[title] Strapping the top
[* icon_caution] Once you have all of the cross member extrusions in place ''be very careful '' when moving the top assembly around.
[* red] Alignment and tightening the upper assemblytop is similar to the base. But sinceSince there is only one extrusion between corner brackets, you can tighten both the top and bottom screws at the same time during alignment.
[* red] Wrap the cord around the top assembly and pass it through the loop. Pull the cord tight and tie off to the cord itself, don't tie it off around the cross member like you did in ''Step 10''.

[* icon_note] The photo shows a simple overhand knot holding the cord tight.
[* red] Move the top assembly to the flattest smooth surface you can – a granite kitchen counter, smooth Formica™ counter or even a smooth table top work well. Just make sure it is clean (no crumbs!) and flat.
[* red] Push the cross members flat to the table and then tighten the six upper and six lower screws you can reach near the stepper motors. Then tighten the six screws inside the corner brackets.
[* red] Flip the assembly over and tighten the other six screws inside the corner brackets.
[* red] Make sure all twenty-four screws are tight. Lay the top assembly on a flat surface with the '''XYZ''' labels facing up and test to see if it rocks or tips. If so, you need to loosen ''all of the screws'' and ''repeat this step'' again! So best to work carefully and get it right the first time.
