FAQ & Troubleshooting

FAQ

1. How can I get better scan details?

  • Adjust the IR camera’s exposure while scanning:
    • Red = overexposed, Blue = underexposed. Aim for a balanced setting.
  • Keep the scanner close to the object (but not too close to lose tracking). This helps capture finer details.
  • During point cloud optimization, use a smaller point distance (e.g., 0.1mm for small objects).
  • When creating the final mesh, ensure you’ve got enough model faces to preserve detail.

2. How do I scan the bottom of an object?

  • Use Creality Scan’s multi-project merging:
    • Scan the visible part first, pause, then rotate the object to capture the hidden side.
    • The software will align and merge these scans into a complete model.

3. When should I use a scanning pad?

  • For small objects like earbuds or medals, place 3mm markers on the scanning pad and use marker point mode for precise scanning.

4. When do I need the USB 2.0 power cable?

  • If your computer can’t power the scanner (often an issue with older USB ports), connect an external charger using the USB 2.0 cable.
  • For USB 3.0 connections with sufficient power, you usually won’t need this cable.

5. When should I use marker point mode or texture mode?

  • Marker Point Mode: Best for objects with smooth or repetitive surfaces; apply the provided reflective markers.
  • Texture Mode: Use this if the object has clear surface textures that the scanner can easily track.

6. When is calibration needed?

  • If the scanner hasn’t been used for 3+ months or after any bumps or drops. Handle it carefully to maintain accuracy.

7. Can calibration cards be swapped?

  • No, each calibration card is unique to its scanner. If you’re using a card for the first time, scan its QR code to bind it to your scanner.

8. How should I store the calibration card?

  • Store it in its box after use to prevent dirt, scratches, or bending. Damage to the card can affect accuracy.

9. How do I calibrate the scanner?

  • Connect it to your computer, open CrealityScan, go to [Device], click [Calibration], and follow the on-screen instructions.

Troubleshooting

1. My Windows computer won’t connect to the scanner.

  • Use a USB 3.0 port (usually blue or red) directly on your PC’s back panel.
  • Make sure your system runs Windows 10/11 64-bit.
  • Ensure the Creality Scan installation path is in English only.

2. I can’t see the preview video on Windows.

  • Check if your computer meets the scanner’s minimum requirements.
  • Use the provided power adapter and ensure it’s connected properly.
  • In Device Manager, confirm the scanner appears under “Cameras” as “CR-Scan Otter.”
  • In Windows Settings > Privacy > Camera, ensure desktop apps can access the camera.

3. I can’t see the preview video on my Mac.

  • Confirm your Mac meets the scanner’s minimum requirements.
  • Use a dedicated USB Type A-to-Thunderbolt or USB3 adapter (avoid multifunction adapters).
  • Install CrealityScan directly into the Applications folder (not in a sub-folder).
  • Update the scanner firmware to the latest version.

4. My USB 3.0 port is recognized as USB 2.0.

  • Try unplugging and reconnecting the USB cable quickly.
  • Ensure the USB cable is connected to the USB 3.0 port on your PC first, then to the scanner’s USB-C port.

Creality Otter

I used to think 3D scanning was complicated – then I met the CR-Scan Otter. It’s crazy how easy this little device makes it! I’ve already scanned a bunch of things and am figuring out new tricks every time. If anyone’s curious about getting into 3D scanning, this is definitely a great start.
