PneumaticCraft: Repressurized guide for All the Mods 10: To the Sky 1.1.1 to 1.2.1

PneumaticCraft: Repressurized is an industrial-themed tech mod built around compressed air. It has its own power system, an original take on automation, and a very powerful armor set. This pack includes version 8.2.13 for Minecraft 1.21.1.^[1][2]

It's for you if you like machines that work in their own way instead of just plugging into the usual power cables. Compressors are the power generators here: they compress air to build pressure, and pressure tubes carry that air to your machines.^[3][4][5]

What you'll be doing

• Generating and moving pressure with compressors and tubes. The quest book covers this in "Generating Pressure" quest and "Moving Pressure" quest.^[3][4][6]
• Automating item and fluid transport with the Logistics System. It uses frames on your existing inventories and tanks, connected by drones or by tubes with modules attached. The quest book starts it with "Logistics" quest.^[6][7][8]
• Programming drones with the in-game programming widgets.^[9]
• Producing renewable resources, especially Biodiesel.^[10][11]
• Building the upgradable Pneumatic Armor. On its own it's only slightly better than the equivalent iron armor, and upgrades are what make it strong.^[12][13]

Where it fits in the pack

The mod has its own quest chapter, which opens with "PneumaticCraft: Repressurized" quest. The first step is making Compressed Iron Ingot, and the quest suggests blowing up iron in a hole in the ground. Most of the chapter's other quests unlock after that one.^[6]

From there, the early goals are Pressure Tube and Reinforced Stone. The quest asks for 32 Reinforced Stone, and the mod's own guide then points you to a Pressure Chamber. The in-game manual unlocks more sections as you earn advancements, so check it for what to build next.^[6][14]

If you want early gear, "Compressed Iron Armor" quest is the early-game armor set. It's slightly better than iron armor and is repaired with compressed iron ingots.^[6][15]

Welcome to PneumaticCraft! Everything in this mod starts with one material, the Compressed Iron Ingot. The mod doesn't add any ores of its own, so all you need to start is regular iron and stone. The pack's first quest, "PneumaticCraft: Repressurized" quest, has you make that ingot first.^[6][14][16]

Step 1: Make Compressed Iron

Grab roughly a stack of iron (a bit less is fine) and a stack of stone. Throw the iron on the ground and set off a nearby explosion. TNT works, and so does any other explosion. Yes, really! The quest suggests digging a hole, dropping in iron ingots or blocks, and blowing it up.^[6][14][16]

Step 2: Build the basics, in order

1. Make some Pressure Tube. They are how you move compressed air around, and getting them is the task of the quest "Moving Pressure" quest.^[4][6][14]
2. Make Reinforced Stone from Compressed Iron and regular stone. The quest "Reinforced Stone" quest asks for 32 to start, and it calls this one of the most important materials you'll need.^[6][14]
3. Build an Air Compressor (see the recipe below). Put burnable items in it and it makes pressure. The quest "Generating Pressure" quest recommends making at least 3 to start.^[6][18]
4. Craft a Security Upgrade and put it in your machines. The quest "Preventing Explosions?" quest warns that everything can blow up, and this upgrade makes sure machines don't explode.^[6]
5. Build the Pressure Chamber, covered below.^[14]

An easy way to make pressure. It burns solid fuel, so fuel buckets won't work.

Step 3: The Pressure Chamber

The Pressure Chamber is a multiblock made of Pressure Chamber Wall blocks. It can be as small as 3x3x3 or as big as 5x5x5, and the quest "The Pressure Chamber" quest asks for the blocks of the 5x5x5 version. Pipe pressure into a Pressure Chamber Valve with your tubes, and remember to put a Security Upgrade in the valve. Different recipes need different amounts of pressure.^[6]

To get items in and out, place Pressure Chamber Interface blocks on the chamber. Blue on the outside means import, and gold on the outside means export. Place one of each on any face.^[6]

Useful next steps

Once you have Reinforced Stone and pressure tubes, build a Charging Station. It charges and discharges items that run on pneumatic power, such as Drones and Pneumatic Wrenches, and it manages upgrades in items that accept them. After that, the quest book points you to the Manometer to read extra info from machines and the Pneumatic Wrench to move or break your machines and tubes.^[6][18]

