What it changes
- Belts. Turbo, blue and red belts, underground belts, splitters and loaders become the fastest tier you have.
- Quality. Uncommon to legendary buildings, modules, recipes, filters and requests all become normal, so your robots can build it with what is in your network.
- Modules. Lower them to tier 1 or 2, or remove them. Without modules, beacons do nothing, so they are taken out too.
- Assembling machines and inserters. Assembling machine 3 can become 2 or 1, and stack or bulk inserters can become bulk or fast inserters.
What it keeps working
- Underground belts stay connected. Slower underground belts reach less far, and two pairs of the same tier cannot weave under each other. A pair that would break keeps its tier, and the list tells you which tier you need for it.
- Fluids. Assembling machine 1 cannot take fluids, so recipes such as blue circuits stay in assembling machine 2.
- Module slots. A smaller machine has fewer slots, so modules that no longer fit are removed instead of being lost when you place it.
- Blueprint books. Every blueprint in the book is changed the same way.
What to expect
A slower version makes less: a build made for turbo belts carries half as much on red belts, and machines without modules or beacons craft more slowly. The list shows how the power use changes. Buildings that only exist in Space Age, such as the foundry, stay as they are; the list says so.
How to remove quality from a blueprint in game
You can also use an upgrade planner in Factorio, but it changes one building type at a time and leaves modules and filters alone. This tool does everything in one step and checks the result. To import the new string, see how to import a blueprint.
Every blueprint on BeltPrints has the same tool built in: open any build and use Make it fit your game under the copy button. Want to see what a string contains first? Use the blueprint inspector.
