① Plugging of Nozzle by Damaged Part
Using the nozzle management pin with excessive force will damage the part on the moving path or
scratch the part, causing fragments to fall inside the nozzle and plug the nozzle. This will make it
very difficult to unplug the nozzle, and the whole nozzle rod may have to be replaced. For this
reason, you should be careful not to damage the parts.
② Secondary Pollution by Filament Residue Stuck on the Nozzle Management Pin
When the nozzle management pin is used, the melted filament residue will be stuck at the edge of
the nozzle management pin. If you pull out the nozzle management pin while the filament residue is
not sufficiently cooled, the filament residue may be stuck in the entry of the nozzle rod or on the
parts in the path of filament movement inside the extruder, preventing the nozzle management pin
or filament from moving.
In this case, disassemble the detachable extruder part by referring to
Extruder" while the printer is turned off, check for filament residue on the path of filament
movement, and remove the pollutants. If it is difficult to remove the pollutants as they are already
hardened, heat the nozzle management pin and push it. Be careful not to damage any parts that
are vulnerable to heat.
The following figures show a case in which residue was stuck in the entry to the nozzle rod,
preventing the nozzle management pin or filament from moving into it. The printer will work properly
if the pollutants are removed, but if the nozzle management pin is used without removing the
pollutants based on assumption that the nozzle is plugged, the pollutants will continue accumulating
and eventually cause an extruder problem.
Filament Residue
* When disassembling the detachable extruder part while the nozzle is hot, wear gloves to avoid burns.
* Use the nozzle management pin with extreme caution until you are familiar with it.
As improper use of the nozzle management pin can damage the extruder part beyond repair, it is recommended
not to use it if you are not familiar with its use.
e. Cleaning Outside Nozzle
The nozzle is at a high temperature during printing, and often has
melted filament residue stuck on its surface. Filament stuck on the
nozzle surface can adhere to the printed object during printing, creating
stains.
① Heat the nozzle to a level high enough to melt the filament stuck on
the surface. Then, remove the filament residue with the tweezers or
wipe it out with pure cotton cloth.
② If the pollution on the nozzle's surface is severe, cool the nozzle
completely and turn off the printer. Wipe out the pollutant using a rag with a small amount of
acetone. Use the printer only after the acetone is completely vaporized.
③ During the loading or auto tilt process before printing, some filament is taken out through the nozzle