Same as in the All the Mods 10: To the Sky 2.0.4 guide

Compressed air is the power system of this mod. Compressors produce it, and Pressure Tubes move it around.^[3][4][19]

Pressure, volume and air

Every pressurizable machine and tool has a volume in mL, which is how much air it holds at 0 bar. The mod uses gauge pressure, so 0 bar is normal atmosphere and -1 bar is a vacuum. Pressure is P = (A / V) - 1, where V is volume and A is the air currently stored. A machine with 5,000 mL of volume holding 20,000 mL of air sits at 3 bar.^[19][20]

Air flows from higher-pressure blocks to lower-pressure ones, and pressure tries to balance out. A small machine connected to a big air reservoir will build up pressure. Leave a tube or machine side open and you get a big air leak, which you can hear as hissing and see as particles.^[19]

Machines may need a minimum pressure to run, but what they actually use up is air, not pressure. Volume Upgrades raise a machine's volume, so each operation causes a smaller pressure drop.^[19]

Pressure tiers

Currently there are three tiers of machine. Tier one resists 5 bar, tier one-point-five resists 10 bar and tier two resists 20 bar. Tier 1.5 was added in the MC 1.18 release as an optional step. It covers things that used to need tier two, like charging tools to 10 bar and getting a Diamond Drill Bit for 3x3 block breaking.^[20]

Tubes have limits too. According to its tooltip, the Advanced Pressure Tube is the strongest type of Pressure Tube, with a max safe pressure of 20 bar. It can be camouflaged and Tube Modules can be placed on it, such as the Air Grate Tube Module.^[21][22]

The Air Canister is a crafting component for any pressurizable item. It has a volume of 3,000 mL, can be charged to 10 bar without exploding, and items crafted with it keep its air.^[23]

Generating air

Compressors are the power generators. The tooltip for the basic Air Compressor says it makes compressed air from any solid-fuel item that can burn in a Furnace, placed in the fuel slot. Fuel buckets do not work there, so liquid fuels need a Liquid Compressor.^[3][21]

Recipe id: pneumaticcraft:air_compressor

• Advanced Air Compressor: its tooltip calls it the tier two version, generating at 50 mL/tick and also producing heat. The higher the heat, the lower the efficiency, and the tooltip says it won't explode when the temperature gets too high.^[21]
• Advanced Liquid Compressor: its tooltip gives a generation rate of 50 mL/tick, with the same heat and efficiency behavior.^[21]
• Flux Compressor: its tooltip says it converts Forge Energy into air at a base efficiency of 40%, so 100 FE gives 40 mL. Speed Upgrades reduce that efficiency slightly, and the compressor generates heat that must be dissipated to avoid efficiency loss.^[21]
• Electrostatic Compressor: its tooltip says it produces 200,000 mL of air instantly when hit by lightning. A grid of Iron Bars or Lightning Rods raises the strike chance, as does a column of up to 10 more directly above it. Strikes are very poor in clear weather, better in rain and much better in thunderstorms.^[21]

For the Electrostatic Compressor, the grid works out to 5 blocks horizontally and 5 vertically, with up to 250 blocks per grid. Add a column of grid blocks below it to ground excess energy. The tooltip says the accepted grid blocks might be modified by a modpack. This pack's config files aren't available, so check JEI in game.^[21]

Heat

Heat moves from hotter to colder blocks, and only between blocks that support heat. A bigger temperature difference means faster flow. Each material has a thermal resistance, which sets how fast heat spreads. It also has a thermal capacity, which sets how slowly its temperature rises or falls.^[24]

Exposed machines leak heat into the air. To stop that, make sure no face touches an air block. Any non-conducting block works, even a trapdoor or slab. Blocks of Compressed Iron conduct heat very well, so they're handy for adding faces to attach heat sinks to.^[16][24]

Adjacent blocks and fluids act as static heat sources, such as lava, ice, torches and more. A Vortex Tube is a dynamic source that turns pressure into heat and cold. Heat Pipes carry heat without any thermal link to neighboring air or fluid blocks. All block heat properties are defined in datapacks, so pack makers can change them.^[25]

