Re: [CAD_CAM_EDM_DRO] Laser Distance Measure

The NCDT device doesn't look very accurate if I was going to a single device
the Optodyne laser position sensor that outputs quadrature and a mirror
would be in the same price range with 6 place accuracy. These sensors are
used for very precision machines and can be used in a portable basis just
with a 5 volt supply.
