Extruder fan controled by 2nd extruder output

Post by Suggy »

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?
