Guys: I guess I am confused. I am trying to visualize a situation
where I would want to continue on with a program that has just driven
my table into the limit switches. At that point I think I would like
to take a deep breath, move my table back to home then check the code
that caused the problem. I understand the issue that once you lose
your place with an open loop system you are pretty much SOL on
getting things back to absolute 0,0,0. I always try to set my
material up so I have a known reference point by using an edge feeler
or conversly setting my machine to some 0,0 point and moving the
material to be back at zero using the offset method.

Like I said, I'm confused so help me out.
