Okay, I’m on my 3rd Chinese laser, a 100w red & black with a Ruida controller that got delivered to weeks ago. The laser scans fine, no issues there - pictures come out great
My problem is cutting. I can make perfect circles and squares until I raise the power to cut to say, 50%. when the speed is 20 or below - ghost rings. the table is level, mirrors appear to be aligned correctly ( I changed the original lens because of a spot no difference) The head is level. No clue. Only happens on higher power and at lower speeds.
