DIgitizing a part with no probe

I posted this on CNCzone a while back with no avail so ill try it here

Back when I used to program CNC routers for my job we had a router that we could lay a cardboard template down, drive the machine manually and place the axis where we wanted and hit a button and create a point. The software that drive the machine (windows based if I remember right,this was 7ish years ago and it was old then though) would output a dxf which we could open in autocad and create curves off the point cloud.

Im looking to something similar with my router and Emc. Im currently using ubuntu vs 8.04 and I think EMC 2.3. I dont currently have anything special set up in my config file, I dont even have my limit switches wired in yet Im using the probotix stepper drivers and breakout board for my electronics.

Im not at a point where I want to create a probe sequnce or even really make a probe, I would be happy with manually jogging the machine with a fine point bit and pushing a button when I get where I want to be. Really I would be perfectly happy with EMC creating a text file with the coordinates I need. So jog to a point, click a button, Coordinate output. Anyone have any ideas, I need to do this tonight, so simple is great

THANK YOU!!

That is exactly the kind of info Im looking for. write now im jogging to a location, then writing down the coordinates by hand. Not exactly the best method. This could be useful for a ton of reasons. Ill post up when I make some progress.
