Chinese 80w Trocen AWC laser has always given me rough cuts or lines. I've tightened pulleys, cog screws and belts but still get the bumps in exactly the same place when doing a circle.
If I reverse the line path they are still in same place. I've redrawn the circle in Lightburn and ran again.
I'm using Lightburn but also sent file with RDWorks and have same issue so it must be mechanical
Any help would be greatly appreciated..
