To upgrade to the 1.5 Wuling Factory layout in Arknights: Endfield, you must complete the 1.4 base setup first. The 1.5 blueprint builds directly on top of the 1.4 infrastructure, so attempting to place it on an un-upgraded grid creates grid snap errors and power failure.

Prerequisites and Setup Sequence

Ensure your 1.4 setup is fully constructed and functional before importing or snapping the 1.5 blueprint modules. Once your baseline infrastructure is verified, follow this deployment sequence:

  1. Align Central Power: Route primary power conduits directly to the central hub to ensure steady electrical distribution across all production modules.
  2. Install the Overflow Protector: Place the Overflow Protector at main output junction nodes before attaching auxiliary lines.
  3. Connect Secondary Lines: Run secondary supply and transport lines into the main assembly network.
  4. Group Processing Units: Cluster refining units according to their shared material input requirements to shorten transit paths between raw inputs and refined outputs.
  5. Inspect Modular Edges: Check corner boundaries for spatial clipping issues that interrupt automated pathing logic.

Role of the Overflow Protector

High-volume factory layouts can generate materials faster than storage or secondary lines can absorb them. When output storage fills up, backup backpressures the assembly line, causing production to stop.

The Overflow Protector acts as a pressure valve at key intersection nodes. When a primary line backs up, the module redirects excess materials into designated overflow routes, allowing refining machinery to continue operating without requiring manual line clears.

Power Constraints and Operational Limits

The 1.5 blueprint increases overall production output, but it also imposes significantly higher electrical demands than previous configurations.

  • Power Generator Requirements: If refining machinery cycles on and off repeatedly, your electrical grid is overloaded. Upgrade your power generators before adding additional auxiliary production lines.
  • Production Line Flexibility: The 1.5 layout maximizes high-volume throughput for fixed production cycles. If your operation requires frequent recipe switching or material re-routing, a modular layout will require less manual recalibration of input-output ratios.
  • Routine Maintenance: Periodic checks of output logs and drone transport paths help identify blocked tiles or missing electrical connections created during module placement.
