RE: 5 axis controller

[john s finnila <jsfinnila-at-juno.com>]

I am forging ahead on my 5-axis milling machine project.  I have some
additional 
questions.  Does the emc controller have soft limits to prevent to
prevent the machine 
from crashing into the mechanical travel limitations of the machine? 
Normally these
soft limits would be setable from the machine coordinate home position. 
This prevents
over travel of the ball screws in the advent of a part program error or
setup error.  One
control I know of even gives an error message that prevents starting a
part program 
if these soft limits are exceeded.  Some basic PC questions for this
control.  How fast
should the PC be?  How much ram is recommended?  How large should the
hard drive be?  Which emc files would I need to install for this system? 
What  would be the recommended linux files to install?  Your answers to
these questions would be greatly 
appreciated.  I am currently gathering all of the hardware for this
control retrofit  so that
is why I haven't gotten into the software very deep.  Your patience is
appreciated.
