Explanation of CNC G-Code
G00 : Rapid traverse.
G54 : Zero Offset no. 1.
G64 : Continuous-path mode.
G90 : Absolute dimensioning system.
G17 : X-Y plan selection.
G41 : Cutter radius compensation activation (left hand side movement)
G40 : Cutter radius compensation de-active
S : Spindle speed
F : Axis motion feed
M : Cutter rotation (3=clockwise, 4=anti-clockwise)
D : Tool offset no
