I'm having a little trouble using pin 12 as the fan pin on my sanguinololu 1.3a. It works OK with sprinter but with repetier I can only use the output as a digitial (on/off) and the PWM doesn't function. I can use pin4 successfully, but would prefer to use another in for heated bed and use pin 12 for fan. It looks like this is something to do with the timer interrupts. Any idea how to fix this?
