Well, your submitted base does need a second Component Factory in order to make use of the Complex Dongle in auto-crafting. (That was the main issue.) Dongles have to be in ascending order along hte conveyor (unless you want resources to travel around a loop repeatedly for funs). I demonstrated this here in my last vid.and that's with having multiple component factories in a loop.
(If you post your campaign base with problems somewhere else, I'll debug that for you.)
The bugs to be aware of are Filters and Refineries jamming up and skipping resources if you have them transferring from conveyor to another conveyor. (Filters miss 1 in 3, refineries 1 in 6.) If you have them input directly from, or to, a Silo you can get them to run without missing a beat.
So, for input refining I'd have a single Refinery attached directly to a 2x2 Silo that takes all inputs and a Filter that only outputs refined chunks. A simplification of what you already have. I'd send input components to a delivery canon. So maybe have the scrapper at the bottom input too. And for the sake of this submission, maybe scrap one or two deployed resource blocks.
Absolutely. I approve.a more vertical approach instead of a spread-out flat one.
