I am getting horrible "zits" or "blobs" all over my prints caused by random pauses that are not planned, so no retraction or z-hop, and it appears to be mostly on walls. From watching the terminal and looking at the logs it appears it occurs whenever this message posts (I can visually tell this is what's causes the pauses).
Communication timeout while printing, trying to trigger response from printer. Configure long running commands or increase communication timeout if that happens regularly on specific commands or long moves.
I've not been able to decern a pattern for when it occurs, all of the plug-ins I use were one's I used in the past, but I'm guessing it's one of them since the issue does not occur in safe mode. On a 7 hour print there were probably 200 zits on the inside/outside walls.
FWIW, I recently had to start from a fresh load of Octoprint and plug-in installs. The printer (Ender 3 Pro) ran pretty flawlessly for a couple of years, but I had not used my printer for a few months (basement remodel) and when I tried to bring the system back up nothing would happen. Actually, anytime I shutdown the Rpi now, even with a clean shutdown command, if I then cut physical power to it the device Octoprint will never fully boot back up and it requires me to reload everything and restore from octoprint backup (native B&R). I think that issue is totally unrelated to the zit/blob though, so I plan to open a separate issue for that.
I've search the forums/reddit exhaustively and tried adjusting Octolapse settings and then totally disabled Octolapse, as the forums lead me to think that was the cause but it's still occurring.
I've also tried different USB cables and power adapters, even isolated the printer by itself on a house circuit to try and rule out electronic interference or cable/plug hardware issues, and none of that fixed the issue (note, every cable/plug setup I tried required me fully reloading/restoring Octpi due to other issue noted above, so I've spent a lot of time trying to troubleshoot this issue).
Yes, which is also why I feel like it's not a cable/HW issue.
