Calibration for Z axis

Hi everyone.

I successfully calibration X and Y axis and drawing the crown on A4 paper also successfully.

How can I calibration of Z axis?



You don’t need to calibrate it. Just check that a 10mm or 30mm move goes nearly that amount. Most errors are 20%, 25%, or 100% off. On the Z I can only think of 2x and 4x errors.

Anything smaller is due to the tolerance on the leadscrew, which is excellent.

How far off was the X and Y?
