Internal error on command:"CALIBRATE_Z" Internal error on command:"BASE_CALIBRATE_Z"

Quad gantry level works fine.

I start the calibrate_z it starts probing on the Z endstop with and without the probe. Then the moment it touches the bed. klipper crashes.

Is this the only error in your log? And this error is repeatable?

[BelgarionNL]

Exception in flush_handler Once the underlying issue is corrected, use the "FIRMWARE_RESTART" command to reset the firmware, reload the config, and restart the host software. Printer is shutdown

yep every single time. the moment the clicky probe touches the bed for z calibration its dead.

reinstalled klipper on new sd card + updated the skr boards with the latest klipper.

klippy (5).log config-20230602-225305.zip

I thought it had something to do that I dont probe my bed because its glass so its always flat.

You also had this error in your dockable probe extension. I don't think this is related to z calibration.

I found this:

  File "/home/pi/klipper/klippy/stepper.py", line 228, in generate_steps
    raise error("Internal error in stepcompress")
stepper.error: Internal error in stepcompress

and this error:

  File "/home/pi/klipper/klippy/stepper.py", line 180, in note_homing_end
    raise error("Internal error in stepcompress")
stepper.error: Internal error in stepcompress

Here is a first starting point on this: https://github.com/Klipper3d/klipper/issues/4097

[BelgarionNL]

I cleared the klipper log and ran calibrate_z once. klippy (6).log

[BelgarionNL]

you were correct. I tried the new dockable_probe (https://klipper.discourse.group/t/reviving-the-dockable-probe/4256/51) instead of the one I had been using for years from mental.

reverted back to old one and it works fine.

Confirmed this is the case, and mentioned in their PR. Mental's module works fine so this is an external issue.

Is this still a problem? I had unfortunately forgotten the PR regarding the trial session on the develop branch. However, it is now released. But I'm not sure if this is somehow related to this :thinking:
