I’ve been working on getting full-wrap tumblers up and running, all is well except there are lines ever so often in my designs? I know speed and power play a part, I’ve messed around with those settings but turning it up too high also causes grid lines in the engravings even though it gets rid of the lines (mostly, still not 100% gone)
The spacing between the lines looks consistent, would it happen to be precisely your split size in rotary settings? What’s your overlap set as? I’d bump the overlap up slightly, or vary your split size to see if the lines shift the same amount
edit: I’m accustomed to galvo stuff, didn’t realise GRBL/DSP doesn’t have that option, but makes sense.
