Editing and creating new G commands in gcode

[Andey the Great 0]

In gcode a line may look like : G10 X10 Y10 Z10

So the G has a bunch of specific functions such as linear or circular movement. However you can not edit this code. We are not using a traditional gantry x,y,z machine so we need to redefine the G01 or G03 commands for example or make our own.

So does anyone know the code behind the G01, G02, G03 commands?

We have 8 axis moving our head around instead of the usual cnc 3 axis. We used the kinematics feature of our Trio MC508 and it works but that controller costs close to $4000 and if we could solve this problem we could use our Dynomotion KFLOP which is under $1000 (kinematics can only do 6 axis). We can make it work by making each point very close but we get 400,000 lines of gcode for a simple 100mmx100mm cube so that is not good.
