How to use:
- Design your process in FactorioLab.
Disable asteroid crushing, recycling, and other cyclic recipes. The link above already has this set up.
- Hide the inputs you'll provide externally by clicking on them.
In the screenshot below, sulfur, iron, water, and red and green circuits are external inputs; there will be a sulfuric acid chemical plant.
You might be tempted to set inputs in the Objectives.
Don't do this because you will have to calculate enough input flow to cover the demand (otherwise machines will be generated to make up the remainder). There are cases where you want this, but usually you don't.
- Click the List tab, then click Download CSV.
- Upload the CSV file below.
- Copy the generated blueprint string and paste it into Factorio!
