SETUP
Warning! Take care not to remove or damage the yellow tape on the build platform. This
tape is essential to ensure the 3D model properly adheres to the build platform during
printing. If this tape becomes damaged or wears out, replace it with painter's tape,
Kapton® tape, or ordinary masking tape.
Perform the following steps to prepare the printer for use.
1. Remove the printer from its packaging and place it on
a flat, stable surface with plenty of ventilation and a
nearby AC power outlet.
2. Open the Accessories box and remove the Filament
Rack. Slide the tab at the flat end into the slot on the
left side of the printer frame.
3. Ensure that the power switch on the rear panel is in the OFF position (Oside
depressed). Plug the C13 end of the included AC Power Cable into the C14 panel
connector on the AC Power Adapter, then plug the other end into a nearby AC
power outlet. Depress the Iside of the power switch to power the printer ON.
4. Rotate the control wheel clockwise to move
the highlight to the Move entry, then press the
center of the control wheel to open the Move
menu.
5. Rotate the control wheel clockwise to move
the highlight to the Home Axis entry, then
press the center of the control wheel to activate the Home Axis function. The
printer will move the extruder head to the "home" position.
6. Turn the printer off by depressing the Oside of the power switch.
7. Slide a sheet of A4 paper between the build platform and the extruder nozzle. The
extruder height above the build platform should be 0.05mm, which is the thickness
of a sheet of A4 paper. The extruder is at the correct height when the sheet of

8
paper can be slid between the nozzle and the
platform without binding. When the extruder
head is moved or when the paper is moved
under it, there should be a slight amount of
resistance, but the paper should not be
dragged with the extruder when it is moved.
If the height is incorrect, use the included hex
wrench to make slight adjustments to the
platform height by turning the screws at each
corner of the platform. Turn the screws
clockwise to lower the platform and
counterclockwise to raise the platform. Turn
the wrench no more than 1/4 turn each time,
then recheck the height. Continue checking
and adjusting until the height is correct at all
points on the platform.
8. Insert the included microSD™card into the slot
on the right side of the printer.
9. Turn the printer on by depressing the Iside of
the power switch on the rear panel.
10. Rotate the control wheel clockwise to
highlight the Temperature entry, then press
the control wheel to open the Temperature
menu.
11. Use the control wheel to highlight the Extruder
entry, then press the control wheel to edit the
value. Rotate the control wheel to set the
temperature to the target temperature for the
type of filament you plan on using.
12. Using the same procedure, set the Platform temperature to the target temperature
for your filament type.

9
13. If the button under the Extruder and Platform reads Start Preheat, use the control
wheel to highlight the Start Preheat entry, then press it to start preheating the
extruder and build platform. The button will change to read Stop Preheat and the
Extruder and Platform buttons will read the actual temperatures.
14. While the printer is heating, open your filament. Using a pair of scissors or side
cutters, diagonally snip the end of the filament to make a point, as shown in the
images below.
15. Using the control wheel, navigate to the Move menu, then select the Z Axis option
and press the wheel. Turn the control wheel counterclockwise to raise the extruder
off the build platform.
16. Place the filament reel on the filament rack on
the left side of the printer.
17. While squeezing the lever on the Feed
Mechanism, insert the filament and push it into
opening. Keep pushing until you feel resistance
as it hits the extruder. Release the lever on the
Feed Mechanism.
18. Using the control wheel, highlight the Extruder
entry on the Move menu. Press the control
wheel, then turn it counterclockwise to feed
filament into the extruder. Continue until
filament starts to extrude out of the nozzle.
Wait until filament is no longer coming out of
the nozzle.

10
19. Using the included plastic scraper, clean the extruded filament from the nozzle and
build platform.
20. Using the control wheel, select the Print option
from the main menu. The printer will read the
contents of the microSD™card and display
them on screen. Highlight the cat.gcode file,
then press the control wheel to start printing
the model.
21. After the first layer has been laid down, use
the control wheel to Pause or Cancel the
printing operation. Examine the layer and
compare the printed material with the images
in the table below. If the result is wrong, turn
off the printer and re-adjust the platform
height as indicated. Clean off the printed material using the included plastic scraper,
then print the model print again. Keep repeating this process until the result is
correct.
Wrong
The nozzle is too far from the
platform. This can result in the
extruded material not sticking to the
build platform.
Correct
The nozzle is at the correct height
above the platform.

