I am looking for advice on servos for my Sherline 5000 mill. I will be doing engraving and milling aluminum. What servos will give me a robust setup, with good feedrates...without missed steps?
Servo's usually don't miss steps they fault out "stop", stepper motors miss steps.
A complete servo solution may cost 50 percent more than a equivalent stepper solution.
See the attached links for some good information.

I would be happy to chat if you want more info.
