# Turn on power and ensure that the fan and chiller are running. If you do not hear beeps when the laser starts up, the chiller is not running and you must turn it on.
# Move the head as far forward and right as possible, close to the controls

=== Material setup ===

# Clean the bed of any scraps that may be on it
# Move the cut head as far forward and right as possible (near the controls)
# Raise the laser head as far up as possible
# Raise the bed to the desired height, watching the laser head to avoid crashes
# Move the laser head as far back and right as possible
# Place material on the bed
# Focus the laser (do at least for each distinct thickness, optimally do for each piece of material)

=== Focusing the laser ===

[[Image:Laser_shelf.jpg|thumb|right|upright=3|alt=Shelf by laser cutter | This is the shelf to the left of the laser cutter. The acrylic disks used for focusing the laser are in the toolbox with the yellow lid.]]

Noisebridge has acryllic disks cut to various thicknesses that can be used to accurately focus the laser. Specifically the laser head needs to be locked to 8mm above the surface of the material you're cutting.

# Place the material on the cut bed
# Move the cut head to the center of the area to cut, watching the laser head to avoid crashes w/ material
## Note that the honeycomb bed can move up and down (Z-axis) so if the material doesn't fit under, hit Z/U on the laser controls and navigate the menu until Z axis (or something similar) is selected. Then use the left and right arrows to move the bed up and down.
# Loosen the wing nut and raise the head all the way up
# Place the focusing discs on the material under the head
# Lower the head until it just touches the focusing disc (8mm above material)
# Lock the head in place (tighten the wing nut)
# Remove the focusing discs

=== Convert an image in Inkscape to a DXF file ===

# Load the image into Inkscape
# Set the different cut paths to different colors (for controlling settings, etc.)
# Perform any debugging steps (by default you should perform all of them b/c of errors in the laser software)
# Save as a DXF. Be sure to make the units be millimeters so that importing later will correctly scale the image.

=== Debugging DXF Problems ===

Sometimes exporting to DXF introduces bizarre extra lines. There are two things to try to debug. The first is to convert objects to paths:

# Select all the problematic shapes
# Path > Object to Path

If this fails to resolve the issue, you can try a more radical solution which will eliminate all bezier paths entirely:

# Select all the problematic shapes
# Convert bezier paths to lines (Extensions > Modify Path > Flatten Bezier).

Flatness 0.5 is good to start with. Smaller = better approximation of the curves. A lower flatness number takes more time to compute, but also produces a better approximation to the curve. Be sure to ungroup (sometimes multiple times) before trying this, as grouped objects cannot be flattened as a group. This is especially important for text which is by default a group (each character being a separate object in Inkscape once you've turned it into a path).

Sometimes need to select the path's directly with the path tool (but not the points!).

Also see http://www.pstoedit.net/ for conversion from svg to dxf files.

=== Loading into the laser cutter software ===

# Import the file with File > Import
# Resize as needed, tho if the file was exported w/ millimeter units, the software should also import the image with the correct size.
# Set the cut order:
##* EITHER Set the cut order to inside-out (Handle > Cut optimize > Inside to outside)
##* OR Manually specify cut order with the Set cut property tool (Edit > Set cutting property). See below for more details.
# Set the speed and power for the layers as necessary, and the process mode for each layer to either cut (for continuous line cutting) or dot (for dashed line cutting) or scan (for engraving)
# Optionally, simulate the cutting/engraving process.
# Download to the machine (Laser Work panel on the bottom right).

=== Manually specifying cut order ===

In the Set cutting property window (Edit > Set cutting property), you can manually re-order the cut paths. In the window, you'll see an image of the workpiece, and to its right, two lists of paths. When you first open the window, all of the cut paths are in the left. If you select a path (either in the image or in the list) and click the button labeled ">>", this path will be transferred to the end of the right list of paths. If you click ">>>", all of the paths in the left list will be moved to the end of the right list (preserving order). Similarly, clicking "<<<" will move the right list to the end of the left list. If you select a cut path in the right list, the up and down arrow buttons will reorder that path in the chosen direction.

=== Loading speed and power settings from library ===

# In the top right panel, double click the layer of interest
# Click "Load parameters from library"
# Select the library item
# Click "Load"

=== Saving power and speed settings to library ===

# In the top right panel, double click the layer of interest
# Make sure the layer is set to the desired parameters
# Click "Load parameters from library"
# Click "Save as"
# Enter a name and optionally some notes
# Click "Ok"

=== Simulation ===

# Open the simulation window with either Edit > Preview or the toolbar button labelled with a monitor.
# Click the Simulation button in the right panel

=== Cutting ===

# Select the file to use using the File button
# Move the head to the initial guess origin with the arrow buttons
# Test the frame with the Frame button adjust origin as necessary
# Set the origin by pressing Origin
# Test the cut by turning the laser power off and pressing the Start/Pause button
# Turn the laser power on
# Cut by pressing the Start/Pause button
# It is generally a good idea to put the laser head into one of the top corners and resetting origin before opening the laser if you plan on adding new material to avoid collisions with a moving head.

=== Engraving ===

In the laser software, open the layers you wish to engrave in the layer parameters panel, and send the processing mode to "Scan". This will do a raster scan of the region bounded by the paths in that layer. An even-odd rule is used to assign regions to the "inside" vs "outside" of the engraving.

=== Cancel a cut/dry run ===

# Pause with the Start/Pause button
# Cancel and move back to the origin with the Esc button

=== Laser shut down ===

# Move the head as far forward and right as possible (near the controls)
# Raise the laser head as far up as possible
# Set origin with the origin button (this helps avoid the laser swinging across the bed later)
# Let the fan run for a little bit (~30 seconds)
# Turn the power off

=== Cleanup ===

[[Image:Laser_tray.jpg|thumb|right|upright=3|alt=Laser bottom tray| This is the bottom tray of the laser, which should be cleaned out after use.]]

# Remove pieces of material scrap left on the bed
# Open the tray door on the front bottom and empty the scraps left there

=== Calculating work time ===

On the computer:

* Open the simulation window (see above). Total work time and time of laser use are displayed in the top right. Donations should be calculated by laser use, not total work time.

On the machine:

* Whole file: File > Select file > Right Arrow > Work Time > Enter
* Current run: Pause the cut, then check time at the bottom right

== Fusion 360 ==
Fusion 360 is a free CAD (Computer Aided Design) program from Autodesk for designing 3D parts, and arguably the best one currently available. If you're designing something complex on the laser cutter, particularly with multiple parts that need to fit together, I highly recommend it over drawing programs like Inkscape. It also has CAM (Computer Aided Manufacturing) capabilities, which makes it very useful for CNC machining and laser cutting. There's a copy of the software on the laser cutter computer, and you can download it [http://www.autodesk.com/products/fusion-360/overview here]. It's free as long as you make less than $100k per year using it.

=== Workflow 1: The Quick and Dirty Way ===
This is the fastest way, and works a lot of the time
# Make sure your sketch only contains straight lines, arcs, and circles, and no spline curves. If your sketch has splines, go to [[#Workflow 3: The Long Way]]
# Make sure your part is designed using a single sketch, and that you want to cut all the lines in that sketch. If not, go to [[#Workflow 2: The Middle Ground]]
# Right click on your sketch and click Save As DXF
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]

=== Workflow 2: The Middle Ground ===
If you're not sure, this is probably where you should start.
# Make sure your sketch only contains straight lines, arcs, and circles, and no spline curves. If your sketch has splines, go to [[#Workflow 3: The Long Way]]
# Right click on the top surface of the part you want to cut, and click Create Sketch
# Hit the P key to open the Project dialog box, then select the top surface of your part, and any other lines you want to cut
# Hit OK, then remove any lines you don't want cut
# Open the Sketches folder near the top of the tree, then right click your new sketch and click Save As DXF
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]

=== Workflow 3: The Long Way ===
This allows more complicated things like exporting splines, which doesn't work with the above methods, kerf compensation, which makes your parts fit together snugly, but you can also use the above methods and then do it in RDWorks, or lead-ins and lead-outs, which can make for a cleaner cut, but I can't figure out how to get RDWorks to import correctly.
# Design a part to be laser cut by drawing a 2D sketch and extruding it
# Go to the CAM workspace by clicking the Model button in the top left, then selecting CAM
# Select the Waterjet operation (if you don't see this, turn it on under Preferences -> Preview)
## Set Type to Laser Cutting
## Select the Cutting Mode, either Through - Auto or Etch
## Look up the kerf of the material you're cutting in the [[#Known good materials]] section, and enter that in Kerf Width, or if your material's not listed, cut one a [http://www.thingiverse.com/thing:1166680 kerf gauge] and put the result in the wiki. The kerf changes depending on the thickness, speed and power. Setting a larger kerf width will make your parts fit tighter, and setting a smaller kerf will make them looser.
## Select the contours of your part that you want to cut
## Go to the Passes tab, and change Compensation Type to In Computer
## Hit OK to close the dialog box, and you can see a preview of your tool path. You can go back to edit it by double clicking the contour operation in the tree on the left
# To export to DXF, click the Post Process button, which says G1 G2. Make sure rdworkslaser is selected as your post processor, type a name for the export and hit Post. Then select the folder to put it in.
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]
# Fusion automatically orders the cuts from inside out and in the fastest order, but RDWorks doesn't always respect that order, so you may need to optimize the cut order again

=== Advanced Options ===
# If you're using your own computer for the first time and not the laser cutter desktop, you have to enable the laser cutter support which is still in beta, by clicking on your name in the top right, then Preferences, Preview, and checking "CAM - Waterjet/Laser/Plasma cutter support". You will also need to download the custom post processor that we use for this laser.
# There's a simulate button to the left of the Post Process button, if you want to do it in Fusion
# If you want to disable or tweak the lead ins and lead outs, you can go to the Linking tab. Lead ins and lead outs can fix the bump you get on the side of your part where the laser started and stopped, but they also make extra cuts in your scrap material, which you may want to keep. In this tab you can also specify the Entry Position for each cut path.
# You can disable Kerf Compensation by settting Sideways Compensation to Center under the Passes tab, though this is not recommended

== Techniques ==

=== Kerf Compensation ===

For any given layer, you can compensate for the kerf (width of the cut) by opening it's settings and clicking the "Advance" button next to the "Seal" input box towards the middle-bottom. Enable sew compensation, and pick the direction and sew width (kerf size). The inward direction will make the actual cut move toward the inside of a closed cut path, outward will move it towards the outside.

In general, for cuts on the outside, you want to move outward, to move the actual cut edge be exactly where the path is in your design. For cuts on the inside, you want to use the inward direction.

=== Negative Space Engraving ===

You can engrave a vector shape with a hole in the middle of it, so that you get enclosed portions that are not engraved in the middle of fully engraved portions. To do this, when you construct the image in your editor of choice, simply perform subtraction between the relevant paths, to remove the inner part. In the RDWorks laser software, the two paths will show up, and be independently editable (making them look like just two distinct paths to engrave), but they will engrave correctly as a negative space. Obviously test this w/ your software; this technique is known to work using Inkscape.

=== Nest & Waste Less Material ===

As of 01/2018 you can use the industrial strength [http://deepnest.io/#quickstart Deepnest] installed on the [[Kaitian_CM1309|Laser Cutter computer]] + [[CollaborationStation|Collaboration Station]] in Hackitorium. We have an unlimited subscription available to laser users, which is compatible with both ''DXF'', ''Corel CDR'' and ''SVG'' formats. Please ask if you need login credentials. Also available from the same author for free is [http://svgnest.com/| SVGNest, which can be used by clicking here].

=== Text Cutting ===

In Inkscape, after converting the text object to a path, it's necessary to ungroup the text as well, to create separate paths, prior to flattening the bezier curves.

If you're using a cursive font and want everything to be one piece, convert the text object to a path, and use Path > Union. This tool in general is quite useful for merging paths that have been independently drawn but need to be merged into a single path. For example, if you made two overlapping circles, without this the cutter would just cut the two circles, which leads to a lemon-shaped piece in the center. If you union the paths, it will cut an outline as well. Path > Union will not make any holes in the figure go away, it only gets rid of cuts passing through area covered by another shape.

Engraved text requires no other special technique because no cuts are made, but text cutting is non-trivial. Because of loops, it's sometimes desirable to use a stencil font, especially at smaller scales where legibility is important. 1001 Fonts has a number of stencil fonts for free. At 10pt, some good fonts are Marsh, Spacedock, and Allerta.

== Troubleshooting ==

=== File doesn't appear in laser cutter after successful download ===
If the laser cutter has 99 files loaded into it, new files will not show up. To fix this, open up RDWorks8, and on the right side, select the Doc tab. Inside that tab, click Read to read all the files in the laser cutter, and then click Delete all.
[[Image:laser_cutter_read_files.png|thumb|right|upright=3|alt=read files | This is the button used to read stored files from the laser cutter.]] [[Image:laser_cutter_delete_all_files.png|thumb|right|upright=3|alt=delete all files | This is the button used to delete all stored files from the laser cutter to make room for new ones.]]