A vanilla Furnace next to a dynamic heat source, such as a Vortex Tube or an Advanced Air Compressor, can run purely on heat with no solid fuel. This starts at 100°C and speeds up as it gets hotter. It also works for Blast Furnaces and Smokers.^[25]

Heat plays a part in other machines too. The Etching Tank can be heated above 50°C for faster etching, at the cost of slowly using up Etching Acid.^[21]

Assembly line

According to its tooltip, the Assembly Controller controls any connected assembly machine, and the machines connecting those machines, and so on. To start the assembly you put a program in its program slot. The Drill & Laser program is made by combining the separate Drill and Laser programs.^[21][22]

Assembly Program: Drill & LaserMod recipe

Crafting Shapeless

• Assembly Program: Laser
• Assembly Program: Drill

Recipe id: pneumaticcraft:assembly_program_drill_laser

• Assembly Platform: its tooltip says it holds items in place for drilling and lasering.^[21][22]
• Assembly Drill and Assembly Laser: their tooltips say they work on an Assembly Platform directly next to them, not diagonally.^[21][22]
• Assembly IO Unit (import) and Assembly IO Unit (export): per their tooltips, the import unit transfers items from an input inventory to a platform, and the export unit transfers items from a platform to an output inventory.^[21][22]

You can swap an import IO unit for an export one, and back, with a shapeless crafting recipe.^[22]

Moving items and fluids

• Air Cannon: its tooltip says it transports items through the air. You make a GPS Tool, right-click the destination block with it, then insert the tool in the cannon's GPS slot.^[21][22]
• Aerial Interface: per its tooltip, it uses the inventory of the player who placed it as its own, so hoppers can move items in and out and they are added to or removed from that player's inventory. Drones or Logistics Frames could keep that player supplied with 64 torches, for example.^[21][22]
• Elevator: its tooltip says it needs air pressure and Elevator Frames on top of the Elevator Base. Redstone strength sets the height, with 0 meaning 0% extension and 15 meaning 100%. Elevators joined sideways share floor names when their topmost bases are at the same height.^[21]
• Gas Lift: its tooltip says it places Drill Pipes downwards until it hits a liquid, digging through solid blocks on the way, which uses pressure proportional to the block's hardness. The minimum pressure required increases proportionally to the working depth.^[21]

Crude Oil is the mod's only world generation, and its lakes are far more likely deep underground. A Gas Lift is the recommended way to pump it. An early way to carry it home is a Small Tank, which keeps its contents when broken.^[26]

Reading a machine's GUI

Most machines have side tabs. Redstone behavior sets how it reacts to redstone, Upgrades shows what it accepts, and Pressure Status shows pressure and volume. The Problems tab tells you why a machine isn't working, so check it first when something stalls.^[27]

Building for reliability

Chunks are 16x16 in the horizontal axes, and machines only run while their chunk is loaded. If you want processing while you're away, chunkload the build. Keep it inside chunk boundaries, since a half-loaded build behaves unpredictably. Keep multiblocks like the Pressure Chamber within a single chunk if you can.^[28]

Compressed Iron in this pack

Compressed Iron is the base material for most recipes. You can make it by throwing iron ingots on the ground and exploding them, but you lose around 20% of them. A Pressure Chamber avoids that loss, though you need some Compressed Iron to build the chamber itself. This pack changes the recipe that turns a compressed block back into a Block of Compressed Iron, shown below.^[16][22]

PneumaticCraft is all about pressure, and this pack's quest chapter walks you up through it in a clear order. Everything starts with Compressed Iron, then pressure, then oil, then plastic, then circuit boards and the Assembly Line. Here is the route, then a closer look at each stage.^[6]

