I'm surprised if an IDEX has a separate PWM part cooling fan for each extruder that I can't assign them to the individual mode for the single extruder. Both P0 and P1 are always controlled in the GCode.
In single extruder mode, I don't always want the part cooling fan of the inactive extruder to be activated. How can I adjust that if I want to accommodate all extruder modes in one profile? Or do I really have to create a separate profile for each mode?