== Chlorine material test ==

Before you cut any new material you *must* check that it is safe to cut; specifically that it will not produce chlorine gas when it is burned by the cutting laser. Chlorine is extremely dangerous in its gaseous form and so must be avoided at all costs.

To test a new material, you'll need a sample of the material, a small copper rod (about the thickness of a coat hanger), a pliars, and a handheld propane torch. We'll test for the presence of chlorine by burning a sample of the material in a high temperature propane flame and observe the visible emission spectra. Chrlorine produces a bright green light when burned, and so will be very obvious when you're testing your material.

First, turn on the ventilation on the Sparkle Forge. The switch for this is under the sign that says "For Non-Laser Fires Only", and above the non-laser fire extinguisher. Then, light the propane torch and set it to rest upright on a stable surface. Taking the pliar, hold the piece of copper in the blue part of the flame to heat it. As the copper begins to heat sufficiently it'll cause the flame to turn an orange color. A consistent orange color means that the copper has no residue material on its surface and so is clean enough to use as a test. If you observe non-orange flames when you burn the copper you may need to clean in further, either by waiting for the excess material to burn off, or by scrubbing the surface of the copper when it has cooled.

Once the copper is burning, take the hot copper and melt a sample of the new material onto it. For example if you were testing a new form of plastic you can roll the hot copper rod on the material, melting some of it onto the copper rod's surface.

With this done, place the copper rod back into the blue part of the flame. Observe the colors of the emission spectra from the new material burning. If you observe a bright green color, then the material contains chlorine and thus *must not* be burned further. Ventilate your surrounding area to avoid breathing it in. If you observe no green color as you burn your material sample, then the material is likely safe to use with the laser cutter.

Here is a video example by Zach in NYCResistor with a known good and known bad material: https://www.youtube.com/watch?v=D0_4NLmeSTI

|-
| PVC || Contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| Vinyl || Most contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| PVC Foams || Most contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| Foam Core || Usually made with PVC which is harmful as listed above.
|-
| Styrofoam || Can cause flash fires
|-
| Polycarbonate or PETG || Does not cut. TAP plastics sells both this and acrylic. '''Be sure to read your labels when purchasing material'''. Lexan is the trade name for Polycarbonate, while Plexiglass is the trade name for acrylic.
|-
| ABS || Gives off hydrogen cyanide which can kill you and also may damage the laser optics.
|-
| Fiberglass || Contains complex epoxies which will cause fires, chlorine, and cyanide. Also contains glass which will not cut.
|-
| Metals || Cannot be etched by this type of laser. Also is harmful as the reflective surface may cause the laser to be reflected back up to the head, damaging it. If someone claims to be etching metal using this type of laser then they are etching a metal with a plastic coating, anodized surface, or some other etchable surface on top.

== How do I send files to the Laser computer over the internet? ==

Send your files directly to the laser cutter through this URL [https://cloud.disroot.org/s/bFv70wtK9xQuyp3], which is kindly hosted for us by [https://disroot.org/en| Disroot.org] via [https://nextcloud.com/| Nextcloud].

All files are uploaded directly to ''\My Documents\PUT YOUR FILES HERE (IN YOUR OWN FOLDER)\Uploads for Noisebridge Lasercutter\''

Please move any files you upload to your own folder asap.

== Ok, I created a folder for my laser cutter files, but can I access them over the internet? ==
Yes, this is now possible as of 01/2018.

# Double check you made a folder inside ''\My Documents\PUT YOUR FILES HERE (IN YOUR OWN FOLDER)\''
# Ping @James on Slack with the name of your folder.
# Be sure to mention if you need a password added to your folder.
# Wait a day for the share link to be activated and sent to you.

== Troubleshooting ==

=== Help! All the menu options turned to gibberish! ===
The RDWorks software can be buggy. Go to the top menu, the right-most or or 2nd-right-most tab will have a Language option. Select English.
When that happens, the bed size settings might also have changed. Double check Config -> Document Settings (?). The proper settings are 1300mm × 900mm.
(TODO: need to double check the exact menu labels, doing this from memory at the moment)

=== SOLIDWORKS ===
Apparently DXFs exported from Solidworks (at least v 2017) break when directly imported into RDWorks. The workaround is to import the DXF into Inkscape and re-export it from there.

== How to get trained to use the laser cutter ==

# Ask a trainer if they will train you
# Schedule a time with the trainer
## The laser training class size is limited to 5 students, so that everyone can see how to operate the laser.
# Get trained
# Get your name on the list of users before the first time you use the machine

The laser training class is pay-what-you-can, and the recommended minimum donation is $20.

== Basic Safety ==
The laser cutter is generally a very safe machine to use. However, as with all industrial machines, you need to treat it with respect. The main safety concerns are creating fires, hurting your eyes or skin, getting crushed by the machine, and creating toxic fumes.

The basics:
* ALWAYS MONITOR THE LASER BEAM CUTTING YOUR WORK!
* DO NOT STARE DIRECTLY BECAUSE BURN-GENERATED VISIBLE LIGHT IS VERY BRIGHT!
* USE YOUR PERIPHERAL VISION!
* OPEN THE LID if you see a fire
* BLOW IT OUT if the fire keeps burning
* DON'T CUT UNAPPROVED MATERIALS!
* MAKE SURE THE WINDOWS BY THE BATHROOM ARE CLOSED SO YOU DON'T FUMIGATE NOISEBRIDGE

=== Fire ===

[[Image:Laser_water_estop.jpg|thumb|right|upright=3|alt=Laser cutter with water and estop| The water squirt bottle is sitting on top of the laser, and the estop is the round red button.]]

You can really hurt yourself or burn the building down with this machine. If you follow the safety rules, the chances of you causing this is close to zero. Some materials are very flammable on the laser cutter, and shouldn't be cut. Never cut an unapproved material, or a material you can't identify. A laser beam can also initiate a fire if the speed of the cut is too slow or the laser power is set too high.

Ways to not cause fires:
* ALWAYS MONITOR THE LASER CUTTER WHENEVER IT IS CUTTING AS FIRES CAN HAPPEN. The laser affects your material by heating it. Your job can change in seconds with the accumulation of heat in your material. Never leave the room while the laser is in operation. If you leave the laser unattended, your access to the laser cutter will be permanently revoked.
* Use reasonable speed/power settings. Start with the recommended speed/power settings for your material. Be patient - resist the temptation to crank the power and speed to rush through your job. This can cause fires.
** There will be some light when material is cut. This light at the point of lasing may be ok as long as it stays with the motion of the laser. If a flame appears while the laser is in operation, stop your job and try again with lower heat settings.
* Know where the fire extinguisher is in case of a fire. The ONLY fire extinguisher that should be used on the laser cutter is the halotron extinguisher right next to the laser cutter. Other fire extinguishers are corrosive and will ruin the machine.

How to put out a fire:
* Push the estop. (To turn the machine back on after the estop was hit, you need to switch the power switch on the right hand side of the machine off and on again).
* Open the lid.
* If it's small, try and blow it out.
* If it's smallish, try and squirt it out with the water squirt bottle sitting on the right hand side of the machine.
* If that doesn't work, use the halotron fire extinguisher to the right of the laser cutter. Aim it at the base of the flame.

=== Damage to eyes and skin ===
The laser beam can instantly and permanently blind you. It can also burn your skin.
* The lid's window will block the infrared laser beam, but it doesn't block the visible light produced by the burn. THE VISIBLE LIGHT CAN BE BRIGHT ENOUGH TO DAMAGE YOUR RETINA! DO NOT STARE DIRECTLY AT THE CUT! Use your peripheral vision.
* You don't ever want any part of your body in contact with the beam.
* As long as the door is closed, you're safe to look at the laser. There are interlocks on the door that help ensure the laser never operates with the doors open. Don't disable them.

=== Crushing danger ===

The laser cutter is a dumb machine. It doesn't care whether your hand is in the way when it's moving. The head can move when the door is open. Always make sure everyone's hands are out of the machine before moving the head.

Also be very careful not to crash the head into other parts of the machine. Be very careful when moving the z-axis to not crash the head into the bed, and to not move the z-axis if the focus length acrylic circle is under the lens.

If you need something to weigh down your material, use the magnetic balls or beanbags that are kept near the laser; nothing else. Do not let the laser head crash into these; if it does immediately stop the job.

Be *very* careful to not put the beanbags (or any other material) in such a situation where they may be dragged by the head. The head should never bump into anything, and *especially* never drag anything.

=== Fumes ===
The laser cutter burns the things it's cutting, which can create toxic fumes.
* ONLY CUT APPROVED MATERIALS. Cutting nonapproved materials can release really toxic gases, including chlorine and cyanide. These are really bad for humans, as well as being very damaging to the laser cutter.
* The ventilation fan should always be running if the laser cutter is on, even if it's not cutting. It's currently wired such that you can't turn on the laser cutter without the fan turning on, but please make sure it's running.

== Care of the machine ==

'''Please don't perform any maintenance on the machine (including cleaning lenses/mirrors or aligning mirrors) unless you've specifically trained on it.'''

The laser cutter is finely calibrated piece of machinery. Please close the lid gently, and do not push or jar the machine at any time. Do not lean or press on the tray - it's fragile, and needs to be perfectly flat for the laser cutter to cut properly. If you take the honeycomb bed or slats out, please be ULTRA CAREFUL with them - put them somewhere where they won't get damaged or warped.

== Paying for your laser time ==

The laser cutter has parts that wear out over time, which can be quite costly to replace, especially the laser tube. A new tube costs several thousand dollars. Thus, we require people to pay for the time on the laser they use, so we can pay for new parts. The cost for using the laser cutter is $5 per hour of cutting time.

To figure out how much time your job takes, press the File button, select your file, and then select Work Time from the menu. It will tell you in hours:minutes.seconds.

There is a laser cutter donation box on the wall of the Sparkle Forge room. Please pay for the cutting time you actually use, even if you end up running your job multiple times.

== Workflows ==

=== Overall Workflow ===

This is the overall structure of the workflow. Each part is elaborated below.

# Laser start up
# Material setup
# Convert file to DXF
# Load file onto the machine
# Dry run
# Cut/Engrave
# Laser shut down
# Cleanup

=== Laser start up ===

[[Image:Laser_chiller.jpg|thumb|right|upright=3|alt=Laser chiller| The laser chiller is the box on the bottom left of this photograph. If the laser doesn't beep when it turns on, you should turn on the chiller manually.]]

# Turn on power and ensure that the fan and chiller are running. If you do not hear beeps when the laser starts up, the chiller is not running and you must turn it on.
# Move the head as far forward and right as possible, close to the controls

=== Material setup ===

# Clean the bed of any scraps that may be on it
# Move the cut head as far forward and right as possible (near the controls)
# Raise the laser head as far up as possible
# Raise the bed to the desired height, watching the laser head to avoid crashes
# Move the laser head as far back and right as possible
# Place material on the bed
# Focus the laser (do at least for each distinct thickness, optimally do for each piece of material)

=== Focusing the laser ===

[[Image:Laser_shelf.jpg|thumb|right|upright=3|alt=Shelf by laser cutter | This is the shelf to the left of the laser cutter. The acrylic disks used for focusing the laser are in the toolbox with the yellow lid.]]

Noisebridge has acryllic disks cut to various thicknesses that can be used to accurately focus the laser. Specifically the laser head needs to be locked to 8mm above the surface of the material you're cutting.

# Place the material on the cut bed
# Move the cut head to the center of the area to cut, watching the laser head to avoid crashes w/ material
## Note that the honeycomb bed can move up and down (Z-axis) so if the material doesn't fit under, hit Z/U on the laser controls and navigate the menu until Z axis (or something similar) is selected. Then use the left and right arrows to move the bed up and down.
# Loosen the wing nut and raise the head all the way up
# Place the focusing discs on the material under the head
# Lower the head until it just touches the focusing disc (8mm above material)
# Lock the head in place (tighten the wing nut)
# Remove the focusing discs

=== Convert an image in Inkscape to a DXF file ===

# Load the image into Inkscape
# Set the different cut paths to different colors (for controlling settings, etc.)
# Perform any debugging steps (by default you should perform all of them b/c of errors in the laser software)
# Save as a DXF. Be sure to make the units be millimeters so that importing later will correctly scale the image.

=== Debugging DXF Problems ===

Sometimes exporting to DXF introduces bizarre extra lines. There are two things to try to debug. The first is to convert objects to paths:

# Select all the problematic shapes
# Path > Object to Path

If this fails to resolve the issue, you can try a more radical solution which will eliminate all bezier paths entirely:

# Select all the problematic shapes
# Convert bezier paths to lines (Extensions > Modify Path > Flatten Bezier).

Flatness 0.5 is good to start with. Smaller = better approximation of the curves. A lower flatness number takes more time to compute, but also produces a better approximation to the curve. Be sure to ungroup (sometimes multiple times) before trying this, as grouped objects cannot be flattened as a group. This is especially important for text which is by default a group (each character being a separate object in Inkscape once you've turned it into a path).

