Looks like a loose belt… However, hoping @OrturTech may know quickly.
Hmm I’ll check, but I wouldn’t say it’s a belt.
DPI 300
down up
about 2.5h
No, horizontally… but I think it’s up to the belt because it was a little loose than the x axis
i will try to make one picture so i will let you know how it turned out
What happens if you just engrave vertical thin rectangles of different heights. Is it OK to a certain length. Is the track free running. If you put your hand lightly on the head while it’s moving do you feel a step or see anything…?
