Good day. I am having an issue with burning on my 50w chinese laser using Lightburn. When I go to burn at max 65% power, and minimum 50% power, for a roughly true 40w rated tube, I get a double line. I get the main cut line and a phantom mark line along side some of the work, as if there was 2 beams being fired at once. Keep in mind this is only 1 pass, and the phantom line only shows intermittently. The second phantom line is more of a superficial cut that can be removed with some sand paper after a little sanding. Any help with figuring this out would be greatly appreciated. Thank you.
