    Hello,

    yes, it is exactly a piece of M10 threaded bar.

    So for the Z axis I was able to calculate it like this:

    driving-pulley / driven pulley x 1.5mm (threaded bar) the result is divided by 200 (physical steps)
    and in this case it would be just like you wrote:

    15/20 * 1.5 = 1,125mm 1,125 * 200) 225.

    Assuming to set the driver through the dipswitches to 1/4 (400) I have to make 225 * 4 = 900.
    Or if set to 1/8 (800) 225 * 8 = 1800

    This value is what I have to set in the motor tuning section of mach3 for the right Z axis?

    Is this calculation valid even if the pulley on the threaded rod has not been tapped but is held in place by nut-locknut?
    I attached a photo for a better clarity:
