/**
* Laser:
* M3 - Laser ON/Power (Ramped power)
* M4 - Laser ON/Power (Continuous power)
*
* Spindle:
* M3 - Spindle ON (Clockwise)
* M4 - Spindle ON (Counter-clockwise)
*
* Parameters:
* S<power> - Set power. S0 will turn the spindle/laser off, except in relative mode.
* O<ocr> - Set power and OCR (oscillator count register)
*
* If no PWM pin is defined then M3/M4 just turns it on.
*
* At least 12.8KHz (50Hz * 256) is needed for Spindle PWM.
* Hardware PWM is required on AVR. ISRs are too slow.
*
* NOTE: WGM for timers 3, 4, and 5 must be either Mode 1 or Mode 5.
* No other settings give a PWM signal that goes from 0 to 5 volts.
*
* The system automatically sets WGM to Mode 1, so no special
* initialization is needed.
*
* WGM bits for timer 2 are automatically set by the system to
* Mode 1. This produces an acceptable 0 to 5 volt signal.
* No special initialization is needed.
*
* NOTE: A minimum PWM frequency of 50 Hz is needed. All prescaler
* factors for timers 2, 3, 4, and 5 are acceptable.
*
* SPINDLE_LASER_ENA_PIN needs an external pullup or it may power on
* the spindle/laser during power-up or when connecting to the host
* (usually goes through a reset which sets all I/O pins to tri-state)
*
* PWM duty cycle goes from 0 (off) to 255 (always on).