11
Wrong
The nozzle is too close to the
platform. This can result in damage to
the nozzle and build platform.
Congratulations, your 3D printer is setup and ready for use!
WI-FI SETUP
You can connect the printer wirelessly to a 2.4Ghz Wi-Fi® network to print models from
your Android™ or iOS® phone or tablet. Perform the following steps to setup the Wi-Fi
connection for your device.
1. Download the free MP 3D Printer WiFi Connect app from the Google Play Store or
from iTunes, depending on which type of mobile device you have.
2. Disconnect the USB cable from the printer. You cannot use USB and Wi-Fi
connections at the same time.
3. Power on the printer.
4. Start the MP 3D Printer WiFi Connect app.
5. The SSID of your Wi-Fi network should be displayed on screen. If a different SSID is
displayed, open your device's Wi-Fi settings and select the appropriate Wi-Fi
network.
6. Enter your wireless password.
7. Use the printer's buttons to navigate to the Move menu.

Note that you may have difficulty connecting to the Wi-Fi network if you have a 2.4GHz
and 5GHz network with the same SSID. Try changing the SSID of the 5GHz network if this
occurs. For best results, move the printer to a location closer to the Wi-Fi router or access
point.
SOFTWARE INSTALLATION AND SETUP
As you've seen, you can print a model directly from a gcode file on a microSD™card and
this is the preferred method, as it does not require a continuous connection to your
computer. You can download gcode files to the microSD card and print them without
having to build any model files.
However, you can create your own gcode files using an open source program, such as Cura
or Repetier-Host, which are pre-installed on the microSD card that comes with the printer.
These programs use M200 models (typically .STL or .OBJ files) and, using machine specific
information, generate a gcode file with detailed instructions for the printer to create the
selected model. We recommend you start with Cura, since it includes a Slicing Engine.
Installing Cura for Windows
1. Use a card reader to read the contents on the
included microSD™card. Locate and double-
click the Cura_15.04.2.exe file to start the setup
program.
2. You may choose a new location for the
program files or accept the default
(recommended). Click Next to continue.

13
3. Ensure that all boxes are checked, then click Install to continue.
4. Once the files have been extracted and the Cura installation is complete, the driver
installation wizard will launch. Click Next to continue.
5. Click Finish to complete the driver installation.

14
6. Click Next to continue.
7. Ensure that the box next to the Start Cura 15.04.2 option is checked, then click Finish
to complete the installation and launch the program.
8. Wait for Cura to finish launching. If this is the first time you have run Cura on this
machine, Cura will automatically launch the First time run wizard. Otherwise, you
will need to select Machine > Add new machine.

15
9. Click the button next to the Other option, then click the Next button to continue.
10. Select the Custom... option, then click Next to continue.

16
11. Click the button to the left of the Other entry, then click Next to continue.
12. Change the settings to match those shown in the images below, then click Finish to
continue.
13. The program will finish launching and leave you on the main screen. Select the Basic
tab, then change the settings to match those in the accompanying image for PLA
filament.

17
Note that the Fill density, Support type, and
Platform adhesion type options should be set
according to the needs of the model you are
printing.
The Fill density will determine the overall
strength of the finished object. If printing a
decorative object, a low fill density is
appropriate. However, if printing an object that
will be used as a tool or part (e.g., a gear), a
high fill density will impart maximum structural
strength to the finished object.
If printing something with no overhang, such
as a cube, you can set the Support type to
None. If the model has areas that overhang the
build plate, but which are not overhanging a lower section, you can use the
Touching buildplate option. The Everywhere option is usually only necessary for
very complex models with parts that overhang other parts.
In most cases, the Brim option for the Platform
adhesion type is sufficient and is easier to
remove and clean up. The Raft option builds a
flat layer on which the model is then built and
will need to be removed once the print is
complete.
Feel free to experiment with these options to
achieve the best possible print.
14. Click the Advanced tab, then change the
settings to match those in the accompanying
image. Note that if you have a very high fill
density (from the previous step), you will want
to increase the Cool down time (Minimal layer
time) to 10 seconds.

18
15. Finally, using the included Micro USB cable, plug one end into the USB port on the
printer, then plug the other end into an available USB port on your computer.
Watch the right hand corner of the screen. A bubble will appear in the lower right
corner of your desktop, which is telling you that Windows is installing the necessary
printer drivers. Click the bubble and verify that the drivers have been properly
installed.
Congratulations, you have installed Cura and connected your PC to your new 3D printer.
Refer to Cura's documentation for operating details and information on the various
options.
Repetier-Host
You can also install Repetier-Host from the file on the included microSD™card or from a
download from the internet. The screenshots below show the proper settings to use for
