Prints Pausing: Connection Interrupted/Unknown msg type 6053

@p8blr thanks for the additional report. It's very different from the first one and again looks like it was caused by a transient rather than a software bug.
Do you have the USB port of the MB6HC connected to anything? If so then you may have a USB ground loop, see https://docs.duet3d.com/en/User_manual/Overview/USB_ground_loops.

@dc42 I do not have USB connected. This printer has been running great for months up until now, and nothing has been changed. I have an oscilloscope, is there anything you'd like me to measure?
-
@dc42 It paused again. I've swapped out the 6HC with a spare I had to see if that resolves the issue.
-
@p8blr The printer paused sometime last night with the new 6HC. Since I've already tried replacing the cable, I assume the problem has to be the 1LC toolboard now...

Update. I've swapped out both the duet 3 and toolboard and the printer paused again... I'm going to try swapping out the power supply next. This is very odd because I have two identical printers and one doesn't have this problem, so the power supply is the last variable I can think of...

@p8blr are you absolutely certain that when the printer paused this time, it gave the same message "Error: Board 20 received unknown msg type 6053." ?

@dc42 No it hasn't given that messages any of the last half dozen or so times it's paused. I have no information on the screen, and the console is basically empty, leading me to believe it's being reset.

In that case, please post a M122 report for each board in your system.

@dc42 I will once the printer stops again. After replacing the power supply, I removed all the extra grounding wires and restored the printer back to the original boards. It's been running for roughly 24 hours now, so I'm beginning to suspect the power supply was the issue. I'm going to put the suspected bad power supply in a different printer to confirm.

@dc42 Quick update, the printer is still running, I have an estimated 37 hours remaining on the print right now. Installing a new power supply seems to have fixed the problem. What's odd is that the old power supply is installed in an identical printer and hasn't caused that one to fail yet... I guess this issue is solved, but I don't feel satisfied with the answer lol. I can still send you a M122 on Monday when the printer is finished if you'd like.
