      I'm running

      • DWC version 3.3.0
      • RipRapFW version 3.3
      • Wifi version 1.26

      I want to downgrade to RR v2.2 to resolve some issues I'm having with overheating and fan cooling controls.

      I wipe the SD card and install the FW I want.
      I connect via USB and hit M997 S0 to install it and I get the error:

       File 0:/firmware/DuetWiFiServer.bin not found

      Which is because v2.2 doesn't have this file structure. So I looks like I might need to reset the Duet. I'm running a Duet 2 wifi, no reset button, but I see where the jumper is.

      Anyone got any last words of advice for me before I brick this thing?

        Words of advice?

        Don't do it until you explain the problems you are having.

        I have 5 printers all running 3.3 and am having no problems with overheating or fans.

        Frederick

        Printers: A FT-5 with the 713 upgrade bits, a custom MarkForged style, a small Utilmaker style, a small CoreXY from kit and a E3D MS/TC setup. Various hotends. Using Duets (2 and 3) running 3.4.6

          Do you mean v3.2.2 as I don't think v2 firmware got past v2.05_1?

            Have you tried manually placing that file where it expects it?

            Have you tried uploading the full zip file for the version you want to switch to?
