Factorio Blueprints

It's a smelter for when you don't know what you want. There are stations for both iron and copper ore, both of which are activated only when both the ore and corresponding plate are low, which prevents the boxes from overflowing. The plate stations also only activate when there are enough resources to fill an entire train.

The smelter tiles nicely, which allows the reuse of beacons between smelters. It produces four yellow belts with half beacons and tier1 modules, four red belts with full beacons and tier2 modules and four blue belts with full beacons and tier3 modules.
