Your First Iron Supply Factory Line

full game 1.009.1 ·

On this page

Start with one product: Supply: Iron. Its factory chain turns Iron Ore and Coal into Iron Ingots at a Smithy, then turns the ingots into supply crates at an Assembly bench. Check each connection before extending the line.

FIND YOUR NEXT CHECK

Check an iron supply line, one stage at a time.

Trace ore and coal to Iron Ingots, then Supply: Iron. Stop at the first stage that does not move.

YOUR NEXT STEP

Which stage needs attention?

Use the first missing stage rather than replacing the entire line.

Follow what you observe

Changing an earlier answer clears the later branch. Your observations guide the next check; they do not prove a single cause.

Which stage needs attention?

Use the first missing stage rather than replacing the entire line.

Read all possible checks
  • The line does not run: Check the operator, selected recipes and conveyor connections, then the area-power total. A carousel is a power source, not proof the line can run.
  • Ore or coal is not entering the Smithy: Check the input connection and selected recipe. Next check
  • Ingots are made but not reaching assembly: Follow the Smithy’s output connection to the Assembly bench input. Next check
  • Assembly does not produce Supply: Iron: Check its selected recipe and incoming ingots. Next check
  • Crates exist but are not delivered: For the five-crate example, carry the output crates to Town Warehouse supply pallets and check the selected order’s completed state. A factory chest and stock shown on the board are not proof of a finished order.

Does the selected Smithy recipe receive both inputs?

Its recipe lists ore and coal. An item in a chest elsewhere is not proof it reached the machine.

Read all possible checks
  • Both are reaching it: Check assigned worker, task requirements and factory capacity, then inspect the current craft status.
  • An input is missing: Inspect that input’s stock and conveyor connection before changing the recipe.
  • Not checked: Observe the machine’s actual inputs and compare with its recipe list.

Is there room on the connected output belt?

Finished output waits when the connected receiving cell is occupied.

Read all possible checks
  • Yes: Follow the next segment and confirm it reaches the selected Assembly bench recipe.
  • No: Clear the downstream blockage or destination capacity, then observe the same output.
  • Not checked: Inspect the first receiving belt cell and its downstream destination.

Is the factory Supply: Iron recipe selected and supplied?

The factory recipe has different requirements from the ordinary woodworking-bench recipe.

Read all possible checks
  • Yes: Check the assigned worker, capacity and output space. If it still fails, record the exact station state.
  • No: Select the factory recipe and prepare its input quantity.
  • Not checked: Open the Assembly bench recipe and inspect the incoming ingots.

One batch: Iron Ingot

Factory Smithy recipe only. The number of batches applies to this recipe, not the entire supply line.

One batch: Supply: Iron

Factory Assembly bench recipe only. Supply its required ingots through the line; do not add the ordinary woodworking recipe costs.

Worked example: five iron supply crates

  1. Start with the later five-crate order

    Before starting: the Factory is accessible, its machines and belts are unlocked, and Jack’s five-crate Supply: Iron order is available. Select that order in an active board slot. This example starts with zero credited delivery and no existing iron stock; avoid another active order consuming the same crates. Success: the active order asks for 5 Supply: Iron. If you see the initial 1-crate Workshop Hours order, use the iron delivery guide first; that quest precedes Factory access.

  2. Prepare the production inputs and separate construction costs

    For this fresh five-crate order, the base recipe chain is 40 Iron Ore + 40 Coal → 40 Iron Ingots → 5 Supply: Iron. Each ingot needs 1 ore and 1 coal; each crate needs 8 ingots. Select 5 batches of the factory crate recipe in the preparation list. For one crate’s upstream inputs, select 8 batches of the factory ingot recipe and repeat that amount five times. Check Smithy I and Assembly bench I construction separately, plus input storage, belts and power sources. If you already have stock or credited deliveries, check the remaining order before producing this full amount.

  3. Connect one Smithy to one Assembly bench

    Build or use Smithy I and Assembly bench I. Queue the factory Iron Ingot recipe at the Smithy and factory Supply: Iron at the Assembly bench; assign a capable zombie operator to each. Connect the Smithy output by belt to the Assembly bench input and provide a final output belt from the bench. Use the area-power check below and ensure the Factory is not paused. Success: both machines show the intended queued recipe and an assigned operator. If a worker cannot start, inspect the displayed tool or mastery requirement; a power surplus alone does not satisfy those checks.

