CrafterLock is a lightweight Minecraft plugin designed to make automated crafting with Crafters easier, cleaner, and more reliable.

Normally, automated Crafter systems can require additional redstone and carefully controlled item distribution to prevent ingredients from disappearing or recipes from becoming disrupted. CrafterLock simplifies this by allowing you to lock a recipe directly inside a Crafter.

Simply arrange the ingredients in the Crafter exactly how you want them, look at the Crafter, and use /crafterlock.

CrafterLock will remember the configured recipe slots and keep one item reserved in each locked slot. These reserved items act as a permanent recipe template and will not be consumed during automatic crafting.

For example:

Iron	Iron	Iron
Empty	Stick	Empty
Empty	Stick	Empty

Once locked, the Crafter can continue receiving ingredients and crafting automatically, while the final Iron and Stick in each configured slot remain protected.

Perfect Together with HopperLock

CrafterLock works especially well alongside HopperLock. HopperLock can control and filter the ingredients being supplied, while CrafterLock keeps the recipe itself protected inside the Crafter.

Together, they allow you to create compact automated crafting systems without building huge redstone sorting and recipe-management contraptions.

Set the recipe. Lock it. Feed it. Craft automatically.
