About this Mod
Mekanism isn’t simply another add-on. Mekanism is an experience that will forever change the way you play Minecraft.
Here at Mekanism, Inc., we bring you a suite of low, mid, and high tier machinery to elevate your archaic home and inefficient resource processing to the 21st century. With our collection of high-tech tools, high-end energy generators, advanced transmission systems and intricate processing mechanisms, you’ll find yourself relieved of the tedious tasks of ‘mining’ and ‘crafting’ and quickly progressing to new levels of technological enlightenment.
You may not realize it, but every time you smelt an ore directly into its respective ingot, you’re wasting the majority of what you’ve mined. Mekanism’s team of experienced chemical and mechanical engineers have developed advanced ore processing machinery to extract resources from ores with utmost efficiency. With our purification, dissolution, chemical injection, and crystallization technologies, you can now double, triple, quadruple, even quintuple your ingot production per ore, given enough infrastructure and energy.
Our engineering team understands and embraces gradual technological progression. For whatever stage of gameplay you’ve reached, we offer a tier of machinery to suit your needs. Every Mekanism machine can be upgraded to a factory, allowing you to process, 3 (basic), 5 (advanced), 7 (elite), or even 9 (ultimate) different items at once -- in a single machine! No more are the rows, even walls of slow and ugly furnaces that once plagued your home. Condense your machinery infrastructure with Mekanism today.
Just a few of the many reasons Mekanism will be the highlight of your Minecraft experience:
- Hydrogen-powered Jetpacks, with multiple togglable flight modes
- A small, cute, and loyal robotic friend (Robit!) to follow you around
- A Digital Miner with state-of-the-art filtering technologies to automate your mining needs
- A Fusion Reactor which uses advanced internal confinement technology to harness the power of the sun to run advanced machinery (requires Mekanism Generators)
- Various transmitters for transferring items, fluids, gases, energy, and even heat!
- An effective machinery configuration system, which allows for the creation of advanced item transport networks capable of sorting and filtering (using our patented Logistical Transporters!)

Mekanism Digital Miner causing server lag – solution?
The Digital Miner loads chunks in its scan radius and checks every block – extremely CPU intensive. Fixes: 1) Limit scan radius to 32 max (mekanism-server.toml → digitalMinerMaxRadius). 2) Allow only one Digital Miner per player. 3) Alternative: pre-generate chunks with Chunky so the miner doesn't need to load new chunks.
Mekanism Radiation crashing the server – how to disable?
Radiation crashes occur when many contaminated chunks are loaded simultaneously. To disable radiation: mekanism-server.toml → radiation.enabled=false. For a moderate fix: lower radiationIntensityPerSBq and reduce maxRadiationRadius. With Mado Hosting: edit config files directly in the file manager.
Mekanism server crashes on startup – what to do?
Most common cause: wrong forge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 4 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.
Known Issues & Server Tips
- ⚠Turbines at maximum height (18 blocks) can slow server ticks with high steam production.
- ⚠Fission Reactor meltdowns can permanently burden surrounding chunks – regular backups recommended.
Server Configuration
Optimal config: mekanism-server.toml → digitalMinerMaxRadius=32, radiation.enabled=false (for beginners), maxPathFuelTank=60000. With 5+ players: at least 6 GB RAM.
