Hello All, I am a newbie to the laser community. I have a new Ortur LM3 with a 20W laser. When I connect with Lightburn and start a program, the air turns on, the X-Y moves to follow the pattern, but no laser. I have yet to get the laser to turn on, not even the low power outlining. Am I missing a setting in Lightburn or is there something wrong with my laser?
