Opening Junction Settings
Tube junctions are special blocks that split a single item stream into multiple outputs or merge multiple inputs into one line. Right-click a junction to open its configuration menu.
Port Modes
Each connection port on a junction can be set to input, output, or disabled. The menu shows all connected sides. Set the ports according to your desired flow: one input from an extractor and multiple outputs to different machines, for example.
Redstone Switching
Junctions support redstone-controlled port modes. When powered by redstone, a junction can switch which ports are active, allowing you to route items to different destinations dynamically. Configure this in the junction menu by assigning redstone behavior to specific ports.
Testing Routes
After configuring ports, send items through the junction and verify they exit from the correct sides. Use flow sensors downstream to confirm items are reaching their intended destinations.
