User outputs allow you to output digital (on/off) and analog (PWM) signals via gcode. The code is sychronized. This means the change on the output pin occurs after all prvious gcode in the buffer has completed.
The analog signal can be used to control RC Servos. Consider a 50Hz (typical) servo with pulse range of 1ms to 2ms. 50Hz has a period of 20ms, so 5% is 1ms and 10% is 2ms.
