Axxis setup, Steps per Unit?

[4.2A]

Hello, I have a question regarding the Axxis setup. My spindles are 16x4, normal Nema 24 stepper motors, stepper drives set to 1600 microsteps.

Steps per Unit: ???

Of course I used the Calibrate function (result=412.371134...), but then 360mm became ~380mm, all measures where too high.


Any idea?

My spindles are 16x4, normal Nema 24 stepper motors, stepper drives set to 1600 microsteps.

If on the motor one turn is 1600 steps and one turn moves 4mm then you need a quarter turn to move 1 unit (mm), so it will be 1600/4=400 steps/unit.

Thank you, works fine.
