pin PD12 used multiple times in config

Trying to set up two fans for the drivers, adding the following lines results in an error

pin PD12 used multiple times in config

pin PD12 used multiple times in config

:

On lines 137-145 of printer.cfg,

[controller_fan controller_fan_1]
pin:PD12

[controller_fan controller_fan_2]
pin:PD13

[controller_fan controller_fan_1]
pin:PD12

[controller_fan controller_fan_2]
pin:PD13

I don't know where PD12 is used previously.

Also, could I simplify this to

[controller_fan controller_fan_1] pin:PD12, PD13

[controller_fan controller_fan_1] pin:PD12, PD13

and should I tie the enable_pin to the steppers?

Solution

no, you already have one fan defined as a controller fan using the pin you want. Just add the other in your printer.cfg

[controller_fan controller_fan_2]
pin:PD13

[controller_fan controller_fan_2]
pin:PD13
