How it works

One supply bus from Garden Storage feeds four machine intakes through Conveyor Chests.
Every small and large extension spot is filled, and no belt crosses a spot.
Outputs drop onto a westbound collector that ends in a Chest II buffer.
The kitchen line passes under the collector on an Underground Conveyor pair.
67 power for 65 belt cells and two underground cells, on 3 staffed carousels (84).
