It's not XYZ but Theta,Theta,Z machine was created by Krish135
I have made this to drill PCB's with 4 sizes of holes without tool changer. It is not a X,Y,Z type of machine.
As you can see it is Theta,Theta,Z machine. With many inputs from so many forums I made it.
I want to add routing, But I am not successful. Will anybody help with the relevant methods.
I used Parallax Propeller, and Processsing software.

That's different!
I'd say you would need to write your own kinematics to map the cartesian XY coordinates to you "Theta,Theta".

Yes, the answer here would lie in kinematics.
An advantage would be that you could then program the G-code in XY space. (I imagine that currently you are pre-computing the angles?)
Whether tool change is part of kinematics is a decision to be made.
The maths will be (slightly) different, but the basics of writing a custom kinematics is here: linuxcnc.org/docs/2.8/html/motion/kinematics.html
