In order to prevent damage to you and others in the process of using, Please be aware of the following:

● Please do not attempt to use the machine in any way undescribed in the instructions to avoid accidental personal injury and property

damage.

● Please do not place this machine near inflammable and explosive materials or high heat sources. Please place this machine in a

ventilated, cool and dust free environment.

● Please do not place the printer on a larger vibrating or other unstable platform. The shaking of the machine will affect the printing

quality.

● Please do not replace the power line of other products during installation. Please use the original power line supplied with the

machine. The working power supply uses 115V/230V AC. The power plug must be plugged into the three holes socket with ground wire

to avoid damage to components or accidents such as fire and electric shock.

● Please do not touch the nozzle and heating bed during the printer working to prevent high temperature burns and personal injury.

● Please do not wear gloves or wrappers when operating the machine in case the movable parts cause entanglement and cutting damage

on the human body parts.

● After printing, please use the remaining temperature of the nozzle to clean up the filament on the it with the help of tools.

Do not touch the nozzle directly with your hands during cleaning to prevent scalding.

● Please often do product maintenance. In the circumstance of power off, please regularly clean the printer body with dry cloth

to wipe away dust and bonded printing materials, foreign objects on guide rails, and lubricating oil is recommended for sliding

parts, screw rods and bearing parts.

● Children under 14 years old or people above 60 years old, please use this machine under the adult people to avoid personal injury.

● Some filaments will produce slight odor but it won't make people feel uncomfortable

● Self-disassembly or modification may cause damage or abnormal performance, and your machine will no longer enjoy warranty service.

● It is recommended to use in a well-ventilated environment. Please cut off the power supply after using.

7.2.2 Machine leveling

1. Auto home operation: Adjust the spring around the heating bed to the tightest ( counterclockwise ), press the rotary button
to enter the main menu, select“Prepare”→“Auto home”, the machine begins to move toward the position of the limit switch until
it stops moving after touching the limit switch.

2.Disable steppers operation: Press the rotary button to enter the main menu, select“Prepare”→“Disable steppers”.

3.Manual leveling：Move the nozzle to the heating bed, and observe the distance between the nozzle and the heating bed from the

front of the machine. If the distance between the nozzle and the four corners of the heating bed is 0.1mm (the thickness of a piece

of A4 paper, A4 paper can pass through the gap and feel slight resistance), leveling is not required. If the distance between the

nozzle and the four corners of the heating bed is greater than or less than 0.1mm, adjust according to step 4.

The distance between the nozzle

and heating bed

Attention: turning the nut counterclockwise is tight

and turning the nut clockwise is loose.

A4 paper can pass through the distance between the

four corners of the heating bed and nozzle, and feel

slight resistance.

4. Adjust the distance: Fine - tuning the "distance" to make its size about 0.1mm meet the printing requirement. Move the nozzle

to the other three corners of the heating bed, and sequentially adjusting the spring compression of the four corners of the heating

bed in one direction (clockwise or counterclockwise), so that an A4 paper (about 0.1mm) can pass through this distance and feel a

slight resistance, and there is no scratch on the platform when moving the extruder.

7.2.3 Load Filament

1． Perheat Machine

Before loading filament, the machine needs to be preheated. The following pictures illustrates PLA filament as an example, and

the operation is as follows.

Operating method: Press the knob→“ Prepare”→“ Preheat PLA”→“Preheat PLA”, the machine starts to perheat ( the main interface

shows that the machine is perheat ).

。

Note: If you want to print with ABS filament, you must select " Preheat ABS" for preheating.

2 Load Filament

Load filament automatically:

1. A roll of PLA filament: Filament specifications: Diameter :1.75mm; Material: PLA ;Printing temperature: 200-230℃;

2.Please press rotary button →“ Prepare”→“ Change filament”, the main interface will display “Heating nozzle Please wait……”,the
interface will display “Wait for start of the filament change” after the nozzle temperature rises to the target temperature →
“Wait for filament unload ” →“Insert filament and press button to continue…” → then please press rotary button;

3. Straighten up the filament (or cut the filament into bevels with plier),then pass the filament through the extruder;

4.Meanwhile the main interface will display “Wait for filament load” →“Wait for filament extrude”,please click “Resume print”

to start printing;

5. If the nozzle has filament outflow, the installation of filament is successful. If the installation of filament is not successful,

please select“Extrude more”to re-load.

Attention: The function of automatic material advance and retreat is carried out according to the steps of material return first and material feed later, when the

first printing has not started installing filament yet, please wait for 1 - 3 minutes. After the interface displays “Insert filament and press button to continue”,

insert filament into the extruder for automatic feeding.

3 Printing

1. After leveling is completed and the filament is installed successfully, press the rotary button to enter the main menu, press

" Print from SD" → " Main" and select the file under " Main" to start first printing.

2. In the process of printing, if you want to pause printing, press the rotary button to enter the main menu, press " Prepare"

→ " Pause print" to pause printing, and press " Resume print" to resume printing.

3. If you want to stop printing during printing, press the rotary button to enter the main menu, press " Prepare" → " Stop print"

to stop printing, press the reset button to resume normal operation of the machine and select to reprint the model.

7.2.4 Remove Model

Please remove the model by hand after printing .

7.2.5 Unload Filament

Automatic unload filament (taking PLA as an example)
Please press rotary button →“ Prepare”→“ Change filament”, the main interface will display “Heating nozzle Please wait……”,wait

for 1-2 mins ,the interface will display“Wait for start of the filament change”after the nozzle temperature rises to the target
temperature →“Wait for filament unload ” ,the machine automatically unload filament ,then pulls out the filament in the vertical
direction and unload the filament.
