HOW DOES IT WORK

--------------------------------------------------------------------------------------------------------------------------------------------

The WANHAO Duplicator 4/4x makes solid, three-dimensional objects out of melted
WANHAO PLA/ABS Filament. Your 3D design files are translated into instructions for
the WANHAO Duplicator 4/4X and sent to the machine via USB cable or SD Card.
Then the WANHAO Duplicator 4/4X heats the WANHAO PLA Filament and squeezes
it out through a nozzle to make a solid object layer by layer. This method is called
Fused Filament Fabrication [FFF].

2. Navigate to Utility and press OK.

3. Choose this item to start platform leveling.

Why Leveling Is Important

!

•

If the build platform is too far from the extruder nozzle, or if one part of
the plate is farther away from the nozzle than another part, your builds
might not stick to the build plate.

•

If the build platform is too close to the extruder nozzle, the build plate
can block the Printer PLA Filament from extruding from the nozzle.
This can also scratch the build plate.

•

Leveling your build plate often will help ensure that objects adhere well

to the plate.

* How to Level the Build Plate

To level the build plate, you must adjust the four knobs which under the build
platform. These four knobs lower and raise the build plate.

• Tightening the knobs [turning them to the right] moves the build plate away

from the extruder nozzle.

• Loosening the knobs [turning them to the left] moves the build plate closer to

the extruder nozzle.

• The distance between the extruder nozzle and the build plate should be about

the thickness of the A4 paper.

--------------------------------------------------------------------------------------------------------------------------------------------

2. Adjust the Knobs as Directed

The script will prompt you to adjust the
knobs individually. As you adjust each
knob, make sure the A4 Paper just slides
between the nozzle and build plate.
You should feel some friction on the A4
Paper but still be able to easily pass the
Paper between the plate and the extruder
nozzle without tearing or damaging the
paper.

3. Adjust Each Knob Again

The script will prompt you to adjust each
knob again. This allows for fine tuning.
This time, the A4 Paper should slide between
the build plate and nozzle with more friction.

4. Confirm your Adjustment

After the second set of adjustments, the
nozzle will move to the center of the build
plate. Confirm that the the A4 Paper slides
between the nozzle and plate with a moderate
amount of friction.

attaches to the top of the extruder.
You must remove the filament guide
tube from the extruder. To remove the
tube, gently pull it out of the hole in
the top of the extruder.

2. Feed the Filament Through the Filament Guide Tube

Free the end of the PLA Filament
from the filament spool. With a pair
of scissors, cut a clean edge. Feed
the end of the PLA Filament into the
end of the guide tube where it
attaches to the back of the Printer.
Feed the PLA Filament through the
guide tube until it emerges from
the other end of the tube.

NOTE: To avoid filament jams,
ensure that the PLA Filament
feeds from the bottom of the
spool toward the top of the spool.
Put the right filament iinto the
left filament tube. Put the left
filament into the right filament
tube.

5. Push the Filament into the Extruder

To use one hand to push the loading
button down and Take the end of the PLA
Filament closest to the extruder and firmly
push it into the hole in the top of the
extruder.Ensure that the filament goes
into the center of the opening and doesn’t
get caught at the edge of the opening.

Maintain pressure on the filament and
continue pushing it into the opening.
After about five seconds, you should
begin to feel the motor pulling in the
filament. Maintain pressure for another
five seconds and then let go.

6. Stop Extrusion

Watch the extruder nozzle. After a few
moments, you should see a thin string of
the PLA Filament that you loaded come
out of the nozzle. Press the OK button to
stop extrusion.

NOTE: Don’t be surprised if the
filament that initially comes out of the
nozzle is not the color you expected.
There’s probably some filament inside
the extruder left over from our testing
process in factory. Wait until you see the
color that you loaded come out of the
nozzle before you press the OK button.

PROBLEM

--------------------------------------------------------------------------------

1. Can't load WanHao
Filament into the
extruder

SOLUTION

Make a fresh cut at the end of the Filament.
Cut the Filament at an angle—a narrow tip
will help with loading.

Use more force when pushing the Filament into
the extruder. Grasp the filament firmly and push it
into the middle of the hole on top of the extruder.

Ensure that you insert the Filament straight down
into the extruder, not diagonally.

After you feel the motor grab the filament,
continue to maintain pressure on the filament for
another five seconds.

--------------------------------------------------------------------------------

2. Object is stuck to
build plate

Wait for the object to cool down. Objects will
detach more easily after they have cooled.

If the object is still stuck, take a thin metal craft
spatula and carefully work the blade under the
edge of the object. When the blade is most of the
way under the object, twist the handle slightly. The
object should come free.

--------------------------------------------------------------------------------

3. Can't remove the
Filament from extruder

Run the filament load script in the onboard Utilities
menu and let the filament advance for about five
seconds. Then run the unload script again.

MAINTENANCE

-------------------------------------------------------------------------------------------------------------------------------------------

Lubricating the Threaded Rod and the X-Axis Idler Pulley

1. Find the tube of PTFE-based grease,
included with your wanhao 3d printer.

2. Grasp both sides of the build platform
and push it gently to the bottom of

duplicator 4/4X，Use a clean, lint-free rag

[or your finger],to spread the PTFE-based
grease onto the top section of the
threaded rod.Grasp both sides of the build
platform and move it to the top of the

duplicator 4/4X，Use a clean, lint-free rag

[or your finger] to spread the PTFE-based
grease onto the bottom section of the
threaded rod. Make sure you get the
grease inside of the threads themselves

3. Locate the X-axis idler pulley. If you are,facing the front of duplicator 4/4X, the
idler pulley is at the top left side. The idler pulley is one of the pulleys that allow
the rubber belt to move the extruder from left to right, or along the X-axis.The
pulley at the other side of the gantry is called the timing pulley and does not
require lubrication.

Cleaning the Drive Gear

-------------------------------------------------------------------------------------------------------------------------------------------

The drive gear is the part of the extruder that pushes filament through the
extruder. When you make things with your wanhao 3d printer , small pieces of
hardened PLA/ABS can stick to the drive gear. If you are having problems with
your extruder, cleaning the drive gear might help.

Unload the wanhao PLA/ABS Filament from the extruder. To start the script for

1.

unloading the wanhao PLA/ABS Filament, go to the LCD panel and select Utilities
> Filament Options > Unload.

Unscrew the two bolts at the lower corners of the fan guard using the 2.5 mm

2.

hex key included with your duplicator 4/4X .As one piece, remove the fan guard,
the fan, the heat sink, and spacers. Keep these pieces together and set them aside.

Unclip the motor wires.

3.

4. Pull the motor assembly out.

Find the drive gear on the motor shaft.Using a small instrument like a makeup

5.

brush, toothbrush or toothpick, remove all the pieces of filament stuck to the
drive gear.

Reseat the motor assembly.

6.

Plug in the motor wires

7.

Add the fan guard, the fan, the heat sink, and spacers to the front of the

8.

extruder and bolt them on.

Reload the wanhao PLA/ABS Filament. To do this, go to the LCD panel and
