Troubleshooting
DentalCNC interrupts the job execution and dis-
a
plays that the air pressure is too low.
You can resolve this problem while the job execution
b
is interrupted. DentalCNC continues the job as soon as
the air pressure is sufficient again.
Ø
Is the service unit properly set?
M Set the air pressure at the service unit to a value be-
tween 6 bar (90 psi) and 8 bar (120 psi) (recommend-
ed: 7 bar (100 psi)).

Ø
Is the error caused by the external compressed air
supply?
M1. Close the external compressed air supply valve.
M2. Check if all pneumatic hoses are properly seated in
their connections and are undamaged.
M3. Check if your compressor is switched on and set cor-
rectly.
M4. Check if all effected valves of your compressed air sys-
tem are open.
Ø
Does the air pressure fluctuate significantly according
to the service unit so that the job execution is inter-
rupted and continued frequently?
M1. Check if your compressor can permanently generate at
least 6 bar (90 psi) air pressure with a volume flow of
50 l/min (1.8 cfm).
Not every compressor is designed for commercial use
b
with dental machines.
M2. If necessary, replace your compressor with one that
meets the above recommendations.

Documentation of the suction device
I have exchanged the tool magazine inserts and
now there are no holes for the tools anymore.
Tool magazine inserts are delivered without drilled
holes for tools. You drill them with the Machine.
Drill the tool positions into the inserts with DentalCNC.
