Printer Model: Ender 5+
MCU / Printerboard: Octopus pro 429 V1.0 usb to can host, EBB42 via can

Klippy shutdown, unable to connect to mcu EBBCan
Printer shut down after approx 2 hrs of printing, I tried to go trough the klippy log, but i’m not understanding the logfile.
Can someone see what went wrong?

USB CANBUS bridge 'mcu' is discarding!
Looks like a sort of hardware CAN error.
Maybe there is something happening with EBBCan itself.
As a start, I suggest checking your wiring and monitoring EBB temperature.
I read some posts here concerning “different EBBs and CAN” problems.
In my eyes, the EBB boards lack enough capacitance on the supply voltages.
Good luck, hcet14
I checked all wiring, started a new print, and it failed again but after 7hrs this time, and now it didn’t want to come online anymore.
Checked all again and by wiggeling the connector a lil bit a wire popped out.
It was propably damaged enough to make prints fail, but until that point still attached…
Thanks for looking into it guys!!
