In Easel, I’m making a rough cut with a 1 mm bit and then changing to a .3 mm bit to carve the details. It looks like it’s only shifting in the positive y direction.
I’ve been able to get the rough and idle passes synced on another piece for this project, but for THIS piece, I keep getting this result. I’ve done the idle motor lock thing, and I’m certain that the gantry is not shifting.
Also, I’m not doing this as an actual rough/detail pass in Easel. I set the detail path to a depth of 0 and cut the rough pass, then reverse this after I change the bit. I don’t see how this would make a difference, but it might.
