how can make fan 2 be a fan tool instead of fan 0 in duet 2 wifi



  • hi how can make fan 2 be a fan tool instead of fan 0 that does not work for me was probably short and the fuse burned I replaced another fuse ifind fuse 15 and now fan 2 and 1 work, and fan 0 does not work for me anymore, I tested it and tried to run fan 0 but it does not work itry M106 P0 S0 I0 H-1 not work, I connected to fan 2 and it works for me and I can control At cooling speed, the problem is that it is not controlled from the slicer how do I make it a fan tool thanks to the helpers

    You would bind fan 2 to your tool command.

    https://duet3d.dozuki.com/Wiki/Gcode#Section_M563_Define_or_remove_a_tool

    M563 F2



  • @Phaedrux Thanks i reading It confused me A little.
    How do you write this?
    Just add to fan line like that.

    M563 P0 F2?
    or M563 f2?
    Maybe my 0 fan needs resetting that's why he doesn't work after a the fuse Destroyed
    Isee some gcode Interesting
    M562: Reset temperature fault
    There's one for the fan? M562 f0?

    Post your current config.g.

    You will have an existing M563 in there to define the tool. It tells which heater to use, which extruder drive, and which fans to use.



  • @Phaedrux Thanks this is my config
    ; Tools
    M563 P0 S"hotend" D0 H1 F0 ; define tool 0
    G10 P0 X0 Y0 Z0 ; set tool 0 axis offsets
    G10 P0 R0 S0 ; set initial tool 0 active and standby temperatures to 0C

    Ineed to change it to D0 H1 F2?



  • @Roei3d no.

    Can you post your whole config as theres more to set than just that

    @Roei3d What firmware version are you using? Send M115 and post reply.

    For RRF2, you use the 'A' parameter in M106 to define which logical pin the fan is connected to. Logical pin numbers for fans are Fan0=20, Fan1=21, Fan2=22 (see https://duet3d.dozuki.com/Wiki/Using_servos_and_controlling_unused_IO_pins#Section_Logical_pin_numbers)
    So this will create Fan0 using Fan2 output:

    M106 P0 A22 S0 I0 H-1
    M106 P1 S0 I0 H45
    

    In RRF3, you define the fan0 on the fan2 pin with M950 first:

    M950 F0 C"fan2" Q500                           ; create fan 0 on pin fan2 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 T45                              ; set fan 1 value. Thermostatic control is turned on
    

    You don't need to bind any fan to your tool (if you only have one tool) as fan 1 is thermostatically controlled anyway. Fan0 doesn't have to be bound to the the tool either; it just controlled from the slicer with M106 S[0-255] commands. So tool definition can just be:

     M563 P0 S"hotend" D0 H1 ; define tool 0

  • @droftarts thnks for the help this do the trick A22 change fan2 to fan 0 thanks',

    And another question fan0 has a different mosfet from fan 1-2 ? Could it be that FAN0's mosfet has burned out and the other fan 2 fan1 connections have a different mosfet?
