Duet "Crashes" on Print



  • When I upload and print a file my Duet seems to crash. The web interface disconnects and the screen on the printer become unresponsive

    I have checked all the movements, including home
    Heated the bed
    Heated the hotend
    tested the extruder
    Tested the probe
    and everything works ok

    If there any logs I can examine to try and work out what is going on?

    When entering M122 I get

    M122

    Any help / things to look for most welcome.

    The only change I made since it last worked was to add the duex5 to do 3 point bed leveling (I have now removed that (and related gcode) and gone back to 1 z stepper (2 motors) as a point of elimination

  • As an additional test I have also tried printing direct on the duet screen and that also does not start the print.



  • Just to be clear. You can home all the axes, heat the bed, heat the hot end and extrude filament yes?



  • @deckingman Yes, I have full control of the printer and everything works, I just can't start a print



  • @mark That's very odd. Does it do it with every gcode file or just one particular file? I wonder if your SD card has become corrupted. Have you tried a different card?



  • @deckingman

    I have tried a new Benchy and a calibration cube that has been on the card a while and printed previously.

    If I backup all the files on the card and do a factory reset and the issue still persists (once I do a manual setup again), can I just copy the backed up files back on the card to get back to where I am at the moment?



  • An easier test would be to use a new sd card. Copy the contents of your current card over and try the new card.



  • @Phaedrux 👍 will try it out tonight

    Thanks

    @mark, your M122 report indicates that the last software reset was user-initiated, not a crash. This may have been caused by using the Emergency Stop button, or by sending M999, or by upgrading firmware.



  • I figured it out, and am very ashamed to say it was user error 😞

    I accidently uploaded the slt rather than G-code file!

    @deckingman thanks for your input and keep up the good work on your projects, you have a new follower
    @Phaedrux thanks for the advice
    @dc42 Again thanks for responding - should uploading anything else other than a g-code file to print be a valid user story?

    Again thanks all for you inputs

    Mark



  • How did you upload an STL? I've just tried and the file selector greys them all out and dragging and dropping won't take it either.



  • @Phaedrux I can still upload a stl. Maybe I am not using the latest firmware - I need to work out how to update it, but that's a job for another day!



  • Download this zip file https://github.com/dc42/RepRapFirmware/releases/download/2.03/Duet2Firmware-2.03.zip

    Then upload the whole zip file as is to the Settings page in the DWC. That's all you have to do.
