Connecting to a CNC machine, pros and cons of USB vs PP vs Ethernet etc.

Well I'm not going any deeper because you clearly don't get that Mach3 isn't real time so WTF does it matter.!!

I just quoted you on those Ethernet controls (like the CSlab) being 'buffered not realtime' because it's a great way of putting it, so, yes, I definitely get that part!

Oh and who says you can't undercut with 3 Axis.!!

I included the word 'arbitrary' to try to rule out the use of specialised tooling as used in that video (and, of course, to rule out things like tilting tables, vices etc.,)

However, it works just as well as the example: you jumped in with a correction because you saw something you felt to be misleading.

This is exactly the same thing as I've done - difference is that I've been called a fair few names plus suggestions of physical violence for my trouble.
