The ball screw and linear guide were very dirty and covered with metal chips. The ballscrew has a few flaws, most notably missing a part on the underside that clicks into place when the axis reaches the end of its travel. It seems that such products may or may not be very successful, but on the other hand, there is no noticeable backlash or play when the bearing is in a spot without defects.
