Reset during print Part 2 - Duet 3.1.1 / 3.2beta3 - Duet3+SBC

Via

@chrishamm apologies, didn't notice 3.2beta3.2 update until I posted this.

I have now updated to this and now for something different... Print got a lot further than previously (Layer 21) and then just froze, this time board did not reboot.

Full syslog at the time

Screen attached to pi has frozen and web connection sits on "Connecting".

Left while writing this post (to save filament waste I am using a modified version now with temps set to 0 so it goes through the motions without actually printing) and after a while it suddenly restarted printing.

Looking at logs (extrusion warning because of zeroed temps) it did last print move at 17:42:55 and then two at 17:45:53 and 17:45:58 (did think I heard it move but when I went to check display was still frozen so thought I imagined it) and then started reprinting fully (and still continuing now 10 mins later) at 17:51:01

The DCS section has nothing (other than the restarting transfer shortly before) - tool not driven warnings removed from all logs for clarity.

Sorry for double posting but an update...

Print is still continuing (almost complete now judging by movements) however rpi gui is totally frozen still (mouse pointer not even moving).

Remote web panel working fine however print status shows as 100% complete on layer 21 (where it froze) status box at top shows busy and is updating correctly though with tool position (have also reloaded page).

If DCS reports many "system time has changed" messages then its internal update task stalled longer than 5 seconds every time. I suspect the underlying problem may be related to the DWS error messages, too, but TBH I have never observed those messages yet.

I noticed bad SD card performance may cause lags and if yours is damaged, those kinds of problems could be expected. I suggest you rewrite the latest DuetPi version to your board, update everything, and then change once again to the unstable branch. Please use the official Raspberry Pi Imager this time and let it verify the written content. When you start this tool, you can select custom third-party images at the bottom of the distro selection and then select the corresponding DuetPi img file.

If the same problem persists, maybe leave htop running in a console in the background after a fresh start and check if a process is taking an excessive amount of CPU or RAM.

Your issues seem similar to mine. I was getting a few different errors

Warning: Tool 0 was not driven because its heater temperatures were not high enough or it has a heater fault

Connection interrupted, attempting to reconnect...
DCS has been stopped

Warning: Lost connection to Duet (Board is not available (no data response))

11/6/2020, 5:21:16 PM	Cancelled printing file 0:/gcodes/a1.gcode, print time was 0h 19m
11/6/2020, 5:21:15 PM	Warning: Controller has been reset

Removing the pi fixed the issue so I'm waiting until the communication issues are resolved before going back to the SPC

@chrishamm that was with the fresh install on a new (Sandisk Ultra) memory card. But I have redone to double check as previously did use Rufus to write. I have used RPi imager this time and verified. All updates done and rebooted, M997 done to confirm all updates OK and shown running 3.2beta3.2.

And this time back to reset ~1hr into print.

Kept a casual eye on htop during print, chromium did sit fairly high on CPU usage averaging ~55% but spiking as high as 98% this is without any plugins installed (did have Visualizer on previous) and only window open on gui is standard DWC.

Nothing telling on syslog (added M302 P1 to get rid of tool not driven warnings)

@dhusolo Just had a look through your thread, looks like that will be the way to go for now which is a shame as whole design of this printer is around the SBC and display design. Did you have any issues going over to standalone? I did try to do that a few days back but having problems getting board to start in standalone mode, most likely not got SD card right as my board only had the old duetpi image (but will do seperate thread on that later if I still have issues).

I am just redoing print now with debug mode as advised in that thread to see if it gives any further insight.

chrishamm

@Via Can you please share your G-code file? The other thread is not related to this issue and that one is likely fixed in the latest beta. Your M122 excerpt reveals that the Duet had an unexpected watchdog reset and it would really help if we manage to reproduce this.

@Via I flashed 3.1.1 to the board with Bossa and made a new SD card config. It didn't take too long

Via

I've put Duet3 into standalone now, retried print using 3.1.1 and print failed again. M122 shows Memory protection fault at time of failure.

chrishamm

I've got more details about this problem, it looks like lxpanel (a program for the desktop running in the background) has a memory leak and which, at some point, causes problems with DSF. I hope this will be fixed by Raspbian soon.

@Via Please try out 3.2.0-b3.2 in standalone mode, the memory protection fault should be fixed in that build.

Via

@chrishamm Thanks for the update.

Would using the non-gui version of duetpi and forgoing connected screen work around this issue for the short term keeping SBC control?

Have updated standalone to 3.2.0-b3.2 and running test again now.

chrishamm

@Via Yes, I think so. My printer has the GUI-less variant installed (DuetPi lite), so that probably explains why I couldn't observe this problem before.

Via

@chrishamm No luck again on standalone with 3.2.0-beta3.2, this time "AssertionFailed"

I will have another try later with duetpi lite.

dc42

@Via , I will look into this later today.

Via

@dc42 Many thanks.

Is it worth trying with DuetPi Lite? Was going to try earlier but work got in the way

dc42

@Via said in Reset during print Part 2 - Duet 3.1.1 / 3.2beta3 - Duet3+SBC:

@dc42 Many thanks.

Is it worth trying with DuetPi Lite? Was going to try earlier but work got in the way

I doubt it. The assertion failure looks like it was caused either by memory corruption, or possibly by a power brownout. I guess a hardware problem is also a possibility.

Can you set up a macro that runs the file in simulation mode within a loop, to see if you can provoke the failure that way?

Via

@dc42 I've ran the file as a normal simulation which completes fine.

Trying to do a macro to loop it but my gcode knowledge is terrible and keep freezing the board can you point me in right direction?

Was thinking this (I know never ending loops are bad in themselves but was just going to let it run until I reset it) but looks like it is just buffering all the M24s in one go how would I go about waiting for it to finish one before starting the next?

M37 S1
M23 "[PLA] CFFFP_Top - ReRender - zero temps.gcode"
while true
	M24

Via

@dc42 Stopped overthinking it and just added the M37/M23/M24 to the end of gcode which is looping properly now.

Has done ~130 loops with no issues in simulation.

Via

Simulation loop ran for 4 1/2 hours (~380 loops) with no issues.

Ripped 24V PSU out of another printer today and unplugged heaters and fans so just steppers and sensors plugged in and done another test print, again this did not complete.

This time M122 back to Memory Protection Fault
