+ * to set spindle speed, spindle direction, and laser power.
+ *
+ * SuperPid is a router/spindle speed controller used in the CNC milling community.
+ * Marlin can be used to turn the spindle on and off. It can also be used to set
+ * the spindle speed from 5,000 to 30,000 RPM.
+ *
+ * You'll need to select a pin for the ON/OFF function and optionally choose a 0-5V
+ * hardware PWM pin for the speed control and a pin for the rotation direction.
+ *
+ * See http://marlinfw.org/docs/configuration/laser_spindle.html for more config details.
