"G-Code buffer 'file' length overflow" mid print

  • Hi!
    I'm having an issue with a duet 2 Wifi and I believe firmware version 2.0.
    In the middle of a print it stops and displays the error message in the title. A few minutes later it continues printing however extremely poorly. I dont know what the problem could be. Unfortunately I (who assembled the machine) am in a different place so I have to get the info via text from a friend who uses it in his business. The test pieces that I printed (smaller stuff) all went ok but I know that the guy using the printer uploads very large gcode files. I dont know if that has anything to do with it but it might. We also thought that the sd card might have a problem but honestly we are just guessing.

    The printer is a corexy Hypercube Evolution.

    Thanks in advance.

    ps. sorry about the crappy english. It's not my first language.

    More information is always helpful.

    Can you get an exact error message?
    What firmware version exactly?
    Can you provide a sample gcode file that causes the error?
    Can you get a M122 diagnostic report?

  • Unfortunately not. If I had access to the printer I could provide more info but I don't and my friend isn't really capable of debugging.
    We suspected that the sd card might be acting up (it isn't the one duet sends).
    The firmware is 2.0.0 if I remember correctly.
    The gcode is generated in PrusaSlicer and the problem occurs mid print. So gcode should be fine. I printed a million calibration cubes when I was there just fine.

    We will try this and see if it helps: https://duet3d.dozuki.com/Wiki/Network_disconnections_after_uploading_large_files
