New Voron instance lost communication with EBB (can bus)

@regressor go into the mcu information detail within Fluidd/Mainsail and check for these fields to be zero on ALL your MCUs. If any are non-zero you’ve got a communications issue on your CANbus and you need to check it for problems (loose/dirty connections, bad cabling, termination problems, etc.).

I found mine were non-zero and nefelim4ag just commented on my thread and mentioned this one. I think mine may have been related to CANbus cabling and I’m cautiously trying a spare cable I had on hand which at first blush seems to be working better.

Good luck!
