Yep exactly that.

If I have read this right then the pattern is very regular, in fact it looks cyclic.
One clue would be to measure the ridges and see if the measuremet tied in with say ball screw pitch.

Another thought is that on that profile it will be working Y and Z can you try a sample using X and Z ?
Its working on both. Also in that pic you can see the same pattern on the other face although this is more tightly spaced. Could this have something to do with ball screw pitch as there's more Z movement there and that's 5mm pitch whereas its 10mm on the others?

ast thought is to post a section of code that covers one of these passes.
Don't post the whole code we only have until 2020.
Here's a section from the very start of the 3D operation.
