Smart Quality Condenser

Upgrade items in bulk and keep a chosen stock of higher-quality items available through logistic robots.

How to use

Research and build a quality condenser. Supply power and quality modules, and place it in roboport logistic coverage.
Open the condenser and select Targets.
Click an empty slot, choose an item and quality, and enter the Stock to keep. Press Enter or Confirm.

Each slot shows the item, quality badge, and stock amount. Click a slot to edit it, or right-click to remove it. Each condenser has its own targets, which also copy with blueprints and settings copy/paste.

For example, 50 rare beacons keeps 50 rare beacons available in the logistic network. Robots deliver lower-quality beacons and collect the finished ones. Taking finished items from storage creates demand again. Multiple items and qualities can run together.

Requirements and behavior

Logistic robots, lower-quality items in provider, storage, or eligible buffer chests, and room to store finished items.
No external combinators, chests, inserters, or circuit wires are needed.
Quality modules determine the upgrade yield. A small batch with a low upgrade chance may need more items before it can produce an upgrade.
Targets must use an unlocked quality above Normal. Full output storage pauses the condenser; robot delivery timing can produce small surpluses.
Turn Automatic logistics off to use the condenser manually.

Existing saves

This is a standalone fork of Quality condenser (forked). Disable that mod when enabling this one. Existing condensers, inventories, modules, and blueprints are preserved.

Upgrading from 0.1.0 moves target-combinator settings into the paired condenser and refunds the retired combinator's ingredients.
