Correction travel distance

loby

Hi, I am trining to setup up the travel distance of the axis. I measured e.g. on the Z axis 0.1 mm to less travel distance if I travel 5mm down. So I want to setup the duet2 to compensate this 0.1 mm in the right way.
I did not find a hint for that how to do. Could someone help me?

Thank you.
Best regards

The right way would depend on what the problem is.

How are you driving the axis, motor, coupling, belt, screw.

An any case its either backlash which I don't think the Duet an compensate for or your effective gearing is a bit off and you need to adjust the M92 steps/mm setting

Perfect! That was the keyword I am looking for. Steps/mm? I looked in the config and didn't recognized the setting. After you named it I saw it immediately.
Now the travel distance is perfect!

Thank you so much for the speed help!
