- * M3 - Cutter ON (Clockwise)
- * M4 - Cutter ON (Counter-clockwise)
- *
- * S<power> - Set power. S0 turns it off.
- * O<ocr> - Set power and OCR
- *
- * 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).
