Troubleshooting – fix problems yourself

General troubleshooting

The actual sound emission of the machine varies heavily depending on the manufacturing material and the machining conditions.

  • If the machine is exceptionally loud, check the following operating conditions:
  • Cleanliness of the blank holder
  • Condition of the tools
  • Quality of the blank
  • If loud noise cannot be avoided, wear ear protection during machining.

This can be caused by the following:

  • The .stl file is corrupt.
    • Re-export the .stl file from the CAD application after correcting CAD settings.
  • Multiple construction.info files exist in the folder path (DentalCAM currently supports only 1 construction.info file per path).
    • Remove all unrelated construction.info files from the directory where the .stl file exists.

The Windows® system memory (RAM) or the available amount is insufficient.

  • Check the size of the Archive folder. If it is unusually large (more than 15–20 GB), delete blanks that have been completely utilized.
  • Reboot the computer to free up memory resources.
  • Close all unnecessary applications.
  • In the Task Manager (Windows® 10), check if there are enough memory resources available:
    1. Press CTRL + Shift + Esc.
      • The Task manager window opens.
    2. Select the Performance tab.
      • In the left column below the Working memory label, the currently used and maximum working memory displays.

The .stl has been saved in ASCII format rather than binary format.

  1. Open the folder containing the corresponding STL file in Windows® Explorer.
  2. Right click on the STL file and select Open with from the list.

  3. Select a text editor (e.g. Notepad, Wordpad etc.).

    • If it appears as a text document it is ASCII format.

  4. Re-export this file from your CAD application in binary format to convert this file from ASCII to binary format.

This error is caused by damaged STL files whose thumbnails cannot be deleted by DentalCAM.

The .stl has been saved in ASCII format rather than binary format.

  1. Open the folder containing the corresponding STL file in Windows® Explorer.
  2. Right click on the STL file and select Open with from the list.
  3. Select a text editor (e.g. Notepad, Wordpad etc.).
    4. If it appears as a text document it is ASCII format.
  4. Re-export this file from your CAD application in binary format to convert this file from ASCII to binary format.

The selected .stl file has read only or limited file permissions for the current user.

  • Verify that the .stl file does not have read-only access rights.
  • Verify that the DentalCAM installation path does not have read-only access rights.
  • Copy the .stl file to a local drive, restart DentalCAM and try to nest the .stl file.

After DentalCAM 7/8 installation or Windows® update, enable .Net Framework 3.5 and 4.7 from the Windows Features menu in Windows®.

  1. Navigate to Control Panel > Programs & Features.

  2. Select Turn Windows Features on or off.

  3. Activate .NET Framework 3.5 and .NET Framework 4.7.

  4. Select OK.

  5. Update DentalCAM & DentalCNC again to the latest version with an installation package.

    If you need an installation package, contact customer service.

Null is a variant subtype used to indicate that a data item contains no valid data.

  • Backup user data and reinstall DentalCAM.

There are also error messages other than DentalCAM errors and Run time errors that are shown by Windows®. Following you find the error messages and possible solutions for the elimination of the errors.

Conflicting drillings have been detected.

  • Use the editing function for specifying the drilling range to remove the duplicate drilling (you can find the corresponding instructions here).

After DentalCAM 7/8 installation or Windows® update, enable .Net Framework 3.5 and 4.7 from the Windows Features menu in Windows®.

  1. Navigate to Control Panel > Programs & Features.

  2. Select Turn Windows Features on or off.

  3. Activate .NET Framework 3.5 and .NET Framework 4.7.

  4. Select OK.

  5. Update DentalCAM & DentalCNC again to the latest version with an installation package.

    If you need an installation package, contact customer service.

The Windows® library is required for opening the residual material display in DentalCAM.

  • Install Microsoft Visual C++ 2013 Redistributable (x64) (or use the provided download link)

This error may occur after a Windows® update.

  • Ensure that you are opening DentalCNC as administrator or with administrator rights.

  • Reinstall the DentalCAM software using administrator rights.

Other problems can occur during the operation of DentalCAM. Following you find the most common problems that occur and solutions for the elimination of the problems.

This can be caused by the following:

  • An incorrect prefabricated abutment blank was inserted into the blank holder.
    • Ensure that the correct prefabricated abutment blank is used.
    • Replace an incorrect prefabricated abutment blank with a correct one.
    The correct prefabricated abutment blank is defined by the CAD application in which the STL file was created.
  • Measuring problem due to a mechanical problem with the collet chuck.
  • Software conflict
    • Update DentalCAM to the latest version.

Windows font size has been increased to more than 100%.

  1. Go to Control Panel > Appearance and Personalization > Change the appearance of your display > Make text and other elements larger or smaller.
  2. Set the size of texts to Smaller – 100 % (default).

The following issues require you to change Windows® settings. You may need administrator privileges for this.
