Calibration off but not a percentage

What I mean is my x is off by .015. Same on a .5 carve or a 3” carve all consistently off by 15 thou

Y is off by .010 same deal consistent from small to large all off by the same amount.

Since it’s consistent I feel like it’s not $100 or $101.

What do yall think?

That sounds like a backlash issue or bit deflection.
