Install bed corner screws as shown. Note the orientation, there is a non-symmetrical center hole, and two "slots" on the edge. Make sure to align as picture shows. Install bed corners using a M3 x 12 SHCS, M3 washer and a bed spring (~9.5mm). Set the end of the bolt flush with the bottom of the plate for now. Install bed finger as shown using a M3 x 12 SHCS and M3 washer. Repeat in all 4 corners.
Set the table in the fixture. If not using the fixture, this can be done by setting the aluminum plate on its edge. Using 4 M3 x 12 SHCS and 4 M3 washers, attach the belt mount to the table as shown. Note orientation in picture, if it does not match, you will need to re-do the previous steps.
