Nah wrong got it wrong.
You now have distance pinion travels for one rev which is 96.16 but you have 5:1 ratio so this drops to 19.232 for one rev of the motor which is the affective pitch. So now simply divide 1600 by pitch to get the steps per mm ie: 1600/19.232 = 83.194 steps per mm
Doh didn't see MC done it.!Last edited by JAZZCNC; 17-03-2017 at 09:39 PM.

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?Avoiding the rubbish customer service from AluminiumWarehouse since July '13.

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

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?
