The Chinese ballscrews are rolled and not therefore not as accurate as ground,
or so I have read. However as I'm going to be using servos and linear scales,
I can't see this being a problem.
Any thoughts on this ?
Thanks Wallace.

It is arguable how much accuracy you actually need. What is the
tolerance on 12 distances on the parts you make?

Thanks for the replies.
Based on your comments, I am backing away from these for the time being.
Your comments led me to realize this is beyond my focus at this time. While
I certainly could attack this project, family, travel and home renovations
are trumping my efforts at this time.

If anyone is interested in chasing them, search Reading PA craigslist and
Mitutoyo and they will pop up. This is the second relisting (that I am
aware of) by the seller so its not like they are flying off the shelf.

I may pick up a set of linear scales which were part of a DRO for a milling
machine.
The DRO box was fried but the scales are reportedly still working. If I get
these scales, will I be able to hook them up using one of the available
boards (mesa or pico)? I have a 13.5X40 lathe I am considering

Thanks for the quick reply Glenn and Kirk,
The scales are quadrature output - Mitutoyo brand.
I recall the list discussion on the difficulty of using the linear scales
sometime last year or perhaps earlier. These are available close to me for
a decent price so I thought this might be a way to
