Yes the EMC does support probing.  There is a working probe routine under
the tkemc scripts menu.  If you are using steppers, you can access the
probe pins on the parallel port.  They are settable in the script.

The probing routines look for a switch in the value of a input pin and stop
the probe axis when that pin closes.  It also reports the real-time
position when the switch closure happened.

But this may not answer your question because one kind of real digitizing
requires the repeated probing of many points on some kind of user definable
grid.  Such a script could be written.  I've got a real crude one here.

So that said, I'm curious to know what your suggestions are?  Several
others on this list have expressed interest also.
