Cannot read file, error code 1

  • Hi, Recently I added a heated bed to my printer. the heated bed works fine but now the printer stops printing randomly and relaying the message: Cannot read file, error code 1. Cancelled printing file Y-carriage_MGN9-H_MOUNT.gcode, print time was 0h 22m. It happens with any gcode file. And when I restart the print, it stops a the exact same point and with the same massage.

    I thought it was a corrupted sd card, so i replaced it, but the problem still persisted. Updating Firmware didnt work either - resulted in even more problems.
    While trying to dowload it via the web interface it stops about where the print stopped, followed with the duet losing connection.

    Does anyone have a clue as to what is going on? Or am I doing something wrong?

    Firmware Electronics: Duet Ethernet 1.02 or later
    Firmware Version: 2.01(RTOS) (2018-07-26b2)

    Normally I would say that message means a faulty SD card or a fault in the SD card hardware. But the fact that it happens at the same place every time is odd. So I am wondering whether the firmware on your Duet is corrupted. Try installing firmware 2.02RC2 from

  • Hello again. I dont think the firmware was corrupt since i reinstalled it many times to counter this issue. What I've done now, is empting all the old gcode files. I had like a GB of gcodes on the SD card. I have tested the last couple of days to see if it happens again, but so far it works normally.

  • @xenjamo I tried cleaning on mine and this doesn't help at all. Probably QC issues with card readers.


Looks like your connection to Duet3D was lost, please wait while we try to reconnect.
