It look mechanical but to check cut the part with and without the THC to answer that quickly.
Not knowing the orientation of the part to X and Y axis travel but it could be when both axis are moving at the same time with some slop in the movement. Did you check the number of nodes in the area of the problem.

It's not the nodes as I have cut it many times. The old software doesn't work so I can't test it. I will try without height control. It could be mechanical as this new setup had caused it to crash a few times already.
Guess I will keep rocking it and see if a bearing breaks
OOO i think I found it. There is just a very tiny amount of slop in the z axis. I am going to cut out a new plate to replace the back of the z lifter plate and bolt to the existing mount. Should have it done soon, the only issue is I have to take it all apart to see if it fits lol
