General Discussion

Basic Information:

Printer Model: voron 2.4
MCU / Printerboard: octopus v1.2
klippy.log

so I’ve been having this issue and now it’s more frequently before it was 10 hours into a print sometimes five hours and now it’s happening a little bit more often. I’ve tried replacing Canbuss communication wires. Micro usb from U2C to PI, new U2C, new EBB and this is still happening. U2C is on the latest firmware I know that there was a certain firmware that was having issues so I did the update.But I can’t seem to figure this out if someone can please help me.

MCU ‘EBBCan’ shutdown: Missed scheduling of next digital out event

This is generally indicative of an intermittent

communication failure between microcontroller and host.

Good off the cuff analysis.

Too bad you didn’t include the klippy.log that you were asked for in the template so that an in depth analysis can be done.

Unfortunately I can’t provide the log if not I would. But doing some research I’m not the only one with this issue just can’t seem to find a solution and even the the people that provide the logs with this issues didn’t do much justice. Some say U2c,wire etc. But thank you for your feedback

Took the umbilical wire harness out to check for any brakes
