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.
1.3 Risk statement
1) Before color mixing or monochrome printing, make sure that there is the filament in the
feeding tube on both sides of the extruder head to prevent back flushing of the molten
filament inside the extruder head, resulting in clogging.
2) Make sure there is filament in feeding tubes on the both side of extruder head even using a
single-sided extruder for monochrome printing, moreover the filament in the other feeding
tube cannot be pulled out during the printing process.
3) Please do not disassemble the printer without permission. If there is any problem, please
contact the after-sales service.

3) Secure the three sets of remote extruders to the back side of the gantry top profile and
tighten the screws as shown in picture (5-4).
（Picture 5-4）
4) Please place the filament on the roll of filament holder kit first, and then fix the kit to the
top profile of the gantry frame with 2 M3 * 6 screws and 2 T-nuts M3. If you need to replace
the filament roll, just remove the corresponding filament holder kit. A total of 3 sets of
filament holder kits need to be assembled, as shown picture (5-5).

5.2Wire connection
1) Insert three Teflon tubes into the quick-insert connector of the three extruders as shown in
picture (5-6).
（Picture 5-6）
2) Plug extruder wire into molex socket. Be sure plug is firmly seated into socket. See picture
(5-7).

3) Connect the E0, E1, and E2 extruder motor wires .See picture (5-8).
（Picture 5-8）
Then the extruder wires and the extruder motor wires are fixed into the small hole on the
backside of the screw with the Cable tie to avoid the wires harness touching the model during
printing. In addition, the position the harness fixed needs to be reserved the length of the Z-axis
at the maximum height. See picture (5-9).

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 (5-14).
Note: Be sure the switch is set for the correct voltage.
（Picture 5-14）
5.4Load the filament
Put filament on spool holder, please pay attention to the feeding direction of the filament. See
picture (5-15).
（Picture 5-15）
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. Extruder E0, E1, E2 with arrow
shown in picture (5-16).
（Picture 5-16）
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
(5-17),(5-18).The extruder will feed automatically until the nozzle material is flowing. Please
select extruder E0, E1, E2 in turn.
（Picture 5-17）

Please observe the nozzle , to be sure there is no filament stuck，and that filament is coming out
smoothly and switching the colors of filament smoothly. Then stop filament feeding and clear the
nozzle with tweezers. See picture (5-19).

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 (Slide the
paper back and forth to see if you feel a slight resistance). 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）

Shenzhen Getech Technology Co.,Ltd
19
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).
