Is there any reason my laser will suddenly lose power in the middle of a job, or is my tube dying? I engrave rolling pins, and in the space of 1cm the engraving went from 2mm deep to barely marking the surface. I thought when tubes die they gradually lose power……
Hi, do you mean the laser has permanently lost burning power? To check this, please place a small piece of paper in front of the reflective surface of the mirror on the left hand side of the gantry, and run a job. As soon as you see smoke from the paper, turn off the power – you’ve proven there is laser output. If you got output, then the next step is to align the mirrors. If no output, check these tips https://awesome.tech/mg3-mini-gerbil-debugging-laser-operation/ and liase with our tech support via firstname.lastname@example.org
