Restart forced after prime blob

Midway through a print my printer haulted and seemed to do a firmware restart, gcode fans stopped, unable to connect to the web interface exc. Now whenever I start a print it gets to the prime blob and then haults. I reverted back to my earlier config, updated everything and checked my wiring with nothing unusual happening. Attached is my klipper log and a download of my gcode file. I'm inexperienced with klipper but I don't see anything unusual. No error is thrown it just restarts.

My heaters still work, all my endstops, probes and sensors work fine and motion seems to be working perfectly fine. I have no idea what would be going on. My setup is mostly unmodified with a btt octopus pro f446 and a raspberry pi 4b powered off the rgb header of the board.

This looks really strange, everything just dies. If i had to guess i'd say it looks power related. the Octopus 446 stalls and then the RPi dies. It might be a short caused by a loose connection that only triggers at specific points on the bed, or a brown out. Try powering the pi with 2 x 5v and 2x gnd off the Raspberry Pi header and make sure the 5V USB Jumper isn't in place (needs to be taken out).

5v usb power wasn't in place and I swapped my wiring to match the diagram but the problem persists. I'm going to change the usb cable next but I doubt that's the issue

If the pi actually shuts down, i can't think of anything else than something power related. Really odd.

Unless it's a thermal shutdown

check if there's anything in /var/log/syslog

I'll give it a shot, pi temp never reads more than 50c I'll put a fan over it and see what happens. It looks exactly like a firmware restart, everything clearly still has power but all the outputs on the board shut off.

I couldn't find any file named syslog but I'm not very experienced with Linux file structures. There was a mainsail error file from last night but it looks like my wifi just blipped for a minute.

So the pi is still on?

The pi is still receiving power at very least. I'll take a video of what happens when it shuts down

Everything comes back on after around 2 minutes

I’ve never seen anything like it

Figures I'd run into an issue like this. Are there any files I should post? I've plugged the printer into different breakers and tried externally powering the pi with no success. I might set bed temp to zero and see if that changes anything.

After that I'm just going to reinstall ratos

loganlucklessOP•12/18/22, 9:32 PM

I downloaded my cfg file and reinstalled the v1.2.4 latest non prerelease firmware and it seems to be working. Attached is my cfg file in case any clues could be in there. My ratrig is custom designed so the sizing is a little weird, assuming that is not the problem.

That is one of the most vanilla printer.cfg's i've seen in a while, nothing sticks out. Makes no sense to me that a reinstalled worked. Best i can think of is file corruption or something, but i can't imagine how that wouldn't fail on startup. The weird part about your log is that there's a whole bunch of null bytes inserted when it happens, no errors or anything.

miklschmidt•12/18/22, 9:49 PM

Happy you got it working though

I jinxed myself it happened again

Oh no

miklschmidt•12/18/22, 9:49 PM

So not file corruption then
