        Can you send M122 and M98 P"config.g" and share the results?

        Can you show how you have the fans connected?

        How did you test the fans to know they are working?

        Fan0 should be gcode controllable, or with the slider in DWC, and Fan1 and Fan2 should turn on when heater1 is above 45c based on your config snip.

              @bartekp check the fan fuse

              Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is

                I think you might have sent M112 instead of M122?

                    @bartekp no they aren't supposed to:
                    M112
                    M122

                    Edit: Worded the sentence badly.

                      @Exerqtor Well perhaps more accurately they shouldn't.

                      @bartekp If you are sure that running M122 (not M112) causes a connection lost, then you need to look into that more fully. So for instance: What connection is being lost here? How are yin running M122? Is it via the DWC console, a USB terminal, a panelDue?
