About Configurable Core Miner Returns

From Factorio Mod Portal

Configure diminishing returns for Space Exploration core miners in Factorio 2.1.22+. Adjust the efficiency penalty per additional miner from 0-100% via map settings.

Configurable Core Miner Returns

A Factorio mod that allows you to configure the diminishing returns rate for Space Exploration core miners. Versions 2.1.x support Factorio 2.1.22+ and Space Exploration 0.7.63+.

Features

  • Adjustable diminishing returns rate (0-100%)
  • Default 10% diminishing returns per additional miner

How It Works

Each core miner after the first contributes slightly less than the previous one, based on the configured rate.

With the default 10% setting:

| Miners | Marginal Efficiency | Average Efficiency | |--------|--------------------|--------------------| | 1 | 100% | 100% | | 2 | 90% | 95% | | 3 | 81% | 90.3% | | 4 | 72.9% | 86.0% | | 5 | 65.6% | 81.9% | | 10 | 38.7% | 65.1% | | 20 | 13.5% | 43.9% |

  • Marginal Efficiency: The efficiency of the last miner placed
  • Average Efficiency: The displayed per-miner yield (total output ÷ miner count)

The configured rate replaces Space Exploration's default diminishing returns while preserving its planet-size yield multiplier.

Settings

| Setting | Type | Default | Range | |---------|------|---------|-------| | Diminishing rate per miner | Map | 10% | 0-100% |

Set to 0% for no diminishing returns (all miners at full efficiency).

Configurable at any time via Map Settings - no restart required.
