Rotating Axis Controlled by a Ballscrew

I think that this is a perfectly valid approach, and as you have noted, it was used by Centroid.

The "right" way to do this is probably with a custom kinematics component. That way it is solved by mathematics.

Thank you Andy and thank you besriworld, I also feel this is a viable solution, Ofcourse what besriworld about the ballscrew taking radial load is true but we can fix that at a lower cost than some of the other solutions available. I will look into that aswell ass the solutions suggested by besriworld. Thank you all once again
