Fans with RRF3



  • Hi all,
    Trying to prepare for the upgrade to RRF3

    In the config.g on my Cartesian i3 steel Duet wifi 2.05

    ; Fans
    M106 P0 S1 I0 F500 H-1                     ; Set fan 0 value, PWM signal inversion and frequency. Thermostatic control is turned off  (Part cooling fan)
    M106 P1 S1 I0 F500 H1 T40                  ; Set fan 1 value, PWM signal inversion and frequency. Thermostatic control is turned on (Hotend fan thermo controlled) 
    M106 P2 S125 I0 F500 H-1                   ; Set fan 2 value, PWM signal inversion and frequency. Thermostatic control is turned off (PCB cooling fan @ 50%)
    

    I have fan2 as the PCB / stepper drivers cooling fan and set to 50% for lower noise . Has being working fine for over 2 years

    From what I've read i need the following in my RRF3 config file to achieve the same

    ; Fans
    M950 F0 C"fan0" Q500                           ; create fan 0 on pin fan0 and set its frequency
    M106 P0 S0 H-1                                 ; set fan 0 value. Thermostatic control is turned off
    M950 F1 C"fan1" Q500                           ; create fan 1 on pin fan1 and set its frequency
    M106 P1 S1 H1 T40                              ; set fan 1 value. Thermostatic control is turned on
    M950 F2 C"fan2" Q500                           ; create fan 2 on pin fan2 and set its frequency
    M106 P2 S125 H-1                               ; set fan 2 value to 50%. Thermostatic control is turned off
    

    Does that look right to you guys ??
    Thanks in advance

    Looks ok.

    You could also use S0.5 for 50%
