No extrusion of filaments as
printing begins
1) Filaments not loaded in place
2) Extruder planning
3) Filament jamming
1
Insufficient extrusion
1) Incorrect diameter of filaments;
2) Flow rate is too low, please readjust slicing parameters.
2
Holes or gaps in the top
1) Inadequate number of solid layers at the top;
2) Too low infill density;
3) Insufficient extrusion.
3
Wire drawing or draping
1) Too little drawback distance;
2) Slow drawback speed;
3) Extruder temperature too high;
4) Too long idle running distance.

Why does warping occur?
1) Hotbed temperature is too low;
2) Model cooling fan disabled, cooling fan needs to be restarted;
3) Base area of the model is too small, it is required to increase the edges and base.
5
Why does the hotbed not heat up?
1) Check the hotbed heating cable for broken or loose connections and re-enforce or replace with new wiring;
2) Contact after-sales staff to resolve.

What can I do if there is no
response when the memory
card is inserted into the machine?
1) Corrupt print file, re-slice it;
2) The print file is too long, it is better to keep it to 8 letters or less;
3) If the file name is not English/numeric, insert the card into the machine and restart it;
4) Format the storage card;
5) TF card / mainboard card slot is damaged, contact after-sales service to assist in testing.

What can I do about loose X-axis and
Y-axis belts?
Tighten the X-axis and Y-axis adjustment screws with a tool and keep the belt with a certain amount of spring back and
then start printing again.

How to deal with abnormal nozzle
temperatures (too low/too high)?
1) Check nozzle NTC wire for open circuit (too low temperature) / short circuit (too high temperature).
2) Check the nozzle heating block for abnormalities.
3) Replace the nozzle thermistor.
1) Check hotbed NTC wire for open circuit (too low temperature) / short circuit (too high temperature).
2) Check the hotbed heating system for abnormalities.
3) Replace the hotbed thermistor.
