⚙️ Mega Super Smelter — 115,200 Items/Hour | 1,800 Stacks/Hour
After weeks of engineering, redstone designing and problem solving, I finally completed my fully automatic mega super smelter — one of the most complex machines I've ever built in Minecraft.
📊 Performance Stats
🔥 360 furnaces running simultaneously
⚡ 115,200 items/hour output
📦 1,800 stacks/hour throughput
🚀 Runs smoothly even on an Aternos server with minimal lag
🔧 How It Works
The machine runs on two separate input systems. The first is a direct chest input where you manually load items — a hopper minecart instantly picks up 5 stacks, distributes them across all furnaces and returns automatically. The second is a full shulker box pipeline powered by the 2 Million HopperCart Yeeter unloader designed by CubicMetre, one of the fastest shulker unloaders ever built in Minecraft.
Output is automatically packed into shulker boxes by 2 custom-designed shulker loaders running at 3x hopper speed. The standout feature of my loader is its half-filled shulker auto-eject system — when items stop flowing, it automatically dispenses the partially filled shulker so nothing gets stuck inside. Players never need to manually intervene.
🛡️ Safety & Automation
What makes this build truly special is its extreme safety system:
🔴 Visual clogging indicator lamps — instantly shows which part is clogged and why the system stopped
🔒 Dual lever safety locks — prevents accidental activation mid-run
📋 Labelled control panel with clear instructions for every mode
🧲 Automatic fuel system — no manual coal needed
⚠️ Duper manual mode for maintenance
📦 Separate output chests for filled shulkers, half-filled shulkers and extra overflow items
⚠️ One Rule Only
Do NOT drop unstackable or unsmeltable items into the input chest. A single wrong item will clog a furnace and collapse the whole system — forcing you to manually check all 360 furnaces one by one. Read all the instructions carefully so you don't need to worry and hopeless when machine stop.
🏗️ Scale
From the aerial view alone you can see the sheer size of this machine — tiered furnace rows, minecart rail networks, shulker loading bays, redstone control rooms and a dedicated output collection area all working together in perfect sync.
Built entirely in survival. Zero compromises on safety or efficiency.If anyone found any kind a problem facing this mechanism please let me know in comment section. Thank you and Enjoy 😊

1. See the activator rail is collide behind the block, is that rail is in simple straight line that would be a issue.
2. Common mistakes some of redstone dust, torch or comporators missing at that place, please check by placing litematica.
Please follow these step if it works --
1. Please place the litematica again using litmatica mod and check if any redstone dust or redstone component is missing or not.
2. Place the schematic in testing world and check the hoppers cause there are some items in hopper for running the unloader.
3. Or search in YouTube "4M hoppercart yeeter by cubicmetre" if this video help you.
NOTE : Few chest, barrels, hoppers are containing items for running the farm. Please check before turn on the farm.
What is Extra item container (Barrel) ?
That is a barrel or chest which contains extra items like which are not smelt by mistake or items are wrongly put.
I will help you if you can explain more ( Thank you )
Step by Step Guide -
1. If it was still blocked after pulling the lever that means you already use the machine once and auto refueling system started. After refueling all the furnaces the machine auto turn on. Just wait some time when the refueling lamp goes to turn off.
2. If you pull 2 levers at a same time. The safty system activated. Turn on one lever the interact.
3. If doesn't work anything place the litematica again and follow step by step where is the missing redstone dust, component or something wrong.
4. Place the schematic model on another world and test it. Because some barrels and Hoppers contain items, if the items are not there the machine will stop working. In litematica the chests, shulker boxes, barrels, hoppers are place as well but if the container contains some items that will be paste as it is with world edit.