  4. Feed ore and coal into the selected recipe

    Put Iron Ore and Coal into the supplying conveyor storage. In its output-slot controls, select ore for one connected outgoing feed and coal for the other, then connect those belts to the Smithy inputs. Success: the required items travel to the machine and its craft starts after both inputs arrive. If one ingredient stops, inspect the stock in that supplying storage, its chosen output item, belt direction and the queued recipe. Materials in your bag or an unrelated chest do not prove that the machine received them.

  5. Watch the ingot leave and reach assembly

    With the inputs supplied and the Smithy working, inspect its first output cell and follow the ingot toward the Assembly bench. Success: the ingot leaves the Smithy, travels downstream and is accepted for the queued crate recipe. If it remains at the output, inspect the first receiving cell and clear the downstream obstruction or full destination. If it reaches assembly but is not accepted, check the bench’s crate recipe and whether a previous output is still waiting.

  6. Collect five crates from the final output

    Let the Assembly bench receive 8 ingots for each crate. Success: Supply: Iron appears on its output belt. With a free overhead carrying slot, interact with a crate on the belt to pick it up, then carry it to a supply pallet in the Town Warehouse or Warehouse Cellar. Repeat until this order has received its five crates. This example uses manual final delivery; it does not assume that any factory chest is connected to town order storage. If no crate appears, check incoming ingots, the operator, the queue and free output space.

  7. Deposit on a supply pallet, then check completion

    While carrying a crate, interact with a supply pallet that can accept it. The delivery handler checks active orders and consumes matching goods from the Town Warehouse and Warehouse Cellar pallets. Success: this nonurgent order gains credited delivery and reaches its completed state after 5 crates. If the board only shows available stock, recheck that this specific order occupies an active slot and that the goods reached a supply pallet, not an ordinary chest. One crate is only part of this five-crate order.

  8. Claim the order reward; keep the earlier quest separate

    Select the completed order on the board to claim its reward. Success: its active slot is freed and the repeatable order is marked completed for the week; do not mistake its reset counter for a lost delivery. This later five-crate order has no Town Supplied hand-in requirement in the reviewed order flow. For the earlier one-crate Workshop Hours quest, the separate finish condition is Jack’s Town Supplied conversation after that specific initial order is finished. If your journal still disagrees, record the quest and order states instead of repeatedly delivering extra iron.

Prepare two goals together

Enter your inventory once to see what to build first and what is still missing.

1. Add the buildings you want

“A second building” means another copy of the same building, not the second goal in your plan.

Your plan · materials are reserved in this order

2. Enter your carried materials

Regional storage, machine contents, other qualities and fuel are excluded. Reservations do not spend items.

3. Check allocations and missing materials

Preview state record

Follow the product through the line

  1. Inputs: bring the selected recipe’s ore and coal into the Smithy through its input connections.
  2. Smelting: select the factory Iron Ingot recipe at the Smithy .
  3. Assembly: connect the ingot output to an Assembly bench with the factory Supply: Iron recipe selected.
  4. Delivery: route the crate output toward the appropriate supply storage. Check the order separately using the iron delivery guide .

Assign an operator to each workstation and connect the stations with conveyor belts. Area power is a separate total from that operator: negative-quality belt parts against engines and carousels. This is a production-chain reference, not a tested floor plan.

Ordinary iron and factory iron

The ordinary and factory recipes reference the same Iron Ingot item. A supply problem therefore does not establish that the metals are incompatible. Check the exact recipe and how its station receives inputs. A regional chest does not substitute for the factory machine’s conveyor connection.

Read the preparation lists separately

Choose the ingot recipe, crate recipe, Smithy placement or Assembly bench placement above. Batch counts apply to the selected recipe only; construction is paid once. The area-power check below includes only the belt parts and sources you count. It does not include per-machine power draw, throughput, minutes, a minimum zombie crew, or a floor plan.

Bioreactor operation and its separate output

For ordinary workbenches use zombie troubleshooting ; for regional inventories use storage and transport .

Area power and the stop you can see

Count only objects in this belt area. A conveyor, underground conveyor, supply station or splitter contributes −1. A zombie engine contributes 5. A carousel contributes 7, or 10 when Belt Master is active. Smithies, assembly benches and chests are not in this total.

YOUR NEXT STEP

Enter the belt area

Included: the belt parts and power sources you enter. Excluded: per-machine power draw, throughput, minutes, a minimum zombie count, and any floor-plan layout. Build a station once; recipe batches stay on the preparation list above.

Keep the line running

Follow one product from input delivery through the selected recipe, finished-output pickup, the next batch and destination storage. Supply and output connections are separate checks; an item available elsewhere does not prove this machine can use it. For ordinary workbenches, inspect the appropriate Supplier or pickup arrangement rather than copying a factory belt requirement.
