2D 1728 Furnace Array (622.08k/h)

An advanced 2-dimensional box input 1728 furnace array designed for Minecraft 1.19 and newer versions. This massive smelting installation delivers a rate of 622.08k items per hour across its 1728 Furnace units while preserving shulker boxes so that smelted items return to the exact box they arrived in.

How It Works

• Built with a multidimensional layout utilizing an Overworld and Nether connection, featuring locked Hopper carts to decrease lag and a centralized cart yeeting location to reduce build effort.
• Includes a fuel level indicator that lights up one lamp for each double chest of shulker boxes of fuel in storage, with the first lamp activating after half a double chest.
• Safety mechanisms pause the smelter if loose items, partial boxes, or unsmeltable items are placed in the input, routing them to designated Barrel blocks, as well as pausing when the output is full or fuel drops below 1.5 double chests.

What It Produces

• Smelted items at a rate of 622.08k/h using 1728 furnaces.

How to Use

1. Input shulker boxes of smeltable items into the labeled chest.
2. Input shulker boxes of fuel into the labeled chest. Note that only blaze rods and coal are valid fuel sources.
3. Hit the Note Block to start the furnace array.
4. Retrieve your smelted items from the output, remembering to wait until the chest minecart leaves its station before leaving the area.

Before you build

• Replace detector rails or update detector rails with a debug stick after pasting the schematic.
• This design is directional and must not be rotated.
• Player must wait until the chest minecart goes to the Overworld before leaving the area.
