Dave,
I have a basic understanding of the coordinate systems and
where they are stored. Homing was not the issue. Homing was working
fine. This pas weekend I had a little time to play, and monkeyed
around with the ini file to coordinate the movement of the machine to
the movement on the AXIS display. That seems to have cleared the
issue up completely, and touching off is working correctly now. The
only reason I set the "touch off" position from the homed position
was to see if "Touch Off" was actually working, or if I needed to
delve a little deeper. Touching off from home was not the desired
outcome, it was just a test. The machine, when touch off wasn't
working, did show the nice little "center" circles on each axis
indicating that all three axes had been homed.
