What is the problem?
I am running long prints (24-48h) somewhat after 6 hours the connection between the pi (4b) and printer (BCN3D SigmaX R19) gets lost:
'No response from printer after 6 consecutive communication timeouts, considering it dead."
What did you already try to solve it?
Updating and rebooting both machines and plugins
Logs (octoprint.log, serial.log or output on terminal tab at a minimum, browser error console if UI issue ... no logs, no support!)
