Masterful Machinery Upgraded

[1.21.1-0.8.0] - 2026-09-20

Added

• Order MM items from the Replication Terminal. A mm:replication/link port puts a machine's recipes in the Terminal next to everything else. Ask for an item and the machine makes it, and it lands in the Terminal. Items Replication has no matter value for can be ordered too. Needs Replication.
• Ars Nouveau Source port. With Ars Nouveau installed, mm:ars_nouveau/source ports hold Source, set with capacity and range.
  • Input ports pull from nearby source jars, and sourcelinks can fill them directly.
  • Output ports feed nearby jars and Ars machines such as the imbuement chamber.
  • Source relays cannot be pointed at a port; use jars or sourcelinks.
• Autocraft MM recipes from AE2. With Applied Energistics 2 installed, a mm:ae2/pattern port joins an ME network and offers the machine's recipes in the crafting terminal. Order one and the ingredients are taken from storage, the machine runs, and the result comes back. patternPriority picks which machine wins when several can make the same item.
  • Matter can be an ingredient when Replication AE2 Bridge is installed.
  • Only recipes with an item or fluid on both sides can be ordered, since AE2 cannot carry energy, Source or radiation.
• See how full a Source port is three ways: the block itself brightens as it fills, its screen has a bar, and Jade shows a bar when you look at it.
• Extra blocks join up. Place them side by side and their frames merge into one panel, with each block keeping its own face. connectGroup decides what merges with what; without it a block only joins copies of itself.

Fixed

• Machines no longer craft for free. A recipe with a per_tick input kept running when the port it draws from was empty. It now waits until there is enough, and carries on by itself. Affects energy, fluid, matter, Source and radiation.
• Machines that stopped noticing their ports. Filling a machine sometimes did nothing until a block was broken next to it. Idle machines now find their ports again on their own.
• JEI no longer stacks copies of a machine and its recipes every time resources are reloaded.
• Two config files claiming the same id. Giving two ports, controllers or extra blocks the same id has always stopped the game, but it never said where the clash was. It now names both files. Using one block in as many structures as you like is unaffected.
• A missing port is reported. A structure that uses a port no config defines now says so in four places: a summary when the world loads, a message to operators joining the world, a red line on the structure's JEI page, and the debug tool's dump. Before, the machine quietly never formed and nothing said why.
