/**
 *  M3/M4/M5 - Spindle/Laser Control
 *
 *  If you want to control the speed of your spindle then you'll have
 *  have to sacrifce the Extruder and pull some signals off the Z stepper
 *  driver socket.
 *
 *  The following assumes:
 *   - the Z stepper driver socket is empty
 *   - the extruder driver socket has a driver board plugged into it
 *   - the Z stepper wires are attached the the extruder connector
 *
 *  If you want to keep the extruder AND don't have a LCD display then
 *  you can still control the power on/off and spindle direction.
 *
 *  Where to get spindle signals
