FastFurnaces

Overview

FastFurnaces adds a higher tier of many mainline production machines, including:

Electric Furnace
Chemical Plant
Refinery
Offshore Pump
Small Pump
Long Inserter
Mining Drill
Beacons
Chests
BobMods solar and steam

Every feature is indivdually controllable in the settings.

Special Machines

In most cases, these upgraded versions are simply more expensive but more powerful (usually faster, hence the name). However, a few upgrades are special. In particular, enhanced mining drills are actually far more efficient and clean compared to their base counterparts, without being hugely faster. Beacons actually have two additional tiers, each gaining module slots, range, and transmission efficiency (and extreme power cost).

Modules

FastFurnaces also adds T4 and T5 modules. These, especially the production modules, are generally unlimited compared to vanilla ones, and can get stupidly overpowered, to the point where the base game had a patch to prevent numerical overflow caused by stacking them.

Configuration Settings

This mod contains several config options to modify values and behaviors - such as for balance or server safety concerns, or simply personal taste - to your preferences. Note that several settings may have bounds imposed on their values, either logically or explicitly; these can usually be seen in the actual settings files or ingame. These are listed in order found in the source code, which is generally the order in which they were added; They may be present in a different order ingame or in the configuration files.
The settings for the mod, when installed, can be found ingame, in the mod settings menu.
