Round pockets not round (solved loose grub screw)

Machines (Original/PRO)

When creating pockets I am finding that they are off center and really out of round. I’ve searched around and ensured that my motor 0 is indeed set to 16mm travel per rev, and my toolpaths in vectric are round. The through holes are fine and the curves are milling out correctly, it’s just the pockets that are out of whack.

Any ideas?

There are threads that show similar results when someone accidentally removes the red bushings from the stepper motors or the stepper motor couplings are not tight enough.
