G codes not uploading to duet wifi



  • I'm having trouble uploading g code files to the duet wifi.
    I tried a new SD card and did the M122 code and saw that my connection is low but it should work.
    Sometimes when I try to upload a file it loads 100% and then gives an error or it gives an error 2 seconds after I try to upload it.

    Do you guys have any idea how I can fix this??

    Can you post the results of your M122 please?



  • Here is the M122 of my printer. It worked fine until i moved it into another room. Could that be the problem? I also fully installed the cover on my duet wifi board.

    Thank you for your time and trying to help me 🙂

  • @Fvanp -72dBm signal strength maybe a bit on the low side for a stable connection.
    Ideally, you'd be after something more in the 40s or 50s



  • I will try to move the printer back to the other room and try if the uploading works then. Sadly enough the printer is a bit to big to stay in the room with my router



  • @Fvanp you could look at either a WiFi repeater or power line adapters with built in WiFi. That should sort you out without having to move your printer.

    Or if you're feeling very adventurous, change the onboard ESP to an ESP-7S and then use an external antenna.



  • @jay_s_uk It is indeed my wifi, I tried it near the router and it worked fine. So I think I have to buy a wifi repeater. Thank you for your help sir.

    You may find that changing the WiFi channel used by the router helps.
