Choose your task: learn IC2 Classic, troubleshoot a machine, install the mod or join the Industrial server.

IC2 Basics

Understand the mod and begin with correct 1.19.2 references.

EU Energy

Power generation, storage and safe machine connections.

Machines

Run and troubleshoot one machine at a time.

Automation

Scale a tested factory with item and fluid movement.

Ore Processing

Follow actual input/output recipes instead of assuming fixed yields.

Nuclear Power

Confirm heat, cooling and component version before experimentation.

Reactor safety

Installation

Standalone Forge installation and KRAYMO launcher are different goals.

Minecraft Industrial Servers

Explore multiplayer availability and server features.

Where to start with IC2 Classic

Start with a generator and one compatible low-voltage machine. Confirm that the fuel produces EU and that the receiving machine is powered. Then add a BatBox and verify its output orientation.

Next introduce the Macerator, Electric Furnace and longer cable runs. When something stops working, go back to a small test circuit and check one component at a time.
