Hey there i build the x y plotter and with mdraw it works perfectly fine and it really is an awesome product.
But when i load the GCodeParser ino into the Board it seems like the plotter doesnt know where to end. Ill post the code which i use. Maybe i have a wrong setup/GcodeParser im using Plotter v2 with an orion Board.
So when i load the gcodeparser and i want to control it via GRemote it goes into the step init but he just drives against one of the axis without stopping.
Code
`#include <Servo.h>
// define the parameters of our machine.
float X_STEPS_PER_INCH = 48;
float X_STEPS_PER_MM = 40;
int X_MOTOR_STEPS = 100;
float Y_STEPS_PER_INCH = 48;
float Y_STEPS_PER_MM = 40;
int Y_MOTOR_STEPS = 100;
float Z_STEPS_PER_INCH = 48;
float Z_STEPS_PER_MM = 40;
int Z_MOTOR_STEPS = 100;
//our maximum feedrates

long FAST_Z_FEEDRATE = 2000;

// Set to one if sensor outputs inverting (ie: 1 means open, 0 means closed)
// RepRap opto endstops are not inverting.
int SENSORS_INVERTING = 1;
// How many temperature samples to take. each sample takes about 100 usecs.

Maybe you could post your code 
Thanks in advance!
