        @arnold_r_clark try tuning as a tool rather than a heater. E.g. M303 T0 S240

            @arnold_r_clark try reducing the M307 R parameter, for example to 0.4 or 0.35.

            Regarding the DHT22, is it a genuine one? See https://docs.duet3d.com/en/User_manual/Connecting_hardware/Temperature_connecting_DHT#choosing-a-dht-sensor

                      @arnold_r_clark the code has changed in 3.4.0 firmware and DHT11 support has been removed, but DHT22 is working for me on MB6HC spi.cs1:

                          @arnold_r_clark have you connected a pullup resistor between the DHT22 signal wire and the +3.3V supply to it? I have a 10K resistor connected to mine.

                          We don't currently support any other humidity sensors, but we may support BME280 in RRF 3.5.

                                @arnold_r_clark that looks OK so I don't know why it isn't working. Which country are you in?
