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.

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.
8. Press and hold the center button for 3 seconds. Release the button when Smart
config started is displayed on screen.
9. Press the Connect to WiFi button on your mobile device. The connection will be
completed within 10 ~ 60 seconds and the message MP Mini Delta is now

be displayed at the top of the printer's LCD screen.

10
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.

11
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.

12
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.

13
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.

14
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.

15
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.

16
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 Z0.4 ;auto-levels the build plate with a vertical offset of 0.4mm
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 0.4 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.

17
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.
