Erik,
While not exactly what you are looking for, you can use C snippets to

If you want an adjustable knob as an input to LinuxCNC then an encoder
is easier.

It is the same there. (Or it can be).

ABC are end-effector angles

G-code *is* how you specify your Cartesian motion. Kinematics converts that to
motions of each joint or axis.
