Also I am doing range checking [min/max values] and would
appreciate advise on the following points, assuming you are using
small endmills for sign creation, etc.
(1) What are the min/max vertical feedrates and units that you
would ever use?
(2) What are the min/max horizontal feedrates and units you would
ever use?
(3) What is the min/max distance above the surface you would ever
use?
(4) What is the min/max plunge below the surface you would ever
use?

Let the user input them & save them in a default file for the user.
Next time use the defaults with an option to change & save them.
