This is a new one for me. I suspect it’s some kind of hardware issue though I’m not sure how to diagnose. It seems no matter what program I load on my 4’ x 8’ flatbed laser after about 20-25 minutes of continuous cutting all of a sudden my cut patterns will just grossly distort for what seems to be no reason. The display shows the correct cuts when the file is loaded but as it progresses it starts to display these distorted shapes. The controller is outputting these erroneous shapes to the display looking just as they cut. Never seems to happen in the same place. Sometimes it will shift a shape to the point where it will hard limit from trying to cut out of bounds of the cut area. See attached photos. I’ve tried slowing down acceleration settings and speed in general but at some point this appears to just repeat. Has anyone experienced anything like this before? Controller issue? Maybe a stepper driver going bad? Any thoughts on how to diagnose are appreciated.
