Connecting two board fans to the Octopus 1.1
Instead of wiring my two board fans in parallel and connecting them to PD12 I wanted to get the Octopus to trigger PD12 and PD13 in parallel.
So I connected the fans to PD12 and 13 and added the following lines at the end of the printer.cfg
[multi_pin fan_controller_board_pin]
pins: PD12, PD13
hoping this will replace the original definition of fan_controller_board_pin.
There is no error saving and restarting but the board only starts the fan on PD12.
What am I missing?
Thanks!

you need to also use the multi-pin you defined like this:

Thanks! I just don't understand how I should adapt you example of the part fan to the controller board fan.
Thanks man! I really appreciate your help!
Klipper is not happy with the multi_pin:fan_conroll... part.
I also tried
pin: fan_controller_board_fan
No error but only one fan runing...
I'll keep on trying
And will report back
Got it to work - sort of:
multi_pin fan_controller_board_pin]
pins: PD14,PD13
[controller_fan my_controller_fan]
pin: multi_pin:fan_controller_board_pin
But I could not use PD12 - klipper complained it was an alias to the original fan - yes, I got that and wanted to replace it. But what the Fred - I don't need THAT many fans right now 😀
replace PD12 with the alias name instead
you can also just add a second controller fan, they do start automaically anyway
[controller_fan controller_fan_2]
...
then you dont need that anoying multipinThanks!!
