With an Allen wrench remove the lubricant set screw on your Y axis ball screw bearing, as seen in the first image and indicated by the red arrow
Next push your lubricant into the hole you just removed the set screw from
Squeeze the lubricant until you see lubricant come out of the top of the bearing between the white gasket and the ball screw, as seen in the second image
Next, manually turn the ball screw so that the Build Platform moves away from the limit switch, about 2 inches, then move it back to where you started
Squeeze more lubricant into the bearing, and manually move the bearing away from the limit switch, about 2 inches, then move it back to where you started
Put the set screw back into the hole where you removed it from and turn it so that it is set inside of the hole about one half turn from being flush with the hole opening
This step is exactly the same for the X axis ball screw bearing, repeat this step for the X axis, refer to the second image for the set screw location
