Here's the G-Code he used for that photo. You can see he's doing 1mm passes
turning the rotary table 3 turns. His mechanics are such that it cuts air
at the start and at the end of the spiral.
The question I asked him which relates back to my own system is what does
F300 indicate? X at 300 mm/min or the rotary table at 300 degrees per
minute. Or is it both? Ie. F300 for the rotary axis is 300 degrees per
minute while the X axis is 300 mm/min.

I see now. That looks like a scroll for a 3 jawed chuck, a much tighter
twist than I had envisioned as I was imagining a turbocharger wheel in
my mind. For this, Z feed here is only for DOC. And it looks as if you
did well! Congratulations are in order!
What mill is that? The post cover looks a lot like my go704.
I have no idea. The fellow is in Europe somewhere. I think Spain. And
yes. It's a scroll for a chuck. Past that I know nothing.
