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

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.

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.

@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

@Via thanks, I will look into that data later.

dc42

@Via, please post the config.g file that you were using with 3.2beta3.2 when that assertion failure occurred.

Do you have any filament monitors configured? [Edit: from your M122 report i think that you do not.]

Via

@dc42 Thank you.

Config attached, not been changed from assertation failure (or from 3.1.1). No filament monitors.

config.g

Via

@dc42 any update on this?

dc42

I wasn't able to pin this down, except to say that it looks like random memory failure or corruption. Please upgrade to 3.4beta4. If it happens again, please post the print file and config.g if you haven't already (I'm using a tablet, so I can't tell), also daemon.g if you are using it.

Via

@dc42 Failed again on beta4 (M122 at bottom) they are posted already but will group together here.

dc42

Thanks for your new report. I am fairly certain that the memory protection fault was caused by a hardware error, because there is no way that the instruction at that address should fault, nor any way that the faulting address should be zero. So I suggest we swap your board. Who did you purchase it from?

Via

@dc42 thanks for your time looking into this. Purchase was from E3D but I have just gone over the 6 months now (purchased 13th May), will you be able to authorise warranty replacement as reported prior?

dc42

Yes I approve a warranty replacement.
