 TheLab has a few different laser machines which can cut and engrave wood, acrylic, foam, steel, aluminum, etc. Each machine is better suited for different tasks. See the machine list below.

-## Safety Considerations
-The laser machines are a little different from most machines found in TheLab. There are no obvious sharp spinning blades that catch ones eye as being dangerous. The danger from the lasers is not so much the motors running as it is the silent high intensity, mostly invisible laser light. If it can cut/engrave solid material it will do major harm to human flesh.
-Be sure to read this safety discussion before burning your first project.

+## Software
-----
+Lightburn is used to drive all lasers at TheLab, with the exception of the Glowforge which uses proprietary software.
-## The driving software
-The various laser machines may use different software to actually drive the machine mechanism. Some may use a locally installable 3rd party product, others a proprietary cloud driven product. To date we have:
-### Lightburn
-Lightburn is used to drive the Trogdor (CO2) and Shockwave (OmTech Galvo diode) lasers

-There is a Glowforge proprietary cloud product that drives the Glowforge laser

+#### CO2 laser safety glasses
 For the Trogdor, Glowforge and Xtool D1 machines, the laser light should be contained by their respective enclosures. The laser “should not” fire if the access doors are open. It is imperative that one does not defeat/bypass the door interlocks such that the laser will fire with the door open. This is dangerous for the operator as well as anyone else who may traverse the immediate area.

 There is a fire extinguisher located next to the large red Trogdor machine.
+* If a fire has started immediately turn off the laser main power switch. This should allow the fire to extinguish, if not you will need to resort to using the fire extinguisher. It’s a CO2 extinguisher so should not damage the machine.
+* Immediately notify TheLab discord channels and put a note on the machine to not use until it gets checked over for damage.
