Laser Cutter Venting System

NOTICE:
Laser cutters are expensive and dangerous.
All of our laser cutters are ducted and require venting.
YOU MUST turn the ventilation system on before you use any of the cutters.
Do not leave them unattended. It is a fire hazard.
Some jobs take a long time to run. If you need to run to the bathroom or something, find someone to watch it for you.
