      Hello Dear Members

      I'm currently building my own toolchanging Motionsystem (https://hackaday.io/project/175489-changer-a-toolchanger-new-interpreted)
      and I have a qustion about the max. number of fans which can be defined with a Duet2Wifi and a Duex5.

      My current Configuration:
      ; >Fans<
      M950 F0 C"e1heat" ; Air-Pump on E1-Heater-terminal
      M950 F1 C"fan1" ; Radiator-Fan on Fan1 (Duet2_Wifi)
      M950 F2 C"fan2" ; Exhaust-Fans (2 parallel) on Fan2 (Duet2_Wifi)
      M950 F3 C"duex.fan3" ; Partcooling Fan Tooldock D0
      M950 F4 C"duex.fan4" ; Partcooling Fan Tooldock D1
      M950 F5 C"duex.fan5" ; Partcooling Fan Tooldock D2
      M950 F6 C"duex.fan6" ; Partcooling Fan Tooldock D3
      M950 F7 C"!exp.heater7" ; Watercooling-Pump on E6-Heater
      M950 F8 C"duex.fan8" ; LED-Light on Fan8 (Duex5)

      M106 P0 S0 C"Airpump" ; Air-Pump
      M106 P1 S0 C"Radiator" ; Radiator-Fan
      M106 P2 S0 C"Exhaust" ; Exhaust-Fans
      M106 P3 S0 C"PCF-T0" ; Partcooling Fan Tooldock D0
      M106 P4 S0 C"PCF-T1" ; Partcooling Fan Tooldock D1
      M106 P5 S0 C"PCF-T2" ; Partcooling Fan Tooldock D2
      M106 P6 S0 C"PCF-T3" ; Partcooling Fan Tooldock D3
      M106 P7 S0 C"Waterpump" ; Watercooling-Pump
      M106 P8 S0 C"LED" ; LED LIGHT

      With this configuration I only have the partcooling fans for my toolheads. For fan connections I've still have some unused Fan-outputs:

      Duet2Wifi:

      • Fan 0
      • E0 Heater
      • optionally: Always on fans, 2x

      Duex5:

      • Fan 7

      So basically I should be able to configure three additional fans to run the thermostatically controlled heatsink fans on Fan 0, E0 Heater and Fan 7 and just have one heatsink always on.

      Basically:
      M950 F9 C"duex.fan7"
      M950 F10 C"e0heat"
      M950 F11 C"fan0"

      M106 P9 S0 T50 H...
      M106 P10 S0 T50 H...
      M106 P11 S0 T50 H...

      Am I missing something? Is eight the max. numbers for fans on my setup (Duet2Wifi and Duex5)? If so what are my options to run my four missing heatsink fans (temp. controlled)

      I'm looking forward to hearing from you guys.

      Simon

        @chuckonelli on Duet WiFi/Ethernet you can configure up to 12 fans in RRF3.

          @dc42 Thank you for your answer.

          I finally got it working. I'm not sure why it first didn't worked (I assume that I somehow did something wrong in the sequence of the commands earlier)

          Just for disclosure:

          M950 F0 C"e0heat" ; Air-Pump on E0-Heater-terminal
          M950 F1 C"e1heat" ; LED-Light on E1-Heater-terminal
          M950 F2 C"fan2" ; Exhaust-Fans (2 parallel) on Fan2
          M950 F3 C"duex.fan3" ; Partcooling Fan Tooldock D0
          M950 F4 C"duex.fan4" ; Partcooling Fan Tooldock D1
          M950 F5 C"duex.fan5" ; Partcooling Fan Tooldock D2
          M950 F6 C"duex.fan6" ; Partcooling Fan Tooldock D3
          M950 F7 C"!exp.heater7" ; Watercooling-Pump on E6-Heater (Duex5)
          M950 F8 C"fan0" ; Heatsink Fan Tooldock D0 on Fan0 (Duet2)
          M950 F9 C"fan1" ; Heatsink Fan Tooldock D1 on Fan1 (Duet2)
          M950 F10 C"duex.fan7" ; Heatsink Fan Tooldock D2 on Fan7 (Duex5)
          M950 F11 C"duex.fan8" ; Heatsink Fan Tooldock D3 on Fan8 (Duex5)

          M106 P0 S0 C"Airpump" ; Air-Pump
          M106 P1 S0 C"LED" ; LED LIGHT
          M106 P2 S0 C"Exhaust" ; Exhaust-Fans
          M106 P3 S0 C"PCF-T0" ; Partcooling Fan Tooldock D0
          M106 P4 S0 C"PCF-T1" ; Partcooling Fan Tooldock D1
          M106 P5 S0 C"PCF-T2" ; Partcooling Fan Tooldock D2
          M106 P6 S0 C"PCF-T3" ; Partcooling Fan Tooldock D3
          M106 P7 S0 C"Waterpump" ; Watercooling-Pump
          M106 P8 S0 C"Heatsink D0"
          M106 P9 S0 C"Heatsink D1"
          M106 P10 S0 C"Heatsink D2"
          M106 P11 S0 C"Heatsink D3"

          Thank you for the quick help.
