To manually start the drying program,
select the depicted icon in the
view in DentalCNC.
The machine dries the working chamber for 15
minutes.
The built-in ionizer is also part of the DirectClean Tech-
nology. It is automatically activated for suitable jobs to
make cleaning the working chamber easier.
Job interruptions and job abor-
tions
A job will be interrupted in the following cases:
The compressed air supply is not sufficient
n
The vacuum in the working chamber is not suf-
n
ficient
The cooling liquid flow rate is not sufficient
n
An interrupted job will normally be continued auto-
matically after the error is corrected.
A job will be aborted in the following cases:
In case of a machine malfunction
n
In case of a tool breakage
n
In case of a power failure
n
If a job was aborted, you have to restart it.
DentalCNC allows you to resume the job from
the last machining step. For more information,
see the corresponding documentation.
How to proceed in case of a job inter-
ruption
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
n
The installation of the pneumatic hoses
n
Your compressor
n
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 case of a machine mal-
Machining
function
A machine malfunction is 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.
How to proceed in case of a tool break-
age
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:
A tool breakage can be caused by the following:
If a tool breaks, do the following:

1.
Record the error message and error code that is
displayed.
2.
Restart the machine and the CAM computer. 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 mes-
sage and error code readily available.
5.
If you need to remove a blank from the working
chamber, perform an emergency opening of the
working chamber door.
The next regular tool change

the application settings of DentalCNC.
The tool was damaged or worn
n
The tool was put into the wrong tool magazine
n
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
n
("nesting") was not correct.
1.
Open the working chamber door.
2.
Remove all parts of the broken tool from the work-
ing chamber and the collet chuck.
3.
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 cor-
rect position in the tool magazine.
4.
If you manually inserted the tool into the collet
chuck, check if the broken tool corresponds to
