OK, back to start. It seems we misread the logs and followed a red herring.
As @nefelim4ag noted:
- In each log the initial shutdown reason (and only this counts) is
Shutdown due to webhooks request
. As you noted, initiated by yourself - The
stepcompress
errors are a consequence of this and are to be disregarded
→ There is no Klipper relevant error
Further:
- The Cartographer probe seems pretty unproblematic, judging from the reports here
- Klipper is very sensitive when it comes to violating its axes limits when properly configured. See Move out of range: X Y Z [E]
- You noted something about a strange noise. This would rather point to a mechanical problem
