Breaking Down the Automation You Need for Core Keeper
Automation in Core Keeper starts with understanding the mechanical part system, because if you go into your first run blind, you will waste hours crafting items you never actually use. I learned this the hard way during a run last month where I spent two solid days smelting copper wire and forging gears before realizing I had built a conveyor system that powered nothing. The Core Keeper Mechanical Parts table is deceptively large, and not every component you craft matters equally. Mechanical parts are the crafting components required to build machines, conveyors, pumps, gates, and automaton assemblies. They come in tiers based on the material used. Copper parts appear early when you unlock the furnace and gear assembly. Brass parts arrive once you reach Iron and the associated forge work. Titanium comes much later and opens up the high-efficiency machines that actually move the needle on automation speed. The basic part list includes Gears, Copper Wire, Axles, Bearings, and various plate types. Each machine recipe calls for specific combinations, and the game does not make it obvious which ones matter most. The Gear for example is used in nearly every powered device, while Axles only show up in conveyor systems and certain automaton legs. You do not need to stockpile everything equally.
How I Organized My Workshop Around Mechanics
My current setup runs three separate assembly lines. The first line produces Gears and Copper Wire in bulk, since those two components feed almost every early game machine. The second line handles Brass parts once I unlocked the higher tier forge. The third line is reserved for Titanium assemblies, which I only started building after hitting the late-game mineral deposits under the Frozen Floor. Here is a practical rule that took me way too long to figure out: build your copper gear assembly before you build anything else. A single automated gear press running off a Water Mill or Windmill will produce roughly forty gears per minute. That output rate turns a twenty-minute crafting sprint into something you walk away from and come back to later. I used to hand craft over four hundred gears for my initial conveyor network, which consumed roughly three hours of real time and nearly emptied my copper inventory. The bearings are another component people routinely overlook. You need them for the pump system and for several door mechanisms. Each bearing requires two iron ingots plus one copper wire, which means your wire production has to keep pace with your bearing needs. If your wire output is bottlenecked, your entire pump line stalls out. I solved this by running a dedicated copper ore smelter solely for wire production, separate from my general ingot supply.
Common Mistakes I See in New Runs
The biggest issue is building machines before building power. Conveyors look impressive when you place them down, but they do not move anything without a functional power source behind them. A single Windmill can power approximately five conveyor segments or one small automaton. If you place twelve conveyors expecting them all to work, only five will actually move items. Another mistake is ignoring the automation capacity limits of each power source. Windmills are fine early but become useless past the mid-game. Water Mills scale better. Steam Engines are the real solution for heavy automation, but they require coal and iron piping to operate. I found myself stuck with an enormous conveyor network that only moved items at half speed because I was powering everything from Windmills past the point where they could handle the load. The core problem with early automation is that new players tend to overbuild conveyors without planning their power grid. Place one machine, see it work, then place ten more in the same area assuming the power will scale linearly. It does not. Each power source has a hard cap on how many connected devices it can drive simultaneously. Exceed that cap and the extra machines simply do nothing until you add more power generation.

Advanced Tactics That Actually Matter
Stacking power sources in parallel is the most reliable way to expand automation. Two Water Mills double your capacity without any special crafting. This approach scales cleanly until you transition to Steam Engines, at which point you need to account for coal consumption and the piping infrastructure required to connect them to your machines. Titanium mechanical parts introduce high-speed automaton builders and heavy conveyors that move items significantly faster than their copper equivalents. The upgrade is not trivial though. Titanium parts require access to the deepest biome deposits, and the machines they build consume substantially more power per operation. I would recommend getting your Steam Engine setup stable with brass-tier machinery before attempting a full titanium conversion. One edge case that cost me a lot of time: automaton repair parts use a completely separate resource pool from standard mechanical parts. Killing enemies and looting chests drops these repair components randomly, and they do not craft. When my automaton broke mid-run and I had no spare parts, I was forced to abort a major expansion project until I could find more. I now keep a dedicated storage chest labeled Automaton Parts and put every dropped unit in it immediately. This prevents the panic of running out at the worst possible moment.
What This System Does Not Handle Well
The mechanical parts system in Core Keeper has real limitations. There is no automated smelting yet, which means every ingot still requires manual placement into the furnace. The game also does not track your mechanical part inventory efficiently. If you need two hundred gears and five hundred bearings, there is no quick-reference screen telling you exactly what you are short on. I built a simple spreadsheet tracking my part requirements versus my production rates, and it saved me from multiple bottlenecks. Crafting queues are another missing feature. You cannot queue up a batch of parts and walk away. Every crafting action requires you to initiate it manually, which creates a micro-management loop that becomes tedious once your workshop grows past a certain size. The community has discussed this repeatedly, and nothing has changed as of the latest patch. If you are just starting out, focus on copper gears and wire first. Build a small automated gear press, establish a steady copper smelting loop, and expand from there. Do not chase titanium parts until you have a functional steam power grid and a reliable coal supply. The progression is straightforward once you stop trying to automate everything at once.
