The printer I'm compiling Marlin for has two sofware controlled fans. One is on the extruder, and I have it set as E0_AUTO_FAN_PIN.
The other is a part cooling fan, and I'd like it to come on whenever the slicer has set it to (like, I'm printing in PLA).
I have it defined as FAN_PIN.
However, the fan pin never comes on, no matter how what commands I issue (manually testing). The auto fan does come on when the extruder temp is > 50 degrees, and if I swap pin definitions, the part fan comes on, so I've got my pin definitions "right."
What am I missing to have the extruder fan automatically come on and the part fan controlled by the M106 command? Since M106 controlled the extruder cooling fan before I set it to auto, I would expect to be able to do M106 P1 S255 and have the part cooling fan come on, but I must have something misconfigured.
