Hello All -

Looking for some help dialing in some very fine Z movement.

I am experiencing these depth changes and looking for help in removing them. Running this on a PRS Gantry Alpha 96-48-8 with an ATC. I've taken the plunge and feed rates way down and have experienced some improvement but still get the below results.

STAR BAR
This circle of stars sit on a concave base. One side of the circle is slightly raised, the other side of the is slightly lowered below the surface.

LETTERS
Looks like Z height is a struggle on these letters.
