Locate the top assembly base plate (shown in image), (3) 1/4-20 button head screws, and (3) TSLOT nuts.

In this step and all other steps using the TSLOT nuts, the boss (ridge) on the nut should be facing away from the head of the button head screw.

All of the horizontal plates are laser engraved with XYZ tower indicators. You are going to be installing all of these main horizontal plates in the orientation that puts the XYZ text face up.

You will install the Z tower assembly first. To do so, flip is upside down and slide a TSLOT nut into the TSLOT as shown. Align the nut as shown.

Next install the top assembly base plate (ensure you get the Z tower position with the Z tower) by aligning the tabs and cutouts. Hold the panel down flush against the tower plates. Look through the hole for the 1/4-20 button head and ensure that the TSLOT nut is centered with the hole. If it is not use your hex driver to move it into position.

If you are having troubles getting the button head screws to engage the TSLOT nuts, first ensure that you have the nut aligned with the hole, second loosen the 1/4-20 button head screws slightly on the side plates.

Insert and tighten the 1/4-20 button head screw. You CAN fully tighten this screw.
