Troubleshooting Tips for the Cobalt



A compilation of tips and troubleshooting information when using the Cobalt with BuildIT software.


To run BuildIT software with the Cobalt Imager requires the following:

  • Server (also called SDK Server Software or Firmware) version or greater.
  • Driver (also called Cobalt Interface Utility) version or greater.
  • BuildIT 2018 or greater.
    • BuildIT 2018 SP1: Added the Diagnostic and Compensation buttons
    • BuildIT 2018 SP2: Point clouds are in grey scale


  1. The Cobalt S/N is not shown in the Broker window or shown but status remains red.
    1. Disable the Wifi connection on the laptop/computer in use.
    2. Make sure Ethernet IPv4 properties are set to obtain automatic IP.
    3. If a Cobalt is listed but status is red, make sure the correct serial number is listed. The software sometimes remembers previously connected units.
  2. The Cobalt is found in broker and the diagnostics can be opened, but no image appears in the GUI and no data is acquired when recording a point cloud.
    1. Disable any VPN connections (if applicable) on the laptop/computer in use.
  3. Clicking on Edit button in the Broker window has no effect and the Cobalt Capture GUI is not shown.
    1. Make sure that the Cobalt Interface (driver) is installed. See the Requirements section above.
    2. Launch the Windows Task Manager and see if an instance of "Faro3DImagerCaptureProcess.exe" is already running. If so, try ending that process then try clicking on the Edit button again to launch the Capture GUI.
    3. When starting BuildIT software, right click the icon and select "Run as administrator".
  4. The Cobalt does not detect targets.
    1. Make sure that an exposure of ~20ms is set to capture targets and that the target capture setting is enabled.
    2. Make sure the Cobalt range is set correctly using the range finder. Sometimes the targets can be seen in the GUI, but will be outside of range for capturing targets.
    3. Compensate the Cobalt. For details about how to perform a compensation, download the Cobalt User Manual or view the following video: Cobalt Compensation in BuildIT
    4. For more information see: Some Targets Are Not Identified While Using Measure and Scanning with the Cobalt 3D Imager
  5. The rotary table (directly connected to Cobalt) rotates and Cobalt seems to be scanning properly, yet only one scan is captured.
    1. Downloaded the latest version of the Driver. See the Requirements section above.
    2. If already installed, try reinstalling and when prompted click Repair in the installer window.
  6. Rotary table compensation or alignment failed.
    1. Verify the correct range to rotary table using the range finder and that the targets are in view.
    2. Take a single point cloud scan of the rotary table with targets enabled and exposure set to  ~20ms - 25ms.
    3. If no targets are captured, compensate the cobalt. For details about how to perform a compensation, download the Cobalt User Manual or view the follwing video: Cobalt Compensation in BuildIT
  7. For other known issues, see the articles listed under the Troubleshooting Tab on the Cobalt homepage within this Knowledge Base.
