      I don't know what is happening, I plugged the heater in the "OUT 1" but the Duet 3 is not giving power when I set a temperature in the DWC.
      I measured the wires, it gives me 4 ohms (when the printer is off).
      I turn on printer, and set a temperature, and I measure for volts, and nothing, 0 volts.

      Here are my settings for the nozzle heater:

      M308 S1 P"temp1" Y"thermistor" T100000 B4138
M950 H1 C"out1" T1
M307 H1 B0 S1.00
M143 H1 S280

      The thermistor works because it shows room temperature, and when I heat the nozzle (with a soldering iron for example), then the DWC shows the temperature rising

        Since my previous post, I also tried to connect to OUT 2 and changed "M950 H1 C"out2" T1", and it still did not work.

        To make sure that my heater is OK, I connected the heater wires directly to 12V of my power supply, the heat was going up pretty fast, and the DWC was showing the temperature going up also.

        Forgot to show my board firmware in my previous post:
        FIRMWARE_NAME: RepRapFirmware for Duet 3 Mini 5+ FIRMWARE_VERSION: 3.4.5 ELECTRONICS: Duet 3 Mini5plus WiFi FIRMWARE_DATE: 2022-11-30 19:41:16

        Please help! i'm out of ideas

          New Update:
          When I issue command "M109 S100" it works! it's heating up!
          But! when I select the temperature from the drop down menu in DWC, it does not work!

          What M code does DWC send when selecting a temperature ? how do I edit that ?

            It sounds like you just don't have the tool selected.

            Please post your full config.g.

            Does your DWC version match 3.4.5?

                I suggest you upload this zip file for 3.4.5 to ensure you have everything up to date.

                https://github.com/Duet3D/RepRapFirmware/releases/download/3.4.5/Duet2and3Firmware-3.4.5.zip

                Then add T0 to the end of your config.g so that your tool is selected at startup.
