[Noisebridge-discuss] Moar Laser Cutter Infos

Wow, that's some super useful info Danukeru!  Good thing we discussed this on this list so you came across the thread.  

Mitch, if you are going to China why not just ask about the parts we need from the company based there?  Their website is actually printed on the PCBs inside the Laser Cutter: http://www.jnmydy.com/

If you get the PCBs direct from them I bet it will be much, much cheaper.  I sent them an email in English (on their English website version) but received no reply yet.  Perhaps someone can translate?

and again, let me try and fix the main power PCB before we make any decisions on buying a new one (unless someone has money to burn!).  It would be a super huge waste and would be like replacing an entire car when you just need a new battery and wheels.

 If we can fix the old
 one, that'd be sweet.  Why waste our hardware?
 
 
 But, if that
 isn't feasible, or if we also want a new one:
 
 
 Our laser
 cutter cost us ~$2,000, including shipping (in ~2009).  For
 about the same amount of money, we could probably get a
 better one.
 
 
 I'm now at CTRL-H Hackerspace, in Portland,
 and they have a 40W laser cutter that looks very similar to
 ours, which they bought awhile back for about the same
 amount (~$2k including shipping).
 
 
 I'll be in China again at
 the end of the month, and could order one from TaoBao, if
 someone does some research on Aliexpress on which one to
 buy.  (Though, on Aliexpress, shipping is often free, so it
 may actually be a better deal to buy a new one from
 Aliexpress and ship it to Noisebridge from the supplier,
 rather than me shipping from China).
 
 
 Best,
 
 Mitch.
