Steps per unit calibration

Seriously, grab the spindle and wiggle it. Anything that moves is a target for manual tuning.

Also, your cutters may not be perfectly sized. Instead of measuring the gap between the slots, measure from left-side-of-slot-A to left-side-of-slot-B so the size of the slot doesn’t matter.

Cutters are fine, edge to edge is 1.73. Spindle flex is 0.002". Step distances are still well off from what I’d expect.
