Been a while since someone posted on this thread, not sure if my post is worthy. But I need to know if what I was trying to do isn't possible after spending many hours on it. Frustration, man.
It's Conveyor/Sorter related. I simply wanted to make my base Storage-Centered, with a Storage room having 'modular' storage for all item types (Large Ore Container, Large Ingot Container, etc).
I wanted to make it so every thing would be drained from the Refineries/Assemblers/Etc into such containers, and that I could retrieve or move items around properly (i.e. I can manually move ingots to assemblers, but not ore. And I can retrieve any type of item from my main storage from anywhere).
Even though I used Sorters with Whitelisting/Blacklisting left and right, and even though I played a good amount of Factorio and Minecraft with tech mods, I still couldn't get it to work without the usual infinite feedback loops or Sorters magically drawing Blacklisted items from inacessible containers.
It made me realize that really, the game wants bases to have an "in-line" or "serial" conveyor design (i.e. Input [Docks/Etc] > Ore Buffer > Refinery > Ingot Buffer > Assemblers > Component Storage), so such generalized designs like mine (Main Storage > Everything Else) doesn't seem pratical or doable to me.
Since I can't get over the possibility that I might be derping, I must ask..did anyone ever do something like this? It seems simple and intuitive yet I can't make it work.
My solution was to get TIM (Teledan's Inventory Manager) script and what I couldn't do in 4+ hours it did in a split-second with 3 tags.
