Can not connect via WiFi after update to 1.21



  • transferred from another thread, hoping for some help.

    I was running rc4 and have updated to 1.21. I expected this to just work.
    I uploaded the Duet2CombinedFirmware.bin, DuetWiFiServer.bin, iap4e.bin and DuetWebControl.zip files. When the duet rebooted it could not connect.
    The USB printer interface connected to the printer so I tried to run M997 S0 to install the firmware again but this did not work.
    I then erased and reset the board and used BOSSA 1.18 to install, so device manager shows Duet 2 WiFi or Duet 2 Ethernet 3D printer control electronics (COM5)
    Then reset the board and connected the USB again. The printer is online but when I send M997 S0 I get the error Can't read from printer (disconnected?).
    I have followed the Fallback procedure instruction on https://duet3d.dozuki.com/Wiki/Installi … g_Firmware

    I am now stumped How can I resolve this?

    This is the result of M122 after disabling M552 S1 in config .

    @appjaws:

    The printer is online but when I send M997 S0 I get the error Can't read from printer (disconnected?).

    That's normal because the USB port has to be closed to do the firmware upgrade; although it should print a message first warning you about that.

    Your M122 output shows the wifi module is disabled. So send M552 S0 to enable it, give it a few seconds, then if you run M122 again it should show the wifi firmware version in the network section.



  • Thank you DC, Tried that but it didn't work.
    resolved
    For some reason it appears that the WiFi server had not started.
    re-installed and now all OK.
