5. Prospective job duration
6. Arrows to browse through the available jobs
7. Number of current job / number of available jobs
8. Color code of the required tool magazine
9. Icon for starting the current job
10. Icon for deleting the current job
2. Use the arrows in the left bottom corner to select the desired job.


 

3. Verify that the elements [2], [3], [4] display as required:
1. Ensure that the mounted blank corresponds to [2] (if not:  Mounting and removing blanks).
2. If displays in [3], mount the correct tool magazine ( Attaching and exchanging tool magazines).
3. If displays in [4], replace all worn tools ( Managing tools).
4. To start machining, select the depicted icon.
• The following happens:
1. If required, the working chamber door closes.
2. The machine determines the size of the mounted block with the spindle. If the measured block size differs from the block size which is stored in the job file, a corresponding message displays on the touchscreen.
5. If the machine determined a different block size, continue as follows:
   1. Check if the mounted block is suitable for processing the current job.
   2. If the block is suitable, start the job by selecting on the touchscreen.
   3. If the block is not suitable, abort the job by selecting on the touchscreen. You need to restart the job with a suitable block.
• If the job was started, the following happens:
1. The machine starts processing.
2. The working chamber is illuminated in blue.
3. The remaining machining duration displays on the touchscreen.


 

1. Job name, patient information
2. Icon for canceling the job
3. Job end time
4. Prospective remaining job duration

The remaining job duration is an estimation based on a self-learning function.

6. If using exocad ChairsideCAD, do not shut down your CAD computer or disconnect it from the network until machining has finished. Otherwise, you may have to restart your machine and the job.
7. Wait until the machine has finished.
• The working chamber door opens. The following dialog displays on the touchscreen.


The dialog after a job has been finished

8. Remove the blank from the working chamber and check whether the job has been executed correctly.
9. If you are satisfied, select the depicted icon on the touchscreen.
• The job is marked as finished and no longer displays in the Jobs section.

You can restore finished jobs with DentalCNC. Read the corresponding documentation for more details.

10. If you need to repeat the job, select the depicted icon on the touchscreen.
• The job continues to display in the Jobs section. You can restart it as required.
11. Leave the working chamber door open so that the working chamber can dry.

You can cancel machining at any time. You need to restart the job with a new blank. You cannot continue the job with the used blank because the machine will not recognize this blank and you will receive an error message.

1. To cancel machining, select the depicted icon.
• The machine prompts you to confirm the cancellation.
2. To confirm your choice, select the depicted icon.
• The spindle puts the tool which is currently in the collet chuck into the tool magazine. The working chamber door opens.
3. If the working chamber is wet, leave the working chamber door open so that the working chamber can dry.

A job will be interrupted in the following cases:

• The compressed air supply is not sufficient
• The cooling liquid flow is not sufficient

An interrupted job will normally be continued automatically after the error is corrected.

A job will be aborted in the following cases:

• In case of a machine malfunction
• In case of a tool breakage
• In case of a power failure

If a job was aborted, you have to restart it.

How to proceed in the event of a job interruption

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

If the compressed air is insufficient

1. Wait a couple of seconds. This may already solve the problem.
2. Restart the machine.
3. If the problem persists, contact customer service.

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. The touchscreen 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.

You need to restart the job with a new blank. You cannot continue the job with the used blank because the machine will not recognize this blank and you will receive an error message.

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

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. You also have no access to the drawer.

• 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 to the multi-purpose drawer, perform an emergency release of the drawer.

You perform an emergency opening as follows:

1. Switch off the machine at the main power switch. Disconnect the machine from the eletrical source.
• You can manually open the working chamber door.

The working chamber door should move sluggishly, but evenly. If the movement is jerky or the working chamber door gets stuck, do not use excessive force.

2. Open the working chamber door by pushing it straight and evenly upwards with both hands.
3. If the door can only be moved by making a major effort, make sure that the guide rails at the back of it are clean.


 

4. If the working chamber is wet, leave the working chamber door open so that the working chamber can dry.
5. Close the working chamber door by carefully pushing it downwards with both hands.

To unlock the Multi-purpose drawer in an emergency, you need to remove the back panel cover of the machine.

You can remove the back panel cover as follows:

1. Switch off the machine at the main power switch.
2. Disconnect the machine from all lines.
3. Grab the bottom edge of the back panel cover and pull it towards you as indicated by the arrows:


 

4. To reattach the back panel cover, do the following:
1. Align the top edge of the machine and the cover so that the start button and main power switch lie in the center of the respective openings.
2. Push the cover against the machine housing.
• The cover is held in place by magnets.

In case of a longer power failure, you can manually open the multi-purpose drawer as follows:

1. Machines with internal CAM computer The computer that is connected to your machine and which runs DentalCAM and DentalCNC.: Remove the back panel cover.

2. Machines with external CAM computer The computer that is connected to your machine and which runs DentalCAM and DentalCNC.: Remove the protective cap (marked orange).

   

    

3. Insert a screwdriver with 5 cm minimum length into the depicted opening at the backside of the machine.
