Geeetech I3 Aluminium with Sanguinololu 1.3 + 2004 LCD + PWM Fan

I've made the A0/A1 mod from vad7 (http://www.thingiverse.com/thing:790758), but used A1 pin to control a cooling fan. A mosfet drives the fan with 12v.

I've used marlin 1.1.0RC7, but the customization will work with any marlin version I think. Just uncomment define line for FAN_SOFT_PWM in configuration.h and add the mod section in (last 4 lines) in pins_SANGUINOLOLU_12.h.

Testing the fan with this simple but very efective shourd http://www.thingiverse.com/thing:1684483
