Satisfactory First Iron Line: 20 Plates + 30 Rods per Minute

Pick the output you actually need

Early expansion consumes both plates and rods. The mixed layout below keeps both available without a large manifold or an ingot merger. It uses all nominal ingot supply, so another consumer must take capacity away from an existing branch unless extraction and transport are also changed.

Inspect purity before copying the layout. At 100% clock, Mk.1 extraction is listed at 30/60/120 ore per minute on impure/normal/pure nodes. A Mk.1 belt transports at most 60: a pure node cannot double this plan through that belt. An impure node supports only half the illustrated ingot supply.

Build the mixed line from extraction to storage

Use two connected outputs on each splitter. An unconnected third outlet is fine; a third outlet connected to an empty container is another demand path. That branch can divert ore until it backs up. Do not use an overflow chest as a harmless decoration while checking a two-way split.

Build one branch at a time. The correct recipe, a powered machine and a connected belt are separate checks. Leave room beside each machine to open its interface, and keep output containers accessible for the later count check.

1. Confirm a normal iron node, Miner Mk.1 at 100% clock and a Mk.1 belt leaving its output.
2. Feed an ore splitter with exactly two connected output belts. Route each to a Smelter using the default Iron Ingot recipe: 30 ore/min in, 30 ingots/min out.
3. Route Smelter A directly to one Constructor using default Iron Plate: 30 ingots/min in, 20 plates/min out. Belt its output into dedicated plate storage.
4. Route Smelter B into a second two-way splitter. Feed two default Iron Rod Constructors, each taking 15 ingots/min and making 15 rods/min.
5. Collect both rod outputs in rod storage, using a merger if needed. Do not accidentally merge plates into that same collection path.
6. Check that all six production machines have power and that output storage has room. Let input buffers and belt travel settle before judging rates.

60 ore/min → two-way splitter
  A: Smelter 30 ingots/min → Plate Constructor → 20 plates/min
  B: Smelter 30 ingots/min → two-way splitter
       → Rod Constructor → 15 rods/min
       → Rod Constructor → 15 rods/min

Budget the whole line's power, not just its Smelters

At the cited 100%-clock rates, the production load is 5 + (2 × 4) + (3 × 4) = 25 MW. This includes the Miner, two Smelters and three Constructors; it excludes other equipment on the grid. A single fueled standalone 30 MW burner has a nominal 5 MW margin for this isolated line. One 20 MW HUB burner is 5 MW short if all six machines run.

Those are capacity calculations, not a guarantee of sustained operation. Check burner type, loaded fuel and actual wiring. If your construction area already shares a grid with other machines, budget those too; do not spend the same margin twice.

Diagnose the first failing boundary

Do not solve a stopped Constructor by adding a third Smelter immediately. Open the earliest machine that is not behaving as expected. A full output buffer points downstream; an empty input points upstream. A correct nominal ratio cannot overcome a wrong recipe or a missing belt segment.

A connected third ore branch changes the startup split: while all three outlets accept items, 60/3 gives 20 ore/min to each branch, below either Smelter's planned 30. Once the extra branch fills, distribution changes again. That explains a line that starts slowly and later improves without a recipe change. Disconnect the extra path for this test.

Verify the result in your save

This is a proposed measurement procedure, not a recorded GamerWin result. After the line settles, record plate and rod storage counts, run for 120 seconds with no manual item transfers, then record both counts again. Keep storage unblocked and power continuous throughout. The nominal two-minute increments are 40 plates and 60 rods; startup travel and interrupted cycles invalidate that comparison.

Use change in count divided by elapsed minutes as your observed collection rate. For example, an illustrative 24-plate increase over two minutes means 12 plates/min collected, not proof that the Miner is faulty. Check the plate branch, timestamps and power before drawing a cause from that one number.

Before you play

• Normal node, default recipes and 100% clock confirmed.
• Ore split into two Smelters; one plate and two rod Constructors connected.
• 25 MW production load checked against fueled generation and other consumers.
• Two-minute count check recorded only after buffers settle; no invented test result.
