Can't upload gcode files - Duet Web Control

  • Hi, when I try to upload gcode files it gives me an error, the speed is reduced to about 7.4 KiB/s and it gives me an error message. I don't think it is the wifi connection nor the SD card. Any idea? It is the first time using this DUET wifi board, I am using 2.02 release with duet web control 1.22.6 and duet wifi server 1.22. I can't control the machine via the DWC but the only thing I can't do is upload gcode files. Any help? Thanks in advance.

    Can you send M122 in the console and post the results here?

    That's borderline for wifi signal.

    Is the Duet blocked by any metal printer frame?

    If possible, relocate either the printer or the router so they can be closer together to test for better signal strength.

    Ok, so you think it is for that reason? The printer is a bit far from the modem, yes. I will try relocating it, thanks for all. But it is normal that all works good but the files upload only? Thanks

    The transfer speed of the upload will suffer greatly if the router and the Duet can't establish a good connection. It will try and drop the speed to improve transfer reliability, but with the usually large multi megabyte gcode files there is a good chance that they will error out at such a low transfer speed.

    If you find that a stronger connection solves the problem, but you can't easily relocate the router or the printer, possible solutions include adding a wifi repeater or router in the same room as the printer.

  • I had this problem once, and it turned out the microsd card was not properly seated in it's slot. Just removing it and reinserting it making sure the retaining mechanism engaged fixed it for me.

    You should still try to improve the wifi coverage as suggested. My printer currently resides at the edge of the covered wifi area, and it surely leads to performance issues (even with the Duet Web Control) when additional blocking factors (like people moving around or the printer frame being between the laptop and the access point).
