==Lightburn License==
Lightburn's business model allows users to pay once and get updates for a year, then continue using that software (without further updates) for as long as they wish. For this reason, the copy of Lightburn on the laser cutter computer is frozen at 1.0.06. Lightburn has provided us with a discount code for our members to purchase a limited version of the software, please contact the the laser team/trainers to get the code. More information on Lightburn licenses [https://lightburnsoftware.com/pages/how-the-lightburn-license-works here].
=G Weike Laser Cutter - Standard Operating Procedure=
==Laser Etiquette==
==Laser Etiquette==
Use of the laser is first-come, first-serve. If you are going to be on the laser for a long time (2 hours or more), please notify other members via Slack in #tool-laser. Kwartzlab members have been great at being flexible with use of the laser, often letting others jump in between cuts/engraves if someone has a small job to perform.

===Clean Up and Turning Off the Laser===
===Clean Up and Turning Off the Laser===
#To turn off the laser cutter, exit the software and press the “stop” button to turn off the machine. A red button will flash while the bulb cools. Note: do not hold down the stop button when you turn off the machine.

=Materials=
'''Flat materials''' are ideal and strongly recommended. Warped materials can be flattened with magnets, but use them with extreme caution. Magnets in the path of the laser can damage the nozzle. Material that is cut can warp up into the path of the laser nozzle also causing damage. Flat material is best!

*Burn marks: Burns marks might appear behind the cut. To protect the surface of your material, you can tape (use painter’s tape) on the back of the material. If you are cutting a plastic board, then keep the film that it came in on the plastic board to protect the back from creating white floss.

==Material Power Speed Guidelines==
'''NOTE''' These are starting points. Adjustments will be necessary based on variations in material, alignment of mirrors, age of the laser tube, and other factors.

*Vent/filter/honeycomb bed: Do not expect that the vent/filter on the bed of the laser cutter is squared to anything. This vent/filter is moveable and requires regular cleaning. If there are lots of little bits in the vent/filter, then clean it up by using the brushes in the computer station. If necessary, use the assigned vacuum and lift the vent/filter to vacuum the dust.

*The blower/fan above the ceiling has a mesh filter that becomes clogged over time. If you notice a smoke buildup in the laser during operation, it is likely due to this filter clogging. Please notify the laser team if this is occurring. If you feel comfortable, the process for cleaning the filter with a vacuum is posted on the wall next to the duct leading to the blower.
*The blower/fan above the laser has an intake grate that becomes clogged over time. If you notice a smoke buildup in the laser during operation, it is likely due to this grate clogging. Please notify the laser team if this is occurring. If you feel comfortable, the process for cleaning the grate with a vacuum is posted on the wall next to the duct leading to the blower.
