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

    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

    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?

    Yep, defiantly 18 teeth on motor side and 90 teeth on large pulley to pinion

    In that case it is definitely a 5:1 ratio, so with the 100 step setting, the big pulley should turn once with a move of 80mm (16x5).

    Once that's confirmed, work out the tooth pitch. Measure over as many teeth as you can, then divide your measurement by the number of teeth you've measured over, then multiply by the number of teeth on the pinion (23).
    Then that will give the distance one revolution of the pinion should give.

    Then divide 8000 (number of steps for one revolution), by that distance, which should give you the correct steps per mm.

    I've just done a movement with your settings 86.0215 and it moves 55 mm when asking it to move 50. So I'm nearly there.

    Last time I think I mucked up
