Hi Terry,
Ah... this was a good idea. I didn't think of changing the rotation axis to Z. Now I see the toolpath more nicely. And for some reason I am seeing it twisted in the Z instead of getting continuously lower. This is probably why the part gets twisted too.
I am using my A axis in revolution mode, as stated in the Gcode heading, not in degrees mode, so 1 in the A DRO means one revolution of the axis. This is why you think it's not rotating all the way around.
