THANKS EVERYONE FOR THE 2,000 DOWNLOADS !!
You have no idea how happy it makes me to see so many people trying out my mod. Don't hesitate to give me feedback so we can improve it together.
An independent, unofficial addon for Mekanism. Not affiliated with, endorsed by, or maintained by the Mekanism team.
Mekanism: Engineering adds endgame mining, quantum networks, teleportation, large-scale fluid and rock production, and tools to run a factory with precision. The cards use in-game item renders and recipes; where a feature has a screen, they show its real in-game interface.

The centrepiece reaches a radius of up to 128 blocks and mines at 4× the standard Digital Miner's base speed with default settings. It can draw energy from a Quantum Entangloporter frequency without a cable. QIO can receive mined items and supply replacement blocks; local storage and quantum item frequencies work too. The Companion can relocate it to the next site, by hand or automatically.

The Companion puts status, filters and controls in your hand. It also watches and drives Mekanism's standard Digital Miner; relocation is for the Quantum Digital Miner only. Remote actions respect permissions and need the miner's chunk to be loaded.

A 4-pixel plate fixed on any face of a machine, like a layer of snow: it takes energy from a Quantum Entangloporter frequency and gives it to that machine, up to the output of the Energy Cube of its tier. It receives energy only. Craft it up from Basic to Ultimate: it keeps its frequency, faces and redstone mode.

Everything a Quantum Entangloporter carries, plus a shielded channel for radioactive chemicals such as Spent Nuclear Waste. While its frequency holds any, it cannot be broken, blown up, or have its frequency deleted. Its "Confinement" panel shows how much it holds, whether the radiation is contained or locked until emptied, and what it holds.

A read-only screen for your frequencies: every Entangloporter and Receiver, where it is, its rate and its share of what goes in or out, the net balance and its last minute. A "≈" marks a rate that is an estimate. Click a device to make it glow through walls until you right-click it.

The Quantum Portable Teleporter jumps to one of your Mekanism Teleporters, checked coordinates, or a random safe place. It shows the destination before charging: a refused jump costs nothing. The 1 GJ battery pays 1%, 50% or 25% respectively; jumps are free in Creative mode.

The Quantum Chargepad charges energy items in your armour, off-hand, hotbar, inventory and Curios slots together. It stores 1 GJ and can supply 256 MJ/t per player; armour gets priority when power is limited.

The 3 × 3 × 3 station connects to Mechanical Pipes, so the pump itself can stay beside your installation. Its pipe intake must be immersed in the liquid to start. A Filter Upgrade makes heavy water. Its screen always says why it is not pumping: no intake, no source, a shared or oversized pipe network, an unloaded area.

For the Quantum Fluid Pump: eligible sources, lava included, stay in place while it pumps, at an additional energy cost.

Water, lava and energy make one selected rock at a time: pick it in one click from a row of products, and the chosen one shows on the machine's roof. Use it for a dedicated material.

The multiblock runs eight independently configured rock lines. Feed it water, lava and energy, or fit its modules. Its water and lava towers are empty at 0 mB and full from the first millibucket, and its screen shows the reason it stops and which line is waiting.

The two Plant modules make its water and its lava from energy alone.

Split items between output faces in equal or weighted shares, down to precise item counts: keep a recipe's ingredients in proportion, or give a busier line a larger share. Wait for every output holds a batch until every output can take its full share.


One shared vault of upgrades for the machines around it: scan, pick an upgrade, set a number (or Max) for each type of machine, and apply. Apply and Set all machines to max act on the upgrade you are looking at only, so applying Speed never moves your Energy Upgrades. Each row shows the real block of the machine and how many were found. Upgrades an Apply would take out are shown in red before you press it; Remove a stack puts a stack back in your inventory. With Mekanism Extras, its extra upgrades open from a drop-down list. Its zone is a server setting, shown with Mekanism's Visuals tab.
All three are optional; the addon runs without them.
Interfaces are in-game screenshots; item images are the game's own renders; recipes follow the mod's data (a tagged ingredient shows one valid item).
Client and Server: install the addon and Mekanism on both. Version 1.1.0 needs Minecraft 1.21.1, Java 21 and NeoForge 21.1.200 or later in the 21.1 series. Its JAR accepts Mekanism from 10.7.15 up to, but not including, 10.7.20. Generators, Tools and Additions are optional, and so are JEI, Jade and WTHIT. English and French translations are included.
Version 1.1.0 passed its unit, in-world and dedicated-server tests with each of the five stable Mekanism builds from 10.7.15.81 through 10.7.19.85, and its client-screen tests with 10.7.19.85 (with JEI, Jade and WTHIT loaded too). A copy of an All the Mods 10 world was moved from 1.0.2 to 1.1.0 and played; the pack's own JEI (19.25) works with it. Worlds from 1.0.2 open unchanged; the Precision Upgrade Controller's old "max" settings are carried over.
mekanismengineering-server.toml provides 77 server settings for energy, storage, ranges, fluid rates and processing limits. Crafting and rock-production recipes can be changed with datapacks. Mekanism's own settings remain in its configuration files. The player guides explain every block and setting.
