Not at all.
Just know what your limitations are
ahead of time and what to expext afterwards.

Not necessarily.
It's really up to you.

*PERSONALLY*, if you've got enough travel in your quill, I wouldn't bother.

The thing is, there *are* some times that moving a knee is very handy,
like clearing odd shaped workpieces, fixturing, and hold-downs.
It would be very easy to call the knee a fourth axis and integrate a clamping
signal much like a spindle brake.

I don't see why EMC couldn't handle it... <grins>
