Week 3 Tutorial: Build a Balancer

Design a 5-belt-to-4-belt balancer from splitters and underground belts, then prove it holds under an uneven input.

Before the tutorial#

Bring last week’s save. You’ll need a clear patch of floor and a supply of belts, splitters and underground belts. The factory simulator is a quick way to test a balancer layout before committing belts and splitters in-game.

In the tutorial#

Build your balancer, then starve one input lane at a time and confirm the outputs stay even. A balancer that only works with all five inputs full is not a pass.

Afterwards#

Keep the blueprint — Weeks 6 and 10 both reuse balancer theory at larger scale.
