Five decisions that prevent factory rework
The best Sandustry tips are layout habits: keep one working module visible, separate matter types, and fix output capacity before increasing input. These choices matter more than a guessed production ratio because the world is destructible and Early Access behavior can change.
Use C, Ctrl+C, and Ctrl+V for repeated construction
The official Beginner's Guide confirms that `C` selects a structure, while `Ctrl+C` and `Ctrl+V` speed up repeated construction. Keep a clean, working section of the factory as a reference module. Copy it only after checking its input, output, height, and fluid routes.
A copied layout is a starting point, not proof that the new location has the same terrain. Recheck the landing area and available buffers after pasting. This is especially important for Shakers, Kinetic Presses, and any route that depends on a clear fall or flow.
Keep solid and liquid logistics visually separate
Conveyor Belts, Launchers, and Filters move solid pixels, while Pumps, Pipes, and Liquid Vents handle liquids. Place the two families in different corridors when possible. A clear separation lets you identify whether a stopped machine lacks an input, has a full output, or is behind a blocked fluid path.
Leave an inspection gap near every Filter, Grabber, and conversion point. Empty space is a maintenance tool in a destructible factory: it gives you a route to remove a pile, replace a structure, or redirect a by-product without erasing an entire room.
Use Filters before a mixed line becomes opaque
Filters isolate by-products on busy lines. Copper Ore and Sand can share a route before a Filter divides them, but a Smelter should receive the material its page documents. Add the split before overflow, and send the unwanted branch to a real destination rather than a dead-end pocket.
When editing a Filter, pause the feeder and let the existing line settle. Then test one material at a time. This makes it easier to spot a wrong filter rule instead of blaming the downstream machine for a mixed input.
Use early Fluxite on the Grabber path
Grabber capacity and capabilities are useful early Fluxite upgrades according to the official guide. Choose them when manual handling is the action slowing your next objective, but do not assume one universal priority for every save. Read the current upgrade text and keep enough Fluxite for the next confirmed requirement.
Leave puzzles and return with better tools
Some puzzles are intended to be revisited after new tools or resources are unlocked. Mark a blocked location, return to the factory, and improve the logistics or research path instead of forcing an interaction you cannot yet explain. The same principle applies to creatures, matter-state conversions, and lava handling: learn the documented interaction first, then automate it.
Small checks that save a rebuild
Before scaling a chain, ask four questions: Is the input in the correct matter state? Is the next machine's output lane empty? Can you reach the Filter or Grabber? Does the route depend on a version-sensitive flow or height rule? If any answer is unclear, build a tiny test module and record what the current build actually does.
These habits keep the factory flexible while the game develops. Exact values not present in the checked sources are to be confirmed, and community examples should be cross-checked with the official Beginner's Guide after each update.
Sources and evidence
Official pages establish the core mechanics. Community findings are labeled separately and should be checked again after an Early Access update.
