Hello @alfa !

Can you explain what problems you exactly have?

Error messages?
Misbehaviour?

i can’t calibrate the z-axis. mesh test no good. printhead is digging in the bed. whe i try to calibrate mesh it stops and message “No trigger on probe after full movement” the z motor is trying to punch my bed with a lot of noise. my klippy log:
klippy (4).log (4.9 MB)
the print head is pushing the bed down.

Is your probe set at the right height? Are the offsets correct in your cfg? If you home z, can you touch the tip of the probe to make it trigger as it’s moving down, and does it continue to dig into the bed or does it move back up?

Closely and systematically check your config against the relevant example config here: https://github.com/Klipper3d/klipper/tree/master/config (mind your Ender model) and the relevant pin settings for the SKR E3 board also listed there.

I’d be very surprised if

[stepper_z]
...
rotation_distance = 4
...

was correct.

Then:

hey, thank you all for the info. first i changed [stepper-z] to rotation distance:8.thank you Sineos. then i started measuring the probe height. Thanks Zimmystar. seems that theprinted cr-touch holder was no good…probe too high. added some spacers at the probe lowering the height. 1 problem solved, printhead is not digging my bed anymore. still one problem now when calibrating mesh it stops after 4 steps…and generates an error: Move out of range: 236.000 32.000 10.000 [0.000]
can’t find what’s the reason…
So far so good, i am closer to a solution with your help. Greetz Albert

See Move out of range: X Y Z [E] for an explanation and Understanding X and Y Axes Limits and Homing for an approach how to define this correctly.
