An Example "Main Network"
Many other setups reference a "Main Network". You might also ask how all these devices come together into a functional system. Here is an example:

A big cluster of pattern providers and assemblers give a lot of space for crafting, stonecutting, and smithing patterns. The checkerboard pattern allows providers to utilize multiple assemblers in parallel while keeping it compact. Groups of 8 make it impossible for channels to route incorrectly.
Some machines, with a pipe subnet to push their outputs into the providers.
Some terminals and assorted utility doodads. (you probably want just a crafting terminal, not a regular terminal and crafting terminal)
An array of crafting CPUs. A few with larger amounts of storage and a bit more with lower amounts of storage. You probably want to have more co-processors in an actual setup but that would be a bit large for this scene.
Your controller should be in the middle of your base, and probably a bit larger than this. A stick-shape is pretty good.
Various methods of doing storage, with drives or storage busses. Notice all in groups of 8.
