HDZ calibration

Hi,
I just recently got my HDZ and installed it… great piece of hardware.

My question now is do I need to calibrate my Z axis with the HDZ. I known there is not belt stretch but just want to be sure I am not missing something like tolerance of the ball screw or something with the stepper…

I was looking in the forum but did not find anything regard HDZ and calibration.

Thanks

In theory, you can calibrate the HDZ the exact same way as you would the stock Z or any other axis (cutting a pocket of a given depth, measuring it with a caliper, and adjusting $102 accordingly).

In practice it is likely that when you do this, you find out that the precision is already very good with the default value (on my machine that’s $102=320), and you might as well stay with the nice round value to avoid rounding errors

Cut a few pockets/steps and you will know.
