24v fan connection on Duet 2 wifi

Veti

the default setting from the configurator should produce the required config.
did you make any changes to that?

check the wiring diagram.

the fan headers have a v_fan pin which is the red wire and the other is the black wire.

Fan0 is typically the part cooling fan and Fan1 is the hotend heatsink fan.

I connected them here,

they turn on at start-up that of the hotend turns on when it reaches temperature.
But I can't control and / or turn them off.

Veti

post your config.g

Eccoli.

M950 F0 C"fan0" Q500 ; create fan 0 on pin fan0 and set its frequency
M106 P0 S0 H0 T45 ; set fan 0 value. Thermostatic control is turned on
M950 F1 C"fan1" Q500 ; create fan 1 on pin fan1 and set its frequency
M106 P1 S1 H1 T45 ; set fan 1 value. Thermostatic control is turned on

you configured both fans to be non controllable.

change first one to

M106 P0 S0 H-1

Thanks a lots

the new configuration will be like this then

M950 F0 C "fan0" Q500; create fan 0 on pin fan0 and set its frequency
M106 P0 S0 H-1 T45; set fan 0 value. Thermostatic control is turned on
M950 F1 C "fan1" Q500; create fan 1 on pin fan1 and set its frequency
M106 P1 S1 H-1 T45; set fan 1 value. Thermostatic control is turned on

Also I wanted to ask if there is any other optimization I can do for the speech fans.

I was advised to keep the hotend fan off when printing both PLA and PETG. How do you manage them?

i dont think you used the right words here. do you mean noise?

PLA wants cooling.
pets wants a little bit of cooling

That is managed in the slicer fan setting
