Re: [CAD_CAM_EDM_DRO] are 3/4 shafts good for axis ?

Avoid unsupported round shafts if at all possible. They flex badly. Even
1" will flex a surprising amount.

Have you considered V groove bearings and rails? IM Service stock the
bearings and rails quite cheap

use wipers on the rails they work quite well.
