How to transfer resources from the lower floor to the upper one?

Use the DeepCore Cargo Elevator.

1. Research DeepCore Interlevel Logistics.
2. Craft a DeepCore cargo elevator.
3. Place it on the upper floor. The matching lower endpoint is created automatically on the next prepared level, so the same area must be clear on both floors.
4. On the lower endpoint, connect belts to the west or east ports:

• Belt facing toward the elevator = sends resources up.

• On the upper endpoint:

• Belt facing away from the elevator = outputs resources arriving from below.

There is no manual up/down setting; each port determines its role from the connected belt direction. Both directions can operate simultaneously, and output filters can be configured by opening the elevator GUI.

Thank you
