Max. number of Fans, Duet2Wifi + Duex5

Chuckonelli

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.

@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 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)
