I have a 60w IPG_YLPM mopa fiber laser. I want to engrave a depth map on a coin but the image isn’t coming out. The preview is mostly black in Lightburn and the coin basically engraves that way on the coin. I’m sure the issue is with my settings. I tweaked speed, frequency and Q-pulse. Nothing much changes. I don’t want to keep ruining coins. Should I see a good representation of the depth map output in the Lightburn preview? What should I tweak in the settings?
My cleanup pass: bidirectional fill, 3000 speed, 100 frequency, 20% max power, 200 Q-pulse, 0.010 line interval, 0 scan degree, every 5th pass, 0 angle increment.
