Defiantly a 23 tooth pinion

32.82 Dia Pinion (digital Gauges so may change each time lol i will also try a normal set in case these are off.)
93mm Travel now lol (Hard to get to the pinion to mark it, but i would rather go with this measurement)

OK so now im confused. i punched these numbers into software, however, when I want to move 50mm (In MDI) im getting something like 267mm when marking the gantry and measuring

OK, go back to basics.

Set the steps/mm to 100, mark the big pulley/pinion, and command a move of 80mm (8000 steps).
Does the pulley/pinion move one complete revolution?

Ok that was just over quarter of a turn

With the same 100 step/mm setting, try a move of 16mm and see how far the motor itself turns.

I'm getting multiple turns from 16mm! Lol it still hasn't stopped yet

Ok I'm getting 1 revolution on the small pinion attached to motor. @ 16mm movement with 100spr

So that tells us the microsteps are correct, as with those settings and distance, the controller is sending 1600 steps.

Are you sure the 18:90 gearing is correct for the pulleys?
And everything is moving smoothly and not stalling?

Just thinking of possibilities:

Are you sure it only rotated 1/4 turn? Not 1 1/4 or 2 1/4 etc,
as you previous test seems to indicate too much rotation not too little i.e moves 267mm instead of 50mm.

Also are you sure the leadshine driver pictured (1600 steps/rev) is the one driving that motor?
Could one of the others be driving it and have different microstepping settings?

All motor switches are the same apart from Z
