FAN0 not working, but the rest work just fine

[skaramicke]

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)

M501

; Miscellaneous
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.
