Well, according to logs, both sb2209 and scanner show timeout, at the same time.
Timeout with MCU 'sb2209' (eventtime=622.707328)
Transition to shutdown state: Lost communication with MCU 'sb2209'
Timeout with MCU 'scanner' (eventtime=622.707328)
So, looks like a CAN wiring/power issue.
Btw, sounds similar to New Voron instance lost communication with EBB (can bus)
Hope it helps.
