You don't have to house the VFD in a separate cabinet. You DO have to employ good practices. Very well stated Tom.

"good quality" and " China" dont belong in the same sentence. :mrgreen: Are they locked on the shafts with keyways or simply a set screw? Did you use Loctite on all the couplings where they meet the ball screw and motor shaft? If your measured backlash is only .0005 then I would ...
