Caterium on the Edge of the World
My first Caterium setup! An industrial outdoor factory, color-coded yellow! Roofs are overrated anyways. This factory provides Quickwire to my Dimensional Depot and Caterium Ingots to several nearby factories.
1x Mk2 Miner on a Pure node provides 240/min Caterium Ore, which is smelted by 8x Smelters running at 66.667% to produce 80/min Caterium Ore. (This is definitely not because I incorrectly planned the factory based on Iron Ore smelter recipes and forgot that smelters consume Caterium Ore at a higher rate).
From here, a single Constructor makes Quickwire, which goes to a storage container that feeds a Dimensional Depot uploader. Excess Caterium ingots feed a conveyor belt that transports them to nearby factories, and any excess gets sunk.
One wonders where all the Caterium Ore comes from. Just looking at sheer volume, this rock spire shouldn't have that much minable material...