Sometimes need to select the path's directly with the path tool (but not the points!).

Also see http://www.pstoedit.net/ for conversion from svg to dxf files.

=== Loading into the laser cutter software ===

# Import the file with File > Import
# Resize as needed, tho if the file was exported w/ millimeter units, the software should also import the image with the correct size.
# Set the cut order:
##* EITHER Set the cut order to inside-out (Handle > Cut optimize > Inside to outside)
##* OR Manually specify cut order with the Set cut property tool (Edit > Set cutting property). See below for more details.
# Set the speed and power for the layers as necessary, and the process mode for each layer to either cut (for continuous line cutting) or dot (for dashed line cutting) or scan (for engraving)
# Optionally, simulate the cutting/engraving process.
# Download to the machine (Laser Work panel on the bottom right).

=== Manually specifying cut order ===

In the Set cutting property window (Edit > Set cutting property), you can manually re-order the cut paths. In the window, you'll see an image of the workpiece, and to its right, two lists of paths. When you first open the window, all of the cut paths are in the left. If you select a path (either in the image or in the list) and click the button labeled ">>", this path will be transferred to the end of the right list of paths. If you click ">>>", all of the paths in the left list will be moved to the end of the right list (preserving order). Similarly, clicking "<<<" will move the right list to the end of the left list. If you select a cut path in the right list, the up and down arrow buttons will reorder that path in the chosen direction.

=== Loading speed and power settings from library ===

# In the top right panel, double click the layer of interest
# Click "Load parameters from library"
# Select the library item
# Click "Load"

=== Saving power and speed settings to library ===

# In the top right panel, double click the layer of interest
# Make sure the layer is set to the desired parameters
# Click "Load parameters from library"
# Click "Save as"
# Enter a name and optionally some notes
# Click "Ok"

=== Simulation ===

# Open the simulation window with either Edit > Preview or the toolbar button labelled with a monitor.
# Click the Simulation button in the right panel

=== Cutting ===

# Select the file to use using the File button
# Move the head to the initial guess origin with the arrow buttons
# Test the frame with the Frame button adjust origin as necessary
# Set the origin by pressing Origin
# Test the cut by turning the laser power off and pressing the Start/Pause button
# Turn the laser power on
# Cut by pressing the Start/Pause button
# It is generally a good idea to put the laser head into one of the top corners and resetting origin before opening the laser if you plan on adding new material to avoid collisions with a moving head.

=== Engraving ===

In the laser software, open the layers you wish to engrave in the layer parameters panel, and send the processing mode to "Scan". This will do a raster scan of the region bounded by the paths in that layer. An even-odd rule is used to assign regions to the "inside" vs "outside" of the engraving.

=== Cancel a cut/dry run ===

# Pause with the Start/Pause button
# Cancel and move back to the origin with the Esc button

=== Laser shut down ===

# Move the head as far forward and right as possible (near the controls)
# Raise the laser head as far up as possible
# Set origin with the origin button (this helps avoid the laser swinging across the bed later)
# Let the fan run for a little bit (~30 seconds)
# Turn the power off

=== Cleanup ===

[[Image:Laser_tray.jpg|thumb|right|upright=3|alt=Laser bottom tray| This is the bottom tray of the laser, which should be cleaned out after use.]]

# Remove pieces of material scrap left on the bed
# Open the tray door on the front bottom and empty the scraps left there

=== Calculating work time ===

On the computer:

* Open the simulation window (see above). Total work time and time of laser use are displayed in the top right. Donations should be calculated by laser use, not total work time.

On the machine:

* Whole file: File > Select file > Right Arrow > Work Time > Enter
* Current run: Pause the cut, then check time at the bottom right

== Fusion 360 ==
Fusion 360 is a free CAD (Computer Aided Design) program from Autodesk for designing 3D parts, and arguably the best one currently available. If you're designing something complex on the laser cutter, particularly with multiple parts that need to fit together, I highly recommend it over drawing programs like Inkscape. It also has CAM (Computer Aided Manufacturing) capabilities, which makes it very useful for CNC machining and laser cutting. There's a copy of the software on the laser cutter computer, and you can download it [http://www.autodesk.com/products/fusion-360/overview here]. It's free as long as you make less than $100k per year using it.

=== Workflow 1: The Quick and Dirty Way ===
This is the fastest way, and works a lot of the time
# Make sure your sketch only contains straight lines, arcs, and circles, and no spline curves. If your sketch has splines, go to [[#Workflow 3: The Long Way]]
# Make sure your part is designed using a single sketch, and that you want to cut all the lines in that sketch. If not, go to [[#Workflow 2: The Middle Ground]]
# Right click on your sketch and click Save As DXF
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]

=== Workflow 2: The Middle Ground ===
If you're not sure, this is probably where you should start.
# Make sure your sketch only contains straight lines, arcs, and circles, and no spline curves. If your sketch has splines, go to [[#Workflow 3: The Long Way]]
# Right click on the top surface of the part you want to cut, and click Create Sketch
# Hit the P key to open the Project dialog box, then select the top surface of your part, and any other lines you want to cut
# Hit OK, then remove any lines you don't want cut
# Open the Sketches folder near the top of the tree, then right click your new sketch and click Save As DXF
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]

=== Workflow 3: The Long Way ===
This allows more complicated things like exporting splines, which doesn't work with the above methods, kerf compensation, which makes your parts fit together snugly, but you can also use the above methods and then do it in RDWorks, or lead-ins and lead-outs, which can make for a cleaner cut, but I can't figure out how to get RDWorks to import correctly.
# Design a part to be laser cut by drawing a 2D sketch and extruding it
# Go to the CAM workspace by clicking the Model button in the top left, then selecting CAM
# Select the Waterjet operation (if you don't see this, turn it on under Preferences -> Preview)
## Set Type to Laser Cutting
## Select the Cutting Mode, either Through - Auto or Etch
## Look up the kerf of the material you're cutting in the [[#Known good materials]] section, and enter that in Kerf Width, or if your material's not listed, cut one a [http://www.thingiverse.com/thing:1166680 kerf gauge] and put the result in the wiki. The kerf changes depending on the thickness, speed and power. Setting a larger kerf width will make your parts fit tighter, and setting a smaller kerf will make them looser.
## Select the contours of your part that you want to cut
## Go to the Passes tab, and change Compensation Type to In Computer
## Hit OK to close the dialog box, and you can see a preview of your tool path. You can go back to edit it by double clicking the contour operation in the tree on the left
# To export to DXF, click the Post Process button, which says G1 G2. Make sure rdworkslaser is selected as your post processor, type a name for the export and hit Post. Then select the folder to put it in.
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]
# Fusion automatically orders the cuts from inside out and in the fastest order, but RDWorks doesn't always respect that order, so you may need to optimize the cut order again

=== Advanced Options ===
# If you're using your own computer for the first time and not the laser cutter desktop, you have to enable the laser cutter support which is still in beta, by clicking on your name in the top right, then Preferences, Preview, and checking "CAM - Waterjet/Laser/Plasma cutter support". You will also need to download the custom post processor that we use for this laser.
# There's a simulate button to the left of the Post Process button, if you want to do it in Fusion
# If you want to disable or tweak the lead ins and lead outs, you can go to the Linking tab. Lead ins and lead outs can fix the bump you get on the side of your part where the laser started and stopped, but they also make extra cuts in your scrap material, which you may want to keep. In this tab you can also specify the Entry Position for each cut path.
# You can disable Kerf Compensation by settting Sideways Compensation to Center under the Passes tab, though this is not recommended

== Techniques ==

=== Kerf Compensation ===

For any given layer, you can compensate for the kerf (width of the cut) by opening it's settings and clicking the "Advance" button next to the "Seal" input box towards the middle-bottom. Enable sew compensation, and pick the direction and sew width (kerf size). The inward direction will make the actual cut move toward the inside of a closed cut path, outward will move it towards the outside.

In general, for cuts on the outside, you want to move outward, to move the actual cut edge be exactly where the path is in your design. For cuts on the inside, you want to use the inward direction.

=== Negative Space Engraving ===

You can engrave a vector shape with a hole in the middle of it, so that you get enclosed portions that are not engraved in the middle of fully engraved portions. To do this, when you construct the image in your editor of choice, simply perform subtraction between the relevant paths, to remove the inner part. In the RDWorks laser software, the two paths will show up, and be independently editable (making them look like just two distinct paths to engrave), but they will engrave correctly as a negative space. Obviously test this w/ your software; this technique is known to work using Inkscape.

=== Nest & Waste Less Material ===

As of 01/2018 you can use the industrial strength [http://deepnest.io/#quickstart Deepnest] installed on the [[Kaitian_CM1309|Laser Cutter computer]] + [[CollaborationStation|Collaboration Station]] in Hackitorium. We have an unlimited subscription available to laser users, which is compatible with both ''DXF'', ''Corel CDR'' and ''SVG'' formats. Please ask if you need login credentials. Also available from the same author for free is [http://svgnest.com/| SVGNest, which can be used by clicking here].

=== Text Cutting ===

In Inkscape, after converting the text object to a path, it's necessary to ungroup the text as well, to create separate paths, prior to flattening the bezier curves.

If you're using a cursive font and want everything to be one piece, convert the text object to a path, and use Path > Union. This tool in general is quite useful for merging paths that have been independently drawn but need to be merged into a single path. For example, if you made two overlapping circles, without this the cutter would just cut the two circles, which leads to a lemon-shaped piece in the center. If you union the paths, it will cut an outline as well. Path > Union will not make any holes in the figure go away, it only gets rid of cuts passing through area covered by another shape.

Engraved text requires no other special technique because no cuts are made, but text cutting is non-trivial. Because of loops, it's sometimes desirable to use a stencil font, especially at smaller scales where legibility is important. 1001 Fonts has a number of stencil fonts for free. At 10pt, some good fonts are Marsh, Spacedock, and Allerta.

== Troubleshooting ==

=== File doesn't appear in laser cutter after successful download ===
If the laser cutter has 99 files loaded into it, new files will not show up. To fix this, open up RDWorks8, and on the right side, select the Doc tab. Inside that tab, click Read to read all the files in the laser cutter, and then click Delete all.
[[Image:laser_cutter_read_files.png|thumb|right|upright=3|alt=read files | This is the button used to read stored files from the laser cutter.]] [[Image:laser_cutter_delete_all_files.png|thumb|right|upright=3|alt=delete all files | This is the button used to delete all stored files from the laser cutter to make room for new ones.]]

== Chlorine material test ==

Before you cut any new material you *must* check that it is safe to cut; specifically that it will not produce chlorine gas when it is burned by the cutting laser. Chlorine is extremely dangerous in its gaseous form and so must be avoided at all costs.

To test a new material, you'll need a sample of the material, a small copper rod (about the thickness of a coat hanger), a pliars, and a handheld propane torch. We'll test for the presence of chlorine by burning a sample of the material in a high temperature propane flame and observe the visible emission spectra. Chrlorine produces a bright green light when burned, and so will be very obvious when you're testing your material.

First, turn on the ventilation on the Sparkle Forge. The switch for this is under the sign that says "For Non-Laser Fires Only", and above the non-laser fire extinguisher. Then, light the propane torch and set it to rest upright on a stable surface. Taking the pliar, hold the piece of copper in the blue part of the flame to heat it. As the copper begins to heat sufficiently it'll cause the flame to turn an orange color. A consistent orange color means that the copper has no residue material on its surface and so is clean enough to use as a test. If you observe non-orange flames when you burn the copper you may need to clean in further, either by waiting for the excess material to burn off, or by scrubbing the surface of the copper when it has cooled.

Once the copper is burning, take the hot copper and melt a sample of the new material onto it. For example if you were testing a new form of plastic you can roll the hot copper rod on the material, melting some of it onto the copper rod's surface.

With this done, place the copper rod back into the blue part of the flame. Observe the colors of the emission spectra from the new material burning. If you observe a bright green color, then the material contains chlorine and thus *must not* be burned further. Ventilate your surrounding area to avoid breathing it in. If you observe no green color as you burn your material sample, then the material is likely safe to use with the laser cutter.

