I’m in the process of designing a small DIY CNC light duty engraver and I need some help with the best method of securing the ball screw shafts. I know there are blocks that can be used at each end of the screw but I’m interested in securing with a bearing in the frame. Is it simply a matter of machining the end of the screw and pressing a bearing into the frame or is there more to it than that? Is a bearing needed on both ends of the screw or is the motor secured to the shaft through a coupling adequate?
Any other suggestions or ideas would be greatly appreciated.
