A simple tier 3 logistic blueprint for early/mid game that builds yellow, red & blue transport belts, underground belts and splitters.
It is obviously NOT a perfect ratio only a "set-and-forget" system to automate tier 1,2 & 3 logistics to grab as you need. There are limiters on the chests, check them if you wish to stack more items. Inputs lines are marked with combinators.
You should replace the wood chests with passive providers once you have a logistics network available.
This is compatible to upgrade directly with my other logistic blueprints and can be upgraded using the upgrade planner tool without any issues.