Here is a video example by Zach in NYCResistor with a known good and known bad material: https://www.youtube.com/watch?v=D0_4NLmeSTI

== BANNED MATERIALS (NEVER USE THESE) ==

These materials '''must not be used in the laser cutter'''.

|-
| PVC || Contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| Vinyl || Most contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| PVC Foams || Most contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| Foam Core || Usually made with PVC which is harmful as listed above.
|-
| Styrofoam || Can cause flash fires
|-
| Polycarbonate or PETG || Does not cut. TAP plastics sells both this and acrylic. '''Be sure to read your labels when purchasing material'''. Lexan is the trade name for Polycarbonate, while Plexiglass is the trade name for acrylic.
|-
| ABS || Gives off hydrogen cyanide which can kill you and also may damage the laser optics.
|-
| Fiberglass || Contains complex epoxies which will cause fires, chlorine, and cyanide. Also contains glass which will not cut.
|-
| Metals || Cannot be etched by this type of laser. Also is harmful as the reflective surface may cause the laser to be reflected back up to the head, damaging it. If someone claims to be etching metal using this type of laser then they are etching a metal with a plastic coating, anodized surface, or some other etchable surface on top.

== How do I send files to the Laser computer over the internet? ==

Send your files directly to the laser cutter through this URL [https://cloud.disroot.org/s/bFv70wtK9xQuyp3], which is kindly hosted for us by [https://disroot.org/en| Disroot.org] via [https://nextcloud.com/| Nextcloud].

All files are uploaded directly to ''\My Documents\PUT YOUR FILES HERE (IN YOUR OWN FOLDER)\Uploads for Noisebridge Lasercutter\''

Please move any files you upload to your own folder asap.

== Ok, I created a folder for my laser cutter files, but can I access them over the internet? ==
Yes, this is now possible as of 01/2018.

# Double check you made a folder inside ''\My Documents\PUT YOUR FILES HERE (IN YOUR OWN FOLDER)\''
# Ping @James on Slack with the name of your folder.
# Be sure to mention if you need a password added to your folder.
# Wait a day for the share link to be activated and sent to you.

== Troubleshooting ==

=== Help! All the menu options turned to gibberish! ===
The RDWorks software can be buggy. Go to the top menu, the right-most or or 2nd-right-most tab will have a Language option. Select English.
When that happens, the bed size settings might also have changed. Double check Config -> Document Settings (?). The proper settings are 1300mm × 900mm.
(TODO: need to double check the exact menu labels, doing this from memory at the moment)

=== SOLIDWORKS ===
Apparently DXFs exported from Solidworks (at least v 2017) break when directly imported into RDWorks. The workaround is to import the DXF into Inkscape and re-export it from there.

== How to get trained to use the laser cutter ==

# Ask a trainer if they will train you
# Schedule a time with the trainer
## The laser training class size is limited to 5 students, so that everyone can see how to operate the laser.
# Get trained
# Get your name on the list of users before the first time you use the machine

The laser training class is pay-what-you-can, and the recommended minimum donation is $20.

== Basic Safety ==
The laser cutter is generally a very safe machine to use. However, as with all industrial machines, you need to treat it with respect. The main safety concerns are creating fires, hurting your eyes or skin, getting crushed by the machine, and creating toxic fumes.

The basics:
* ALWAYS MONITOR THE LASER BEAM CUTTING YOUR WORK!
* DO NOT STARE DIRECTLY BECAUSE BURN-GENERATED VISIBLE LIGHT IS VERY BRIGHT!
* USE YOUR PERIPHERAL VISION!
* OPEN THE LID if you see a fire
* BLOW IT OUT if the fire keeps burning
* DON'T CUT UNAPPROVED MATERIALS!
* MAKE SURE THE WINDOWS BY THE BATHROOM ARE CLOSED SO YOU DON'T FUMIGATE NOISEBRIDGE

=== Fire ===

[[Image:Laser_water_estop.jpg|thumb|right|upright=3|alt=Laser cutter with water and estop| The water squirt bottle is sitting on top of the laser, and the estop is the round red button.]]

You can really hurt yourself or burn the building down with this machine. If you follow the safety rules, the chances of you causing this is close to zero. Some materials are very flammable on the laser cutter, and shouldn't be cut. Never cut an unapproved material, or a material you can't identify. A laser beam can also initiate a fire if the speed of the cut is too slow or the laser power is set too high.

Ways to not cause fires:
* ALWAYS MONITOR THE LASER CUTTER WHENEVER IT IS CUTTING AS FIRES CAN HAPPEN. The laser affects your material by heating it. Your job can change in seconds with the accumulation of heat in your material. Never leave the room while the laser is in operation. If you leave the laser unattended, your access to the laser cutter will be permanently revoked.
* Use reasonable speed/power settings. Start with the recommended speed/power settings for your material. Be patient - resist the temptation to crank the power and speed to rush through your job. This can cause fires.
** There will be some light when material is cut. This light at the point of lasing may be ok as long as it stays with the motion of the laser. If a flame appears while the laser is in operation, stop your job and try again with lower heat settings.
* Know where the fire extinguisher is in case of a fire. The ONLY fire extinguisher that should be used on the laser cutter is the halotron extinguisher right next to the laser cutter. Other fire extinguishers are corrosive and will ruin the machine.

How to put out a fire:
* Push the estop. (To turn the machine back on after the estop was hit, you need to switch the power switch on the right hand side of the machine off and on again).
* Open the lid.
* If it's small, try and blow it out.
* If it's smallish, try and squirt it out with the water squirt bottle sitting on the right hand side of the machine.
* If that doesn't work, use the halotron fire extinguisher to the right of the laser cutter. Aim it at the base of the flame.

=== Damage to eyes and skin ===
The laser beam can instantly and permanently blind you. It can also burn your skin.
* The lid's window will block the infrared laser beam, but it doesn't block the visible light produced by the burn. THE VISIBLE LIGHT CAN BE BRIGHT ENOUGH TO DAMAGE YOUR RETINA! DO NOT STARE DIRECTLY AT THE CUT! Use your peripheral vision.
* You don't ever want any part of your body in contact with the beam.
* As long as the door is closed, you're safe to look at the laser. There are interlocks on the door that help ensure the laser never operates with the doors open. Don't disable them.

=== Crushing danger ===

The laser cutter is a dumb machine. It doesn't care whether your hand is in the way when it's moving. The head can move when the door is open. Always make sure everyone's hands are out of the machine before moving the head.

Also be very careful not to crash the head into other parts of the machine. Be very careful when moving the z-axis to not crash the head into the bed, and to not move the z-axis if the focus length acrylic circle is under the lens.

If you need something to weigh down your material, use the magnetic balls or beanbags that are kept near the laser; nothing else. Do not let the laser head crash into these; if it does immediately stop the job.

Be *very* careful to not put the beanbags (or any other material) in such a situation where they may be dragged by the head. The head should never bump into anything, and *especially* never drag anything.

=== Fumes ===
The laser cutter burns the things it's cutting, which can create toxic fumes.
* ONLY CUT APPROVED MATERIALS. Cutting nonapproved materials can release really toxic gases, including chlorine and cyanide. These are really bad for humans, as well as being very damaging to the laser cutter.
* The ventilation fan should always be running if the laser cutter is on, even if it's not cutting. It's currently wired such that you can't turn on the laser cutter without the fan turning on, but please make sure it's running.

== Care of the machine ==

'''Please don't perform any maintenance on the machine (including cleaning lenses/mirrors or aligning mirrors) unless you've specifically trained on it.'''

The laser cutter is finely calibrated piece of machinery. Please close the lid gently, and do not push or jar the machine at any time. Do not lean or press on the tray - it's fragile, and needs to be perfectly flat for the laser cutter to cut properly. If you take the honeycomb bed or slats out, please be ULTRA CAREFUL with them - put them somewhere where they won't get damaged or warped.

== Paying for your laser time ==

The laser cutter has parts that wear out over time, which can be quite costly to replace, especially the laser tube. A new tube costs several thousand dollars. Thus, we require people to pay for the time on the laser they use, so we can pay for new parts. The cost for using the laser cutter is $5 per hour of cutting time.

To figure out how much time your job takes, press the File button, select your file, and then select Work Time from the menu. It will tell you in hours:minutes.seconds.

There is a laser cutter donation box on the wall of the Sparkle Forge room. Please pay for the cutting time you actually use, even if you end up running your job multiple times.

== Workflows ==

=== Overall Workflow ===

This is the overall structure of the workflow. Each part is elaborated below.

# Laser start up
# Material setup
# Convert file to DXF
# Load file onto the machine
# Dry run
# Cut/Engrave
# Laser shut down
# Cleanup

=== Laser start up ===

[[Image:Laser_chiller.jpg|thumb|right|upright=3|alt=Laser chiller| The laser chiller is the box on the bottom left of this photograph. If the laser doesn't beep when it turns on, you should turn on the chiller manually.]]

# Turn on power and ensure that the fan and chiller are running. If you do not hear beeps when the laser starts up, the chiller is not running and you must turn it on.
# Move the head as far forward and right as possible, close to the controls

=== Material setup ===

# Clean the bed of any scraps that may be on it
# Move the cut head as far forward and right as possible (near the controls)
# Raise the laser head as far up as possible
# Raise the bed to the desired height, watching the laser head to avoid crashes
# Move the laser head as far back and right as possible
# Place material on the bed
# Focus the laser (do at least for each distinct thickness, optimally do for each piece of material)

=== Focusing the laser ===

[[Image:Laser_shelf.jpg|thumb|right|upright=3|alt=Shelf by laser cutter | This is the shelf to the left of the laser cutter. The acrylic disks used for focusing the laser are in the toolbox with the yellow lid.]]

Noisebridge has acryllic disks cut to various thicknesses that can be used to accurately focus the laser. Specifically the laser head needs to be locked to 8mm above the surface of the material you're cutting.

# Place the material on the cut bed
# Move the cut head to the center of the area to cut, watching the laser head to avoid crashes w/ material
## Note that the honeycomb bed can move up and down (Z-axis) so if the material doesn't fit under, hit Z/U on the laser controls and navigate the menu until Z axis (or something similar) is selected. Then use the left and right arrows to move the bed up and down.
# Loosen the wing nut and raise the head all the way up
# Place the focusing discs on the material under the head
# Lower the head until it just touches the focusing disc (8mm above material)
# Lock the head in place (tighten the wing nut)
# Remove the focusing discs

=== Convert an image in Inkscape to a DXF file ===

# Load the image into Inkscape
# Set the different cut paths to different colors (for controlling settings, etc.)
# Perform any debugging steps (by default you should perform all of them b/c of errors in the laser software)
# Save as a DXF. Be sure to make the units be millimeters so that importing later will correctly scale the image.

=== Debugging DXF Problems ===

Sometimes exporting to DXF introduces bizarre extra lines. There are two things to try to debug. The first is to convert objects to paths:

# Select all the problematic shapes
# Path > Object to Path

If this fails to resolve the issue, you can try a more radical solution which will eliminate all bezier paths entirely:

# Select all the problematic shapes
# Convert bezier paths to lines (Extensions > Modify Path > Flatten Bezier).

Flatness 0.5 is good to start with. Smaller = better approximation of the curves. A lower flatness number takes more time to compute, but also produces a better approximation to the curve. Be sure to ungroup (sometimes multiple times) before trying this, as grouped objects cannot be flattened as a group. This is especially important for text which is by default a group (each character being a separate object in Inkscape once you've turned it into a path).

Sometimes need to select the path's directly with the path tool (but not the points!).

=== Loading into the laser cutter software ===

# Import the file with File > Import
# Resize as needed, tho if the file was exported w/ millimeter units, the software should also import the image with the correct size.
# Set the cut order:
##* EITHER Set the cut order to inside-out (Handle > Cut optimize > Inside to outside)
##* OR Manually specify cut order with the Set cut property tool (Edit > Set cutting property). See below for more details.
# Set the speed and power for the layers as necessary, and the process mode for each layer to either cut (for continuous line cutting) or dot (for dashed line cutting) or scan (for engraving)
# Optionally, simulate the cutting/engraving process.
# Download to the machine (Laser Work panel on the bottom right).

=== Manually specifying cut order ===

In the Set cutting property window (Edit > Set cutting property), you can manually re-order the cut paths. In the window, you'll see an image of the workpiece, and to its right, two lists of paths. When you first open the window, all of the cut paths are in the left. If you select a path (either in the image or in the list) and click the button labeled ">>", this path will be transferred to the end of the right list of paths. If you click ">>>", all of the paths in the left list will be moved to the end of the right list (preserving order). Similarly, clicking "<<<" will move the right list to the end of the left list. If you select a cut path in the right list, the up and down arrow buttons will reorder that path in the chosen direction.

=== Loading speed and power settings from library ===

# In the top right panel, double click the layer of interest
# Click "Load parameters from library"
# Select the library item
# Click "Load"

=== Saving power and speed settings to library ===

# In the top right panel, double click the layer of interest
# Make sure the layer is set to the desired parameters
# Click "Load parameters from library"
# Click "Save as"
# Enter a name and optionally some notes
# Click "Ok"

=== Simulation ===

# Open the simulation window with either Edit > Preview or the toolbar button labelled with a monitor.
# Click the Simulation button in the right panel

=== Cutting ===

# Select the file to use using the File button
# Move the head to the initial guess origin with the arrow buttons
# Test the frame with the Frame button adjust origin as necessary
# Set the origin by pressing Origin
# Test the cut by turning the laser power off and pressing the Start/Pause button
# Turn the laser power on
# Cut by pressing the Start/Pause button
# It is generally a good idea to put the laser head into one of the top corners and resetting origin before opening the laser if you plan on adding new material to avoid collisions with a moving head.

