Hi there!
Is there anyone that have tried and have experiance of both motor fitted encoders and ball screw fitted encoders on a Ajax system? I now have linear scales on my milling machine and an Anilam controller, but replacing it.

1. How much backlash and belt tension error are the belt drive producing and could it be compensated at all?

2. The screw pitch error could be compensated, but how about the pitch error while temperature changes on the ball screw?

Screw mounted encoders seems that at least one error source are eliminated, but one still exists. Motor mounted have two error sources, the questions is if it have practical influence of the workpiece??
What experiances have you got, my fiends?

Best regards from Sweden,
