A : Check if the temperature sensor falls out of the heating block. Refer to Section 4.4.
Q : Able to heat nozzle, but unable
to reach target temperature
Q : Abnormal nozzle temperature,
displays “0” other than ambient
temperature
Q : Unable to preheat the nozzle
A : 1. Check if the extruder motors are working normally.
2. Refer to Section 4.4 for maintenance.
3. Please do not mix-use filament of different type or brand.
Q : Unable to extrude filament
normally
4.3 3D Print Functional Module Failure
A : 1. Unplug the cables, U disk and microSD card orderly, restart the machine to decide if the failure
is caused by corresponding faulty component.
2. Update the mainboard firmware.
3. Update the touch pad firmware.
Q : Unable to exit “starting...”
interface after power up
A : Unplug the cables, U disk and microSD card orderly, restart the machine to decide if the failure is
caused by corresponding faulty component.
A : 1. Unplug the cables, U disk and microSD card orderly, restart the machine to decide if the failure
is caused by corresponding faulty component.
2. If the issue is solved after unpluging the heating rod socket, please check if failure is caused by
short-circuit of heating rod cables. Refer to Section 4.4 for maintenance.
A : Check if the heating rod and heated bed are reversely connected.
Q : Buzzer on after starting,
the machine shutdown a few
seconds later automatically
A : 1. Check and make sure the cables are in good connection.
2. Check crossly(i.e. connect X-axis linear actuator to Y port and Connect Y-axis linear actuator to X port
and Connect) to decide if the failure is caused by the faulty linear actuator or control board.
A : 1. Check if temperature sensor cable is connecting to the correct socket properly. Refer to Section 4.4.
2. Use the spare temperature sensor to decide if the failure is caused by faulty temperature sensor.
Refer to Section 4.4 for maintenance.
A : 1. Check if nozzle temperature displays normally.
2. Check if the heating rod cable is connecting to the correct socket properly. Refer to Section 4.4.
3. Functional module is damaged.
4. Heating rod is damaged.
Q : Unable to start the machine,
auto shutdown or restart
Q : Auto shutdown after pressing
nozzle heating button
Q : Movement of X/Y/Z linear
actuator is abnormal
A : Carbonized material will accumulate in the nozzle after long time printing. To keep the print head in good
condition, we suggest you clean the nozzle after every 1kg filament printing by applying the cold-pull
method: Remove all three quick pipe connectors from the print head, then heat nozzle to 200~220
℃
,
use your hands to feed filaments into the three channels simultaneously until all three filaments flows out
for 5~15s. Stop heating and wait until nozzle temperature drops to 90~100
℃
, then pull out the filaments,
in this way, the carbonized material may be pulled out together. Remove the bulged end and be ready for
the next cold pull.You may need to perform the cold-pull 4~5 times to get the nozzle fully cleaned.
Q : Under extrusion, too little
filament is extruded during
printing
