How to assign another Fan to Fan0.



  • For some reason my Fan0 F1 and Fan 2 connectors do not drive fan.

    I do have a Duex5, so i have F3,4,5 etc available.

    I am trying to work out how to remap Fano to Fan3 Pins.

    Everything i have tried either gives me multiple Fan control on DWC.

    Even assigning tool to F3:0,

    send a gcode Fan0 does not control Fan3.

    Any suggestions on this please.



  • Please post your config.g so we can better assist you.
    Big difference between RRF2 and RRF3 fan control

    P.



  • This what i had originally
    ; Fans
    M106 P0 S0.3 I0 F500 H-1
    M106 P1 S1 I0 F500 H1 T45

    ; Tools
    M563 P0 D0 H1 ; Define tool 0

    It all was working Fine
    Now my Fan0, FAn1, Fan2 do not work.

    tried running gcodes below

    M106 P3 S255
    M106 P0 S255
    M106 P1 S255
    M106 P2 S255

    Fan 0 Fan1 Fan 2 do not turn on

    But Fan3 does.

    So I chance my config to this

    ; Fans
    ;M106 P0 S0.3 I0 F500 H-1
    M106 P1 S1 I0 F500 H1 T45
    M106 P3 C"Part Coolong" S0.3 I0 F500 H-1

    ; Tools
    M563 P0 D0 H1 F3
    G10 P0 X0 Y0 Z0
    G10 P0 R0 S0

    So if i send M106 P0 S255
    Fan 3 does not turn on, as all my gcode files have that.

    So my original question is how to Remap Fan0 to another Fan within duet Config, not the slicer.

    And yes i would say my duet board has gone faulty, but i should be able to remap fans.



  • In first place i would check out why fan0 - fan2 does not work. Have you checked fan fuse?

    Since you changed it with the tool binding to use fan 3, what happens if you just send M106 S255?

    We're also assuming you're using RRF2, since you haven't mentioned M950 yet.



  • @Phaedrux

    Yes i checked fuse. The always on Fans are working

    Yes RFF2

    M106 S255 has no effect.

    P.S. on Marlin i can remap the pin, can i do something similar on duet.

    The other option is change the board, but i should not have to do that.

    Have you used fans on the Duex before?

    What position do you have the fan voltage select jumper set to?

    I think ; M563 P0 D0 H1 F3 should work.
