Purpose
This is a safety training required for using the laser at Noisebridge. The training does not cover the complete workflow of creating and importing a design.
This is the only required laser training.
Training Outline
- The Laser Is Dangerous
- Laser beam can start a fire
- The laser head (black thing that moves around) doesn't have sensors to prevent hitting things (your hands / side of the bed)
- Laser beam cannot be looked at directly unless through the protective cover
- Laser can emit poisonous fumes if the wrong materials are cut
- How To Be Safe
- ALWAYS WATCH THE LASER BEAM CUTTING YOUR WORK!
- USE REASONABLE SPEED/POWER SETTINGS
- DON'T CUT UNAPPROVED MATERIALS!
- How to Put Out a Fire
- Push the estop
- to turn the machine back on after the estop was hit, flip the power switch on the right side of the machine off and then back on
- Open the lid
- 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
- Push the estop
- Demonstrate Workflow - Perform a cut (from a logged out user screen with no programs open)
- Unlock the screen
- Load the laser training .rld file (the power and speed settings should be wrong)
- Open the page on the wiki
- Check power and speed settings are correct for your material (the file should have incorrect power and speed settings to force this step)
- Name the file BAD or something so people normally using it don't use the wrong settings
- Turn on the laser and check the chiller (CRITICAL STEP)
- The chiller is water cooling
- The chiller must be turned on whenever the machine is on. It must be below
- Download the file to the machine
- Place and focus the material
- Carefully open and close the lid (it's not a gym machine yo)
- Use the laser cutter control panel to run the file
- Frame the item
- Janky power button
- Check the power button with a very brief tap of pulse button if it won't damage your material
- Remove the material
- Power down the laser (room switch only)
- Clean out the catch tray beneath the cut bed
- The laser is run on donations
- Calculated to cost $5 per hour of cutting time based on repairs
- Please put cash in the metal bin on the wall
