PRINTER SETUP
Warning! Take care not to remove or damage the black PEI build mat on the build platform.
This mat is essential to ensure the 3D model properly adheres to the build platform during
printing. If this mat 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.

3. Continue pushing until the print begins to lift off the bed, try to push the scraper
further under the print.
4. If you encounter difficulty pushing the scraper under the print, try approaching it
from another side or try working the scraper around the perimeter of the print.
Continue pushing until you can slide the scraper all the way under the print, then lift
the printed model off the bed surface.
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 and install 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

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.

12
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.
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.

13
5. Click Finish to complete the driver installation.
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.

14
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.
9. Click the button next to the Other option, then click the Next button to continue.

15
10. Select the Custom... option, then click Next to continue.
11. Click the button to the left of the Other entry, then click Next to continue.

16
12. Change the settings to match those shown in the images below, then click Finish to
continue.

17
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.
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

18
previous step), you will want to increase the Cool down time (Minimal layer time) to
10 seconds.
15. Click the Start/End-GCode tab.
16. Add the following line to the start.gcode code,
after the 2nd G28 line (the new line is
highlighted in the image below):
G29 C-0.8 Z0.3 auto-levels the build
plate with a vertical offset of 0.3mm
and a center offset of -0.8mm
The models on the included microSD™ card
have this line already inserted, but if you will
be making your own model files, you will need
this line to instruct the printer to activate the
auto-leveling feature. The 0.3 value represents
the amount of vertical offset intended to
compensate for the thickness of the build
plate mat. If the first layer is too tight, you can
increase this value, while if the first layer is too loose, you can decrease it. This value
has a 0.1mm tolerance.

19
17. 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
this printer in Repetier-Host.