1. Make Compressed Iron Ingots with "PneumaticCraft: Repressurized" quest.^[6]
2. Craft 32 Reinforced Stone ("Reinforced Stone" quest) and your first Pressure Tube ("Moving Pressure" quest).^[6]
3. Start generating pressure with the Air Compressor ("Generating Pressure" quest).^[6]
4. Protect your machines with the Security Upgrade ("Preventing Explosions?" quest), then build the Pressure Chamber ("The Pressure Chamber" quest).^[6]
5. Collect Crude Oil ("Crude Oil" quest), make heat, and build the Oil Refinery ("Oil Refinery" quest).^[6]
6. Turn LPG into Molten Plastic in the Thermopneumatic Processing Plant, then into Plastic Sheets ("Plastic" quest).^[6]
7. Order a PCB Blueprint from Amadron and work through the PCB chain to a Finished PCB, which leads on to the Assembly Line.^[6]

Step one: Compressed Iron

The quest tells you to dig a hole, throw in iron ingots (or blocks) and set off TNT. The in-game guide warns that you lose around 20% of your ingots this way. You can avoid the loss by crafting Compressed Iron in a Pressure Chamber, but you need some Compressed Iron to build that chamber, so a little early loss is unavoidable.^[6][16]

Compressed Iron IngotMod recipe

Explosion Crafting (pneumaticcraft)

• any iron ingot

Recipe id: pneumaticcraft:explosion_crafting/compressed_iron_ingot

This is the explosion recipe: any iron ingot becomes a Compressed Iron Ingot.

This pack also changes a recipe that turns Mystical Agriculture's Compressed Iron Essence into a Compressed Iron Ingot, which gives you a second route to the ingots.^[17]

Pressure tiers

The in-game guide currently lists three pressure tiers for pneumatic machines. Tier one machines nominally resist 5 bar, tier 1.5 machines resist up to 10 bar, and tier two machines resist up to 20 bar. Tier 1.5 is an optional tier, mainly intended to give access to things that used to be tier two only, such as charging tools to 10 bar and obtaining a Diamond Drill Bit, which allows 3x3 block breaking.^[20]

The Reinforced Pressure Tube holds 10 bars of pressure, which matches the tier 1.5 limit. The Advanced Air Compressor is the tier two version of the Air Compressor, with a maximum safe pressure of 20 bar. It must be cooled, because its efficiency drops as it heats up, down to the point where no air is generated at all.^[6][20][29]

Tier one: pressure and the chamber

The quest recommends building at least 3 Air Compressors to start with. You feed them burnable items. If you want other pressure sources, the quests also cover the Liquid Compressor and the Thermal Compressor, which turns a hot side and a cold side into pressure.^[6]

Everything in this mod can blow up, so put a Security Upgrade in your machines. The Pressure Chamber is a multiblock that can be as small as 3x3x3 or as big as 5x5x5, and the quest asks for the blocks for the 5x5x5. Pipe pressure into a Pressure Chamber Valve, put a Security Upgrade in it, and place one importing and one exporting Pressure Chamber Interface on any face.^[6]

Oil, heat and plastic

Crude Oil can be found naturally on the surface of the overworld. For larger amounts, use a Seismic Sensor to find a deposit, then drill with a Gas Lift filled with Drill Pipe, which needs pressure to work.^[6]

The refinery needs oil and heat. The Vortex Tube splits pressure into hot and cold air, Heat Pipe carries the heat, and a Heat Sink on the cold side boosts production. The refinery is a 1x1x5 multiblock with one Refinery Controller at the bottom and four Refinery Outputs on top. It produces Diesel, Kerosene, Gasoline and LPG, and Thermal Lagging on the sides helps keep it warm.^[6]

LPG is the fuel you need. Pump it into the Thermopneumatic Processing Plant along with Coal and heat to get Molten Plastic. Place that on the ground, or store it in a chest with a Heat Frame attached, to get a Molten Plastic.^[6]

PCBs and the Assembly Line

With plastic you can start on PCBs. Make Empty PCBs in the Pressure Chamber, then buy a PCB Blueprint from Amadron using the Amadron Tablet. The quest lists it at 8 Emeralds. Next, charge the Empty PCBs in a UV Light Box, which needs pressure and sunlight. Then etch them in an Etching Tank with Etching Acid and heat to get an Unassembled PCB.^[6]

Finally, craft the Unassembled PCB together with 2 Capacitors and 2 Transistors to get a Finished PCB. The quest chapter then moves on to the Assembly Line, starting with the Assembly Controller and the import and export IO units.^[6]

