wanted g code for flywheel

[propclock]

I have completed a 4 axis SHARP mill ( bridgeport size) with sanyo denki servo's
x and y, harmonic drive theta and gearbox z on knee.
with pmc corp at200 controller. I need some g code to check
out the power. So far I have engraved with free engraving tools and am verry happy with the engraving performance.
But I really have no real cad cam to generate g code for a 3 , 4 ,5 ,
6. 7, or 8, inch cool flywheel. I can do it if I really tried but was hoping someone
had something I could use. Anyone using pmc corps at 200 card and can
give me feedback would also be appreciated. If you would like my experience with sanyo denki motors with advanced motion controls drivers I might help you
with some problems. The closed loop switch and servo update rates.
