Probe for center of hole

Chris Radek has agreed to "re share" this neat sub to find the center of a hole and also list it's dimensions.

It can be found at...

It also looked like the perfect candidate to be added to ngcgui.

Here I have taken Chris Radek's hole center finding routine and modified it for ngcgui.

In the attached file the:
The g0 moves have been changed to g1 for the less adventurous.
Added correction fields for center location of hole.
Added correction field for x and y diameter.


Simply enter the proper information in the fields, jog the probe to a position inside the hole and go.
