Smart Shulker Unloader

Smart Shulker Unloader

Automatic shulker unloading. Keep your items moving.

Smart Shulker Unloader adds an always-on machine that empties supported shulker boxes into a compact item buffer. Feed it from a hopper, let it unload, and collect the empty box separately—no redstone control required.

⚙️ Features

• Automatic operation: Starts when a supported filled shulker box is inserted.

• Hopper input: Feed shulkers from above or place one in the machine’s GUI.

• Nine-slot item buffer: Unloaded items are stored in the machine and can be extracted from below.

• Separate empty-box return: Empty shulkers are returned from the rear side of the block.

• Safe output handling: Unloading pauses when the item buffer is full and resumes when space becomes available. Remaining contents stay inside the shulker.

• Whole-box progress: The GUI tracks progress across the complete unloading job.

• Vanilla and Ascended Storage support: Works with vanilla shulkers and compatible Ascended Storage shulkers.

• English and German interface: GUI text follows the selected game language.

🔨 Crafting the Smart Shulker Unloader

Craft the machine in a regular crafting table:

🧩 Using the Unloader

Place the block with its front facing the side you want to access. Insert a filled shulker box through the GUI or feed it with a hopper above.

The machine moves the shulker’s contents into its nine-slot buffer. A hopper underneath can extract those items. When the shulker is empty, the machine moves it to its separate return output at the rear. Place a hopper behind the block to collect empty boxes automatically.

If the item buffer is full, the machine waits without discarding the remaining contents. It resumes automatically when a hopper removes items. If the empty-box return output is occupied, the machine waits until it can return the box.
