Duet 3 Softwarecrash?
-
Is that M122 right after a crash?
-
@phaedrux Not right after, but there was no other action between. The problem happened more or less at 21.15 (screenshot) and the M122 one hour later.
-
@metty I have added this to my list to look at. If it happens again, please post a new M122 report taken afterwards.

@metty your MCU shows 50+ deg C
Maybe consider some cooling on the Duet 3 board -
@martin7404 Thanks for the hint.. I will keep an eye on the temperature. 50 deg does not look problematic for me, but I am not so familiar with the hardware to be sure.
-
@metty the Duet boards should be ok up to 80 degrees C
-
@dc42 I found the printer today again in the same state. I suspect several hours passed between the crash and the M122:

@phaedrux
It happened again, so stack-overflow for sure? So increasing the stack would be a solution? Or is there any other method to check what was responsible for the overflow?
If I post more 122, I guess you can not read more info's that you already have, is that correct?M122

Can you also provide the gcode file that provoked the crash?

@metty I'm sorry, your issue was on my list to look at but as the information in the M122 report is not a clear case of a stack overflow, I hadn't finished looking into it.
We've just released RRF 3.4.0beta1. It has the same size stack for the task that crashed as in 3.3.0. So I've made another build with a larger stack available at https://www.dropbox.com/sh/razha1aikzytuw5/AAAEZnuoDAtUqklUsSnvNzKHa?dl=0. Please try this build.
If it crashes again, please post another M122 report after the crash. If it appears to fix the issue, please post a M122 report taken after the machine has done a lot of printing, so that I can check on the stack usage.

@dc42 Thanks a lot, for preparing a firmware for me. I can test it in the end of the week. I keep you informed if the crash happens again or not.
@Phaedrux If you want I can share the g-code file. I guess it is difficult to find a problem there. I could not find a pattern of this error. Suddenly it happened. I was printing the same part, with the same code 12 times. Maybe every 4th time it crashed. -
@metty do you have any update for me on whether the new firmware build solved the problem?

@dc42 Thanks to coming back to me. Last days were crazy. Unfortunately, I was not able to print or build anything on the printer last week.
That should be better now. I was just able to install the firmware. Will thus immediately test. Since the error also only occurs sporadically, we will certainly only know in a week whether it has done anything. I will be in touch again! -
@metty we've today released RRF 3.4.0 beta 2. This includes the larger stack size.

@dc42 Nice thanks! So just installed 3.4 beta2
