1Attentions
1.1Safety Instructions
1) Please switch to the correct local voltage (115V-230V) before turning on the printer. Be sure
the switch is in the correct position or it will damage the power supply unit (PSU).
2) Be sure all wires are correctly connected before turning on the printer.
3) Don’t touch extruder head or hot bed when printing as they generate high temperature
which may cause burn.
4) Don’t leave the printer unattended when printing.
1.2Factory Test before Delivery
To ensure quality, each printer is tested at the factory. As a result, there may be filament residue
in the extruder head or on the hot bed, but it should not affect normal use. We provide the spare
nozzle in the accessory kit just in case.

5.1Main Frame Assembling
Main frame consists of gantry kit and base, T- shaped plate, spool holder and screws.
1) Assemble the gantry frame and base from bottom with 4 M5x30 screws and 4 spring
washersM5 as shown in picture (5-1).
（Picture 5-1）
2) Fix the gantry frame and base with T-shaped plates. See picture (5-2, 5-3).

3) Assemble filament spool holder and attach to the top of the frame, with 2pcs M3x6 screws
and 2 T- nuts M3, as shown picture (5-4).
（Picture 5-4）
5.2Wire connection
1) Insert Teflon tube into the quick-insert connector of the two extruders as shown in picture
(5-5).

2) Plug extruder wire into molex socket. Be sure plug is firmly seated into socket. See picture
(5-6).
（Picture 5-6）
3) Connect extruder motor wires of E0.See picture (5-7).

Then the extruder wire and the motor extruder wire are fixed into the small hole on the backside
of the screw with the Cable tie to avoid the wire harness touching the model during printing. In
addition, the position the harness fixed needs to reserve the length of the Z-axis at the maximum
height. See picture (5-8).

4) Connect the wires of X axis motor and limit switch. See picture (5-9).
（Picture 5-9）
5) Connect the wires of Y axis limit switch. See picture (5-10).
（Picture 5-10）
6) Connect the Z0 axis motor and the Z0 axis limit switch wire. See picture (5-11).

7) Connect the Z1 axis motor and the Z1 axis limit switch wire. See picture (5-12).
（Picture 5-12）
5.3Check the power input mode
The factory default voltage is 230V, please choose the correct voltage according to your local
voltage standard. See picture (5-13).
Note: Be sure the switch is set for the correct voltage.

5.4Load the filament
Put filament on spool holder, please pay attention to the feeding direction of the filament. See
picture (5-14).
（Picture 5-14）
Filament is bent, therefore it needs to be straightened by your hands and trimmed to make it
easier to insert filament into feeder. Press down the lever handle of the extruder and insert the
filament into the feeding tube until it reaches extruder head. As shown by the arrow in (5-15).
（Picture 5-15）
Please set the target temperature of nozzle about 190-210℃when printing PLA. Control the
extruder feeding on touch screen after the nozzle temperature is stable. See picture

(5-16),(5-17).The extruder will feed automatically until the nozzle material is flowing.
（Picture 5-16）
（Picture 5-17）
Please observe the nozzle , to be sure there is no filament stuck，and that filament is coming out
smoothly. Then stop filament feeding and clear the nozzle with tweezers. See picture (5-18).

6First print
6.1Leveling hot bed
The first layer is the key to a successfully printed model, which would directly affect the quality of
printing model and achieve a good bed adhesion. In order to avoid scratching nozzle and hot bed,
the factory default setting is a little high. Users need to level the hot bed and set the distance
between the nozzle and hot bed before printing. After the first-time bed leveling, users don’t
need to level the bed again. Details as follows:
1) Rough leveling
Please click the “Home”to enter “Leveling”interface on the touch screen. See picture (6-1). If
you click “manual level”, it shows “manual level”interface shown as picture (6-2).
（Picture 6-1）
（Picture 6-2）
Put a piece of leveling paper or A4 paper between hot bed and nozzle, Click the middle "5"
button, and select the appropriate precision (0.05mm/0.5mm) in the lower left corner to adjust
the height deviation value in the Z-axis direction until the distance between the platform and the
nozzle is about one sheet of paper. The thickness can be about 0.1~0.2mm, Slide the paper back
and forth to see if you feel a slight resistance. If yes, it means that extruder head is in the right
place. See picture (6-3). After adjusting the height at position “5”, click “OK”to save current

value.
（Picture 6-3）
Please click the button in order from 1-4, At each corner, use the adjusting nuts under the bed to
set the distance between nozzle and hot bed to about the thickness of a piece of paper. Now
rough leveling is finished. See picture (6-4).
（Picture 6-4）
1) Accurate leveling
If you level hot bed with A4 paper, the first layer might be too high, too low or moderate.
a. Too high: If the distance between nozzle and hot bed is too far, filament will not stick to the
bed well. See picture (6-5).
（Picture 6-5）
b. Too low: If the distance between nozzle and hot bed is too close, it prevents filament from
coming out, causes the extruder gear to click or grind on filament and even worse, it would
scratch nozzle and hot bed. See picture (6-6).

（Picture 6-6）
c. Moderate: Extrude filament properly and evenly. Stick to the hot bed. See picture (6-7).
（Picture 6-7）
In case of too high and too low, please adjust knobs under the hotbed slightly until you achieve
proper height. It may take some trial and error to achieve the best result. An example of good
first layer, see picture (6-8).
（Picture 6-8）
Note:
1) Be sure to adjust the height at center point (position5) on the touch screen, after clicking
“OK” to save its data, you can use then knobs to adjust the hot bed at the 4 corners.
2) When viewed from the above, turning the knobs clockwise, the hot bed will rise, and vice
versa.
3) Avoid the nozzle touching the bed; use a piece of A4 paper. Or it will scratch the bed.
6.2TF card printing
Insert TF card into the slot. See picture (6-9).
