More then 3 fans on duet Maestro?



  • Hey Guys,

    I am looking for a solution to controll more then 3 fans with my Duet Maestro. I want the following:

    • Coldend, thermally Controlled
    • Part Cooling, gcode Controlled
    • Chamber, thermally controlled
    • electronics, thermally controlled
    • LED in Heater 2

    I might use some Outputs and external mosfets for that and so on.
    I Control the LED by Just writing to Pin 2.
    But If I want to add Fans past fan2 the Firmware states that the number has to be between 0 and 2.
    Any was to avoid that.

    Thanks

    Yes, use RepRapFirmware 3, which is in beta. Currently it supports up t 4 fans, but I can increase that if it helps.

    PS - I just increase the maximum number of fans on the Maestro to 6 for the next RRF3 build.



  • Thank you David!
    I think I have to Switch to RRF3 in this Case...I knew, this time would come 😛
