FIRST USE OF YOUR WANHAO DUPLICATOR 6
D1. First time startup
This chapter guides you through the steps and the first run of the D6. After you switch on your Duplicator 6, the display will light up and guide you through.
Use of the display
You can navigate through the display by using the button. This button can be pushed and rotated. By rotating you can select or control an action. By pushing you can confirm an action. When pushing the button you hear a “beep” sound to confirm your chosen action. A blinking button means the D6 is waiting for user input.
Navigate to [MAINTENANCE], [ADVANCED] and confirm for a
[Factory reset] You can use this function for the first run wizard at any time
When you read this step confirm the [CONTINUE] to go the next step: Leveling the build plate
D2.Leveling the build plate
If the build plate is too far away from the nozzle your 3D-print might not stick to the build plate. Equally, if you adjust the build plate too close to the nozzle, the build plate can block the filament from extruding from the nozzle.
It can also scratch the build plate.
NOTE: After transportation you might want to level your build plate to ensure your 3D prints stick well to the build plate
How to level the build plate
When leveling the build plate you must follow the step 4/21 until 10/21 on the display where the first step 4/21 control the height by rotating this button.
In the step 5/21 you rotate this left build plate screw under the build plate to control the height between the nozzle and the build plate.
In 6/21 you adjust a similar build plate screw on the right hand side.
Rotating left means closer to the nozzle.
CAUTION: In these steps the print head will automatically move through the Duplicator 6. Also the Build plate will determine its destination by going up and down again.
Now, follow the display instruction 4/21 and, 5/21, [CONTINUE] when finished.
D2.Leveling the build plate (continued)
Follow the display instruction 6/21 and 7/21, [CONTINUE] when finish
We are going to do this again to fine tune the build plate. Please, make sure you have a piece of paper within reach and press [CONTINUE] to go to the next step. Make sure you turn the build plate screw to finetune this step if necessary.
8/21. Follow display instruction as demonstrated in the supporting image and press [CONTINUE] when finished.
9/21. Follow display instruction as demonstrated in the supporting image and press [CONTINUE] when finished.
10/21. Follow display instruction as demonstrated in the supporting image and press [CONTINUE] when finished.
NOTE: If you have problems, or if you need to level your build plate again, you can use the [BUILD PLATE] function under [MAINTENANCE] through the standard menu.
D3. Loading filament material
Now that we have completed the initial leveling tasks we [CONTINUE] and go to the step where we are going to insert filament material in the material feeder.
Please make sure you have a filament spool positioned over the spool holder, guided along the filament guide , with the filament in counter clockwise direction.
In this step, you need to wait a minute while the printhead heats up. Wait for the onscreen progress bar to reach 100%.
NOTE: The printhead will now move itself to the front automatically.
13/21. This step needs some extra focus. The wheel in the material feeder will start rotating slowly. Push the level and insert the filament into filament hole at top of extruder. There is one hole where it should go into right above the feeding gear. Follow the display instruction with the supporting images below but WAIT! Before pushing(CONTINUE) and check the next page for more instructions.
Push the level bar and insert the filament into the hole until very end of the extruder(roughly about 16cm filament length). You can see the filament pop out from the nozzle. This takes some force. Then release the level bar.
D3. Loading filament material (continued)
You can [CONTINUE] this step, 13/21, when the material is loaded until it reaches the Mk11 extruder nozzle.
The filament is being pulled through the MK11 extruder quickly. Once you see the filament getting out of nozzle, push the button to stop extruding.
Follow the instruction on the display. When the filament material exits from the nozzle, click the button to [CONTINUE].
WARNING: Do not touch the extruder while it is heating, it is heating up to 220° C
NOTE: Don’t be surprised if the material that initially comes out of the nozzle is not the color you expected. There’s probably some filament left inside the nozzle. This is caused by testing the UDuplicator 6 before packing. Wait until you see the color that you loaded comes out of the nozzle before you [CONTINUE]
Follow the display instruction 16/21 and 17/21. Make sure you choose the right material, this material type is usually indicated on the filament spool.
Press the [READY] to choose the material.
18/21. Confirm the selection by choosing [YES] or [NO]
D4. Make your first 3D print
It is important to tell your D6 which type of material it will be using. D6 will adjust its settings to match with specific materials.
[CONTINUE] to go to the next step
Now that the D6 has leveled its build plate and has material filament loaded, it can now begin to 3D print.
[ARE YOU READY] to go to the next step!
[LET’S PRINT] to start 3D printing! Your SD-card comes with the file
[wanhao Robot] click the button if you would like to print this file.
D5. 3D printing and print removal
After you have chosen your [wanhao Robot] to print your D6 will prepare itself and heat its print head nozzle and build plate. (This can take up to 5 minutes)
WARNING: Do not touch the extruder while it is heating and in use. Temperatures can vary between 220° C and 260° C
While printing, the LCD display will indicate the progress of your print and the remaining time to completion. There is also on screen, the options [TUNE] and [ABORT].
When your 3D print is finished, the display will indicate that the Duplicator 6 is cooling down.The progress bar indicates when it is safe to take out your print.
