Re: digitizer arm, w/ encoder?

Alan, list,

The issue to solve with this probe, IMO, is how to allow 3 direction
sensing while accomodating overtravel. This way you can treat it like
a home switch. Probe 'til state change.(quickly) then retract and
probe for position (more slowly). Just some thoughts.

Nice Idea!
