Tony,

I'm not sure how this CONFIRMS anything??? It may be true that Taig
makes some MaxNC parts... Geographically, they are neighbors. Also
direct competitors...

The MaxNC 'digitiser' is a 3D single pole switch, nothing more. The
fact that it will fit an appropriate sized collet does nothing (that
I can see) to determine who manufactured the collet/spindle.

The way the physical construction of the digitiser was explained to
me was: A three 'pole' tripod with sharp tips which rest on
electrical contacts (3). Extending downward from the tripod top is
the probe tip. This means that a 'push' against the probe in any
direction will cause at least ONE of the contacts to be 'broken'.
Figure they must be wired in series, and are normally closed.

The SOFTWARE for the MaxNC digitiser is what will determine whether it
(the digitiser) will work in/with other machines...

Hope this helps.

P.S. The more expensive digitiser probes have strain gauges to sense
contact, and use replaceable (usually sapphire) tips. They are still
really just a 3d switch.
