      Hi guys,

      Im trying to update my firmware from 2.05 to the latest(3.something) and on wifi when I go to install, it says communication lost and when I do it with usb, right after I issue the install firmware command I hear the usb disconnect and connect sound, get no feedback and when I check if I have the latest firmware, it still says the older one.

      Any idea what the issue could be?

          Are you able to connect to DWC at all, or just USB atm?
          If you have USB terminal, send M115 to get the currently installed firmware version.

          To get back on track I suggest you pull the SD card from the duet and use your PC to place these firmware files in the /sys folder.

          https://github.com/Duet3D/RepRapFirmware/releases/download/2.05.1/Duet2CombinedFirmware.bin
          https://github.com/Duet3D/RepRapFirmware/releases/download/3.0/DuetWiFiServer.bin

          Then replace the files in the /www folder with the files from this zip file.

          https://github.com/Duet3D/RepRapFirmware/releases/download/2.05.1/DuetWebControl-SD-2.0.7.zip

          Then put the SD card back in the Duet and reconnect via USB terminal and send M997. This should flash firmware 2.05.1 and wifi server firmware 1.23. Send M122 to confirm the versions.

          Then you should be able to power up the duet as normal and connect via the web interface.

          Once you've got DWC back you can update to 3.0 and 3.1.1 by uploading the firmware zip file packages one at a time, as is, don't extract them first. Upload them to the system tab.

          https://github.com/Duet3D/RepRapFirmware/releases/download/3.0/Duet2and3Firmware-3.0.zip

          https://github.com/Duet3D/RepRapFirmware/releases/download/3.1.1/Duet2and3Firmware-3.1.1.zip

          That should update to 3.0, reboot, and then upload 3.1.1 and reboot again. Send M115 to confirm the firmware version.

          Now you can upload your new config file set obtained from the online config tool for RRF3.

            Awesome, thank you, got it updated. Appreciate the detailed writeup. A suggestion is I'd put that info with the other disclaimers under "Usual procedure" because I didn't read that far down, figured that didn't apply to me. Thanks though. Looking fwd to using these boards!
