Hi

I have a one problem and 2 logs for the same problems in my printer It appears to me Klipper state: Disconnect and
Klipper reports: SHUTDOWN
Lost communication with MCU ‘mcu’
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

Sometimes it appears to me after 4 hours, 8 hours, 12 hours or more.

I changed the cable connected to the printer and mcu serial in ( by-id to by-path ) Nothing has changed.

See line 601 file 1.

Did you try any of the suggestions in the link @Sineos posted?

Yes I tested the internal power supply of the printer and the power of the sonic pad is all stable and full and I do not have a camera or other device connected to the sonic pad

It suddenly shuts down, whether it is idle or printing.
