Three: Assembly
3.1 Machine Assembly
Please make sure the machine is not damaged during shipping. If there is
any problem, contact the seller as soon as possible. If the machine is in
good condition, and no tools or supplies are missing, feel free to start
installing your printer.
Step one: place the aluminum extrusion (2) such that they are facing
toward the front of the printer (1), use the bolts from bag A1 (black
M5*25 bolt) (3) to fasten both aluminum extrusions.
Step two: check that the aluminum extrusion (1) is secured, make sure (2)
and (3) are orientated correctly according to the picture.
Step three: twist couplings of both z-axis steppers at the same time so
that the x-axis rail can slide in smoothly.
Step four: make sure the aluminum extrusion is facing the front (similar to
step one), use the hardware in bag A1 (black M5*25 bolts, M5 washers)
to secure the top aluminum extrusion.

Step five: extruder stepper installation. Make sure you place the stepper
(1) with the correct orientation as highlighted with the red box. Four
threaded holes are facing the aluminum plate (2). Use then bag of
hardware labeled as A2 (black M3*10 bolt) (3). Tighten the stepper as
shown.
Step six: find the x-axis slider (1), use bag A3 hardware (black M4*8 bolt),
and tighten up extruder module (2).
Step seven: place the extruder wiring harness on the right, use the bolts
in bag A4 to secure the cable chain from left side (2) to right side (3), this
way is easier.

Step eight: slightly loosen the nuts near plate (1) and filament holder (2),
fasten on the aluminum extrusion.
Step nine: slightly loosen the nuts near the T shape plate (1), fasten the
plate on the aluminum extrusion.
Note: refer to picture 10 about how to assemble parts on the aluminum
extrusion.

3.2 Machine Wiring
Step one: screw the golden one-touch fitting (1) to the extruder and
connect the filament sensor cable (2) to the extruder.
Step two: connect the extruder cable E0 (1) to the extruder, connect x-
axis stepper cable and limit switch cable to (2) and (3).
Step three: connect the circular connector (1) on to the correct location
showed in the picture, align the connector before plugging in, then fasten
the connector.

Step four: connect Z axis endstop cable (1) with endstop from inner side.
Step five: plug in the extruder cable (1).
Step six: wire the cable to the z-axis stepper motors (1) (2).

Notes:
Double check your connection.
Use a scale/ruler to make sure (1) and (2) are at the same height.
Congratulations! The installation is finished. Start your 3D printing now!

4.1 Auto Leveling
Plug in the power cord (1), remove the film pressure sensor, one end
connects to the nozzle and the other connect to the side of the unit as
shown in the picture (2); click “more” on the main interface, press “auto
leveling” and confirm, and you will see “leveling is completed” after the
print bed is leveled. Note: make sure your print environment is less than
45 degree Celsius so that the film pressure sensor can work properly,
you don’t need to redo auto leveling for future print.

Note: If you are not satisfied with the result from auto calibration, you
can enter into “Baby step” interface (1) , and then adjust the nozzle
height by pressing “+” or “-” to adjust the nozzle height during print. If the
nozzle is too close to the print bed, press “+”, otherwise, press “-”. Long
press “+” or “-“ to speed up the process, and this technic is also
applicable to increase or decrease nozzle temperature.

4.2 Auto Feeding
Unbox the filament, cut the end of the filament to a 45 degrees angle and
make it straight (1). Press “More” on the main interface (2), then press
“change filament” (3). Press “A” to heat up the nozzle (4). After finished
heating, feed the filament to the extruder(5), and then press “A” again (4).
Note: a. Please make sure there is no filament inside Teflon tube before
you use auto feeding function. If there is, please heat up nozzle and use
tool to squeeze filament out beforehand.
b. It is normal to hear "click" sound from extruder when filament is
extruding from nozzle, just wait for "Bi" sound, it means auto feeding
finished.
