Communication timeout while printing, trying to trigger response from printer

Print stop close to finish and only happens on large files, last time happened on a 8 hours print.

What did you already try to solve it?

  • Changed my Raspberry Pi 4 from a phone charger to a rpi 4 charger.
  • Upgraded to latest version

After looking at your logs, it looks like the printer just plain quit communicating. There doesn't appear to be any unusual events that might have caused it.

Maybe a lose USP plug
