What is the problem?
I updated to 1.3.11 via the web interface and updated the pi with apt-get update apt-get dist-upgrade. All of a sudden, I started getting the message:
Communication timeout while idle, trying to trigger response from printer. Configure long running commands or increase communication timeout if that happens regularly on specific commands or long moves."
and my printer will eventually stop printing, but the raspberry pi is still responding and I'm able to ssh into it.
What did you already try to solve it?
I am using a USB cable with ferrites on it. I unplugged the USB cable and replugged it again. I restarted the printer and the raspberry pi. I unplugged my camera from the pi so the only thing connected was the printer. My red light stays bright red and does not flicker. I did another apt-get update and apt-get dist-upgrade, but no more packages were available.
I changed all 3 max consecutive timeouts to 0 to disable them and I got horrible layer shifting. I've currently unplugged the pi and am printing the model from sd card to make sure I have no problems and no layer shifting doing that.
Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware,
serial.log or output on terminal tab, ...)
Running 1.1.9 bugfix Marlin on an Ender 3. Nothing has changed except updating the pi and octoprint.
