Factory: belts, crates and porters

When a factory stops, first compare its displayed power demand with staffed Carousel capacity. If power is sufficient, follow the line to its first item that cannot move. Check that item’s destination and recipe before rebuilding the whole route.

For a stoppage before materials reach the underground network, inspect the remote chest and delivery route. For surface stations, supplier coverage and the 1.011 autocraft cycle distinguish qualified crafting from item movement.

Diagnose the stalled stage

What you see	What to inspect
Every line stops together	Carousel assignments and total power
Ingredients reach the bench but no craft starts	Selected recipe, required extension, worker mastery and tools
One unwanted item blocks an input	Chest output filters and the receiving recipe
A finished supply crate sits on a belt	A Supply Station and its assigned Supply Porter
Ordinary materials stop at a Supply Station	Send them to a Conveyor Chest instead
Factory supplies exist but Town cannot use them	Supply Storage and the separate Warehouse porter route

At 41 displayed demand, Belt Master reduces the minimum from two Carousels to one. The capacity comparison shows where the perk saves workers or an entire Carousel.

Conveyors draw items from adjacent chests; turning an arrow does not make the chest ignore that belt. A chest next to an unrelated line can feed the wrong material into it. Set directional output filters or separate the chest from the lane.

Supply crates and ordinary goods need different destinations. A filled Town supply crate belongs at a Supply Station. Intermediate materials and empty crates belong in Conveyor Chests. A porter does not simply collect any item abandoned anywhere on a belt.

Check garden exports

At the Lifting Crane, enable only the crops the factory needs. Then select the outgoing item at the matching Factory storage. Sending several crops down while the bench accepts only one can fill the storage or block the production lane.

A compact Fabric-supply route uses an Assembly Bench with a Spinning Wheel, a qualified operator, Flax input and a Supply Station. Choose Supply: Fabric for Town commerce. Making ordinary thread or fabric at a different workstation does not automatically produce the boxed supply.

Trace marble from the quarry

On Steam 1.011, quarry workers carry their Stone and Marble to the quarry chests themselves. The old extra quarry-assistant job is unnecessary. Transport from those chests to the factory remains a separate task.

Recent mixed-load porter reports show two different problems: a full destination for one material can obstruct the route, while weak quarry production can simply fail to meet factory demand. Inspect the quarry chest, the factory stockpile and the blocked item before changing the number of miners.

Test one shipment

After changing a route, watch one item enter the bench, become the selected product and reach its destination. Then check its delivery to Town. If it reaches the wrong stage, fix that connection before adding another production branch.
