Maybe I should describe how I set up my tools on simple workpieces.
I lower the tool ontil it is almost touching the work. I then slip a piece
of paper that I know is .005" thick under the tool, and jog down until
the paper is pinched. I then right click on the Z axis and type .005
and hit the enter key. For X and Y, I use an edgefinder and jog over
until the edgefinder deflects to the side, then I stop the spindle (F9).
I right click on the axis, enter either .1 (the radius of the edgefinder)
or -.1, depending on which side of the part I'm on. Then, hit enter.

If I'm doing something that requires changing tools several times, I can
put the offsets for the different tool lengths in the tool table, and set up
the program to select the right tool offset with G43 H(tool #).
