Tim,
Just got around to doing this - did it exactly like you had on
your site; no luck. I'm using KellyCAM - and everything else is working
great but this won't do anything. Power was going to it and everything,
it just want engage the relay.
Any thoughts?

Also remember that many (most?) parallel ports don't have enough current
to
drive a relay (solid state or standard) directly. You may need to put in
a
transistor to do the trick and drive the relay from the transistor
output.
In have some info on this at http://www.ktmarketing.com/CNC.html then
pick
the 5th link from the top titled "Parallel Port Hookup to Controller".
It is
on the bottom of that page.
