I just recently got a 80 watt Co2 lasermachine with Ruida controller. I wasn’t really happy with the results I got with engraving, I figured out that the laser beam (or dot) weren’t correctly focused. So I put the laser beam in the middle of every mirror, except the laser head mirror. But since that moment, it went wrong totally. It keeps ‘burning’ even while travelling. In the beginning it won’t and a few seconds in the process, it does.
Been trying to figure this out for a week now by looking on online platforms, still haven’t find anything. Someone on here know what the problem might be? I’m all new with lasermachines.