WARNING: Do not touch the print inside the D6 while it is still cooling down. Wait until the display tells you “Print Finished. You can remove the print”. Some parts are cooling down from a temperature of max. 260° C and might be still very hot.
Now your print and your D6 is at a safe temprature. You can remove the print.
Select the [BACK TO MENU] to start the next print. Also on this screen, you have the options to [CHANGE MATERIAL] and [MAINTENANCE].
Because you have completed the “First run wizard” this is now your home menu every time you start up your D6.

MAINTENANCE FOR YOUR WANHAO DUPLICATOR 6
F1. In General
To achieve the best possible results from your Duplicator 6, some basic annual maintenance is recommended. This chapter contains tips which helps you to keep the Duplicator 6 running at it’s best.
Before you make a print a quick check is advised. A visual check is recommended to see if there is not any:
- old prints/objects on the build plate.
- make sure no one can possibly walk over, damage or pull out the power supply cable.
Updating firmware with USB cable
Once a while Cura will give you a mention that new firmware available. New firmware means that we have optimize the control of the electronics which will gives
better print results and user experience. If you see this mention, connect the USB cable between your computer and your Duplicator 6 and follow the instructions in Cura.
F3. Change filament and material feeder
In the Duplicator 6 the filament material can be changed. As you have learned in previous steps there is no need to do this all by yourself because the Duplicator 6 helps you with that.
- Go to the [MATERIAL] tab on the main menu of the display. Press the button: next go to [CHANGE], this can be done by turning the wheel next to the screen. Press the button.
Note: firmware updates in the future may use a different terminology.
- Your Duplicator 6 will heat up so the material can be removed later. When the required temperature is met, the feeder will turn by itself and retract the filament.
- Rewind the filament on the filament spool and make sure it cannot uncoil at a later moment (secure with hole in spool, tape or anything that works).
- When you took the filament from the spool, you (can) replace it with a new spool, follow the instructions on the display.
- In the last step of the instructions we make sure that the printer knows what kind of material you have inserted in your machine. Select on the display the material that is identified on the spool
Clean material feeder
After a lot of printing, the wheel in the material feeder can accumulate small plastic particles.You can clean this by blowing air on the wheel or using a simple brush.
F4. Lubricating the axes
After approximately every half year the threaded rod on the z-stage has to be lubricated. A green grease (Magnalube-G) is included with the D6. This grease is the lubrication which has to be used on the threaded Z-stage rod.
Note: the green grease should be applied as is shown in the photograph.
Make sure you spread 10 drops of grease over the entire exposed threaded rod. With you next print on the Duplicator 6 the Thread will grease itself by moving up and down.
If you notice small wavers in the outside surfaces of your 3D printed objects.
It is recommended
to add a single drop of sewing machine oil onto the X and Y steel axes bars.
This will inprove the smooth movement of your Duplicator 6. This lubrication is not included in the Duplicator 6 package.
If you choose to lubricate the X- and Y-axis you
MUST use sewing machine oil . Apply a maximum of one droplet oil on the axis.
Remove any excess oil.
TROUBLEHOOTING AND SUPPORT FOR THE WANHAO DUPLICATOR 6
G1. Simple Troubleshooting tips
In case something goes wrong with your D6, the following chapter will help you. From diagnosing and fixing the problem yourself to contacting support.
Print detaches during printing or print does not stick at all.
Build plate is not properly leveled.
Follow the instructions under [MAINTENANCE] and then [BUILD-PLATE]
Use a spatula or another thin object such as a wedge between the glass and the object. Slowly push the wedge under the object from different directions. If the object will not release from the build plate try slightly tapping the wedge.
Material feeder ticks when loading new material Cause
Caution: be very careful when using a sharp tool to remove objects.
Material has reached the nozzle and is exiting the nozzle, the feeder cannot keep up with the flow.
While loading new material it is normal for the feeder to tick, the feeder is designed to tick backwards instead of grinding the material.
G1. Simple Troubleshooting tips (continued)
Not enough material is released from the nozzle.
Material feeder on the back of the Duplicator 6 is ticking while printing. Nozzle is blocked or partially blocked by dirt or burned material.
Increasing the print temperature to 260C while printing in an attempt to clear the blockage. If the blockage is removed keep printing at 260C for at least 10 minutes to clean out any residue.
Printing at 260C does not solve the blockage.
Something larger than 0.4mm could be blocking the nozzle. Cleaning the nozzle or replacing it is recommended. Contact support: firstname.lastname@example.org who will assist in fixing your Duplicator 6.
Material flow stops and material is ground down by the feeder.
Nozzle could be blocked or partially blocked.
See “Not enough material is released from the nozzle.” for causes and solutions.
Too much pressure is put on the material by the feeder.
Release the pressure on the feeder a bit by adjusting the build plate screw clockwise.
Too little pressure is put on the material by the feeder, causing the material to slip.
Put more pressure on the feeder a bit by adjusting the pressure screw counter clockwise.
Duplicator 6 display only shows “ERROR – STOPPED”, “Temp Sensor”
