Greetings altogether. My problem is so simple and yet I tried everything and no solution.

My linear scales are from ISKRA and they are 5um and this is 0.005mm (the seller told me that they are 0.5Um and now I found out they are 5um)
Anyhow, I have to set two parameters one is in the section Mach3-Config-Motortunning-Steps per unit.

Ok I contacted the Support after a month of trying different calculations and numbers and the answer was:

If you use a scale then you take neither ratio nor screw pitch into account.
Your task is to indicate pulses number per 1mm and the scale will help you with it.
 
>>> The resolution of linear scales is: 5µm this is 0.005mm
 
It's very easy:
 
1mm / 0.005mm =  200 steps per

Ok and now what is the Encoder Pulses/Rev: ( mach3-config-config plugins-CSMIO motion controller configuration)


Does anybody know please help.

Best regards
