Firmware Setup for Fan Extension Board when you are already running 2 extruders and a heated bed.

I need help configuring the firmware to run 2 object fans. i already have all other outputs maxed out using 2 extruders and a heated bed.
so i got the fan extender board, but i can't figure out how to assign the correct pins in order to get this to work, can someone help.


  • Just assign the digital pin number where it is connected to the fans instead of ORIG_FAN_PIN.
  • Fixed this, i used the complier to sort this, but i now have another issue with i will post separately.
