How to reduce connecting strands?
Try larger retraction length and speed in
“Setting—Retraction setting”. Lower nozzle temperature
to 210~220℃ during printing and set printing speed to
80~110mm/s. Get rid of connecting strands and refine
the model by sandpaper or heating method.
Not enough material coming out of
nozzle during printing;
Abnormal porous structure on print
surface;
Nozzle seems blocked.
Confirm the setting in Cura is correct;
Check whether extruder is extruding material properly.
If it is not, select “Material” and reload filament once
more to see is there any material coming out of nozzle
after loading.
If the material doesn’t come out of nozzle, follow the
steps in “3.1 clean the nozzle”.
Filament is broken inside machine;
The function of “Material” (auto
reject/feed filament) doesn’t work.
Follow the steps in “3.2 Clean the broken filament inside
