Ex Mekanism Deorum
An addon that reimagines Ex Deorum machines (Hammer, Sieve, Barrel, and Crucible) as Mekanism machines. Automate all your Ex Deorum processing with FE power, upgrades, and full side configuration support.

Overview
Ex Deorum's manual and mechanical machines are re-implemented using Mekanism's machine architecture. Because recipes are directly referenced from Ex Deorum at runtime, custom recipes added via datapacks work out of the box.
- 25 Blocks: 5 Base Machines + 20 Tiered Factories (Basic / Advanced / Elite / Ultimate)
- Full Mekanism integration: Upgrades (Speed, Energy, Muffling), Side Configuration, Security, and Redstone control
- Factory parallelism: 3 / 5 / 7 / 9 parallel lanes for Basic, Advanced, Elite, and Ultimate (Crucibles scale melting speed by 5x / 10x / 20x / 30x instead)
- Compressed Hammer support: inserting a compressed hammer enables
compressed_hammerrecipes automatically - JEI integration: registered as catalysts for Ex Deorum categories; click the GUI progress bar to jump directly to recipes
Requirements
| Requirement | Version |
|---|---|
| Minecraft | 1.21.1 |
| NeoForge | 21.1.265 or higher |
| Ex Deorum | 3.12 or higher (Required) |
| Mekanism | 10.7.19 or higher (Required) |
| JEI | Optional |
Install on both client and server. No configuration file needed.
Installation
- Set up a Minecraft 1.21.1 environment with NeoForge (>= 21.1.265).
- Place Ex Deorum and Mekanism into your
mods/directory. - Place this mod's jar file into your
mods/directory.
Machines & Factories
| Family | Base Machine | Tiered Factories | Base Consumption |
|---|---|---|---|
| Hammer | Hammer Machine | Basic – Ultimate Hammer Factory | 20 FE/t |
| Sieve | Sieve Machine | Basic – Ultimate Sieve Factory | 40 FE/t |
| Barrel | Barrel Machine | Basic – Ultimate Barrel Factory | 10 FE/t |
| Lava Crucible | Crucible Machine | Basic – Ultimate Crucible Factory | 20 FE/t × melt multiplier |
| Water Crucible | Water Crucible Machine | Basic – Ultimate Water Crucible Factory | 20 FE/t × melt multiplier |
Crucible factories do not use parallel lanes; instead, their melting speed scales by 5x (Basic) / 10x (Advanced) / 20x (Elite) / 30x (Ultimate) with matching energy consumption (energy per mB produced remains constant).
Machine Details
Hammer & Sieve
- Hammer Machine: Requires a hammer in the auxiliary slot (slot 22). Durability is consumed per operation. Supports Efficiency and Fortune enchantments. Output distributes into 20 output slots.
- Inserting a compressed hammer (
#exdeorum:compressed_hammers) enables processing compressed blocks viacompressed_hammerrecipes.
- Inserting a compressed hammer (
- Sieve Machine: Requires a mesh in the auxiliary slot (slot 22). Mesh Efficiency and Fortune enchantments apply. Hand-only recipes are ignored mechanically.
- Item Consumption: Input items remain in their slot while processing and are only consumed by 1 upon operation completion.
Barrel
- Features 2 item input slots, 1 item output slot, and dedicated fluid input & output tanks (1,000 mB × parallel lane count each).
- Supports composting, item + fluid mixing, in-world fluid mixing (fluid block above), catalyst transformation (3×3 blocks below), and rainwater filling.
- Composting: Added biomass fills the compost buffer instantly; the progress bar tracks compost fill percentage, then switches to the dirt creation phase.
- Fluid inputs only accept external filling when the barrel is idle (compost buffer is 0 and item inputs are empty).
Crucible
- Lava Crucible: Melts solid items one by one into fluid. Melting speed depends on the heat value of the block directly underneath (
crucible_heat_source). Without a heat source, no energy or items are consumed. - Water Crucible: Dedicated to
water_cruciblerecipes. Requires no heat source (fixed base rate). - Fluid outputs can only be extracted via fluid pipes (no manual bucket insertion into the output tank).

Crafting Recipes
Base machines use the standard Mekanism machine ring: ACA / IPI / ACA (A = Redstone, C = Basic Control Circuit, I = Iron Ingot), surrounding the corresponding Ex Deorum mechanical part P:
| Machine | Center Part P |
|---|---|
| Hammer Machine | exdeorum:mechanical_hammer |
| Sieve Machine | exdeorum:mechanical_sieve |
| Barrel Machine | exdeorum:oak_barrel |
| Lava Crucible | exdeorum:porcelain_crucible (+ Lava Bucket at bottom center) |
| Water Crucible | exdeorum:porcelain_crucible (+ Water Bucket at bottom center) |
Tiered factories follow Mekanism's tier upgrade progression (Basic -> Advanced -> Elite -> Ultimate), crafting directly from the previous tier block.
Known Limitations
- Textures and GUIs are currently placeholder assets (open for customization and tuning).
compressed_sieverecipes are not automated (compressed hammer recipes are supported).- Barrels taking fire damage from hot fluids is not implemented.
