G10 is almost always the correct in to use for this.

Hi Gene,
I gave up on centering my cheap probe because it really isn't necessary. I
don't need the probe to be concentric with the spindle if I know the
offset. My procedure is:
- center a hole under the spindle. For a hole, I've created a fixture
with a magnet holding a bearing. To center
screen jog keys
work on my AXIS implementation.
I'll continue this discussion on that forum.
