Random loss of the extruder



  • Good morning all

    I have a problem my config works well but I randomly lose the extruder.
    card: Duet 2 wifi
    screen: 5 inches with Paneldue
    printer: Core xy home made
    I indicated several times in config.g T0 but it still ended up not being lost and in a completely random way:
    I was able to print 3 hours and 2 minutes from the end of the print loss of T0
    "Error: Attempting to extrude with no tool selected."
    please help me i love the functions of the duet !
    My configuration :

    Can you share the gcode file you were printing?



  • CFFFP_occhiale_ale_5.gcode

    Thank you for your answer, I have the linked file.

    I did include the T0 in my gcode file but it ended up losing the tools.
    I have a smaller file but it works like no other.

    @seb007 I can't see anything particularly wrong with this gcode file. There are no other tool change commands. Is this the file from the SD card? If not, I think maybe the file on the SD card may be corrupted. This could be caused by an error in transfer, or because of a corrupt SD card.

    Please send M122 to the Duet and post the response. See https://duet3d.dozuki.com/Wiki/SD_Card#Section_Troubleshooting_SD_Card_issues to test the SD card and SD socket.
    What version of DWC are you using? Select Settings > General in DWC to see the version. Are "CRC32 checksums for uploads" enabled? See Settings > Machine-Specific > Communication.

    The gcode files you upload via the web interface end up on the SD card in the Duet.

    So please check the things that droftarts mentions.

    Your DWC version should be 3.1.1.



  • thank you I will test and come back to you
