    Hi Guys.

    I have a question about a Duet Wifi 2 and Duet 3 6hc board.
    I have 2 component fans that should start up at the same time.

    How do I enter this under RRF 3?
    Would that be for duet 3 e.g.
    M950 F2 C "out6" Q500
    M106 P2 S1 H1 T50

    Is that for Duett 2 wifi then:
    M950 F2 C "fan2" Q500
    M106 P2 S1 H1 T50

    ??

    Will both component fans start up on the M106 S255?

      H1 T50

      this means the fan turns on if the heater 1 is above 50
      in that case it can not be controlled by m106.

      H-1

      this would mean controlled by m106

        Your question is a little unclear. Are you using a Duet3 or Duetwifi? are you wanting to use 2 fans on the same tool?

          if you are using 2 fans to work on same hotend as aprt cooling fans, I do it, @omni is doing it, many others are doing it for sure, just connect them to the same output, if they are rated as your Vin connect them in parallel, if they are rated as Vin/2 (e.g. your Vin is 24V and your fans are 12V) wire them in series and ideally add 2 100uF across each one. 2 elcos, 100uF each, one across each fan.

            @Veti Yup, as Arhi said - if your fans are rated the same voltage as your VIN run them in parallel. If they are half your voltage, run them in series - and you might want to put a zener diode on each end of the series just to protect the fans. That's how I am using these two beefy 12v blowers on a 24v VIN

                I have config the Firmware with the tool but the both fans not start with M106 S255.

                On the main can i start the Fan.

                ; Fans
                M950 F0 C"out7" Q500 ; create fan 0 on pin out7 and set its frequency
                M106 P0 C"Hotend" S0 H0 T45 ; set fan 0 name and value. Thermostatic control is turned on
                M950 F1 C"out8" Q500 ; create fan 1 on pin out8 and set its frequency
                M106 P1 C"Bauteil1" S0 H-1 ; set fan 1 name and value. Thermostatic control is turned off
                M950 F2 C"out9" Q500 ; create fan 2 on pin out9 and set its frequency
                M106 P2 C"Bauteil2" S0 H-1 ; set fan 2 name and value. Thermostatic control is turned off

                ; Tools

                  both fans not start with M106 S255.

                  Try specifying the fan number with M106 P1:2 S1

                  https://duet3d.dozuki.com/Wiki/Gcode#Section_M106_Fan_On

                  Are you sure both fans actually work?
                  Do they work if you connect them to the always on fan ports?
                  Are they wired to the right ports?
                  Can you control them both independently?

                  In the DWC do both fans turn on when using the Tool Fan slider?

                    @Phaedrux yes both Fans work.

                    Yes i Can control them both independently.

                    In the DWC have i fan1 slider at 100% work fan1 and fan2 slider at 100% work fan2.

                    With M106 P1 S255 work fan 1, with M106 P2 S255 work fan 2 but M106 P1:2 S255 work only fan 1

                      M106 does not support a list of P parameters.

                      To use two part cooling fans on one tool, the simplest approach is to connect them in parallel to a single fan output. However, an alternative is to map them in the M563 command, for example:

                      M563 P0 D0 H1 F1:2

                      Then when tool 0 is selected, M106 Sxx with no P parameter will control both of them.

                          Should be: M563 P0 S"Hotend" D0 H1 F0:2

                          Remove the second F and do not include the thermostatic fan in the M563 command.

                                I think this is the expected behaviour. During a print do both fans work as expected?

                                  Unfortunately not. I can only control Fan2 via the slider in the DWC. With M106 S255, only fan 1 starts, not fan 1 and fan 2 together

                                    In DWC there should be a tool fan slider that controls both.
