Duex 5 PWM Fan Outputs Question



  • Is their a way to make the any of the 6 PWM fan outputs thermostatically controlled. I have one output connected to a LED and would like to have it come on when the hotend comes on.

    Yes, should be doable. I'm using multiple Duex5 fans to cool motors by monitoring thermistors stuck to the motor casing. So all you'd need to do is change the heater associated with the fan.

    e..g. one line from my config.g is this........

    M106 P7 S255 I0 F250 H108 T40:50; Set fan 7 (Right XY stepper fan) to work thermostatically on P108 virtual temp

    So to have the "fan" switch with hot end temperature, you'd simply change H108 to H1 and use the T parameter to select the temperature or temperature range that you want to use.



  • Perfect.
    Thanks.
    That did it.
