+// 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
+
+// If your machine has laser focuser, set this to true and it will use Z axis for focus or disable it.
+#define LASER_HAS_FOCUS false
+
+
+/// The following define to use the new HakanBasted laser_pulse method to fire laser. It should be more efficient, but it's less tested.
+// Thanks for it to HakanBastedt that has implemented it for Marlin at https://github.com/HakanBastedt/Marlin
+// Uncomment to enable it *USE AT YOUR OWN RISK*, it should work but it's *NOT WELL TESTED YET*
+//#define LASER_PULSE_METHOD
+
+//// In the case that the laserdriver need at least a certain level "LASER_REMAP_INTENSITY"
+// to give anything, the intensity can be remapped to start at "LASER_REMAP_INTENSITY"
+// At least some CO2-drivers need it, not sure about laserdiode drivers.
+#define LASER_REMAP_INTENSITY 7
+
+
+//// 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
