I have installed a RRD Fan Extender in my Robo 3d with dual extruders. I'm running a Ramps 1.4 on the latest marlin firmware.
By default the firmware enabled Pin 4 for D4 output for Fan control, which is good.
I have my primary extruder cooling fan set to be always on, but I'm looking to have the secondary extruder only have the fan enabled when the extruder is on.
I've been searching around but unable to find out how to define this pin.
I see a CONTROLLERFAN_PIN 10 // Pin used for the fan to cool controller, which I assume means to cool the ramps board.
I also see a FAN2_PIN on other board examples.
Does anyone know what pin to define to accomplish this?
