Crafter's Ledger

Compact hopper automation for Minecraft 1.21.1. Crafter's Ledger adds an Artisan Crafter and reusable Copper Pattern Stencils that reserve each ingredient's place in a nine-slot recipe.

Features

• Imprint patterns from real ingredients or configure ghost items with Shift-clicks.
• Single-Batch mode accepts one item per matching slot; Balanced Buffer mode distributes matching ingredients evenly, with a default cap of 16 per slot.
• Craft automatically every 8 ticks, or use redstone pulses with a 4-tick crafting delay.
• Send crafted results and buckets or bottles into the container in front. Overflow drops as items.
• Read recipe readiness with a comparator.
• Copy imprinted stencils in a crafting grid. Sneak-use a water cauldron or grindstone to clear a stencil.
• Includes survival recipes, recipe unlocks, persistent settings, and configurable timing and buffer limits.

Getting started

Craft Copper Pattern Stencils with copper ingots, paper, and honeycomb. Craft an Artisan Crafter with a vanilla Crafter, copper ingots, a comparator, redstone, and polished deepslate. Place a blank stencil in its stencil slot, arrange a recipe in the grid, and click Imprint Pattern. Place a hopper above and a barrel in front, then feed the ingredients. Auto-Batch mode crafts complete recipes automatically.

Requirements

Minecraft 1.21.1, Fabric Loader 0.16.14 or newer, Fabric API 0.116.6+1.21.1, and Java 21 or newer. Install the mod and Fabric API on both client and server. This download is for Fabric.

Verification

All 18 packaged-JAR GameTests passed, including hopper distribution, mixed ingredients, item conservation, crafting remainders, stencil copying and clearing, persistence, and server packet validation. Normal Gradle execution and graphical client acceptance were blocked in the build environment; live multiplayer remains untested.