=== Engraving ===

In the laser software, open the layers you wish to engrave in the layer parameters panel, and send the processing mode to "Scan". This will do a raster scan of the region bounded by the paths in that layer. An even-odd rule is used to assign regions to the "inside" vs "outside" of the engraving.

=== Cancel a cut/dry run ===

# Pause with the Start/Pause button
# Cancel and move back to the origin with the Esc button

=== Laser shut down ===

# Move the head as far forward and right as possible (near the controls)
# Raise the laser head as far up as possible
# Set origin with the origin button (this helps avoid the laser swinging across the bed later)
# Let the fan run for a little bit (~30 seconds)
# Turn the power off

=== Cleanup ===

[[Image:Laser_tray.jpg|thumb|right|upright=3|alt=Laser bottom tray| This is the bottom tray of the laser, which should be cleaned out after use.]]

# Remove pieces of material scrap left on the bed
# Open the tray door on the front bottom and empty the scraps left there

=== Calculating work time ===

On the computer:

* Open the simulation window (see above). Total work time and time of laser use are displayed in the top right. Donations should be calculated by laser use, not total work time.

On the machine:

* Whole file: File > Select file > Right Arrow > Work Time > Enter
* Current run: Pause the cut, then check time at the bottom right

== Fusion 360 ==
Fusion 360 is a free CAD (Computer Aided Design) program from Autodesk for designing 3D parts, and arguably the best one currently available. If you're designing something complex on the laser cutter, particularly with multiple parts that need to fit together, I highly recommend it over drawing programs like Inkscape. It also has CAM (Computer Aided Manufacturing) capabilities, which makes it very useful for CNC machining and laser cutting. There's a copy of the software on the laser cutter computer, and you can download it [http://www.autodesk.com/products/fusion-360/overview here]. It's free as long as you make less than $100k per year using it.

=== Workflow 1: The Quick and Dirty Way ===
This is the fastest way, and works a lot of the time
# Make sure your sketch only contains straight lines, arcs, and circles, and no spline curves. If your sketch has splines, go to [[#Workflow 3: The Long Way]]
# Make sure your part is designed using a single sketch, and that you want to cut all the lines in that sketch. If not, go to [[#Workflow 2: The Middle Ground]]
# Right click on your sketch and click Save As DXF
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]

=== Workflow 2: The Middle Ground ===
If you're not sure, this is probably where you should start.
# Make sure your sketch only contains straight lines, arcs, and circles, and no spline curves. If your sketch has splines, go to [[#Workflow 3: The Long Way]]
# Right click on the top surface of the part you want to cut, and click Create Sketch
# Hit the P key to open the Project dialog box, then select the top surface of your part, and any other lines you want to cut
# Hit OK, then remove any lines you don't want cut
# Open the Sketches folder near the top of the tree, then right click your new sketch and click Save As DXF
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]

=== Workflow 3: The Long Way ===
This allows more complicated things like exporting splines, which doesn't work with the above methods, kerf compensation, which makes your parts fit together snugly, but you can also use the above methods and then do it in RDWorks, or lead-ins and lead-outs, which can make for a cleaner cut, but I can't figure out how to get RDWorks to import correctly.
# Design a part to be laser cut by drawing a 2D sketch and extruding it
# Go to the CAM workspace by clicking the Model button in the top left, then selecting CAM
# Select the Waterjet operation (if you don't see this, turn it on under Preferences -> Preview)
## Set Type to Laser Cutting
## Select the Cutting Mode, either Through - Auto or Etch
## Look up the kerf of the material you're cutting in the [[#Known good materials]] section, and enter that in Kerf Width, or if your material's not listed, cut one a [http://www.thingiverse.com/thing:1166680 kerf gauge] and put the result in the wiki. The kerf changes depending on the thickness, speed and power. Setting a larger kerf width will make your parts fit tighter, and setting a smaller kerf will make them looser.
## Select the contours of your part that you want to cut
## Go to the Passes tab, and change Compensation Type to In Computer
## Hit OK to close the dialog box, and you can see a preview of your tool path. You can go back to edit it by double clicking the contour operation in the tree on the left
# To export to DXF, click the Post Process button, which says G1 G2. Make sure rdworkslaser is selected as your post processor, type a name for the export and hit Post. Then select the folder to put it in.
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]
# Fusion automatically orders the cuts from inside out and in the fastest order, but RDWorks doesn't always respect that order, so you may need to optimize the cut order again

=== Advanced Options ===
# If you're using your own computer for the first time and not the laser cutter desktop, you have to enable the laser cutter support which is still in beta, by clicking on your name in the top right, then Preferences, Preview, and checking "CAM - Waterjet/Laser/Plasma cutter support". You will also need to download the custom post processor that we use for this laser.
# There's a simulate button to the left of the Post Process button, if you want to do it in Fusion
# If you want to disable or tweak the lead ins and lead outs, you can go to the Linking tab. Lead ins and lead outs can fix the bump you get on the side of your part where the laser started and stopped, but they also make extra cuts in your scrap material, which you may want to keep. In this tab you can also specify the Entry Position for each cut path.
# You can disable Kerf Compensation by settting Sideways Compensation to Center under the Passes tab, though this is not recommended

== Techniques ==

=== Kerf Compensation ===

For any given layer, you can compensate for the kerf (width of the cut) by opening it's settings and clicking the "Advance" button next to the "Seal" input box towards the middle-bottom. Enable sew compensation, and pick the direction and sew width (kerf size). The inward direction will make the actual cut move toward the inside of a closed cut path, outward will move it towards the outside.

In general, for cuts on the outside, you want to move outward, to move the actual cut edge be exactly where the path is in your design. For cuts on the inside, you want to use the inward direction.

=== Negative Space Engraving ===

You can engrave a vector shape with a hole in the middle of it, so that you get enclosed portions that are not engraved in the middle of fully engraved portions. To do this, when you construct the image in your editor of choice, simply perform subtraction between the relevant paths, to remove the inner part. In the RDWorks laser software, the two paths will show up, and be independently editable (making them look like just two distinct paths to engrave), but they will engrave correctly as a negative space. Obviously test this w/ your software; this technique is known to work using Inkscape.

=== Nest & Waste Less Material ===

As of 01/2018 you can use the industrial strength [http://deepnest.io/#quickstart Deepnest] installed on the [[Kaitian_CM1309|Laser Cutter computer]] + [[CollaborationStation|Collaboration Station]] in Hackitorium. We have an unlimited subscription available to laser users, which is compatible with both ''DXF'', ''Corel CDR'' and ''SVG'' formats. Please ask if you need login credentials. Also available from the same author for free is [http://svgnest.com/| SVGNest, which can be used by clicking here].

=== Text Cutting ===

In Inkscape, after converting the text object to a path, it's necessary to ungroup the text as well, to create separate paths, prior to flattening the bezier curves.

If you're using a cursive font and want everything to be one piece, convert the text object to a path, and use Path > Union. This tool in general is quite useful for merging paths that have been independently drawn but need to be merged into a single path. For example, if you made two overlapping circles, without this the cutter would just cut the two circles, which leads to a lemon-shaped piece in the center. If you union the paths, it will cut an outline as well. Path > Union will not make any holes in the figure go away, it only gets rid of cuts passing through area covered by another shape.

Engraved text requires no other special technique because no cuts are made, but text cutting is non-trivial. Because of loops, it's sometimes desirable to use a stencil font, especially at smaller scales where legibility is important. 1001 Fonts has a number of stencil fonts for free. At 10pt, some good fonts are Marsh, Spacedock, and Allerta.

== Troubleshooting ==

=== File doesn't appear in laser cutter after successful download ===
If the laser cutter has 99 files loaded into it, new files will not show up. To fix this, open up RDWorks8, and on the right side, select the Doc tab. Inside that tab, click Read to read all the files in the laser cutter, and then click Delete all.
[[Image:laser_cutter_read_files.png|thumb|right|upright=3|alt=read files | This is the button used to read stored files from the laser cutter.]] [[Image:laser_cutter_delete_all_files.png|thumb|right|upright=3|alt=delete all files | This is the button used to delete all stored files from the laser cutter to make room for new ones.]]

== Chlorine material test ==

Before you cut any new material you *must* check that it is safe to cut; specifically that it will not produce chlorine gas when it is burned by the cutting laser. Chlorine is extremely dangerous in its gaseous form and so must be avoided at all costs.

To test a new material, you'll need a sample of the material, a small copper rod (about the thickness of a coat hanger), a pliars, and a handheld propane torch. We'll test for the presence of chlorine by burning a sample of the material in a high temperature propane flame and observe the visible emission spectra. Chrlorine produces a bright green light when burned, and so will be very obvious when you're testing your material.

First, turn on the ventilation on the Sparkle Forge. The switch for this is under the sign that says "For Non-Laser Fires Only", and above the non-laser fire extinguisher. Then, light the propane torch and set it to rest upright on a stable surface. Taking the pliar, hold the piece of copper in the blue part of the flame to heat it. As the copper begins to heat sufficiently it'll cause the flame to turn an orange color. A consistent orange color means that the copper has no residue material on its surface and so is clean enough to use as a test. If you observe non-orange flames when you burn the copper you may need to clean in further, either by waiting for the excess material to burn off, or by scrubbing the surface of the copper when it has cooled.

Once the copper is burning, take the hot copper and melt a sample of the new material onto it. For example if you were testing a new form of plastic you can roll the hot copper rod on the material, melting some of it onto the copper rod's surface.

With this done, place the copper rod back into the blue part of the flame. Observe the colors of the emission spectra from the new material burning. If you observe a bright green color, then the material contains chlorine and thus *must not* be burned further. Ventilate your surrounding area to avoid breathing it in. If you observe no green color as you burn your material sample, then the material is likely safe to use with the laser cutter.

Here is a video example by Zach in NYCResistor with a known good and known bad material: https://www.youtube.com/watch?v=D0_4NLmeSTI

== BANNED MATERIALS (NEVER USE THESE) ==

These materials '''must not be used in the laser cutter'''.

|-
| PVC || Contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| Vinyl || Most contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| PVC Foams || Most contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| Foam Core || Usually made with PVC which is harmful as listed above.
|-
| Styrofoam || Can cause flash fires
|-
| Polycarbonate or PETG || Does not cut. TAP plastics sells both this and acrylic. '''Be sure to read your labels when purchasing material'''. Lexan is the trade name for Polycarbonate, while Plexiglass is the trade name for acrylic.
|-
| ABS || Gives off hydrogen cyanide which can kill you and also may damage the laser optics.
|-
| Fiberglass || Contains complex epoxies which will cause fires, chlorine, and cyanide. Also contains glass which will not cut.
|-
| Metals || Cannot be etched by this type of laser. Also is harmful as the reflective surface may cause the laser to be reflected back up to the head, damaging it. If someone claims to be etching metal using this type of laser then they are etching a metal with a plastic coating, anodized surface, or some other etchable surface on top.

When cutting a knot in the wood, you'll have to use a lower speed, 9-10 will probably work. This wood was high quality scroll wood with almost no knots.

The [[Laser Gallery]] contains some past projects and cutting tests.

== Sourcing Material ==

In general, you can get stuff from Amazon, but you have to wait for shipping.

For plastics: [http://www.google.com/maps/place/TAP+Plastics/@37.7711648,-122.4207603,17z/data=!3m1!4b1!4m5!3m4!1s0x808f7e27351bb079:0x7e3610d7dc178b10!8m2!3d37.7711648!4d-122.4185663 Tap Plastics] is nearby Noisebridge, but is expensive, [http://eplastics.com eplastics] is cheaper but you need to wait for shipping, and [https://www.google.com/maps/place/Mr.+Plastics/@37.7091519,-122.1546962,17z/data=!3m1!4b1!4m5!3m4!1s0x808f8fe7938349a3:0xafcb2526326faccd!8m2!3d37.7091519!4d-122.1525022 Mr. Plastics] is cheapest but is in San Leandro.

For woods: [http://www.google.com/maps/place/Discount+Builders+Supply/@37.7704879,-122.4191311,15z/data=!4m2!3m1!1s0x0:0x3c0d6c6e25a89652?sa=X&ved=0ahUKEwjV87WU-JzOAhUI6WMKHSPABOUQ_BIIeTAK Discount Builder Supply] is nearby.

== How do I send files to the Laser computer over the internet? ==

Send your files directly to the laser cutter through this URL [https://cloud.disroot.org/s/bFv70wtK9xQuyp3], which is kindly hosted for us by [https://disroot.org/en| Disroot.org] via [https://nextcloud.com/| Nextcloud].

