function of the limit stopper is normal, in particular pay attention to the
debugging of Z-axis’ limit stopper. Click Function Key to choose Prepare, then
choose Auto home and click confirm to check each stopper. Adjust the nut of the
long screw on the left of Q assembly, adjust the lowest position of Z-axis moves
down to ensure the gap between the nozzle and the printing bed.
3. Cut off the power and put the square glass with masking tape on top of the red
heating bed, fix it with the 4 Dovetail clamps, please note the position of the
dovetail clamps should not affect the functions of the nozzle and among others.
Move the nozzle to check if the printing bed is parallel with the nozzle, and keep a
proper gap. Then power on, check the original position of the nozzle and the gap
between nozzle and the printing bed, make sure there is proper gap.
Page 18

4.Check if the threaded rod of the Z-axis is deformed, make sure the gap between
axis couplings of motors of A4 & A5 assemblies and the bed is 3mm.Try to keep
the shaft line of Z-axis threaded rod and the output shaft of motor in the same
straight line. Keep the horizontal distance of the upper and bottom sides of Z-axis
threaded rod is equal. Adjust these distance and gaps until no noise occur when
motor is moving on working.
5. The bundling of cables should not affect the moving space and functions of
each parts. Adjust the heating temperature of the printing head according to
practical conditions.
6.The sounds of rotational motors and cooling fans are normal.
7.Heating tube damage(Suitable for all FDM 3D printers): When stop using the
printer or need to clean the nozzle, use spanner to clamp the square aluminum
block and unscrewing the nozzle. Make sure the square aluminum block can not

Common Problems and Solutions
1.Shifted layers
(A).Screws are firmed but still shift
a.Check the pulleys make sure they are parallel
b.Check if belts are loose, tighten them
B).Check drive on the mother board. Exchange drive boards of X Y Z for testing
C).Check elements such as bearing on the Q module,make sure they are firm
2. Screen shown as below means temperature sensor or temperature wire is not
Page 27
27
connected well
27°is temperature of nozzle, 0°is setting temperature for nozzle
0° is temperature of platform, 0°is setting temperature of platform
Check if connection of the wires of platform or mother board is connected well. If
both temperature 0°are not changed, it means temperature is not setting yet or
mother board broken.
3.X-axis moves abnormally or shaking
(a). Check the bearing of the belts and see if they are damage or deformation
(b). Check wires of the X-axis motor, if any problem change the wires
4. a.The LCD screen on but without display
b.The machine restart suddenly after switch on
c.The motor can not stop after touch the limit switch
Check connection of the sensor’s wires, if connection is no problem, there will be
problem of the wires, change the wires.
5.The fan is not working.
Make sure the temperature is above 50°C, if fan is not rotated,check the interface
and reconnect it. Or test by battery, if still not rotated, change the fan.
The default rotating speed of the fan is 255, if is 0,please adjust it to 255.
6. Motors can not rotate, check connection wires of the motors, exchange the
Page 28
28
wires for testing, if motor rotating, change the wire, if not ,change drive board of
the motor.
7.Filament is blocked:
a).filament is too thick
b).dismantle the nozzle.
8.Sliding: filament is too thin,cut part of filament
9. Nozzle is blocked: heating tube is blocked by filaments, dismantle heating part
and heat it to 220℃, then get filaments out with tweezers.
10. Abnormal temperature: thermocouple is damaged,change the thermocouple
11.Printing offset: Screw is loosened, check and tighten screw
12. Sample edge deformations: bed is too high, adjust the bed height
13. Filament is glued onto nozzle: supporting material are pulled by nozzle,reset
the parameters
14. Filament does not flow out: model is faulted,transform the model into code
and set parameters after model being corrected.
15.Driver or software cannot be installed: wrong system configuration, re-install
the system
16. print samples cannot be glued on platform: too large gap between nozzle and
bed,readjust the bed
17.Click any mode when printer is powered, the motor does not move,change a
new printer identifier.
18.Tape cannot be moved off: heat the platform to 20℃ or 30℃ and take off the
Page 29
29
tape completely.
19.When finish printing or need to change filament during printing. Please choose
the function of discharge, do not pull out the filament by force,the way will deform
the filament which is hot in the heating tube,thus will jam or damage the extrusion
gear.
20.The wood fix Y-axis is easy fracture, if it is broken, request for A13 wood for
replacement.
21.Z-axis can not move up and down or move very slowly, please operate Z-axis
in controlling setting. Otherwise exchange the motor wires or drive board of the
motors for testing.
22.Platform glass damaged. Do not press the platform glass heavily. After finish
printing, use the blade to prize up the model carefully and take it down. Do not
pull it up directly, this way will damage the platform glass easily.
For the model which wasn’t taken down on time. As after finish printing, the
printer will be cooling down, temperature of the platform will turn down to normal,
thus the model will be stick on the platform and hardly to take down, in this
situation, heating the platform up to 100°C, then it can be taken down easily.
23.LCD screen is not on.
(a). Check and confirm if connection wires of the screen and mother board are
connected correctly.
(b). Check if the white switch on the blue controller on the back of the screen is
loose, firm it with screw and see if the screen is on.
