The Generator turns fuel into EU for your first machines.

A fuel-burning EU source for a starter workshop. It converts compatible fuel into EU; it does not process ore or act as a transformer.
What it does and how it works
The older developer wiki documents solid fuel operation and the historical figures 10 EU/t with a 4,000 EU buffer. Those are legacy figures: neither one has been measured in the installed KRAYMO 1.19.2 client.
Materials and prerequisites
Generator (use the installed crafting recipe), accepted solid fuel such as coal, one low-tier electric machine, and an optional suitably rated cable or BatBox.
These are prerequisite categories, not a guaranteed crafting grid. Confirm exact item counts in the installed 1.19 recipe viewer.
Step-by-step setup
- Place one Generator close to a Macerator, without mixing power tiers.
- Put supported fuel in the Generator and confirm its GUI reports available EU.
- Run a known supported item recipe on the connected machine.
- Only after success, extend the network with correctly oriented storage and cables.
Example setup or workflow
Conceptual flow, not a real-game screenshot or an assertion about exact block faces.
Processing your first ore? Fuel the Generator, test the Macerator with one valid ore, then verify the actual dust output. Add the BatBox later to test whether stored EU can keep the same recipe running after fuel is exhausted.
Common problems and troubleshooting
| Symptom | Test or remedy |
|---|---|
| Fuel burns but the machine stays idle | Check EU output, cable continuity and valid machine input. |
| Generator appears empty | Confirm the fuel type is supported in the current edition. |
| Network breaks after adding storage | Check BatBox output orientation and energy tiers. |
EU data, recipes and version compatibility
| Item | Source / confidence |
|---|---|
| Minecraft + Forge | IC2 Classic has an official Forge 1.19.2 release; KRAYMO targets Minecraft 1.19.2 with Forge 43.5.2. |
| 1.19 recipe information | Developer directs 1.19 players to the in-game Wiki Book; datapacks can customize machine recipes. |
| KRAYMO mod jar and precise EU specifications | Not independently verified in this article. Confirm against the installed client and server configuration. |
| Crafting-grid ingredients and item counts | Use the installed recipe viewer; old 1.12 tables are not presumed accurate. |
Edition-specific note: Legacy technical reference only: 10 EU/t output and 4,000 EU internal buffer. Treat as unverified for IC2 Classic 1.19.2.
