Ron, not about YOU at all.

This is a group for folks new to CNC. Although you may have done it
that way to serve some purpose, IMO many here would not know that.

And seeing as how the machine is being presented as an optimum and
advanced type; it seems likely to me that someone new just might
want to copy what they see toolpath-wise. (Why? Cuz that's the way
the experts do it; I saw it on a video... A machinist corollary to
the cut off both ends of the turkey thanksgiving story.)

So I mentioned the serpentine and the why; then added the use-
fastest-axis-for-longest-move at the end.

You might think these things are obvious; but many years of
instructing folks new to CNC has shown me that they are not.
