Surge Alloy Smelter for core

Place the left edge in contact with core vaults. It will withdraw the necessary resources directly from core storage and then deposit surge alloy into the core.

Uses logic to dynamically configure unloaders for a smaller footprint, while maintaining constant uptime. Monitors core resources and automatically shuts off when resources are depleted below a configurable limit. Includes on/off switch.

Schematic code:

The unloaders near the core use both the silicon and copper unloaders to feed titanium as needed, maintaining a silicon:copper:titanium ratio of 3:3:2.

For best performance, each unloader needs a dedicated config instruction because Mindustry applies a timeout to each config instruction to prevent packet spam.[github.com]

Edit the auto-shutoff limit on the first line.


This design uses the logic from the 6 smelter design, modified for 4 smelters.


This logic load balances titanium feeding across all 3 unloaders, with 2 dedicated configure instructions per for rapid switching, to sustain sufficient throughput for constant uptime while overdriven. Does not monitor core resources.


Compact design for ammo production for Cyclones/Foreshadows. Buffers excess surge in the same vault used to buffer inputs.

Feed inputs into the sorters on the left, but don't put lead in the lead sorter. It is set to lead to block the lead unloader next to it from backfeeding.
