Start a small iron line.

Connect one working chain

Community example: Steam discussion replies 4–5, September 28, 2026. Check your current blueprints; this is not a tested tile layout or an optimal machine ratio.

1. Iron ore + coal
2. Conveyors
3. Smithy + worker
4. Output chest

Process schematic, not a placement blueprint.

1. Restore power. Repair the Zombie Carousel and assign workers.
2. Prepare inputs. Establish ore collection and transport, then check ore and coal at the factory’s resource stands.
3. Install a Smithy. Place it near both inputs and assign a worker with sufficient mastery.
4. Connect the line. Run input belts to the Smithy and connect the output to a conveyor chest. Select the iron recipe.

Success check: iron bars arrive in the output chest.

Find where the flow stops

Inputs remain in storage

Check that the chest is connected by a conveyor.

The station stays idle

Check power, worker mastery and the selected recipe.

No finished item reaches storage

Follow the output connection to its chest.

Need to equip the worker first? Follow the zombie assignment steps.

Record one successful batch first

Editorial suggestion: take a screenshot once the line works. Record where the inputs and outputs are before changing it. This makes a later fault easier to isolate.

For warehouse deliveries, see the order checks. This iron example ends at an output chest; it does not demonstrate an automatic warehouse supply line.
