Problem with Tool Fan



  • Hi.

    i have a problem with my tool fan...

    I want it to run with 100% after Hotend is over 45°C.

    While printing the fan goes down to 15 like the part cooling fan...

    What did i wrong?

    ; Fans
    M950 F0 C"out7" Q10                          ; create fan 0 on pin out7 and set its frequency
    M106 P0 C"Hotend" S1.0 T45 H1                ; set fan 0 name and value. Thermostatic control is turned on (45°)
    M950 F1 C"out8" Q10                          ; create fan 1 on pin out8 and set its frequency
    M106 P1 C"Radial" S0 H-1                     ; set fan 1 name and value. Thermostatic control is turned off
    
    ; Tools
    M563 P0 S"Mosquito" D0 H1 F0                 ; define tool 0

    How do you have the fans wired?



  • You messed up your fan definitions and terminology. Tool fan is part cooling fan, not hotend fan. As i see from your config, your "Radial" fan is part cooling fan, so you should define that fan with tools. Change F0 in M563 to F1 and try again.



  • Hotend Fan should be named as Heatbreak Fan... Radial is the part cooling fan
