Basic Information:

Printer Model: Custom Ratrig
MCU / Printerboard: Octopus 11
klippy.log (238.4 KB)

Describe your issue:

Klipper/Firmware restart is not working correctly.
If i Restart firmware i get the Printer is not ready state, klippy host software is attempting to connect.
This Screen never goes away, no matter how long i wait.
If i restart klipper manually after a firmware restart i got error “MCU ‘mcu’ shutdown: oids already allocated” or “Failed automated reset of MCU ‘mcu’”

sometimes it works, most the time not, sometimes it helps to wait 5 minutes or so and then restart klipper.

the only message i really see is “Got error -1 in read: (11)Resource temporarily unavailable”

someone know why my restarts are so inconsistant?

There’s a thread here suggesting that such errors could be caused by the ModemManager package. Maybe check into that first?
