The filament supply breaks o or there is not enough filament material supplied:
• Check the filament unroller. It must turn easily.
• Check whether the filament material has caught on the filament unroller. The filament hose at the filament roller may have
caught.
• Some filament types do not slide through the filament hose properly. If required, use the alternative filament holder that you can
print from the SD card (file name “Filament_guide.gcode”).
• The
set extruder temperature is too low for the filament material used. The feed knurl slips at the filament material.
• Check whether the feed knurl slips on the motor axis of the extruder motor. The grub screw may have come loose. If the feed
knurl slips in spite of the grub screw being tightened, use a grub screw with a point or slightly file down the motor axis in the
area of the grub screw to reduce slippage.
• The
clamping spring screws at the filament feed are not tightened well enough. Therefore, the drive slips.
• Check that the filament material runs into the extruder from above cleanly. It must be able to run past the extruder motor from
above and into the bore of the extruder without scraping or clamping anywhere. If this is not the case, loosen the nut at the
extruder and the screws at the feed basic part and align the parts so that the filament is cleanly inserted into the extruder.
• The
extruder nozzle is clogged. Heat up the extruder and actuate the manual feed forward and backward several times until
enough filament is extruded.
• Let the extruder cool down to just below the melt temperature specified by the manufacturer for the filament (filament material
must only be viscous anymore) and carefully actuate the manual feed backwards until the filament with contamination has been
removed from the extruder. Cut o the contaminated part of the filament and reinsert it after heating up the extruder again.
Printing stops during the process:
• Check the settings of your computer. It must not switch to standby mode while printing (energy option settings) or simply shut
down (installation of software or software updates during printing).
• If the value measured by the printing sensors at the extruder exceeds a threshold, the printer will automatically switch to pau
-
se mode for reasons of safety. Printing can be started again by pushing the button for continuing printing (play button). If this
happens frequently, the print sensors are installed under tension. In this case, loosen the screws of the print sensors and then
retighten them evenly.
The printed object does not adhere to the heating plate:
• The
temperature of the heating plate is set incorrectly. Experiment with the temperature settings in steps of 5 °C for a prefect
print result.
• When printing problematic objects, it is beneficial to let the heating plate heat up for approx. 15 minutes before printing.
• Check whether the heating (red foam material) adheres cleanly to the ceramics printing plate. It must not come loose (even
partially). If this is the case, the temperature distribution of the heating plate is insucient and the printed objects cannot adhere
well.
• There are residues on the heating plate that prevent adhesion of the object. Rub the heating plate with a soft cloth that is soaked
with a solvent (e.g. acetone).
• The
heating plate has not reached the set temperature yet.
• At PLA printing of small objects with a small footprint, it is recommended to apply the heating plate with cleaning tape or a
slightly structured crepe tape before printing. This increases adhesion of the printed object on the base plate.
The
printed object cannot be removed from the heating plate:
• Wait until the heating plate has cooled down to less than 40 °C.
• Use a painter’s spatula or a knife to remove the object.
Repairs other than those described above should only be carried out by an authorised specialist.
