Hi all as title
I want to connect the extruder cooling fan to the second extruder outlet so that the fan will only turn on when it gets to a pre-set temperature.
Is this possible? if so what do I need to change in the firmware to make it work?
You can just go edit the Pins.h file for your board. You would take away the declaration for the 2nd extruder. And you would use that same pin number when you add a declaration for your fan.
