so @rotarySMP you are saying that it should be better to implement new types of linear scales rather than put encoders on servo motors?

Position feedback from linear encoders negates most errors in the drive train, and should provide greater accuracy. As noted in the other thread, whether your drive train is stiff enough to only work with linear encoders will depend on your machine. If you ways a worn, the ball screw has back lash etc, you probably cant tune the feed back loop solely on linear encoder feedback.