Side branches

• Lubricant comes from Diesel and is used to make Drill Bits for the Pneumatic Jackhammer. The Netherite Drill Bit quest follows both the Diamond Drill Bit and the Jackhammer.^[6]
• Yeast leads to Ethanol, then Biodiesel, which the quests say can make Lubricant and Molten Plastic.^[6]
• The Upgrade Matrix means an upgrade costs 1 Lapis instead of 4.^[6]
• Compressed Iron Helmet and the rest of the Compressed Iron Armor set are an early-game option, slightly better than Iron Armor.^[6][15]

PneumaticCraft ties into several other mods in this pack through changed or added recipes. Most of them revolve around Compressed Iron, Crude Oil and Plastic, so you'll bump into them even if you never plan a big pressure setup.^[17]

Compressed Iron everywhere

• Mystical Agriculture: the pack changed the recipe that turns Compressed Iron Essence into a Compressed Iron Ingot, so you can get the ingot from essence as well.^[17]
• All the Compressed: the pack changed the recipes that convert between Block of Compressed Iron and Block of Compressed Iron 1x, in both directions.^[17]
• Patchouli: the pack changed the Guide Book recipe so it uses a Book and a Compressed Iron Ingot.^[17]
• Mekanism: the pack changed the recipe for the Radiation Shielding Upgrade. It now needs a Module Radiation Shielding Unit, a Compressed Iron ingot and a Pneumatic upgrade component.^[17]

Creative items from the Pressure Chamber

The pack adds two Pressure Chamber recipes that use the ATM Star. One makes the Creative Compressed Iron Block, the other makes the Creative Compressor.

The pack's quest book covers this mod in the "PneumaticCraft" chapter. It follows the mod's own progression: pressure first, then oil and plastic, then circuit boards, then assembly lines and armor. The quests don't cover everything the mod has, but they point you to JEI, the tooltips and the PCB:R.^[6]

Getting started

The chapter opens with "PneumaticCraft: Repressurized" quest, which asks for Compressed Iron Ingot. The quest suggests digging a hole, throwing in iron and blowing it up with TNT. Some of the iron gets lost in the blast, but that's the accepted cost.^[6]

From there the chapter branches. "Moving Pressure" quest asks for Pressure Tube, and "Reinforced Stone" quest asks you to start by making 32 Reinforced Stone. Several side quests also open straight away: Liquid Hopper, Transfer Gadget, Crop Support, Omnidirectional Hopper and the "Compressed Iron Armor" quest set. The fluid tank line also starts here, with Small Fluid Tank, then Medium Fluid Tank, Large Fluid Tank and Huge Fluid Tank.^[6]

Pressure, tools and the Pressure Chamber

1. "Generating Pressure" quest asks for an Air Compressor. The quest recommends making at least 3 to start with.^[6]
2. "Preventing Explosions?" quest asks for a Security Upgrade, which keeps machines from exploding.^[6]
3. "Pressure from Liquids" quest and "Pressure from Heat" quest cover other pressure sources: the Liquid Compressor and the Thermal Compressor.^[6]
4. "The Pressure Chamber" quest needs Pressure Chamber Wall, Pressure Chamber Valve and Pressure Chamber Interface. It comes after Preventing Explosions? and Reinforced Stone, and the blocks asked for are enough for the 5x5x5 size.^[6]

Reinforced Stone also opens several tool quests. The Charging Station needs both Reinforced Stone and Moving Pressure, and under it sit the Manometer, the Pneumatic Wrench and the Camouflage Applicator. "Logistics" quest and the Reinforced Chest open straight from Reinforced Stone. The Minigun line runs from Minigun Ammo to the Minigun and then the Sentry Turret.^[6]

Oil and plastic

"Crude Oil" quest comes after the Pressure Chamber. The side quest after it covers drilling with a Gas Lift, Drill Pipe and Seismic Sensor. Heat comes next: "Heat Production" quest asks for a Vortex Tube, "Moving Heat" quest asks for Heat Pipe, and "Better Heat Production" quest asks for a Heat Sink.^[6]

