Cleaning Of Detachable Extruder And Nozzle - Cubicon Single Operation Manual

6.8.2. Cleaning of Detachable Extruder and Nozzle

The extruder nozzle is positioned at the bottom of the detachable extruder part, and pushes out the
melted filament to form the printed object.
After extended use, the printing condition may become poor due to filament residue or external
pollutants, and in severe cases the nozzle may even become plugged, requiring the replacement of the
nozzle.
You need to clean the nozzle regularly to use it for an extended period of time.
a. Maintaining the Nozzle in Clean Condition for a Long Period of Time
If a nozzle becomes plugged, it is likely to continue causing problems until it is replaced. As it is
possible to keep a nozzle clean for a long time through good management, take note of the following
tips.
① Check the nozzle's condition regularly and clean it.
② If the filament discharge condition is anomalous, such as the filament coming out of the nozzle
during printing being too thin or not uniform, stop printing and clean the nozzle. This should be
performed immediately, as a pollutant inside the nozzle can deteriorate the nozzle's condition at any
time.
③ Sufficiently clean the nozzle if possible when the filament is replaced.
be cleaned when a different type of filament with different printing temperature condition is being
replaced, such as ABS or PLA.
It is recommended that the detachable extruder part specific to the filament be used when a
filament with a different printing temperature is used.
④ Generally, a filament pollutes the nozzle more severely if it has a color (incl. white) or has a darker
color. Clean the nozzle more often when you use such filaments.
⑤ A filament will have properties that are different from its initial properties if it has been melted once
and hardened. In other words, if heating/cooling is repeated without the filament inside the nozzle
being discharged, the filament will become the pollutant, and will not be able to be used for printing.
Therefore, make sure that the heating/cooling is not repeated without the filament nozzle being
discharged.
⑥ The filament will begin to be polluted by moisture and dust as soon as it is removed from the
vacuum pack. Start using the filament as soon as possible after it is opened, as the nozzle will
become plugged when an excess of pollutants is accumulated.
b. Cleaning Inside Nozzle Using Cleaning Loading
① Pull out the filament sufficiently by selecting {Prepare > Load Filament} from the functional menu.
Loading will stop automatically after a certain amount of filament is discharged if the user does not
stop it.
Set the temperature of load filament to be the same as the filament temperature.
② If the print condition is not satisfactory after step ①, set the temperature of Load Filament to a
higher temperature than the filament temperature and repeat step ①.
* Do not raise the temperature more than 10% higher than the normal filament discharge temperature. This
may change the filament property and intensify nozzle plugging.
* Do not perform "step b" if the filament does not come out of the nozzle or is too thin. This may split the
filament or twist the filament inside the fixed extruder part and cause a problem.
c. Cleaning Inside the Nozzle Using Nozzle Management Pin
If you cannot improve the printing quality with loading or cannot load the filament, it is likely that residue
has been left in the nozzle or that nozzle hole plugging is too severe for the pollutant to be removed by
loading only. In that case, clean inside the nozzle with the enclosed nozzle management pin, in
consideration of following:
Detachable Extruder should be cleaned after separation from the fixed Extruder.
