RIGHT ON STEVE!! HAPPY NEW YEAR!!
     I have run a 2 axis Proto Track control for drilling
like you said and it worked GREAT. Also, if you use the
machine to cut contours, use the water line sectioning
for the contours and it will work much better as you only
mover the vertical a little for a lot of moves in the X & Y.
