+//
+// Laser control is used by the Muve1 3D printer and the Buildlog.net laser cutter
+//
+
+//// The following define selects how to control the laser.  Please choose the one that matches your setup.
+// 1 = Single pin control - LOW when off, HIGH when on, PWM to adjust intensity
+// 2 = Two pin control - A firing pin for which LOW = off, HIGH = on, and a seperate intensity pin which carries a constant PWM signal and adjusts duty cycle to control intensity
+// mUVe, buildlog.net and K40 chinese machines uses 2, AMRI ablative uses 1, AMRI SLS uses 2
+#define LASER_CONTROL 2
+
+// Uncomment the following if your laser firing pin (not the PWM pin) for two pin control requires a HIGH signal to fire rather than a low (eg Red Sail M300 RS 3040)
+/// #define HIGH_TO_FIRE
+
+// Uncomment the following to enable the use of the PWM (the one for the extruder 0) to drive a peltier cell or any PWM driven cooler for the laser
+#define LASER_WATER_COOLING
+#define LASER_WATER_MAXTEMP 25
+
+
+//// The following defines select which G codes tell the laser to fire.  It's OK to uncomment more than one.
+#define LASER_FIRE_G1 10 // fire the laser on a G1 move, extinguish when the move ends
+#define LASER_FIRE_SPINDLE 11 // fire the laser on M3, extinguish on M5
+#define LASER_FIRE_E 12 // fire the laser when the E axis moves
+
+//// Raster mode enables the laser to etch bitmap data at high speeds.  Increases command buffer size substantially.
+#define LASER_RASTER
+#define LASER_MAX_RASTER_LINE 68 // maximum number of base64 encoded pixels per raster gcode command
+#define LASER_RASTER_ASPECT_RATIO 1 // pixels aren't square on most displays, 1.33 == 4:3 aspect ratio. 
+#define LASER_RASTER_MM_PER_PULSE 0.2 //Can be overridden by providing an R value in M649 command : M649 S17 B2 D0 R0.1 F4000

+//// to control power to an exhaust fan, water pump, laser power supply, etc.
