* Support for a filament diameter sensor
* Also allows adjustment of diameter at print time (vs at slicing)
* Single extruder only at this point (extruder 0)
*
* Motherboards
* 34 - RAMPS1.4 - uses Analog input 5 on the AUX2 connector
* 81 - Printrboard - Uses Analog input 2 on the Aux 2 connector
* 301 - Rambo - uses Analog input 3
* Note may require analog pins to be defined for different motherboards
