SINGLE HEAD - USER MANUAL
12
Select the Extrude menu on the Home screen.
Before extruding, make sure the head is next to the build plate, not pressed into the plate or directly above.
• To extrude filament from the print head, use the down arrow on the touch screen.
• Press and hold the buon to keep the filament extruded of the head.
• Automatic filament feed can also be performed by pressing the Load buon on the boom bar.
By pressing the buon once, the head automatically extrude some filament.
• Filament loading is successful when the melted filament flows out of nozzle evenly and vertically.
Watch out! The freshly spilled molten filament is hot. Avoid contact with spilled filaments or other flammable
materials in the near.
5.4. Unloading the filament
Never remove the filament from the extruder if the extruder is cold!
Always preheat the extruder before removing or changing filaments. Removing the filament from a cold extruder
might damage it!
You don’t have to remove the filament between prints.
• Heat the extruder as described above.
• Make sure the head is next to the build plate, not pressed into the plate or directly above.
• When the extruder reaches the temperature required for the filament, press the down arrow ,
then the up arrow.
• Automatic filament unload can also be performed by pressing the Unload buon.
• When the gears start to retract the filament, you can safely pull out the rest of the filament from the guide tube
and connect the end of the filament to the spool for safe keeping. Now you are ready to load a new filament.
5.5. Changing filaments
• When changing filaments, note that different filaments, such as PLA, ABS, and PET, have different temperature
characteristics.
• If you want to replace a material with a higher temperature (eg. ABS, PETG) with a material with a lower
temperature (PLA), it is need to heat the head to a higher temperature so that the previous material can leave the
head completely before the other filament in its place.
• When changing colors, always push more material out of the head, ensuring that the replaced color is completely
removed from the head. During printing, it may be uncomfortable to notice that the print color is still blending
with the previous color, for example, changing from red filament to white.
