====== I'm getting bad scan results - troubleshooting ======

  * Keep your FlexScan3D projects locally. Things go weird when your project is stored in a networked folder.
 
  * I'm not getting any or partial scan results
    * Is the cut plane still active? Remove cut plane.
    * Is the Z-filter set correctly? 
      * measure and re-set the Z-min value
      * measure and re-set the Z-max value
    * Turn on bounding box: this way it's easier to spot if a scan contains information or not.

  * Using the rotary table, my scan is scattered in a circular pattern
    * do the rotary table calibration

  * I'm getting glitch-like stripes instead of a clean scan
    * Is the object reflective? Use a matting spray
    * Is the object transparent? Use a matting spray 
    * does the object [[https://en.wikipedia.org/wiki/Subsurface_scattering|scatter the light underneath it's surface]]? Use a matting spray
    * Try position the object a little closer or further away from the scanner
    * Change the image exposure a little (darker, brighter). Do this only inside the scanning software. **Never do this on the projector itself.**

  * Out-of-sync warning
    * increase pattern delay. Check the scan-images to see if each image has the right projected pattern on it.

  * 3D object rotates slowly and can't be stopped
    * stop "demo mode" in the contextual menu.


=== Special cases ===
  * scanning and processing takes long (capture time: ± sec, processing time: ±70 sec)
     * the bounding box is empty
     * system check is OK
     * making a scan to define the cut plane doesn't take abnormally long
     * Generate: "capture only" is also slow. Generating a mesh from the images doesn't work
     * the problem persists after restore defaults and reboot
     * The scan-images look good.
     * This problem was with FlexScan3D V3.3.5.8 (64bits)
     * A reinstall of the program fixed these problems
