Re: CNC macro rail

If ultimate precision is what your after, then with 500mm stroke and 85kg combination, you should think about stiffening that shaft as 16mm is quite small.  You will definitely have significant bending to the point where your linear renishaw encoder will have alignment issues.  I've used those encoder's in my workplace, and tbh, they are very sensitive to alignment issues, which mostlikely will be your worst problem if precision is your ultimate goal.
