I flashed Marlin 1.1 on my UMO+ with Dual-Head.
configured all - works.
BUT: The Extruder Auto-Fan doesn't switch on.
I tryed to change the Pin to 255 (like in the marlin 1 before) -> failre during compile.
Now i figured out, that 255 is not the real pin.
If i try pin 7, i get failure too:
#if E0_AUTO_FAN_PIN == FAN_PIN #error "You cannot set E0_AUTO_FAN_PIN equal to FAN_PIN."
How can i solve this?
I think pin7 is even the wrong - this is the 24V fan, isnt it?
