The '''buffer chest''' is a large advanced storage item that is part of the [[logistic network]]. It functions as both a [[requester chest]] and, in a limited capacity, a [[passive provider chest]]. It is so named because it functions as an "in-between" chest for ferrying items from [[provider chest]]s to the player or [[construction robot]]s.

Like requester chests, buffer chests can be configured to request of a specified number of up to 12 types of items from the logistic network. [[Logistic robot]]s will then bring the specified items from provider chests or [[storage chest]]s until the request is met. In addition, similar to a passive provider chest, any items contained in a buffer chest are made available to construction robots and logistic requests from the player. However, items in a buffer chest are '''not''' used to fulfill requests from requester chests and other buffer chests.

The buffer chest is useful for readying construction materials or supplies for the player in a specific location, without having to transport the supplies to the chest by belt. This functionality is unique to the buffer chest and cannot be replicated with other logistic chests:
* Provider chests and storage chests can provide items to the player or construction robots, but there is no way to force logistic robots to move an item to a specific provider or storage chest.
* Requester chests can request items at a specific location, but the items within are not available to construction robots or logistic requests from the player.
* Requesting an item using a requester chest and then inserting it directly into a provider chest does not work, as logistic robots will simply take the item out of the provider chest and put it back in the requester chest. This creates an infinite loop and ties up logistic robots with a meaningless task.

The buffer chest is a large advanced storage item that functions as both a requester chest and a passive provider chest. The buffer chest functions as an "in-between" chest for ferrying items from provider chests to the player, construction robots, or requester chests.

Like requester chests, buffer chests can be configured to request of a specified number of up to 12 types of items from the logistic network. Logistic robots will then bring the specified items from provider chests or storage chests until the request is met. In addition, similar to a passive provider chest, any items contained in a buffer chest are made available to construction robots, logistic requests from the player, and requester chests that have the "Request from buffer chests" checkbox checked. However, items in a buffer chest are not used to fulfill requests from other buffer chests.

Uses

  • The buffer chest can act as a central supply point to the player,

  • ... or as a more localized supply for construction,

  • ... or as a filter for logistic storage.

Achievements
