FAN0 not working, but the rest work just fine



  • Hi all!

    I'm having problems using the first fan port on my Duet 2 Ethernet.

    Here is my config.g:

    ; Configuration file for Duet WiFi (firmware version 1.21)

    T0                                       ; Select first tool
    
    

    My config-override.g only has heating profiles.

    What am I missing? Is the board broken?

    My current workaround is to use FAN2 instead, and map it in the tool 0 definition;
    M563 P0 D0 H1 F2
    This works fine, but I'd rather connect 12V led rails on FAN2.
