Grooving with Pathpilot

Will somebody please explain to me how to do a single plunge groove with conversational?
.031R round nose tool, tracking point 2. 0.750diam to 0.312diam. Start of groove is 0.188, end 0.250. Z zero is the end of the part.
I cannot make heads or tails of it, and NX is about screwed up as a soup sandwich when it comes to grooving.

Thanks.

I got it. Finish DOC 0.0

Figured out NX too, had to turn off minimum cut area to be able to recognize small volume of stock.

Thanks for the update, I was just hoping on here to take a look at this.
