Instructions For Assembling The Assemblies

So I just finished assembling the lower level assemblies (sides, Z Assembly, Center Assembly), and I’m ready for the next step of putting it altogether on my table.

The problem is, I can’t find those instructions. Am I missing something? I need to know how to route the belts, connect the x-axis tubes, connect the microcontroller, etc. Given all the details on the sub-assemblies, I’m hoping I’m not supposed to figure out the rest myself. Any advice guys?

This might help.
