That looks like the Chinese made unite from SD ZIMA- uses the scales from
digital calipers which can be ordered in either horizontal or vertical
display or with the remote display. Wholesale Tool offers this system as
well. Problems with batteries in scales and poor cabling connections have
plagued these units as well as low resolution- the scales are highly
sensitive to liquids, so are not good on the tables where flood coolants are
used.
Mounting is pretty simple as the scales have a bracket on each end and they
can be cut with a high speed abrasive wheel. The unit I had experience with
used LCD display which was not bright.

Over a year ago I started hunting for a DRO system for my Mill/Drill! I
looked at everything offered for a system. What I found were 2 key
problems
system price was one and other DRO installation.

A Mill/Drill has no built in mounting points for DRO addition unlike many
knee mills. I quickly found that no DRO system seller had any support or
installation design for a Mill/Drill! Scale accuracy of a DRO system is
absolutely dependent on its mounting system. Most reasonably priced
system
matched purchase cost my mill/drill and the rest were much higher!

Problems aside I still wanted the major benefits of an instrument based
positioning system, repeatable accuracy and reduced layout time!
Frustration is a great motivator; I ended up hunting the world for a
solution. I eventually located scales that supplied needed quality and
repeatable accuracy. Also now have manufactured an easy to read and use
3-axis LCD display system.

I decided to form these components into a Kit! Put in the time needed to
engineer a rigid mounting system and write an easy to follow installation
guide. My secondary goal for a mounting system was too use existing
fastening points. Complete installation requires only 2 new fastening
points.

Over the past 4 months I have been selling system in limited numbers
primarily on EBay. User input has been very helpful for continued
development! Comments have been enthusiastic on both accuracy and value
of
this DRO system. Systems have been installed on machines from RF15 to
RF45
and clones. One major need did become apparent in testing many users
needed
brackets to be supplied. Those are now included with kit purchase along
with
1 year USA Warrantee and installation support. System cost is under
$400.00
and can be viewed on EBay Item #3857220019 or
