7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Marbles jam or stop moving. | Misaligned track pieces, debris in the track, or issue with the lifting mechanism. | Check all track connections for proper alignment. Remove any foreign objects from the track. Inspect the lifting mechanism for obstructions or damage. Ensure the mechanism is fully engaged and moving freely. |
| LED lights do not illuminate. | No power, loose connection, or faulty LED component. | Verify the USB-C cable is securely connected to both the model and a working power source. Try a different USB power adapter. Check all LED wiring connections within the model. |
| Parts do not fit together. | Incorrect part orientation or residual plastic from the frame. | Refer to the instruction book to confirm correct part orientation. Carefully trim any excess plastic from the edges of the pieces. Do not force parts together. |
