Laser Cutter (G Weike) (view source)
Revision as of 23:15, 27 November 2023
, 23:15, 27 November 2023corrected issue where all info was under "standard operating procedure"; added information about the version of lightburn on the laser computer and about lightburn licenses; removed out-of-date information re: starting the laser cutter; added information on the filter box and manometer; deleted out-of-date pictures of old display panel and old lasercut software; removed references to pressing the DATUM button (not present in new software)

==Training Documentation==
The most up-to-date laser training documentation is on [https://docs.google.com/document/d/1WrFRr2PYigtJgjik5aB2APOgW7888TnDHTC34omh4KM Google Drive].
==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].

===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.
*There is a white box in-line with the ducting to the exhaust blower. This was from an attempt to filter the exhaust before sending it out into the wide world, but the number of filters we were going through was unsustainable.
*There is a simple pressure indicator (a [https://en.wikipedia.org/wiki/Pressure_measurement#Liquid_column_(manometer) liquid column manometer]) installed on the filter box. When the blower is off, the liquid in the two sides of the tube should be level. When the blower is running, there should a difference of a couple inches.

*Fire: Be sure to always be in clear view of the laser cutter as fire is a very real and dangerous reality. If there is a significant fire, press the emergency stop button and put out the fire with one of the 2 CO2 fire extinguishers available. For a small fire, you can try to blow out the flame.
*Fire: Be sure to always be in clear view of the laser cutter as fire is a very real and dangerous reality. If there is a significant fire, press the small “STOP,” then “DATUM” button on the software and put out the fire with one of the 2 CO2 fire extinguishers available. Be sure to familiarize yourself with where the “STOP” button and the “DATUM” button is on the machine and software, respectively. For a small fire, you can try to blow out the flame.
*Do not use any material that might have chlorine. You can check by heating a copper wire in a flame, touching the material, and then reheating the copper wire. If the flame emits a green colour then there is chlorine in the material. See [https://en.wikipedia.org/wiki/Beilstein_test Beilstein Test] and a [https://vimeo.com/1615418 video demonstration].
