Here is my crafting set-up. I plan to have a lot of Interfaces and Molecular Assemblers and also lots of processors...but I ran into another problem. None of the Import Buses are working. I've tried breaking everything down and that didn't work. The Quantum Ring is linked to my main Base and all crafting is done here. Fixed a problem and seeing if it all works. Had to detach subsystem from the Quantum Ring and rebuild Processor Assembly.
EDIT: Found the problem with the Non-Functional Import buses, it's the Quantum Ring. For some reason, when I make the two of them and connect them to the controllers, they turn off the buses. Tested it by removing them and placing a chest and storage bus with the items I need to craft. The buses worked and when I replaced the Quantum Rings, they stopped working.
