Simple Cobblestone Generator

Cobblestone Generator in the world

Simple Cobblestone Generator adds a single block that provides an endless supply of cobblestone for automation. Generation is free and unlimited by default, or it can be configured to consume energy and limit each extraction.

Fabric 26.2

The Minecraft 26.2 release is a Fabric port of the original mod. It runs on both the client and server and requires:

Minecraft 26.2
Fabric Loader 0.19.3 or newer
Fabric API
Java 25

Team Reborn Energy API support is bundled in the mod JAR, so it does not need to be installed separately. Older downloads remain available for their original Forge versions.

Features

Extract cobblestone from any side with Fabric Transfer API-compatible pipes and storage systems.
Insert cobblestone from any side. As in the original mod, each insertion accepts and voids one cobblestone.
Optionally require energy for every extracted block.
Persist stored energy across world saves.
Limit the amount returned by each automation extraction.
Inspect, change, or reload the server configuration while the game is running.

Crafting Recipe

The Cobblestone Generator uses the original recipe:

Configuration

The first launch creates config/simplecobblegen.json:

{ "rf_per_block": 0, "max_cobble_per_tick": -1 }

rf_per_block: energy required for each generated cobblestone. 0 disables energy use.
max_cobble_per_tick: maximum blocks returned by one automation extraction. -1 is unlimited and 0 disables generation.

Server administrators can manage these settings without restarting:

/simplecobblegen config /simplecobblegen config get /simplecobblegen config set rf_per_block <0 or greater> /simplecobblegen config set max_cobble_per_tick <-1 or greater> /simplecobblegen config reload

Command changes are saved and become active immediately. Use reload after editing the JSON file directly. Invalid files are rejected without replacing the active settings.
