Assembly Complex

The Assembly Complex is a production line: a conveyor runs down the middle of a long hall, and a work station stands beside it every two blocks. Every station works on its own, like an Assembler of its own, and together the stations build parts that need several steps one after the other: advanced circuits, laser optics, precision and quantum frames.

How it works

The complex has three kinds of work. For every station it tries them in this order:

  1. Step recipes (Assembly Line): the workpiece rides the conveyor from station to station; each step needs a station of a certain type, in the right order along the line. A step recipe takes the whole line: when one can start, the stations finish what they are doing, start nothing new, and then the line runs the step recipe alone.
  2. Assembly recipes: the recipes of the Assembler. Every station runs one at a time; a recipe that names a station type only runs at a station of that type.
  3. Crafting patterns (with a Pattern Library): the stations craft the game's real crafting recipes from the 27 pattern cards in the screen, one card after the other.

All stations share the input slots, the fluid tank, the output slots and the energy buffer.

Rules

  • Size: 5 wide, 4 high and 2 to 10 stations long: two blocks of length per station plus the two end walls (6 to 22 deep). The complex finds its length by itself, starting from the block behind the controller.
  • Edges and corners: only Industrial Casing.
  • Walls, floor and roof: Industrial Casing, Industrial Sight Glass, at most one Pattern Library, ports and the controller.
  • Conveyor: a Conveyor on every floor block along the middle of the hall, from the front wall to the back wall, without gaps.
  • Stations: the length of the hall is cut into modules of 2 blocks, counted from the controller wall. Every module needs exactly one station, on the floor directly left or right of the conveyor, in either block of the module.
  • Inside: apart from the conveyor and the stations only air.
  • Energy Input Hatches: up to 4.
  • Controller: in one of the two short (5 wide) end walls, front facing out, with the inside directly behind it.
  • Ports: Item Input Port, Item Output Port, Fluid Input Port and Energy Input Hatches. Every port works only on its outer face.

The order of the stations along the line is up to you. The Build Projector suggests one, repeating the six types in this order: Robot Arm, Press, Laser Welder, Soldering, Inspection, Quantum Manipulator.

The stations

Station Base load (pattern crafts)
Robot Arm Station 1,000 E per tick
Press Station 1,000 E per tick
Laser Welder Station 4,000 E per tick
Soldering Station 4,000 E per tick
Inspection Station 4,000 E per tick
Quantum Manipulator Station 64,000 E per tick

The base load is what a station uses while it crafts a pattern. Assembly recipes and step recipes use the energy of their recipe instead.

Step recipes

The workpiece only moves forward along the conveyor, from the controller wall to the back. The line can do a step recipe when it has a station for every step in that order; other stations may stand between them.

In Out E/t Ticks
2 × Basic Circuit, Superconductor Wire, Silicon Wafer Advanced Circuit 4000 300
any Diamond, 2 × Amethyst Shard, 2 × any Gold Ingot Laser Optic 6000 300
Industrial Frame, 4 × any Precision Alloy Ingot Precision Frame 4000 400
Precision Frame, Stabilized Matter, Quantum Processor Quantum Frame 64000 400

Warning

The quantum frame needs its own order The quantum frame needs Press, then Quantum Manipulator, then Inspection. The suggested order has no Inspection behind the Quantum Manipulator at any length, so the suggested line never makes it. Move an Inspection station behind the Quantum Manipulator.

Assembly recipes

These are the Assembler's recipes (up to tier IV here). A recipe with a station requirement, such as the superconductor wire, only runs at a Laser Welder.

In Out E/t Ticks
Silicon Wafer, Polymer Sheet, 2 × any Copper Wire, any Conductive Alloy Ingot 2 × Basic Circuit 400 100
6 × any Copper Wire, any Steel Rod Copper Coil 200 100
Machine Frame, 2 × any Conductive Alloy Ingot, 2 × Polymer Sheet Industrial Frame 500 160
4 × any Steel Plate, 4 × any Steel Rod Machine Frame 300 160
any Steel Gear, Copper Coil, any Steel Plate Servo Motor 300 100
any Precision Alloy Ingot, 100 mB Liquid Nitrogen 4 × Superconductor Wire 2000 200

Crafting patterns

  • Put a Pattern Library into a wall. Without it the pattern cards do nothing.
  • Encode Pattern Cards in an Assembler and put up to 27 of them into the card slots.
  • A free station takes the next card whose pieces are in the input slots and crafts it in 1 second at its base load. The crafts are real: the result and the remainders (such as empty buckets) come out.
  • Recipes the server does not allow to be automated (data pack lists and works.assemblerBlockedRecipes (default , allowed comma-separated ids)) do not run, and neither do crafts whose result carries extra data.

Energy

  • The energy buffer holds 4,000,000 E, multiplied by the speed factor of the Plant Speed Modules.
  • Every busy station draws the energy of its run in every tick; when the buffer holds less, that station waits and keeps its progress.

Important

Energy grows with the stations The example has a tier 3 hatch (64,000 E/t): 5 busy stations crafting patterns need 14,000 E per tick, and a tier 1 hatch (1,000 E/t) would carry only one Robot Arm or Press. The Quantum Manipulator and Plant Speed Modules need more: add hatches or use tier 4.

The screen

  • Bars for energy and the fluid tank, the progress of the first busy station.
  • Nine input slots, nine output slots, the 27 pattern card slots below and the module slot at the right edge.
  • The status line and a line with the number of stations and whether there is a Pattern Library.

What the status lines say

Status Meaning
Stations busy: 3 / 5 Three of five stations are running.
Stations busy: 5 / 5 (2 waiting for energy) Five stations have started; two of them wait for energy.
Waiting for energy A workpiece on the line waits for energy.
Workpiece on the line (3 steps) A step recipe runs on the whole line.
Step recipe waits for the stations A step recipe can start; the stations finish their runs first.
Result changed – nothing used A pattern no longer gives what was encoded; nothing was used.
Pattern recipe no longer exists The recipe of a pattern card is gone (a data pack changed).
This recipe cannot be automated The server blocks this recipe for machines.
5 stations, pattern library The line has five stations and a Pattern Library.
5 stations, no pattern library Without a library the pattern cards are not used.

Automation

  • Pipes put items in through the Item Input Port and fluids through the Fluid Input Port; only what an assembly recipe, a step recipe or a pattern card needs is accepted. Pattern cards can be inserted the same way.
  • Items can only be taken out of the output slots.
  • A Grid Monitor can pause the complex.

Too many ports of one kind At most 4 Energy Input Hatches and one Pattern Library.
Port not allowed here Only item ports, the Fluid Input Port and Energy Input Hatches work.

Breaking the controller

The items in the slots drop, together with the inputs of the runs in progress. The fluid tank and the stored energy are lost.

In the world

The conveyors run along the line and the stations turn towards them. Each station works on what it makes, and finished products ride the conveyor to its end.

Tip

Plan the line for your recipes Look at the steps of the recipes you want, then place the stations in that order. One line can hold several step orders at once: Robot Arm, Press, Laser Welder, Soldering, Inspection covers all three tier III step recipes.
