Controller fan on Octopus Pro 446, config . Help please

Hi all To increase print speed I have connected two fans to the OctoPro board. I borrowed this code : Controller fan control [multi_pin controller_fan_pins] pins: PD12, PD13 pins: PD12, PD13 [controller_fan control_fan] Controller fan - FAN2 & FAN3 pin: multi_pin: controller_fan_pins max_power: 1.0 kick_start_time: 0.5 stepper: extruder But I get this error : Klipper reports: ERROR pin PD12 is an alias for fan_controller_board_pin Once the underlying issue is corrected, use the "RESTART" command to reload the config and restart the host software. Printer is halted I am clearly messing with something that could be solved much simpler.... Thanks in advance Thor

If you want a working example of dual fan for print cooling you can look at my config https://github.com/jscancella/myKlipperFiles/blob/main/vcore3-printer.cfg

So it should be
[multi_pin controller_fan_pins]
pins: fan_controller_board_pin, PD13
[multi_pin controller_fan_pins]
pins: fan_controller_board_pin, PD13

like @blacksmithforlife the multi_pin sections needs to be at the top of the file see: https://discord.com/channels/582187371529764864/843098069200666634/998705565679235132