"Oil Refinery" quest needs Crude Oil and Moving Heat. It asks for the Refinery Controller, Refinery Output and Thermal Lagging. The quest describes a 1x1x5 multiblock that produces Diesel, Kerosene, Gasoline and LPG, and each of those has its own quest: "Diesel" quest, "Kerosene" quest, "Gasoline" quest and "LPG" quest.^[6]

LPG leads to "Thermopneumatic Processing" quest and its Thermopneumatic Processing Plant, which makes Molten Plastic. That unlocks "Plastic" quest, "Yeast" quest and "Vegetable Oil" quest. The Yeast line goes on to "Ethanol" quest and "Biodeisel" quest, and Vegetable Oil leads to "Fish \& Chips!" quest. Diesel leads to "Lubricant" quest and the Diamond Drill Bit, then the Netherite Drill Bit.^[6]

Circuit boards

Plastic opens "Amadron" quest, "Capacitors" quest, "Transistors" quest, "Elevators" quest, the Pneumatic Jackhammer, the Pneumatic Door, the Reinforced Pressure Tube and the Empty PCB quest. The Amadron quest says you'll need to order stuff through it to continue. "PCB Blueprint" quest depends on both Amadron and the Empty PCB quest, and its text says it's on sale for 8 Emeralds.^[6]

1. "Charging with UVs" quest: the UV Light Box, which needs pressure and sunlight.^[6]
2. The Etching Tank and Etching Acid Bucket quests, which both follow the UV Light Box.^[6]
3. The Unassembled PCB quest, then the Finished PCB quest, which also needs Capacitors and Transistors.^[6]

Assembly and armor

The Finished PCB quest unlocks the assembly line pieces: Assembly Controller, Assembly IO Unit (import), Assembly IO Unit (export), Assembly Platform, Assembly Laser and Assembly Drill. It also unlocks "Pneumatic Armor" quest, Micromissiles and "Programming Drones" quest. The drones quest says it won't go over Drones, but suggests looking into them.^[6]

The Pneumatic Armor quest in turn opens a long run of upgrade quests, with the maximum count shown in each subtitle. These include the Block Tracker Upgrade, Entity Tracker Upgrade, Stomp Upgrade, SCUBA Upgrade, Elytra Upgrade and Charging Upgrade, which is listed as max 6.^[6]

All the Mods 10: To the Sky 1.2.1 ships PneumaticCraft: Repressurized 8.2.13. The mod has been in the pack since 1.0 or earlier. I don't have pack changelog entries for this mod, so what follows comes from the mod's own 8.2.13 changelog.^[2]

Added in 8.2.13

• The max height Jet Boots can reach before cutting out is now configurable. It used to be fixed at world build height + 64. The option is jet_boots_height_limit in the common config.^[30]

Changed in 8.2.13

• All PneumaticCraft fuel fluids now sit directly in the c:<fluid> fluid tag instead of c:fuels/<fluid>. This is more in line with other mods, so check any tag-based setups you have.^[30]
• Json syntax errors in the aux config files (the files in config/pneumaticcraft/*.cfg) no longer stop the game from starting. An error is logged and that subsystem starts with default settings.^[30]

Fixed in 8.2.13

• Elevator caller screens have a better button layout algorithm, especially when there are many floors.^[30]
• The "Limit Interaction" setting on the Drone Entity Attack widget should now work correctly when the drone uses a Minigun or Micromissiles.^[30]
• The Pneumatic Chestplate now honours the Apotheosis Elytra affix, so Elytra flying is allowed with the affix even without the Elytra upgrade installed.^[30]
• Pressure Chamber Valves no longer wrongly report a 0x0x0 chamber size in some situations.^[30]
• The Void Liquid widget no longer makes drones hang when no filter is in use and the drone has an empty tank.^[30]
• Omnihopper and Liquid Hopper block shapes are now correct with certain hopper rotations.^[30]
• Pneumatic Armor hotkeys now update correctly if you change them in the vanilla keybinding screen.^[30]
• Pistons now overwrite PneumaticCraft fluids instead of pushing them.^[30]
• Crash fixes: the Pneumatic Door renderer in some situations, and unselecting all sides of a sided programming widget. Some client-side memory leaks were also fixed.^[30]
