Troubleshooting#

The network doesn't work#

• Is there exactly one controller, and is it powered? (OFFLINE = no energy, CONFLICT = two controllers.)
• Are all devices touching each other or linked by cables? Remember the 1-second re-scan.
• Did you connect through a block that is not a Simple Byte Storage node? Only Simple Byte Storage devices and cables carry the network.

Items don't go into the drive#

• Is a whitelist set on the drive? Empty accepts everything.
• Is the network full (used / max bytes)? Add cells.
• A higher-priority drive with a whitelist may be taking the items you expect elsewhere.

Order button says it can't craft#

• Missing base materials — the confirmation window lists them.
• No Assembler / no memory card in the Assembler: crafting patterns need an Assembler with a buffer cell.
• Processing patterns need a Pattern Bus that holds the pattern and touches a machine.

Assembler is stuck#

Open it. The GUI shows the reason: no card, not enough resources, card busy or too small, network offline or full.

Pattern Bus does nothing#

• Is the machine adjacent on a face with an item handler?
• Is the machine's input full or its output blocked?
• Is the network online and the pattern a Processing pattern?

Wireless Terminal won't open#

Check energy (100 FE needed), that the Terminal's chunk is loaded, and that it still exists and is bound.

Logic Bus shows ERROR#

See the table on Scripting API → Errors. Fix the script, Save, then Run again. An error always stops the bus.

Logic Bus is running but nothing happens#

• The network may be offline (the bus idles when offline).
• side("…") returned null: wrong direction, or the neighbour has no inventory.
• The interval might be long: check the interval shown in the terminal (the server enforces minInterval).
• side(dir, id) returned null: no bus has that ID (case-sensitive), or the buses with that ID have no inventory on that side. Compare with the ID list in the Logic Bus GUI or the terminal, and buses(id).
• Use log(…) to see what the script sees.

Build problems#

See Building from Source. When opening an issue, attach the Gradle log and the output of latest.log.
