Random Resets - Gcode Spin Loop



  • Lately when printing from my external SD card (in a 12864 display) the printer resets at random times during the print. It seems to stop in it's current position, and stay there while it resets itself. This shuts off my power supply relay, shutting down the machine. All is good when I put power to the Duet again.

    Here's a M122 dump just after restarting it, and the SD card logging shows nothing relevant. It seems to only have this issue when printing from the external SD card.

    It's not a big deal, as I don't print from the external SD card often, but it did waste about 1-1/2 days of print time (and filament 😃 ) and I thought you might be interested in a bug report.

    I know the firmware isn't the latest, but it's been working well for me.

    Thanks!

    Except for the random crashes you mean.

    Please update to the 3.1.1 release that's out now. Far too much has changed with fixes and such to be able to support such an old release.

    Yeah! 😛

    I'll upgrade. I thought you might be interested in the bug report, even though it is an older version.
