⇒ Connect the power plug and switch on the printer�
⇒ Select the AXES
⇒ Move the print bed to the lowest position
⇒ Switch off the printer and disconnect the power plug.
⇒ Slide a folded paper towel or lint-free cloth between the threaded rod and the back to protect other
areas of the printer from any overspray that may occur�
⇒ Place a second clean cloth on the print bed to protect the components and the Kapton film from spatter.
⇒ Lubricate the threaded rods and guide rods again as previously described�
⇒ Connect the power plug and switch on the printer�
⇒ Select the AXES
⇒ Adjust the print head and the print bed to the home position
⇒ Switch off the printer and disconnect the power plug.
⇒ Remove excess lubricant or grease underneath the print bed.
⇒ Connect the power plug and switch on the printer�
⇒ Select the AXES
⇒ Move the print bed to the lowest position
⇒ Switch off the printer and disconnect the power plug.
⇒ Remove excess lubricant or grease above the print bed.
11.2.2 Lubrication of the x/y-axis
⇒ Connect the power plug and switch on the printer�
⇒ Select the AXES
⇒ Adjust the print head and the print bed to the home position
⇒ Switch off the printer and disconnect the power plug.
With the motors switched off, the print head can be moved forwards/backwards and left/right by hand.
⇒ Lubricate the x and y-axis guide rods with an oiled cloth.
Do not spray lubricant or oil into the unit from above!
⇒ If the print head moves easily in all directions, lubrication is sufficient.
11.3 Unblocking the extruder
A blocked extruder is the most common problem with any 3D filament printer and cannot be prevented
entirely�
When loading/unloading the filament, a blockage can often be avoided by waiting until the extruder has
reached the temperature corresponding to the filament.
It is especially important to remove old filament residue between using different filaments.
Different filament properties (even printing the same material in a different color) can cause block-
ages due to inconsistencies.
Do not switch off the SIMPLEX 3D filament printer until the nozzles have cooled down (< 60°C).
(Note: Extruder fan shuts down at < 60°C). If you switch off the SIMPLEX 3D filament printer when
the extruder is hot, the temperature can spread from the extruder into the heatbreak, melt the fila-
ment and lead to clogging after the extruder has cooled..
You can clear a blockage in the extruder with the smallest of the Allen keys provided.
Caution! Danger of burns!
The blockage must be cleared while the print head / extruder is hot.
Wear protective gloves!
⇒ If you have not already done so, remove the filament (see Chap. 7.6).
⇒ Move the lever at the top of the extruder to the left.
⇒ Heat the extruder to 250 °C.
⇒ Press out excess filament by inserting the Allen key into the opening. Ensure
that you do this as necessary but not forcefully as this would damage the ma-
chine�
If the blockage cannot be cleared, you must replace the nozzle (see the following
chapter).
