Guaranteed Stacked Items from Recyclers

Inputs: 4 scrap input belts Output: 1 central output belt (easily expandable by moving one half of the blueprint)

How it works

• Each pair of recyclers outputs into a chest.
• The chests buffer up to 64 of each item (an arbitrary threshold) to ensure stack inserters can always grab a full stack.
• Circuit logic:
  1. Filters for items with a count greater than 64.
  2. Selects the item with the highest count.
  3. Sets that item as the filter for the stack inserter.
• The stack inserter places a full stack of the selected item onto the output belt.
• The process repeats continuously.

This guarantees that items leave the system as properly stacked belts rather than a mixed stream of partial stacks.

I’m sure the design can be improved, and I haven’t found a clean way to fit beacons into the layout yet.
