3.1 clean your nozzle
Why:
The nozzle could be blocked by dirt, carbonized material or changing material of different
properties. Sometimes it happens gradually: first, porous structures start to appear on surface of
print object, then it becomes worse and worse, till there is nothing come out of the nozzle. If you
do not clean your nozzle when the above signs start to appear, the quality of print will become
worse and worse. The best way to protect nozzle from blocking is to use filament of good quality
and do not change it often.
Porous structures on print object surface
How:
1. Switch off the printer.
2. Find the nozzle module, loosen the black plastic spiral, unscrew the fastening screws and
disassemble the black shield together with the PCB of nozzle module. Remember do not get lost
the 4 washers.
