I have a 60W red and black laser and I can’t seem to fix these wavy lines.
They look a little line sine waves, and they happen mostly on long straight lines. I feel like it’s some type of mechanical vibration or chatter. My mirrors are locked down tight. I just took out the lens to clean it and make sure it’s seated properly, and I just tightened all of the belts but I’m still getting the wavy lines. The belts now make a now “pong” sound like a bass guitar string. Is that too tight?
I wonder if it’s just the way the lens is mounted that’s letting it wiggle? It’s the lens/nozzle that came with the laser and doesn’t seem like great build quality.
I’m engraving at 300mm/s. Is that too fast? I can go up to 350mm/s and it doesn’t seem to be any worse at that speed.
Is it possible to upgrade the motor drivers? This is commonly done on 3D printers to make them smoother and quieter.
