Method 3:
If the procedure described above has not led to success, heat up the extruder to the printing temperature (PLA = 230 °C, ABS = 270 °C).
Have the printer extrude some filament when the temperature is reached.
Then let the extruder cool off. For PLA to approx. 90-110 °C and for ABS to approx. 110-130 °C. The proper temperature depends greatly on
the filament used. You may need to repeat this process several times with different temperatures.
When the temperature is reached, switch off the printer and pull the filament quickly out upwards by hand and in one go. At the end, there must
be a small cone that corresponds to the inner shape of the nozzle.
This method can also be used to remove all filament from the extruder, e.g. for a heat bed scan.
It is recommended to also wipe the nozzle a few times, e.g. with a paper towel, while cooling off.
Cleaning the printing plate
Caution: Danger of burns. Let the printing plate cool off before cleaning.
Clean and degrease the printing plate thoroughly with a soft rag and some acetone after each print.
c) Fuse replacement
If you have to replace the fuse, ensure that you only use fuses of the specified type and rated current (see chapter 25. "Technical data") as a
replacement.
Never repair fuses or bridge the fuse holder.
• Unplug the mains plug from the mains socket and disconnect the low-voltage line from the low power device combination socket at the rear
of the device.
• Using a suitable screwdriver to push the fuse holder out of the low power device combination socket carefully.
• Remove the defective fuse and replace it by a new fuse of the indicated type.
• Carefully push the fuse holder with the new fuse back into the low power device combination socket at the device.
• After this, you can reconnect the device to the mains voltage and take it into operation.
