Here are some screenshots of a recent Factorio game I played where the goal was to get to personal roboport as quickly as possible.
- One column of iron (upgrade to red belts as needed)
- One column of copper
- One column of integrated iron-to-steel
Leave enough room at the end of the iron column to make ammo and grenades.
Bring the iron and copper belts together so that they are 9 spaces appart and build green circuits on one side of a belt. Build gears on the other side of the belt.
Errata:
- the last gear assembler is erroneously configured for electric motors
Bring these together to create a 4-belt bus of:
- steel
- copper
- iron
- gears + circuits
Create a half-belt of copper plates + gears to feed 6 red science assemblers.
Branch off gears + circuits and iron plates to feed belt and inserter assemblers. Combine those to feed 8 green science labs. Create overflow chests where appropriate.
Errata:
- You don't need 4 inserter assemblers. In fact, running at full speed, you only need one belt and inserter assembler. However, to accomodate the pre-blue-inserter part of the game, and to ensure lots of overflow as a mall, use 2 assemblers each of belts and inserters.
Branch off a belt of iron plates to feed 2 gear and 2 pipe assemblers. Add an extra pipe assembler feeding an underground pipe assembler to act as a mall.
Branch off a belt of steel to feed 10 engine assemblers.
