II. NOTICES
Please read all the instructions in the manual and familiarize yourself with the Ender-3 V2 3D Printer User Manual before setting-up
and using your 3D printer
PLEASE FOLLOW ALL THE SAFETY WARNINGS AND NOTICES.
Failure to comply with the warnings and instructions may result in individual injury, inferior results and printer damage.
1. Work Environment and Safety
Keep your workplace tidy. Do not operate the 3D Printer in the presence of flammable liquids, gas or dust.
The printer should be placed out of the reach of children or pets.
Only operate your 3D printer in room temperatures of 5-30℃ with an ambient humidity between 20%-70%
2. Electrical Safety
● Always use a properly grounded outlet and the cable provided to prevent damage to your printer.
● Please unplug the 3D Printer if it will not be in use for a while.
● Do not use outdoors, indoor use only.
● Always keep the printer in a dry environment and out of direct sunlight.
● Do not use the 3D Printer during thunderstorms.
3. Personal Safety
● Do keep your hair, clothing and gloves away from moving parts.
● Do not operate the 3D Printer while you are tired or under the influence of drugs, alcohol or medication.
● Parts of the 3D printer will get very hot during use, Do not touch the nozzle, hot end assembly or the build plate when the printer
is warming up, printing or cooling down.
● Ensure you keep others, especially children and pets away from the printer.

05
4. CAUTION!
● Do not leave the 3D Printer unattended.
● Do not make any modifications to the printer other than any approved SainSmart upgrades.
● When removing a model be careful not to use excessive force.
● The 3D printer must only be operated in a well ventilated area, noxious gasses can be released.
● Do not exceed the maximum print temperature of your printer or the filament you are using.
● When loading or unloading filament make sure the printer nozzle is well clear of the build plate (>50mm).
5. Filament and storage
● Follow any recommendations of your filament manufacturer.
● Do not use your printer to make anything that will come into contact with food unless specifically allowed by the filament manufacturer.
● Filament should be stored in clean and dry conditions. Filaments will absorb moisture and degrade over time if not kept dry.
● Do not open the filament from it’s sealed package until it is needed.

tensioner base making the alignment is as shown in the picture above.
● Screw the tensioning knob back into place by couple of turns.
● Attach the Tensioner base to the profile Z Axis Roller Bracket assembly with a M4X16 screw on one side
and the countersunk screw (in the Tensioner block bag) on the other, both these screws use the same
threaded hole in the profile.
● Secure the ends of the drive belt by sliding the belt into the slots in the Nozzle assembly as in the picture
above.

● Turn the X-axis and Y-axis tensioner
knobs to adjust the belt tension.
● The belts should be taught but not over-
tight or too slack. When you press down
the drive belt, you should feel some
spring in the belt.
● If the belts are too lose they can slip
during printing ruining the result.
● If the belts are too tight they will over
stress the pulleys and motors or even
break.
● Place the lower V rollers into the grooves on the outside of the Z profiles.
● Locate the lead screw in the Brass nut on the XE Assembly and turn by hand to
screw the gantry down while guiding the other V rollers into the Z profile grooves.
● Adjust the tension of the X and Y axes drive belts as shown above.

7. Install the Gantry Profile and Display Assembly
● Secure the Gantry profile onto the upper end of the gantry with four hexagon socket head
cap screws M5x25 and tighten securely:
● Unclip the display from the bracket, slacken the screws pre-installed on the bracket and
insert the T nuts into the base profile.
● Tighten the bolts making sure the T nuts are turning to engage with the base profile.
● The display can be moved forwards and backwards to suit your preference then tighten
the bolts.
● Connect the ribbon cable to the display screen and clip it back onto the bracket.

VI. CONTROLING THE PRINTER
1. Display and Controls
At the base of the screen there is a single knob, this has two functions:
1. As the knob is rotated it will move, highlighting whatever option is selected at the time.
2. The knob is also a switch, by Tapping it once, you will go into the menu option that is
highlighted at the time the button is pressed.
At the bottom of the screen is a status bar which displays the current and target temperature
for the nozzle and bed temperatures,
Print speed override value and the current distance of the Z axis above the home position.
From the main screen four options are available:
Print
This allows you to select a file from the SD card to print. Once selected, the file is loaded and
the print starts while displaying print details and progress.
Prepare
This menu allows you a number of options to get your printer ready for printing, such as manually moving the axes, auto homing the
printer (returning the Nozzle to the starting position for any print), preheating the bed and nozzle to preset values, putting the printer
in cooldown mode and selecting the display language.
Control
This allows manual selection of the fan speed, nozzle and bed temperatures and the changing of some of the default values for
motion and temperatures.
Info
Shows some information such as the current firmware version.
Each menu or submenu has a Back option at the top, to return to the previous menu Highlight this and Tap.
