Uncrafting Table

The Uncrafting Table takes a crafted item apart and gives you back the ingredients of one of its recipes.

Uncrafting Table

Any type of planks works. This recipe is used from v1.8.2; older versions use a different recipe.

The screen

• Input slot. The item to take apart. A colored overlay means it can't be uncrafted right now; hover it to see the reason.
• Output slots. Where the ingredients go. With autoMoveToInventory on (the default), they are moved straight to your inventory.
• UnCraft button. Uncrafts once. Shift + click repeats until the input or your experience runs out.
• Experience cost. The bottle beside the button shows what one uncraft costs. Hover it to see whether that is levels or points.
• Recipe list. Shown on the left when the item has recipes. Pick the one to reverse and use the < and > buttons to page through them.
• ? icon. Hover it to see the config commands.

Output slots take stacks of the same item, so ingredients are stacked together rather than laid out in the crafting shape.

Why an item can't be uncrafted

Each reason has its own overlay color, which you can change in the client config.

Tooltip	What to do
No Recipe Found!	The item has no crafting or smithing recipe the table can reverse, or every recipe is excluded by the config.
No Suitable Output Slot!	Empty the output slots.
Not Enough Experience!	Gain more levels or points. See the experience settings.
Not Enough Input Item!	The recipe makes more than one item, so put at least that many in the slot.
Shulker Box is Not Empty!	Empty the shulker box first.
Item Restricted by Config!	The item is on the server's restriction list.
Item is Damaged!	Repair the item, or see the damaged item settings.
Enchanted Item Not Allowed!	Disenchant the item, or see allowEnchantedItems.
Quest Not Completed!	Finish the FTB Quests quest or chapter the item is locked behind.
Item Not Defined in Progression!	Only items listed in the progression config can be uncrafted on this server.

Damaged and enchanted items

• Damaged items give back fewer of their repair material, in proportion to the durability lost. Items with no repair material (bows, shears, fishing rods) are refused unless allowDamagedNonRepairable is on.
• Enchanted items can be uncrafted while allowEnchantedItems is on. With outputEnchantedBook on, you also get an Enchanted Book with the item's enchantments.
• Smithing upgrades such as netherite gear and trimmed armor can be uncrafted while allowUnSmithing is on.

Sophisticated Backpacks

Backpacks and standalone upgrades support their crafting and tier-upgrade recipes, including netherite smithing upgrades. The same compatibility adapter is included in the Fabric and NeoForge builds; a compatible Sophisticated Backpacks release is required for your Minecraft version and loader.

Reversing a backpack tier upgrade returns the lower-tier backpack with the same storage identity, contents, installed upgrades, name and colors, plus the upgrade materials. The lower tier uses its own inventory and upgrade capacity. Move items out of inventory slots and upgrade slots that the lower tier cannot hold before uncrafting; the table does not move or delete those contents automatically.

Fully dismantling a basic backpack requires an empty inventory and no installed upgrades. Unlink linked storage first. Backpacks with unopened loot are also protected. Configured standalone upgrades pass their data to the predecessor upgrade; dismantling an upgrade with stored state into an inert upgrade base is blocked. The Contents cannot be preserved tooltip indicates these protections.

These checks apply to both manual and automatic tables, including a final check if stored contents changed after the recipe preview was created.

Automation

Hoppers and pipes can feed the table and empty it.

Side	What it exposes
Top and sides	The input slot, insert only
Bottom	The output slots, extract only

The Uncrafting Table still needs a player to click UnCraft. For hands-free uncrafting, use the Auto Uncrafting Table.

Config commands

Command	Opens	Who can use it
/ueconfig client	Client config	Everyone
/ueconfig common	Common config	Creative mode or operators
/ueconfig exp	Per item exp config	Creative mode or operators
/ueconfig progression	FTB Quests progression config	Creative mode or operators, with FTB Quests installed

Limitation

An item doesn't remember what it was made from. A Crafting Table made from birch planks is the same item as one made from oak, so the table can't know which planks were used. Instead, the recipe list offers one entry per plank type (as in the screenshot above) and you choose what you get back.

Turn on restrictAmbiguouslyCraftedItems to block these recipes entirely.
