All the manuals claim pulses/mm however, on my parms page it clearly says pulses/unit. I've set my units to inches (#115). I have to following pars set:
50 pulses/unit (200 steps/4mm lead)

Running this code:
G20 (imperial)
G91 (incremental)
G0 Z-.100
M30

I get .0025" movement.

Does my firmeare rrquire pulses/inch since I set imperial, or is it still pulses/mm?  Either way, it doesn't work out. Never had this problem with grbl.  Help!!!!!!!
