I'm thinking of digitizing my necks. I've got a really efficient tool path pattern for the shaft, but the blends need some help. I've got a stylus made that's .015" over the size of a 1" ball mill so that I can take the raw point data and not have to deal with offsets.

Ideally, I'd like to control the X,Y movement of the digitizing grid so that the digitizing path follows the existing shaft tool paths. In otherwords, I'd like to take the existing shaft tool paths and add contoured ends to blend into the headstock and body.

I could probably write some code and do this semi-manually, but I'd need help to modify existing digitizing code.

Any thoughts?

It's a lot easier to take contours by slicing a neck up (literally or figuratively) and make a good model from them to get where you're going than to grab points. The only exception being if you had something fully-automatable like a Renishaw probe.

I've got a laser scanner and could probe stuff in the Fadal using a manual probe (wiggler), but I don't do either for necks. Data equivalent to a few contour curves, placed in space correctly, takes a LOT of points.
