Jeez! It really can't be this difficult!!!

While in CAM for turning, where is the origin typically located? The base of the stock(in the chuck) or the right end (toward the tail stock)?
Looking at the face of my chuck it turns counter clock, the tool holder is left of center . Chuck is on my left and tail stock is to my right.

Generally somewhere convenient. This could be a reference face in soft jaws for a second operation, for example.

However, in 90% of the work I do Z = 0 is the tailstock-end of the workpiece, and I face-off at zero as a first step.

And I'm the same the tailstock end of the material is Z0 and if a face off is done then I elect to set Z0 to the new face in ngcgui.
