Second, in order to have the Y axis movement be in the forward direction during the home
move, you need to rotate the Y axis 180 degrees with respect to the rest of the manipulator.
To reverse the Y (bottom axis in the rotated configuration), locate and loosen the 4 set screws
that attach the Y to the X. These are on the sides of the X or middle axis in the stack. When
the set screws are loose, you can move the Y off the X, rotate it 180 degrees and reinsert its
mounting posts into the correct holes in the X (the holes with set screws). Finally, press the
two axes firmly together and retighten the setscrews. Now the Y-axis will move forward
during the home move and back during the work position move.
