Is that engraving? It looks like cutting.

sorry for the miscommunication,
everything i did and uploaded is vector cutting (just not through).

Ok - so set the backlash back to 0 because it is really only for engraving. Try set the Auto close curves to 0.1 - or even as high as 0.5. If none of that works, you have a gantry straightness issue.

Thanks for the tips!

unfortunately it didn't work, i was able narrow down my issue to backlash in the X (and probably Y) axis.

i checked part of the gantry yesterday against a reference piece, and over 200mm i got <0.02mm deviation. so it might still be off for large pieces but probably good enough for smaller 45mm circles.