All files are uploaded directly to ''\My Documents\PUT YOUR FILES HERE (IN YOUR OWN FOLDER)\Uploads for Noisebridge Lasercutter\''

Please move any files you upload to your own folder asap.

== Ok, I created a folder for my laser cutter files, but can I access them over the internet? ==
Yes, this is now possible as of 01/2018.

# Double check you made a folder inside ''\My Documents\PUT YOUR FILES HERE (IN YOUR OWN FOLDER)\''
# Ping @James on Slack with the name of your folder.
# Be sure to mention if you need a password added to your folder.
# Wait a day for the share link to be activated and sent to you.

== Troubleshooting ==

=== Help! All the menu options turned to gibberish! ===
The RDWorks software can be buggy. Go to the top menu, the right-most or or 2nd-right-most tab will have a Language option. Select English.
When that happens, the bed size settings might also have changed. Double check Config -> Document Settings (?). The proper settings are 1300mm × 900mm.
(TODO: need to double check the exact menu labels, doing this from memory at the moment)

=== SOLIDWORKS ===
Apparently DXFs exported from Solidworks (at least v 2017) break when directly imported into RDWorks. The workaround is to import the DXF into Inkscape and re-export it from there.

|description = [[HackTheLeft|Hack the Left]] is an ''anticapitalist'' hackathon, going on for the entire long weekend of February 5th-7th at Noisebridge. This is an experiment to see what happens when you get a bunch of leftists in a room for a weekend with the intention to advance liberatory and ''anticapitalist'' projects using technology. This includes software projects like Tor and Signal, art projects like the Anti-Eviction Mapping Project and Men in Grey, hardware projects like mesh networks and signal jammers, and tools for rad organizations like Anti Police-Crimethink Project and Food Not Bombs. It's clear that there's a huge amount of opportunity for liberatory technology. It's up to us to build it.

Mediation

2018-01-04T23:57:28Z

Mcscope: Reverted edits by 199.249.223.46 (talk) to last revision by 🐼

This is a wiki page for a mediation process to help address interpersonal conflicts in and relating to the Noisebridge community.

All relationships take work. This includes community. Community takes work. Occasionally there may be disagreements in any relationship.

The Noisebridge [[Conflict Resolution]] wiki page contains general guidance for people in the community who are experiencing problems. These suggestions might help someone who is trying to decide if they should seek mediation or not.

The first step when there is a disagreement is for the people involved to talk to each other, and, while following Noisebridge's one rule of being excellent to each other, work out the problem(s) together. This tends to clear up almost all disagreements.

If the disagreement can't be worked out together, all persons involved with the disagreement are encouraged to get together with a mediator.

Mediators are people who have volunteered their time to help people who have disagreements, to de-escalate conflict, to seek resolution, and to provide community support and protection for all involved. The ideal mediators should strive to make themselves readily accessible to both conflicting parties, and should also enjoy interacting with others without the need for imposing their own wills over those of the other people involved in the particular conflict.

The role of the mediator is to calmly talk with those involved to help clear up the disagreements they have with one another. If those involved agree, the mediator can help schedule an informal get-together with the parties involved (or act as go-between, if that is more appropriate). It is the mediators role to ensure that all involved feel safe, feel heard, and are able to say their peace. No one should feel attacked during the mediation get-together. More details on this are given below (''please see [[Mediation#Specific_process_for_mediators|Specific process for mediators]]'').

In past years, disagreements between people have been resolved through mediation -- even when it appeared to all those involved that the situation was intractable.

The following people have at some time or another over the last several years volunteered to help mediate conflicts and provide a sounding board and guidance for people who are experiencing troublesome interpersonal interactions.

* [[User:maltman23|Mitch]]
* [[User:bfb|Kevin]]
* [[User:Lxpk|Alex]]
* [[User:Tdfischer|Torrie]]
* [[User:Patrickod|Patrick]]
* [[User:Fineline|Steve]]
* [[User:Tman66|J]]
* [[User:Ruthgrace|Ruth Grace Wong]]

Feel free to contact any of the above people if you would like help in mediating any problems. Also, feel free to ask others to mediate for you, as the above volunteers are not an exclusive list.

Noisebridge operates by anarchic chaos, by do-ocracy, and, like all organizations, through a healthy serving of precedent. There are no rules for how this process should work, but we have some suggestions:

==General process:==
===Mediation:===

Mediators can actively mediate a discussion between the individuals having conflict, or talk to one individual as a proxy for the other.

===Mindfulness towards Escalation:===

If it seems appropriate, after talking with the original parties, the mediator (and indeed everyone involved) should start to tactfully ask around and find out if this is an isolated conflict or a more generalized problem in the community. Most personal problems at Noisebridge can be resolved through a series of calm one-on-one talks, and almost all of the rest can be solved by a series of mediated discussions. If mediation is unsuccessful, or if what is going on appears to be part of a larger pattern, the mediator may suggest calling a meeting of the Safe Space Working Group for discussion.

===Advocate:===

Before a problem with an individual is brought to a Safe Space Working Group, someone must step forward to act as an advocate for the individual, even if that individual happens to be widely disliked. It is all too easy for conflict to prod people into acting in ways that they later regret. There are sufficient people around the Space who are willing to act as advocates (see above list of mediator volunteers on this wiki page).

Discussing personal conflicts at the larger group level is not really considered all that excellent. On the other hand, a small supportive group environment more specifically committed to calm discussion and de-escalation '''can''' help defuse a problematic situation. Mediation and the Safe Space Working Group are resources available for use when needed.

If you try to follow these suggestions, that would be totally excellent.

==Specific process for mediators==

First, talk to the person(s) who asked you to mediate to find out more about the conflict.

Next step is to either calmly discuss the issue with the second party as a proxy or to enter a calm, mediated discussion between the two individuals in conflict.

Mediated discussion between individuals can be casual or very structured, depending on the tenor of the disagreement. One method that works in extreme cases is to sit down with both parties but ask them to only speak to you, not to each other, during the first part of the mediation. This helps each party to feel like their version of events is being heard. After you feel like you have both sides of the story, the conflicting parties should spend some time mirroring each other's feelings - in a structured way, taking turns restating the other person's concerns or position in their own words. Only after this point should the conflicting parties move towards actual dialogue.

At this point, also, it is important that mediators take some time outside of this process to tactfully ask around and find out if this is an isolated conflict or a more generalized problem in the community.

If this mediation is not successful, not embraced by one of the conflicting parties, or is partially successful but the mediator's research indicates that this may be part of a pattern of behavior, the mediator is encouraged to ensure there is an advocate for everyone involved, and to call for a Safe Space Working Group to discuss the issues.

__NOEDITSECTION__[[Image:Noisebridge_soldering.jpg|thumb|right|180px|Learning by doing!]]
[[Image:Evocell_ecoli15.png|thumb|right|180px|Do cool stuff!]]
[[Image:Noisebridge_at_night.jpg|thumb|right|180px|Interact with interesting people!]]
Noisebridge is a space for sharing, creation, collaboration, research, development, mentoring, and of course, learning. Noisebridge is also more than a physical space; it's a community with roots extending around the world.

<blockquote>
For we're excellent to each other here 
We rarely ever block 
We value tools over pre-emptive rules 
And spurn the key and the lock. 
       — Danny O'Brien, 2010-11-09 general meeting notes
</blockquote>

''We make stuff. So can you.''

== The Idea ==

Noisebridge is an educational non-profit corporation, 501(c)3 public charity status.

We provide infrastructure and collaboration opportunities for people interested in programming, hardware hacking, physics, chemistry, mathematics, security, robotics, all kinds of art, and, of course, technology. Through talks, workshops, and [[projects]] we encourage knowledge exchange, learning, and mentoring.

As a space for artistic collaboration and experimentation, we are open to most types of art - with a special emphasis on the crossover of art and technology. From hardware labs to electronics and sound labs, most things that're creative are most definitely welcome.

Many interesting things happen in the space. We've found that sharing is essential to making this work. We strive to begin from a point of respect and trust. We believe it builds a safe community and that this best fosters innovation and creation.
Our motto is "Be excellent to each other." We also have writings on [[community standards]] and an [[anti-harassment policy]] which covers all conduct in the physical space and in our online spaces.

Leadership is taken by individual members for specific projects. We call this "sudo leadership" after the *nix command ''sudo'' which allows a regular user to do one root-level, or superuser, task. In other words, if you want Noisebridge to do something, start doing it.

Here's some paraphrasing from our bylaws:
Through talks, classes, workshops, collaborative projects, and other activities, we want to encourage research, knowledge exchange, learning, and mentoring in a safe, clean space. We provide educational spaces for teaching practical skills and theory of technology, science, and art. We provide work space, storage, and other resources for projects related to art, science, and technology that will benefit the individual members' personal growth in their fields of interest, encouraging the individual members to share their projects and knowledge for the betterment of society through art, science and technology. We create, learn, and teach, individually and as a group, inviting members of the community in the San Francisco Bay area and the world. We develop, support the development of, and provide resources for the development of free and open source software and hardware for the benefit of society. We promote collaboration across disciplines for the benefit of cultural, charitable, and scientific causes.

== Tripartite Pillars ==

===Excellence===
'''Be excellent to each other''' is the guiding principle of Noisebridge. Wikipedia uses [http://meta.wikimedia.org/wiki/Don't_be_a_dick a somewhat similar rule], which they call "''the fundamental rule of all social spaces. Every other policy for getting along is a special case of it.''" Unlike Wikipedia, Noisebridge takes a positive approach, and avoids the practice of officially enumerating the myriad potential special cases; ''' "be excellent" ''' is enough.

===Consensus===
We make official Noisebridge decisions by consensus, which means the willing consent of all of our members. Decisions are typically made at our [[:Category:Meeting_Notes|weekly meetings]] or via our online management venues, and items proposed for consensus are announced at least a week in advance to give everyone time to hear about them. Conceivably, members could block by proxy if they are unable to attend or if they wish to block anonymously.

More information on the [[Consensus Process]].

===Do-ocracy===
Doing excellent stuff at Noisebridge does not require permission or an official consensus decision. If you're uncertain about the excellence of something you want to do, you should ask someone else what they think.

== Testimonials ==

[[Testimonials | Why people love Noisebridge]]

* Smart creative people, welcoming community, friendly to newbies
* Equipment, tools, books, materials, and the space itself
* Its culture of free, open, accessible, DIY awesomeness

== Financing it ==

We self-finance through membership fees ($80 per member/month with $40 "starving hacker" rate), beverage sales, and parties, the way European hacker spaces do it. We also welcome one-time or recurring [[Donate_or_Pay_Dues|donations]] from members and non-members alike. Donations and sponsorships will accompany renovation and equipment purchase. Within the first 24 hours of renting a space, we raised over $10,000 for a cool location and meaningful projects. Within our first month, we've nearly become cash flow positive from membership dues alone. Further discussion is happening on the [[Finances]] wiki page.

== Inspiration ==
Noisebridge is inspired by similar European clubs like [http://en.wikipedia.org/wiki/Metalab Metalab] of Vienna, [http://en.wikipedia.org/wiki/C-base CBase] of Berlin, [http://www.mi2.hr/ MAMA] of Zagreb, and [http://en.wikipedia.org/wiki/ASCII_%28squat%29 ASCII] of Amsterdam. Many other clubs of a similar stripe can be found at [http://hacklabs.org/index_en.php Hacklabs] and [http://hackerspaces.org/wiki/List_of_Hacker_Spaces Hackerspaces dot Org]. It would not be out of the question to consider Noisebridge a possible [http://events.ccc.de/2007/09/27/say-hello-to-bitkanonecccde/ San Francisco Chaostreff]. Noisebridge is a hacker space and community that shares a [http://en.wikipedia.org/wiki/Dorkbot Dorkbot]-like ethic, and indeed, many of the members of Noisebridge are long-time Dorkbotters.

== The Name ==
A "noise bridge" performs useful services by injecting noise into a system. Such a device is often used in RF electronics.

Do-ocracy

2018-01-04T23:57:24Z

Mcscope: Reverted edits by 199.249.223.46 (talk) to last revision by Augur

Typically when someone wants to do or change something big at Noisebridge, they bring it up at a meeting and it goes through our [[Consensus Process]]. Most of the time many of us just don't want to be troubled with spending a week figuring out if everyone is ok with a small or mundane thing, and so there's Do-ocracy. Do-ocracy tends to work just as long as our only rule is followed, to be excellent to each other.

'''Do-ocracy: If you want something done, do it, but remember to be excellent to each other when doing so.'''

An important part of being excellent is documenting your change. Write a note on Noisebridge's [[ChangeLog]], or leave a note on what you do-ocratically did. Contact numbers are especially important if you want people to contact you about the change. The biggest challenge in a do-acracy is not reversal, but ascertaining (and taking) responsibility.

==Use Cases==
====The Short Version====
# Dick asks around if anyone would feel negative about the bike shed being pink. No one does.
# Dick paints the bike shed pink.

