Nurbs machining

Hi
I am new to the list. Im happy to see the intrest and hear other
ideas.
I have never ran a machine that had NURBS g code commands but have cut
parabolic shapes before on regular CNC controls in a Macro format which you
can also create your own NURBS G code interperter. The macro can have the
varibles and increment rate to do the calculations. The great thing is it
removes human error in relaying alot of numbers and makes a compact program.
Do any of the home built controllers have Macro programming features?
