Servos

Servos are items that can be installed on itemduct and fluiduct connections. They extract items or fluids from adjacent blocks and insert them into the ducts.

Usage

Installation

A servo can be installed on an itemduct or fluiduct connection by using it on the connection. It can be removed by using a wrench on it.

Configuration

An installed servo can be configured by using it. The available options depend on whether the servo is installed on an itemduct or on a fluiduct.

A servo’s configuration also affects items or fluids that are inserted into the duct by the connected block.

A servo’s configuration can be saved on a redprint to be copied to other servos, filters or retrievers.

Redstone control

By default, a servo is only active when powered with redstone. However, this is configurable. A servo can be in one of three modes:

Ignored

Redstone control is disabled. The servo is always active.

Low

The servo is active when not powered. When powered, it becomes inactive.

High

The servo is only active when powered. This is the default mode.

Item transfer

When installed on an itemduct connection, an active servo extracts items from the block it is connected to.

Items are extracted from a block in stacks. The maximum size of each stack and the speed at which stacks are extracted depends on the servo’s tier. The maximum stack size can be configured to be lower.

Servos at higher tiers give extracted items a speed boost, causing them to move faster through the itemducts.

Item filtering

A servo can be configured to only extract items that match a given list of items. It has various options that determine how this list is used to match items. Some of these are only available at higher tiers.

Blacklist/Whitelist

Treat the list of items as a blacklist (extract all items except these) or as a whitelist (only extract these items). The list is used as a blacklist by default.

Metadata

Match items by their exact metadata / damage value. This is used by default.

NBT

Match items by their exact NBT data. This is used by default.

Ore Dictionary

Match items that are considered equivalent, like the various versions of copper and tin ingots added by different mods. This is ignored by default.

Mod Owner

Match items that are added by the same mod. This is ignored by default.

Item routing

At higher tiers, a servo can be configured to prefer sending items to certain blocks in the network.

Nearest-First

Items are sent to the connected block that has the shortest path to it first, taking into account dense and vacuum itemducts. This is the default mode.

Furthest-First

Items are sent to the connected block that has the longest path to it first, taking into account dense and vacuum itemducts.

Random

Each item is sent to a random connected block.

Round Robin

Items are sent to each connected block in a repeating order.

Fluid transfer

When installed on a fluiduct connection, an active servo extracts fluids from the block it is connected to. The rate at which fluids are extracted depends on the servo’s tier.

Fluid filtering

A servo can be configured to only extract fluids that match a given list of fluids. The servo has various options that determine how this list is used to match fluids.

Blacklist/Whitelist

Treat the list of fluids as a blacklist (extract all fluids except these) or as a whitelist (only extract these fluids). The list is used as a blacklist by default.

NBT

Match fluids by their exact NBT data. This is used by default.

Tiers

Servos come in five tiers.