====The Being Excellent To Each Other Version====
# Dick paints the bike shed pink.
# Jane becomes unhappy about the fact that the bike shed she helped build is now pink.
# Jane politely engages Dick in discussion about why he thought this was ok. Dick realized that other people he shares the space with have feelings too.
# Jane and Dick decide to repaint the bike shed blue.

==Notes==
* Do-ocracy works most of the time. When it doesn't, it sort of sucks.
* Write a note (with your name or nym) saying what you did.
* If someone nicely asks you to change something back, be nice back and just change it back.
* If someone's being a dick to you about something you've changed, be nice and just change it back. If you must cry about it only do so after you've restored things.
* When Do-Ocracy means Consent.

Anti-Harassment Policy

2018-01-04T23:57:20Z

Mcscope: Reverted edits by 199.249.223.46 (talk) to last revision by Augur

The canonical text of Noisebridge's anti-harassment policy is on [https://github.com/noisebridge/bureaucracy/blob/master/code-of-conduct/anti-harassment-policy.md Github]. It is reproduced here for convenience.

<blockquote>
Noisebridge is dedicated to providing a harassment-free experience for everyone, regardless of gender, gender identity and expression, sexual orientation, disability, physical appearance, body size, race, religion, housing status, or language. We do not tolerate harassment of people at our events or space in any form.
</blockquote>
<blockquote>
Harassment includes offensive verbal comments related to gender, gender identity and expression, sexual orientation, disability, physical appearance, body size, race, religion, sexual images in public spaces, deliberate intimidation, stalking, following, harassing photography or recording, sustained disruption of talks or other events, persistent uninvited communication, inappropriate physical contact, and unwelcome sexual attention.
</blockquote>
<blockquote>
Different users of Noisebridge have different levels of comfort about sex and porn. Nobody should be forced to experience sexual or sexualised language or imagery. This does not mean that such material is prohibited, just that such conversations, presentations, &c. should include only interested and consenting people.
</blockquote>
<blockquote>
When you are working on a sex- or porn-related project at Noisebridge, or are running such an event or presentation, provide reasonable notice and warning to allow others the opportunity to opt out if they wish. With this — as anything else — each person has a responsibility to be considerate of the comfort levels of others. Discussions, projects, and events of this nature should strive to exist in a culture of respect and consent.
</blockquote>
<blockquote>
People asked to stop any harassing behavior are expected to comply immediately.
</blockquote>
<blockquote>
People violating these rules may be sanctioned or expelled from the space or the event at the discretion of any Noisebridge member.
</blockquote>

If you wish to report harassment anonymously or privately, you can send a message to secretary@noisebridge.net (or contact one of the people who have volunteered as a mediator on the [[Mediation|Mediation]] page).

Welcome to Noisebridge! We're glad you're interested in our space and we look forward to seeing you soon. Here's some advice to help you
understand what you're getting into and see if it appeals to you.

====Who is welcome====
Everyone is welcome and encouraged to visit Noisebridge. We ask that visitors follow our [[Noisebridge_Vision#Tripartite_Pillars|guiding rule]] "to be excellent to each other" in the best spirit they can; please see our [[Getting_In|access policy]]. New visitors can drop by anytime unannounced and do not necessarily need an invitation for a tour or for attending a scheduled event/class. It may be wise to follow our suggested advice below on the best times to visit, to ensure there are people there who can let you in.

Noisebridge is [[Accessibility | wheelchair accessible]] though people who use wheelchairs may need help with the heavy manual [[elevator]] doors.

====Come with an open mind====
Noisebridge is largely about learning and exploring, and there's lots to see and learn here! Activities at Noisebridge include hanging out, working on personal or group projects, and scheduled or improptu workshops and classes on a range of topics, from foreign languages to photography, lockpicking, woodworking, computer programming and mathematics.

====Some times are better than others====
We have many scheduled activities in the space, and many of us have day jobs. You can coordinate the time of your visit to ensure that you can find people to talk with (and especially [[Getting_In|to let you into the building]] in the first place!)

* Are you new? Wondering when to drop by? Come by any evening - you don't necessarily have to wait for a class, an event or a meeting. Any night there will generally be people hanging out, and you're welcome to just show up, to say "I'm new!" and then get a tour, or to just relax and work on your laptop until a conversation of interest comes up.
* If you're interested in particular activities, check out our schedule, posted on the [[Noisebridge|main page]] of this site.
* If you'd like to come during unstructured time and talk with lots of people, after hours are generally best.
* If you'd prefer a quieter environment, come earlier in the day.
* If you'd like to see the anarco-syndicalist factory of how a long-living hackspace is maintaining, tag along to our [[Meeting|Tuesday 8pm meeting]], where affairs are often '''excitingly''' hashed out.
* You're unlikely to find many people in the space before noon on most days.
* This is discussed in painful detail at [[Hours]]
* The people around you may not know you well, but they might love you a bit more if you fix a random thing. Even if its just cleaning plates of dishes, helping to organize the parts bins, or tidying an obviously dirty desk.

====Who's in charge?====

YOU ARE! (with the consent of the folks around you!) Noisebridge attempts to be as leaderless and as non-hierarchical and unruly as we can get. We encourage anyone in the space to be as responsible as anyone else. If you're a new visitor, that means the member or vouchsafed guest who you first meet is as good as anyone else to ask questions of.

====Our code of conduct====
Our [[Noisebridge_Vision#Tripartite_Pillars|chief guiding principle]] is to "be excellent to one another". Please respect the other people you meet at Noisebridge and the Noisebridge space itself.
We welcome visitors because we believe in our community and want to share the things we're working on with everyone. We also have [[community standards]].

====Other people's stuff====
Please try to be careful with the things you find at Noisebridge, and recognize that the things on shelves are other people's stuff.

====Not "child-safe"====
We have not limited what we like to explore or discuss according to anyone's notions of "appropriateness" for children. Thus, anyone entering the space can be exposed to ideas, concepts, language and items which some would consider "adult-themed". We also have some tools and materials that can be hazardous for children or adults if used improperly. Children are as welcome in the space as any other person - just be prepared for what they may encounter.

====Hostile network====
The network at Noisebridge - like any public network - should be regarded as potentially hostile. This means that you should assume that any unencrypted communications over the network could be (and most likely are) monitored by others. Examples of vulnerable communications include POP3/IMAP email clients, most web browsing, IRC/AIM and similar chat protocols that are often not encrypted. While no issues have come up to date, and our code of conduct opposes malicious monitoring of others, it is wise to be aware of the potential. Stick to using SSL or secure tunnels or VPNs for anything that uses a password or that you otherwise wouldn't want other people to read. If you don't know how to protect your communications with encryption, many people at Noisebridge would be glad to help you out! (It would be nice if someone would provide links to a decent guide here.)

=====Attempt at a Semi Decent Guide=====

The most secure option you have is to set up [https://inside.mines.edu/~gmurray/HowTo/sshNotes.html an SSH tunnel] to a remote server, and then use a proxy server like [http://www.pps.jussieu.fr/~jch/software/polipo/ Polipo] to forward all your HTTP through that server. Done properly, this will encrypt all your traffic without any further worries. If you do not have SSH access to a remote server, then you can use Tor or similar to encrypt your traffic without exposing it to the Noisebridge network.

The fallback position is to ensure that as many services as possible use HTTPS by default (especially webmail) and at least have browser based solution to protect against [http://en.wikipedia.org/wiki/Cross-site_request_forgery CRSF]/[http://en.wikipedia.org/wiki/Cross-site_scripting XSS] attacks for everything else. This may happen even if the website itself is solid -- if you're on a compromised internal network, the attacker can inject content into any HTML page that you're reading.

Recommended Firefox Addons:

* Certificate Patrol: https://addons.mozilla.org/en-US/firefox/addon/certificate-patrol/
* Perspectives: https://www.networknotary.org/firefox.html
* HTTPS Everywhere: https://www.eff.org/https-everywhere
* Noscript (even with "all access" it still catches many CSRF/XSS attacks): https://addons.mozilla.org/en-US/firefox/addon/noscript/

Recommended Chrome Extensions:

* KB SSL Enforcer: https://chrome.google.com/extensions/detail/flcpelgcagfhfoegekianiofphddckof
* NotScripts: https://chrome.google.com/extensions/detail/odjhifogjcknibkahlpidmdajjpkkcfn

Recommended General Security:

* If you use Google, [http://googleblog.blogspot.com/2011/02/advanced-sign-in-security-for-your.html two factor authentication] is vastly more secure than just a password.
* Although coming up with a good password is nice, you're far more secure if you use a password manager like KeyPass or 1Password. The best password is one you don't remember.
* If someone gets their hands on the physical machine, all bets are off. Try to avoid strange USB sticks and CDs, even if they look shiny.

Hosting an Event

2018-01-04T23:57:09Z

Mcscope: Reverted edits by 199.249.223.46 (talk) to last revision by 93.115.95.201

==Overview==
We're happy to host teaching and co-operative events at Noisebridge. There's no charge, though please consult and respect the many others working in the space. Here are some suggested guidelines for hosting an event at Noisebridge, whether its a short workshop, a regular hackathon, or a bigger unconference-style event.

==Our Physical Space==
===Event-Hosting Areas===
Noisebridge has three primary areas within our physical space for hosting an event, consisting of two classrooms (Turing and Church) and a large open conference area (the Hackitorium).

===Accessibility===
Please visit our [[Accessibility]] page for a full description of how Noisebridge makes our physical space accessible to everybody.

Temporary access code for the gate can be set up for your participants.

==General Guidelines==
====Get members involved====
'''You don't have to be a member to start an event.''' It's recommended to involve at least one Noisebridge member as part of your planning to avoid common pitfalls when working with Noisebridge. Ask around the space for a member, or ask on the discuss [[mailinglist]].

====Communicate the event to the group====
'''Publicize the event to the users of Noisebridge''' via the 8PM Tuesday meeting, this [[Category:Events|wiki]], the [[mailinglist|Noisebridge discussion and announcement mailing lists]], and the [[IRC|Noisebridge IRC channel]], with enough lead time that the community can respond and give feedback. See also, [[Mailinglist/Announce_guidelines]] for help on writing a good announcement mail!

Be aware of the existing ongoing events and try to work around them, even if they're not in your part of the space. Some events like 5MOF and work in the shop can be noisy! Also events might be happening that aren't listed anywhere that may create annoying room scheduling issues.

====Setup and clean up====

'''Leave the space cleaner than you found it.''' Have a plan for setting up the space and have a plan for cleaning up after yourself (and follow it). Novice tip: At the end of the event or class, ask people who participated to help clean up the space used.
d

====Donations and fees====
'''Consider asking participants for a monetary donation to Noisebridge during your event.''' We have a recommended [[Preamble | one minute preamble]] for event organizers to say at the beginning of their meetings. It explains how we work, and how your visitors can help keep Noisebridge going.

Noisebridge prides itself in being an open space to all that are excellent. '''Please keep in mind that we generally don't host classes or events that have a participation or class fee.''' Charging for materials or kits is acceptable (such as buying a blinking LED kit to work on during [[Circuit Hacking Mondays]]), but shouldn't be required to join in the class or event.

====No age restrictions====
'''Noisebridge is an all ages space''', if your class or event has an age requirement, please bring it up at a Tuesday meeting or on our discussion mailing list before proceeding.

==Event Listing==
After taking all of the above into consideration, and feeling like Noisebridge is the right spot for your event, listing it on our events page would be great! Here are some steps to do so...

# Create an individual page for your event. Include contact info for the organizer(s), date/time, location (if at Noisebridge, where in the space), and a pretty good description of what the event is. The important bit is contact info, helps when we're cleaning up the events list.
# Include the code <tt><nowiki>[[Category:Events]]</nowiki></tt> at the bottom of the page.
# Go to the [[:Category:Events|Events]] page and add in your event to the correct spot. We use 24 hour time.
# The events listed on our [[Noisebridge|Main Page]] are actually pulled from the [[:Category:Events|Events]] page. So no need to add it again.
# If you have an event that happens once, or a reoccurring event that doesn't occur anymore, please remove it from the [[:Category:Events|Events]] page after you're done.

==Mitch's suggestion on how to do an event at Noisebridge==
We don't have a formal procedure for scheduling at Noisebridge.

