2.Install the GCode GUI Application. (Base on Adobe AIR)
3.Open the GCode GUI
4.Choose and Connect the Arduino Serial Port.

Linear interpolation: G1 X-100.5 Y90.4 Z1 (move 100.5 opposite on X-axis,move 90.4 on Y-axis and the brush will be down)
Circular interpolation:G2 I10 Z1 (it will be draw a circle that radius is 10)
Switch to absolute coordinates:G90
Switch to relative coordinates:G91
The GCode “Z” will control the brush,down for “Z1”,up for “Z0”.
