I think I narrowed down these lines to a rotary module issue. like there’s a slip or something at each step. Has anyone else had these issues? Using 2w 1064nm laser on SS coated cups. Each image is either from Luban or Lightburn and both setup parallel along the Yaxis in the snapmaker 2.0 and the Ray.
Because you use the 2w IR laser, you use the latest firmware, right?
Yes I would assume both my machine have the latest firmware. Both were updated when I set them up recently.
I may imagine that - but looking on your first photo, I seem to notice the lines continuing in a second laser job above:
That would be a lot of conincidence - and might hint on some production residue from the making of the cups. You have the original in your hands - would you agree with my observation, or am I hallucinating?
