Nema34 - DM860A Driver & Mach3

OK, so X and Y are belt drive and are a different problem.

On your Z axis you say M10 screw. Do you mean a piece of threaded rod with the normal coarse pitch of 1.5mm?

If this is so then on your Z axis 200 steps -> 15 (driving pulley)/20 (driven pulley)x 1.5 mm of movement = 1.125mm, so steps per mm is 200 / 1.125 = 225 (note this is steps per millimetre). If you then use microstepping, you will have to multiply that by the factor you set in the driver DIP switches. (other forum members - could you check this as I am tired today, I have done some work and I am not used to it )

I think you make an error... because the result of 200/1.125 is not 255 but 177,77 ... BUT 200 X 1.125 is 225... so is the calculation or the result wrong?

Anyway I confirm the accuracy of the movements of the Z axis with the values set at 533.33 as described in the previous post ...

It is 200/1.125 but I did say I was tired.