But here's how I suggest doing it:
* First, take a look at the info on this page (above), where there's a bunch of good info.
* Look on the [[Noisebridge|Noisebridge]] website, and near the top, check out the '''Events and Classes''' section (both ''Upcoming Events'' and ''Recurring Events''), and find a time where Noisebridge can accommodate the crowd you're expecting.
* Send an email to the '''Noisebridge-Discussion''' list, and let folks know that you want to give your event. and when, and ask if there's interest, and ask if there is any conflict of space/time. (You'll need to subscribe: [[Mailinglist|Mailing List page]] -- but please know there are trolls there -- please do not feed the trolls.)
* If you get any positive feedback, then there that is indication enough that there people will show up (way more than give you feedback on the email list).
* Create a wiki page for your event on the Noisebridge website (which is entirely a wiki).
* Add the event to the ''Upcoming Events'' section, including the link to your event wiki page. Then post to the '''Noisebridge-Announce''' list (you'll need to subscribe -- [[Mailinglist|Maling List page]] -- and someone will approve your post -- this is the ''only'' thing at Noisebridge which is moderated).
* Publicize the hell out of the event to let people know it's happening!
* One week before, post to both the Discussion and Announce lists. And then you can post to both lists again the day before to remind people (and to catch last-minute stragglers).

==Procedural Checklist for Larger / More Impactful Events==

Some events are bigger than others.

If you are expecting more than (say) 20 people at your event, you may find the [[ProceduralEventChecklist|Procedural Event Checklist]] useful for thinking through mundane but important aspects of planning such as managing the cultural impact of the event on [[Noisebridge|Noisebridge]] at large and making sure there's enough toilet paper in the bathrooms.

Check out the [[ProceduralEventChecklist|Procedural Event Checklist page]]. (And don't get too overwhelmed; while quite long, it's meant to *help* you plan aspects of your butt that you may not have thought of.)

I have included a PDF for quick plotting, scaled for 36x24 paper and the original CAD file for future updates. I have been careful in my measuring but the walls of the space are not straight. Always verify measurements on site if tolerances for new projects are going to be tight.

'''A note regarding cutting metal in stationary tools:'''

The shavings that come off the metal piece being cut are HOT!

In a stationary tool that has been used on wood, there is typically a nice big thick bed of sawdust inside the tool. When the metal shavings fall into this bed of sawdust, an awesome smoldery fire can build up sight unseen inside of the tool. Yay!

When possible it is best to have two separate dedicated tools... and/or if one is going to be transfered over into metal service the inside should be vacuumed out first, and/or the operator should check inside the machine when they are done.

An open conference area occupies the central area of our building layout. The conference area contains three long tables and
chairs necessary to accomodate approximately 24 people. The tables may be moved to accomodate more chairs and more people.

The conference area has a ceiling-mounted video projector on one side and a remote-controlled drop-down projector screen on the opposite side.
We also have two large speakers located on either side of the projector screen. There is an audio receiver, mediacenter computer, and multiple
audio/video inputs along the side of the conference area for connecting a laptop or other a/v equipment to our projector and audio receiver.
Video inputs include HDMI, VGA, and DVI.

[[Image:NewLibrary.jpg|thumb|right|Our excellent library]]

= How do I add a new book to the library?=

# Find the book on [http://openlibrary.org Open Library]
# If the book is not there, create an account and add the book (2 minutes)
# Add the book's '''OLID number''' to our catalog: http://library.noisebridge.net/new/
# You will see a green bar when successful
## '''The Secret Code''' is on a sign in the library.
##Press the SUBMIT button!!

= Searchable Catalog / library-org=

We have a website to help find books: http://library.noisebridge.net

Capabilities:
# search - substring search by title, author, or subject
# new - add a new book
# explore - see all books in a random order
# all - see all books at once
# (toggle) - to see subjects on the right side

= Library: What's the point? =

'''There's already a public library!'''

Since there's a public library, we're going to focus on books that fill the needs of people using the space right now.

'''Anyone can access what they want over the internet almost all the time!'''

If electronic books are already accessible, we can focus on the people who would still prefer to use a paper copy.

'''A more refined goal:'''

The mission of the library is to serve technical or hacker-y literature to people in Noisebridge right now.

''' How do we get there? Quantify, Expand, Prune! '''

*First: Know what books we have. (done)
*Second: Create a process to acquire books that fill the library's mission. (we need a lot)
*Third: Prune our shelves a bit. Bring the average usefulness up. (needs work)

= What can I do? =

Lots of help is needed! There are 3 major things to do:

* '''Initiative 1''': Improve the collection: Collect sets of topic books from experts and source these books
* '''Initiative 2''': Add "topic"-based color on spine labelling system to library
* '''Initiative 3''': Improve [http://library.noisebridge.net] [https://github.com/robbintt/library-org]

== Things To Do ==

''' Initiative 1: Source New Books '''
* Are you really good at something or reasonably well read? Make us a list of must-have books!
* Add themed lists here: [[https://noisebridge.net/wiki/Resources/Library#Books_We_Want]]
* You can help acquire books by sourcing books on these lists!
* Don't subtract them from the lists, we can make a system for checking them off
* Who will give us great books? Anyone. Mailing list?

''' Initiative 2: Label by topic! '''
* Label all books already in library-org with subject "color" on the spine.
* Add: moveable magnetic labels you can slide paper into

''' Initiative 3: Improve library-org '''
* library-org is a Flask app
* Current capabilities: receive new books, substring search, add location to each book, register new locations.

= Bookshelf Directory =

You can find where various categories of books are found by checking out the visual directories posted on the two main shelves.

The files for these directories with editable form fields:

[[Media:Bookshelf-left.pdf]]

[[Media:Bookshelf-right.pdf]]

= Hacking the bookshelves =

The bookshelves have LEDs that operate on the flaschen-taschen protocol. Learn more [https://noisebridge.net/wiki/Bookshelves here].

== How many books do we have right now? ==

A book barcode scannning effort was performed in October-December 2015 using [https://github.com/robbintt/noisebridge_bookscanner noisebridge-bookscanner].

1657 books have been ingested into library-org using [https://openlibrary.org/ Open Library]

IMPORTANT: If you do any of the work below, be sure to update the list to remove the ones you added.

'''Here is a list of the barcodes that aren't yet in library-org.''' Each one represents an unknown book... please solve me.

</nowiki>

One way to solve these is to google the UPC individually and find the book it corresponds to. At least one of the books in here is available this way. Try to find out which one!!

'''Here is a list of ISBNs that aren't in openlibrary or library-org.''' The workflow to add these is to find them on amazon, type the data into OpenLibrary, then import the OLID into library-org.

=Finding Books=

If you want to find good books for our shelves, go to the '''San Francisco Public Library Steps Sale''' every Wednesday 11 AM to 3 PM at the SFPL main branch (civic center). Books are on sale for $1 each.

=Books We Want!=

People with experience and opinions about various topics can add recommendations below for books we should buy for the library.

There should probably be a fourth column indicating if we have the book or not.

Sewing

= Latest News =

[[File:Sewing.jpg|300px|right]]

*For the latest announcements, please subscribe to the email list here: https://www.noisebridge.net/mailman/listinfo/sewing/

= Overview =

We have five mostly functional sewing machines:

Industrial style machines:
* Single Needle Lock Stitch (Juki DDL 227)
*Straight Stitch Walking Foot (Juki LU-563)
*Five-thread Overlock Serger (Juki MO-2416)

Home-style machines:
*Brother SE400 Combination Computerized Sewing and 4x4 Embroidery Machine
*130-Stitch Computerized Sewing and Quilting (Brother XR1355)

We also have these sewing amenities:
* Giant ass table with cutting mat surface (50 inches x ? inches )

* Irons and Ironing board

* Big donation bins of extra thread and fabric you can use for projects

* lots of odds and ends

* 2 dress forms

- Full length mirror

= Tips =
* Please DO NOT unthread the sewing machines unless you must. (e.g. to remove a spool of thread, simply cut it close to the spool so that the next person can simply tie a knot with the next thread and pull it all the way through to the needle). This is most important for the serger.

* Needles, bobbins, and other parts are located in labeled drawers underneath the pegboard (PLEASE KEEP IT ORGANIZED). Also check the drawers attached to each sewing machine table.
** The closest place to get parts is at Apparel City, on Howard between 11th & 12th.
** Needles may differ between machines and come in sizes (10, 12, 14, 16, etc.). The higher numbers are heavier gauge needles suitable for thicker fabrics. Leather needles have a tiny blade at the tip. Don't use a leather needle for other fabrics, though, it will cut the threads rather than squeezing between them, leaving holes that may start rips.
**Needles for the straight stitch machines must be inserted with the scarf facing right. Please check the respective manuals.

* If you've never operated a sewing machine before, ask some people at Noisebridge (Kyle or Ely). Sewing machines are not self-explanatory and this page does assume a certain amount of prior general knowledge.
**Read the manual and do some research online.
**Printed manuals for the two Juki Machines and the Thompson are located in a grey binder on the bookshelf

*Use scraps for testing to determine thread tension and sewing speed.

==Winding a Bobbin==
*Juki DDL-227 & Juki LU-563
**To wind a bobbin, place the empty bobbin on the horizontal spindle to the right of the machine body (near the hand wheel). Run a second thread through the upper holder, down to the tensioner at the back of the right side of the machine, in line with the spindle. Thread the end through one of the holes in the bobbin side, from the inside to the outside. Press the lever to push the spindle down in contact with the sewing machine belt. While holding the thread end so it doesn't just whip out of the bobbin, press the pedal to run a couple of inches (if there were fabric in the machine). Soon enough you can let go of the thread end as it will have been caught by windings on top of it. If you are doing a lot of sewing, you can start a new bobbin before the current one is empty, and let it wind up as you sew. When the bobbin is full, the lever will automatically snap out away from the belt and stop winding thread.

== Repairing a Sewing Machine ==
* If a sewing machine is actually broken and non functional, as opposed to just you can't figure out how to make it work, please call Billy from Apparel City at 415-816-8645 (mobile) and schedule an appointment for him to come fix it.
** He usually charges around $80 per hour, plus parts.
** Email the [https://www.noisebridge.net/mailman/listinfo/sewing/|sewing list] and people will chip in to cover this. If you can't manage this process, email the sewing list and find someone else who can. Also, please put a note on the machine so people know what is going on with it.

== High Speed Lock stitch (Juki DDL 227) ==

*[[Juki Maintenance Notes]] - Replacing the counter knife, needle bar, thread guides, etc.
These were originally written for our old DDL-5550-6 machine but the 227 is very similar.

=== Overview ===
* General fabrics, light-weight materials and medium weight materials.
** '''Not for leather or book binding.''' Please use the right tool for the job.
* Clutch motor (fast!)
*Recommended thread size of Tex-40 in the DDL

=== Manual for Juki DDL-227 ===
PDF - https://www.manualslib.com/manual/1005359/Juki-Ddl-227.html

== Straight Stitch Walking Foot (Juki LU-563) ==

*This is a high tension machine. You must press the knee lifter to pull thread through. This will release the tension.
**Conversely, DO NOT run into the knee lifter at all while sewing. This will release the tension and your stitches will be too loose.
*Pressing back or letting go of the pedal will engage the brake. Slightly depress the pedal to release the brake. You must do this to use the hand wheel

=== Overview ===
* Medium weight and heavy weight materials, leather and vinyl
** Not for light-weight materials!
* Clutch Motor
** This machine is VERY fast
*Horizontal Bobbin
*Recommended thread size Tex-70 in the walking foot

=== Manual for Juki LU-563 ===
PDF - http://keysew.com/Webpages/DemoImages/Juki_LU-563_Instruction_Keyfooter.pdf

== Five-thread Overlock Serger (Juki MO-2416) ==

*Pulling fabric out of the machine may cause thread breaks. It is best to feed thread with the pedal when removing your workpiece.
*DO NOT UNTHREAD THE SERGER. It takes about 30 minutes and a lot of patience to thread this machine. However, if you are an experience user of industrial sergers you will be able to thread this machine quickly. Using tweezers helps. Also, using the correct thread for the correct machine is essential. Good Luck and happy sewing.

=== Overview ===
This machine is not made for knits. It is made for wovens. It is a five spool. It has a clutch motor and this is the reason that it goes so very rapidly. The overlock sews to prevent fray. However, the machine make a chain stitch at the same time. For example, if you were to look inside of your jeans, you can observe these methods. A chain stitch and overlock. This type of machines is used for medium weight fabric.

*This machine has a knife placed to cut the fabric as you sew, and it *is possible* to cut your finger badly on this knife if you are not careful. BE CAREFUL. This machine also can go extremely, sometimes startlingly, fast.

=== Manual for Juki MO-2416 ===

* PDF - [[Media:JukiMO240424142416.pdf]]

== Brother SE400 Embroidery Machine ==
This machine is awesome, and can do many different stitches as well as CNC embroidery.
It's usually stored on the wall of the sewing area. It looks like a home sewing machine but is as expensive as an industrial one and is many people's favorite machine.
[[Embroidery Machine]]

== 130-Stitch Computerized Sewing and Quilting (Brother XR1355) ==

*This machine is stored away in one of the sewing area cubbies.

=== Overview ===
*This machine does 130 different stitches including lots of cool decorative flowers and patterns. It is also the only machine that can do a zig-zag stitch.

=== Manual for Brother XR1355 ===

* PDF - http://download.brother.com/welcome/doch001142/xr1355ug02en.pdf
