Assembler

The Assembler is a small 3D printer for parts. It runs QNet's assembly recipes (frames, coils, motors, circuits) and, with a pattern card, crafts any crafting recipe of any mod by itself. Servo motors and basic circuits for the tier II machines are made only here or in the large Assembly Complex.

Property Value
Tier 1
Energy buffer 20,000 E
Max. input 4000 E/t
Input slots 9
Output slots 3
Upgrade slots 0
Recipe type Assembly

The Assembler window: 1 input slots, 2 progress, 3 output slots, 4 upgrade slots, 5 energy and tank bars, 6 value, status and redstone lines, 7 buttons (redstone mode, telemetry, codex).

The Assembler window: 1 input slots, 2 progress, 3 output slots, 4 upgrade slots, 5 energy and tank bars, 6 value, status and redstone lines, 7 buttons (redstone mode, telemetry, codex).

The screen

  • Left: the energy bar and the fluid tank.
  • Middle: nine input slots (3 × 3), the progress arrow and three output slots.
  • Right: the pattern grid (nine ghost cells), the card slot, the encode button ✎ and the redstone button R.
  • Below: the status line and the pattern line: "no card – assembly recipes", "blank card – set the grid and encode", or the item the card makes.

The Assembler has no upgrade slots.

Assembly recipes

Without a card the Assembler runs the assembly recipes. The ingredients may lie in any input slots, and one ingredient may be spread over several slots. The result goes into the output slots.

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

Note

Recipes for the Assembly Complex Recipes that name a station (such as the superconductor wire, which needs a laser welder) only run in the Assembly Complex. The Assembler skips them, and its tank does not take what only they need.

Crafting with a pattern card

  1. Put a Pattern Card into the card slot.
  2. Lay out the crafting recipe in the pattern grid: clicking a cell with an item puts a copy there, clicking with an empty hand or with the right button clears it. Nothing is used up.
  3. Press ✎. The card now carries the recipe and is named after its result ("Pattern written: …"). With an empty grid, ✎ clears the card ("Pattern card cleared").
  4. Put the ingredients into the input slots, in any order and any slots.

Every craft runs the game's real crafting recipe with the items from the inputs, so the result is exactly what a crafting table would give. Leftovers of the recipe (empty buckets, bottles) come out into the output slots with the result. One craft takes 0.5 seconds and 50 E.

With a card inserted, the input slots only take the items that the card's grid uses. The card can be used in every Assembler; take it out to run assembly recipes again.

Messages when encoding:

Message Meaning
Put a pattern card into the card slot first The card slot is empty.
No crafting recipe makes this pattern The grid matches no crafting recipe.
Recipe … cannot be automated The recipe is on a blocked list, or its result carries extra data (a name, an enchantment).

Blocked recipes

Some recipes must not be automated. A server lists them in the setting works.assemblerBlockedRecipes (default , allowed comma-separated ids); data packs add lists under data/<namespace>/qnet/not_automatable/ as {"recipes": ["mod:recipe_id"]}. Recipes whose result or leftovers carry extra data are always refused, because the Assembler puts out plain items.

Energy

The Assembler takes energy on every side, from a Pipster cable, a generator next to it or any FE or Team Reborn Energy source. When the buffer holds less than one tick of the current run, the run waits and keeps its progress.

Automation

  • Pipes, hoppers and other mods can put items into the nine input slots from every side: without a card only items that an assembly recipe uses, with a card only items of its grid.
  • The fluid tank takes only fluids that an assembly recipe the Assembler can run uses. None of the shipped recipes it runs needs a fluid, so the tank stays empty unless a data pack adds one.
  • Items can only be taken out of the three output slots.
  • When the outputs are full, the finished run waits until there is room.

Redstone

The R button switches the redstone mode: always runs, runs with a signal, or runs without a signal. The line "Redstone" under the status shows the mode in use.

What the status line says

Status Meaning
Idle – waiting for inputs No recipe fits, or the inputs for the card are not complete.
Running A run is in progress.
Waiting for energy The buffer is too low; the progress is kept.
Output full – take the products out The products of the finished run do not fit.
Paused by redstone The redstone mode stops the machine. A Grid Monitor that pauses machines shows the same text.
This recipe cannot be automated The card's recipe was blocked after it was written, or its result now carries extra data.
Result changed – nothing used The real recipe no longer gives what the card says (a data pack changed it). Encode the card again.
Pattern recipe no longer exists The card's recipe was removed. Encode the card again.

Building it

The Assembler needs a crafting table, a steel gear, iron plates and redstone. The steel gear comes from the Metal Former.

Crafting Table
→ Assembler
Redstone Dust

Pattern cards come four at a time from paper and redstone:

Paper Paper Paper
Paper Redstone Dust Paper → Pattern Card
Paper Paper Paper

When you break it, it keeps its energy, its fluid and its redstone mode; items, the card and the ingredients of a running job drop. The ghost cells of the pattern grid are lost.

In the world

While it runs, the product is printed on the build plate from the bottom up: the gantry rises layer by layer, the print head moves back and forth over the layer, and small sparks glow at the nozzle. The stepper motors click softly, and the machine gives off a little light.

Tip

Circuits and motors The Industrial Centrifuge and other tier II machines need servo motors and basic circuits. Keep one Assembler for these parts and one with a pattern card for the crafting you repeat most.
