Troubleshooting

How to proceed in the event of a job interruption

If the job was interrupted, DentalCNC displays a corresponding message.

If the compressed air is insufficient

• Check the following:

• The manometer of the compressed air regulator
• The installation of the pneumatic hoses
• Your compressor

If the vacuum is insufficient

• Check the suction hose and your suction unit.

If the cooling liquid flow rate is insufficient

1. Check if there is enough cooling liquid in the tank
2. Check if the cooling liquid and the tank including the filter are clean.

How to proceed in the event of a machine malfunction

A machine malfunction was recognized by the internal control unit in case of a critical event. The working chamber will be illuminated in red. DentalCNC displays the error message and error code that was sent by the control unit.

1. Record the error message and error code that is displayed.
2. Restart the machine and the CAM computer The computer that is connected to your machine and which runs DentalCAM and DentalCNC.. If the problem persists, continue with the next step.
3. Disconnect the machine from the electrical source and prevent it from being restarted.
4. Contact customer service. Have the error message and error code readily available.
5. To remove a blank from the working chamber, open the working chamber door manually if necessary.

How to proceed in the event of a tool breakage

If a tool breaks during machining, the machine will not recognize this immediately. Instead, the spindle will continue to move with the broken tool. The tool breakage will be recognized upon the following events:

• The next regular tool change

A tool breakage can be caused by the following:

• The tool was damaged or worn
• The tool was put into the wrong tool position or was manually inserted into the spindle at the wrong time. As a consequence, it was not suitable for the processing step.
• The distribution of the objects in the blank (“nesting”) was not correct.

If a tool breaks, do the following:

1. Open the working chamber door.
2. Remove all parts of the broken tool from the working chamber and the collet chuck.
3. Re-add the tool to the virtual ATB and virtual tool magazine in DentalCNC.
4. If the spindle picked up the tool from the tool magazine, check if the tool was inserted into the correct position. Insert a spare tool into the correct position in the tool magazine.
5. If you manually inserted the tool into the collet chuck, check if the broken tool corresponds to the tool type which you were prompted to insert. Have a correct spare tool ready.
6. Close the working chamber door.
7. Resume the job.

If tools break regularly, you can find additional information in the troubleshooting section:

How to proceed in the event of a power failure

While the machine is not receiving power, you have no access to the working chamber.

• After a short power failure, restart the machine and the CAM computer The computer that is connected to your machine and which runs DentalCAM and DentalCNC..
• If you need to access the working chamber in case of a longer power failure, perform an emergency opening of the working chamber door.
• If you need to access the multi-purpose compartment, do the following:
1. Close the main external compressed air supply valve.
2. Carefully pull the flap down with your hands.

Loud machining noise

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.
