Solution
We promise that the Cura installation file provided in the
OverLord SD Card does not contain any harmful files
that may destroy your computer or files. Please add trust
for Cura installation file.
Poor contact of nozzle heating module. Check its wire
contact and restart 3D printer. Contact
support@dreammaker.cc if it appears frequently.
Run "Level—Auto" in main menu to calibrate and
remember to paint 3 layers of glue on build plate and
wait glue drying before printing.
Add a little lubricating oil to the 6 rods of OverLord.
Check the tension in the 3 belts.
Follow the steps in "3.4 Fasten the belt".
Poor contact of temperature sensor in nozzle. Check its
wire contact and restart 3D printer. Contact
support@dreammaker.cc if it appears frequently.
Poor contact of temperature sensor on build plate, please
contact support@dreammaker.cc.
Broken or poor contact of temperature sensor in nozzle,
please contact support@dreammaker.cc.
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.
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".
Follow the steps in "3.2 Clean the broken filament inside
extruder" or "3.3 Clean the broken filament inside
filament feeding tube"
