Hello everyone.
I’m newbie to printing and just installed clipper. Following errors constantly appear:

!!!
Klipper reports: SHUTDOWN

Shutdown due to webhooks request
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

OS - Debian 11.
I installed klipper and other packages through Kiauh.

I see errors in log:

First time i have same problem with mcu-service like in this topic:

Thank you for reply.
Maybe I don’t quite understand correctly, as I’m not an english speaker.
So, this situation normal ?

Is it possible to somehow remove command (M112) if it is sent automatically and is it necessary?
I didn’t find where exactly to do that…

I’m not sure what you intend to achieve.
This button or the M112 command is an emergency shutdown: It makes sure that the printer is

  • shutdown as fast as possible
  • put the machine in an safe state, e.g. turn off everything
  • prevent accidental or intentional reactivation without resetting everything

Just a strange situation.
Many people I know have same printer and installed klipper according to the same instructions and they do not have such nuans and notifications.
But if you, as a person with experience, say that this is normal, then fine.
Then I won’t worry about it.
Thank you.
