If you're an experienced Endfield player tired of manual grinding, it's time to build a fully passive mining-to-refining pipeline. The goal is simple: ore goes in, refined materials come out, and you never have to touch a thing. This guide walks you through a compact, belt-savvy setup that nearly doubles throughput compared to default blueprints and frees your playtime for exploration and boss fights.

Ditch the Portable Rig Early

Portable Originium Rigs (Mining I) look convenient because they require no power, but they're a trap. They fill fast, halt production when full, and require manual collection. Worst of all, they have no auto-delivery — ores sit on-site with no routing to your base. As soon as you unlock Electric Mining Rigs (Mining II in the AIC Plan tech tree), dismantle every portable rig you have. They're tutorial bait, not farming tools.

Electric Rigs: Your Passive Income MVP

Electric Mining Rigs cover a 3×3 area, draw 5 power each, and mine continuously. They auto‑route ores directly to your AIC Depot with zero interaction. Place one on every ore node you can reach — Originium, Amethyst, Ferrium — because an unused node is lost material you'll need for high‑tier gear, explosives, and Stock Bills.

Power Chain: Keep It Simple

You already know the architecture: PAC or Sub‑PAC → Relay Towers (chain for distance, using line‑of‑sight) → Electric Pylons (wireless coverage for multiple rigs). Place pylons on high ground when possible, and unlock Power I in the AIC tree early for more capacity. One pylon routinely powers 3‑5 rigs. For outposts, Sub‑PACs handle local grids; run relays into dangerous zones without dropping pylons there.

From Depot to Refinery: The Compact Belt Path

Electric rigs beam ore straight to your Depot, so you don't need overworld belts at the mining site. At your base, the Depot unloads onto belts. Those belts feed Refining Units (3×3, 5 power), and refined materials move to storage or crafters. You unlock belts, splitters, and convergers via the VR Simulator Logistics tree.

Critical rule: Feed each Refining Unit with a single input lane. Multiple input lanes cause jams and halve effective throughput because the unit processes at a fixed speed regardless. Always use one input, one output, and match the arrow directions. Leave a 1‑block gap between units so you can slot an Electric Pylon in the center — that pylon powers the unit, its belts, and neighboring units.

Ditch Tutorial Blueprints, Build Compact

Default blueprints from Simulations use long belts, excessive turns, and splits that cause slowdowns and stalls. Replace them with compact layouts:

• Place a unit one block from its storage (e.g., a Gearing Unit next to a refined mats stash).
• Run a straight belt from storage output to unit input — no turns.
• Feed the unit's output onto a central collection belt.
• Set the recipe (e.g., Amethyst Components) and you're done.

This approach runs at least twice as fast as default layouts. Use the Depot Bus (unlocked from the AIC Steward quest) for additional ports if you need more material flow.

Scaling: Parallel Lines and Centralized Processing

When demand for T3/T4 materials spikes, scale by adding parallel lines. Keep your setup dense:

• Group the core processing chain (Shredding → Moulding → Filling → Packaging → Gearing) with short belts and central power.
• For planting, loop extra seeds via Stashes to get infinite crops.
• Use splitters to balance outputs across multiple parallel units.

Centralize storage and refiners so materials flow from ore → components → packaged goods without backtracking. A single central pylon in the gap powers the whole cluster, eliminating wasted space and belt length.

Why Bother?

A fully passive pipeline lets you stockpile massive quantities for outposts (which earn Convention Certificates and pulls), handle endless Stock Bills, and breeze through later chapters. You spend your time exploring or fighting, not running back and forth. Once you build this, you'll never go back to manual mining.
