What You’ll Need to Start:

Before you dive into the exciting process of using your CeConstructor, make sure you have the following essentials ready:

  1. The CeConstructor Hardware: This includes all the components found in your package.
  2. CeStudio Software Installation: Download and install the CeStudio software from the CePortal. Your user login credentials are included in your package, so you’ll have exclusive access to this essential tool.
  3. CeController Smartphone App: To enhance your experience, download and install the CeController Smartphone App, available from the CePortal using the same user credentials found in your package. The app will soon also be accessible via the Play Store (for Android users) and the App Store (for iOS users).

First Start

  1. Set Up Cameras: Screw the cameras with the star screws onto the camera base (curved shape) at the smallest distance, thus the smallest base length.
  2. Attach Base to Tripod: Screw the base onto the calibration tripod (honeycomb) with another star screw. With the fourth star screw (with a rubber knob), you can screw on the third leg of the calibration tripod and adjust its height.
  3. Remove Lens Caps: Take the plastic caps off the camera lenses.
  4. Connect Cameras: Connect the two cameras to two free USB ports on the PC.
  5. Start CeStudio: Start the CeStudio application (Installation instructions on the CePortal).
  6. Enter License Key: Enter the license key.
  7. Choose Cameras: Choose the left and right camera in the setup window. View is always from behind the cameras, looking at the object to be digitized. Hover over the selection fields for a preview.
  8. Start Main Window: Start the main window.
  9. Initialize Cameras: Under the Settings tab in the main window, the cameras will be initialized. Press Start.
  10. Switch to Camera View: Switch to the camera view at the top.
  11. Adjust Focus: If the cameras are not sharp at a distance of about 30 cm, you can adjust them by turning the lens with a small screwdriver.
  12. Calibrate Cameras: Perform the camera calibration as described in the manual. Orientation can be provided by the old German tutorial: Link
  13. Calibrate Probes: Perform probe calibration with both probes. The probes are only roughly calibrated from the factory, so precise calibration is necessary at the start. See the manual for probe calibration and watch the old tutorial: Link
  14. Adjust Base and Lenses: You can now increase the base between the cameras and adjust it to the object size. This requires adjusting the lens focus and the base distance of the cameras and performing a new camera calibration.
  15. Start Construction: You can start constructing under the Construct tab. Detailed instructions are provided in the CAD Construction section of the manual.

Subsequent Starts

  1. Adjust Cameras?: Have the cameras been adjusted to the object size? Yes -> New camera calibration. No -> Next step.
  2. Calibrate Probe?: Is the probe calibrated? (See probe calibration to know when a probe decalibrates). Yes -> Next step. No -> Calibrate probe.
  3. Start CAD Construction: Start with the CAD construction under the CAD Construction tab.

Additional Tips:

  • The approximate Z-accuracy is displayed at the top of the screen. It describes the ratio of the distance between the probe and the cameras to the base distance, which is the largest factor affecting accuracy. For a better value, reduce the distance from the cameras to the probe or set the cameras further apart.
  • The large probe is better recognized at distances > 30cm.
  • Hold the probe as still as possible at the moment of capturing a point.
  • There are three acoustic tones and three colours of the cameras in the virtual workspace: Green – The probe is detected. Orange – The angle between the probe and the cameras is bad. Red – The probe is not found.
