M112 error, ender 3

What is the problem?

I installed for my brother a bl touch and flashed the firmware.
And I installed octoprint On a raspi.

Looks good, but only one problem:
After bed leveling it stops sometimes the print and I get m112

Does anybody knows the reason?

What did you already try to solve it?

Reflash the marlin firmware

Have you tried running in safe mode?

No. I think it was via sd card too

Did running in safe mode solve the problem?


Systeminfo Bundle

You can download this in OctoPrint's System Information dialog ... no bundle, no support!)

Will give it later. Not at home during

Additional information about your setup

OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible


The systeminfo bundle would be of enormous help.

Please attach the file to your next post.

thank you
here is the bundle

There may be other reasons for M112, but the one I have seen is the bed was not level. Try manually levelling the bed first, then let the probe do the mesh. I think there is a maximum deviation of a couple of mm on the bed, then it will throw an M112 shutdown error.
