required mods: cybersyn, bob's inserters, wide chests, pyanadon loading cranes.
put down a "Full Grid" to begin. Attach "Three Stops" to the sides. Add "Extra Stop" if you need more stops.
attach requester or provider stations to the stops, orient correctly, and line up the power poles for correct placement.
Use 1-1 trains.
I typically default to requesting 1000 solid items at a time, or 20,000 units of fluid. The premade station combinators assume these numbers, they are set to refill if less than 500 solid items are present or 10k fluid. If you mess with these settings make sure the trains have enough capacity for what you're doing. Items that stack in units of 10 need tweaking (like some pyanadon items, nexelit batteries for instance).
Filters on fluid requesters need to be manually set. Settings on fluid providers need to be set by paramaterization when placing, it will prompt you.
before you've unlocked loading cranes, you'll need to use the "before cranes" requester and provider stations.
cranes don't like rotating 90 degrees, so if you want left-right oriented stations you might need to craft them yourself, I didn't make prints for them.
