Did you try what I posted to your last post this afternoon?
Really curious to see if this works for you. I checked the numbers and LB does take 6 figures in the steps. This is what my setup would be for microsteps per rotation=6400, 5mm pitch screw, 24" travel:
I would have to move too much stuff around to test tonight but similar setting have worked recently. Might have time to try this weekend.
Based on:
DIP on the microstep driver is 6400 you would need to adjust accordingly.
travel is 24" so even number 600mm.
screw is 5mm pitch=6400 steps move 5mm. 768,000 move 600 mm
