Compact and UPS-friendly 1x1 loaders. Works with train cargo wagons, circuits, filters, and modded belts from Bob's, Krastorio, FactorioExtended Plus, Space Exploration, and Ultimate Belts.
Ucing the mod I've noticed that your "miniloaders" are, effectively, just inserters with limited graphycal texture.
Thjey load ingredients in machines just for the 10 seconds production or 2 products production, wichever is the highest, when a loader has to fill all the slots, if the belts push enough resources.
Am I wrong?
Each miniloader hides a set of very fast invisible inserters, one for each lane of the belt. Lua scripting adjusts pickup and drop points accordingly when the direction of the miniloader is changed.
