⇒ Insert the largest Allen key into the bore hole in the heater car-
tridge and unscrew the heatbreak�
⇒ Then unscrew the nozzle, countering it again with the Allen key�
11.4.1 Attaching the nozzle
⇒ Screw in the new nozzle and heatbreak, countering it again
with the Allen key�
⇒ Clean the heatbreak and lubricate it with a conductive paste
(see scope of delivery).
Recommended:
• Halnziye HY810 paste
- Thermal conductivity:
- Thermal resistance:
- Operating temperature:
⇒ Slide the nozzle unit into the heatsink from underneath and
tighten the two screws again�
⇒ For the rest of the assembly, proceed in reverse order as previously described.
11.5 Applying a new Kapton film
The Kapton film of the print bed wears out over time or can be damaged by the nozzle due to in-
correct calibration or removal of the printed models.
Replacing the Kapton film is important to maximize print quality when the old Kapton film has problems or
is damaged�
⇒ Select the AXES
⇒ Move the print bed into a position that facilitates removal of the build plate.
⇒ Fold the two metal clasps on the front of the print bed to the side.
⇒ Lift the build plate slightly at the front and pull it forwards out of the rear metal clasps�
⇒ Remove the old Kapton film by peeling it off the glass plate.
⇒ Clean the surface of the build plate with acetone�
⇒ Remove the plastic protective film (save for future use) from the sticky side of the new Kapton film.
⇒ Apply a little window cleaning fluid to the build plate and to the sticky side of the Kapton film so that you
can position the Kapton film properly on the build plate.
⇒ Place the Kapton film on the build plate so that the distance to the opposite sides is approximately the
same�
⇒ Once the positioning is correct, place the protective film (removed at the beginning) on t he new Kapton
film to avoid scratches and damage during the following operation.
⇒ Squeeze out the excess liquid between the build plate and the Kapton film with a thin but firm object
(e.g., with a used credit card).
⇒ Start in the center of the build plate and move horizontally and vertically� Once all the liquid has been
squeezed out and the Kapton film has been properly applied, set the build plate aside to dry.
⇒ Leave the build plate with the new Kapton film for a day before use.
⇒ Cut off any overhanging film flush using a knife.
To insert the build plate into the print bed:
⇒ Place the build plate on the print bed�
⇒ Slide the build plate towards the back into the metal clasps�
⇒ Close the two metal clasps on the front of the print bed�
