* NPr2 support, multiextruder by NicolaP http://www.3dmakerlab.it/extruder-npr2.html
* Laserbeam support
* Laser for RAMPS buildlog based 3d laser cutter (like modified chinese K40) with both vectorial and raster support
compatible with inkscape plugin at https://github.com/TurnkeyTyranny/laser-gcode-exporter-inkscape-plugin
* Laser pheripherals (water cooling, air assisted lasering)
* Firmware test
* Support for a filament diameter sensor, which adjusts extrusion volume
* Support for a hall effect sensor for calucalte Wh. Example sensor ACS712 20A range Current Sensor Module. http://i.ebayimg.com/images/i/310506962976-0-1/s-l1000.jpg
// 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
//// Uncomment the following if the laser cutter is equipped with a peripheral relay board
//// to control power to an exhaust fan, water pump, laser power supply, etc.
//#define LASER_PERIPHERALS
//#define LASER_PERIPHERALS_TIMEOUT 30000 // Number of milliseconds to wait for status signal from peripheral control board
//// Uncomment the following line to enable cubic bezier curve movement with the G5 code
// #define G5_BEZIER
