As the SG20U Bearings roll across the rod there should
be a small amount of
preload
(i.e., they should securely
engage the rail and roll firmly). Check the upper bearings
to ensure that they are snug up against the rail. The
bearing should move along the rail when rotated by
hand.
If any of the bearings rotate without engaging the rail:
•
Remove both of the Y rods
•
Loosen the 2 nuts on the slotted holes on each side and slide the SG20U bearings upward
•
Snug the SG20U bearing nuts
•
Repeat 1 thru 4.
Place the remaining Y Rail Stops on the Gantry Side and secure
each with M4 x 25 screws and nuts. Please note the orientation
(the Rail Stop must cover the ends of the rails, keeping them in
place).
