Grex G100 + Linear Encoders?

[rpseguin]

Anybody out there using linear encoders with Geckodrive Grex G100?

I'm thinking about using a Renishaw 0.5 micron resolution scale tape and readheads for a machine I'm building.

Looking for feedback from those who have done it.
I already know there can be backlash issues...

What was your outcome?

THANKS !!

We do not recommend linear encoders, because of backlash issues. Unless you are using a toothed-belt and pulley, which works very well because of its minimization of backlash but does not work in milling machines due to its limitations, a linear encoder is not ever recommended. The only way you could do it is with a dual-loop system, but we do not support those so I suppose that is a moot point.
