10.10 Nozzle cleaning
Do not touch the nozzle during these procedures - it’s very hot and it may cause burns!
To make cleaning easier, move the print head all the way up in the
LCD menu - Settings - Move
axis - Move Z axis.
You will gain better access to the hotend.
The filament is being extruded just a little
If the filament doesn’t go through the extruder smoothly and only a small volume is coming out, first
check if the extruder fan is working properly and that the
temperature is set correctly (PLA 210 °C;
ASA 260 °C, PETG 240 °C).
Also, check that the filament was correctly loaded into the extruder.
If that is not the case. Follow the instructions below:
1.
Heat the nozzle according to the filament you want to print from. Load the filament and
push
an acupuncture needle
(bundled with the printer) or a thin wire (0.3-0.35 mm)
into the nozzle
from below
- between 1 and 2 cm deep. Wearing gloves is recommended - melted material
may pour out unexpectedly.
2.
Choose
Load filament
option from the
LCD menu
and check if the filament is extruded properly.
3.
Push the acupuncture needle or wire into the nozzle again and repeat these steps several times.
When the filament is extruded properly, the nozzle is clear.
The filament is not pushed out of the nozzle
If you can see the filament passing through the main PTFE tube, yet none of the filament is going
through the nozzle, then most likely, your hotend got clogged. In order to fully clear it, please follow
these instructions:
1.
Heat up the nozzle to 250 °C for PLA or 270°C for ABS jams.
2.
Wait 3-5 minutes and then go to
LCD Menu - Load filament.
If you cleared the clog and the
filament went through, simply lower the temperature to normal and re-do load filament again.
