basic fan control issue



  • I have two 5015 part cooling fans for my single hot end. I have them attached to F0 and F1. My understanding is that I should have the following in my config.g

    ;Fans
    M106 P0 S0 I0 F500 H-1
    M106 P1 S0 I0 F500 H-1

    ;Tool
    M563 P0 D0 H1 F0:1

    When I do this, my visible fans in DWC start a Fan2 and beyond, never showing Fan 0 or Fan 1....and Tool Fan is not there either.

    In one of my other printers (using a Maestro) I can see the following:

    When I adjust either of these up or down, my part cooling fan turns on and off, as desired.

    On my Wifi, with the same Gcode for fans and tools I get nothing:

    I can't pull any more hair out....



  • which firmware version are both running?



  • Definitely something wrong. Found a previous working SD card back up and the Fans and Tools sections were very vanilla:

    ;Fans
    M106 P0 S0 I0 F500 H-1 ; set fan 0 value, PWM signal inversion and frequency. Thermostatic control is turned off
    M106 P1 S1 I0 F500 H1 T45 ; set fan 1 value, PWM signal inversion and frequency. Thermostatic control is turned on
    M106 P2 S1 I0 F500 H1:0 T45 ; set fan 2 value, PWM signal inversion and frequency. Thermostatic control is turned on

    ; Tools
    M563 P0 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

    Fan 0 and Tool fan are somehow disabled.

    With the same gcode script for Fans and Tools on my other printer, I can see Tool fan and Fan 0. Same script.

    Could my DWC get corrupt?

    Both running 2.05



  • do a M98 P"config.g" and see if your config has problems



  • Well. My DWC was old. I just uploaded the latest release. Fan 0 showed up.

    So I update my config.g with

    ;Fans
    M106 P0 S0 I0 F500 H-1 ; set fan 0 value, PWM signal inversion and frequency. Thermostatic control is turned off
    M106 P1 S0 I0 F500 H-1 ; set fan 0 value, PWM signal inversion and frequency. Thermostatic control is turned off
    M106 P2 S1 I0 F500 H1:0 T45 ; set fan 2 value, PWM signal inversion and frequency. Thermostatic control is turned on

    ; Tools
    M563 P0 D0 H1 F0:1 ; 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

    And all of a sudden, both Fan 0 and Fan 1 showed up. Still no tool fan, but at least I have what I need.



  • @Veti

    Ran. From Console.

    M98 P"config.g"
    HTTP is enabled on port 80
    FTP is disabled
    TELNET is disabled



  • maybe its time to update to 3.1.1 for you.



  • In the new year. Too much printing to do before Christmas and I don't want to miss a 0 or a 1 somewhere in the conversion and slow my printing schedule down.
