SETUP
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 AC
Power Adapter into the power input jack on the printer. Next, plug C7 end of the
included AC Power Cable into the C8 panel connector on the AC power adapter,
then plug the other end into a nearby AC power outlet.
4. Insert the included microSD™card into the slot on the right side of the printer.
5. Turn the printer on by depressing the Iside of the power switch on the rear panel.
6. Once the printer has initialized and the home
page is displayed, touch the Preheat button to
enter the Preheat Menu.
7. Touch the Nozzle button, then set the
temperature of the nozzle to the value
appropriate for the type of filament being
printed.
8. Touch the Bed button, then set the
temperature of the build plate to the value
appropriate for the type of filament being
printed.
9. Touch the Start Preheat button to start preheating the nozzle and build plate. Once
the target temperatures are reached, the button will change to Stop Preheat and
the displayed nozzle and bed temperatures should be at or near your target values.

8
10. 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.
11. Touch the Back button on the Preheat Menu to return to the Main Menu, then
touch the Move button on the Main Menu to enter the Move Menu. Touch the
button to raise the extruder above the build platform.
12. Place the filament reel on the filament rack on the
left side of the printer.
13. While squeezing the lever on the feed mechanism,
insert the filament and push it into the opening.
Keep pushing until you feel resistance as it hits the
extruder, then release the lever.

9
14. If the Main Menu is displayed, touch the Move button to enter the Move Menu. If
already on the Move Menu, touch the button (enclosed in red in the image
below) to start feeding filament into the extruder. Continue touching the button
until several centimeters of filament have been extruded.
15. Using the included plastic scraper, clean the extruded filament from the nozzle and
build platform.
16. Touch the button to return to the Main Menu, then touch the Print button to
display the contents of the microSD™ card. Touch the cat.gcode entry to begin
printing the model.
17. After the first layer has been printed, touch the Pause or Cancel button to stop the
print process.

10
18. Compare the first layer with the images in the table below to determine whether
the build platform needs to be leveled or not. If it does need adjustment, touch the
Cancel button, then perform the steps in the AUTO LEVELING section.
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.
Wrong
The nozzle is too close to the
platform. This can result in damage to
the nozzle and build platform.

11
AUTO LEVELING
If the gap between the nozzle and the build platform is not correct, use the Auto Level
function to adjust the gap. You will want to perform Auto Leveling after you unbox the
printer or move it.
1. With the printer powered on and the Main Menu displayed, touch the Move button
on the Main Menu, then touch the button to enter the Bed Level Correction
Menu.
2. Touch the Auto leveling button. The printer will measure the distance between the
build platform and the nozzle and will automatically set the gap to the proper value.
3. If you have added something to the build surface (e.g., glass sheet, steel sheet, etc.),
you will need to account for the thickness of the surface to prevent the extruder
from driving into it. With the ability to
adjust the offset locally in the menu
system, swapping surfaces is much
easier than managing the process
through software and sliced with the
model. If you wish to adjust the gap,
touch the +or -buttons. Note that the
offset must be less than zero.
4. Once the gap is where you want it, touch the button to save the data and exit
the menu.

12
LIVE LEVELING
While printing the model, you can use this function to fine tune the gap between the
nozzle and the bed. Touch the Tune button to enter the Bed Level Correction menu, then
touch the FAR button to increase the gap between the nozzle and the bed or the CLOSE
button to decrease the gap. Note that the Bed Level Correction value must be less than
zero.
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. Press and hold the Move button on the Main Menu for 3 seconds. Release the
button when Smart config started is displayed on screen.

13
8. Press the Connect to WiFi button on your mobile device. The connection will be
completed within 10 ~ 60 seconds, the message MP Select Mini Pro is now
connected to Wi-Fi will be displayed on your device's screen, and the IP address will
be displayed at the top of the printer's LCD screen.
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 MP Select Mini V2 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
1. Use a card reader to read the contents on the included microSD™card. Locate and
double-click the Cura_3.3.1.exe file to start the setup program.

14
2. Click the Next button on the Welcome screen, then click the I Agree button on the
License Agreement screen.
3. Use the file browser to select an install directory or accept the default directory
(recommended). Click the Next button to continue.

15
4. Ensure that all boxes are checked, then click Install to continue.
5. Click Finish to complete the installation and launch the Cura program.
6. Click Printer > Printer > Add Printer...
7. Click the Other option, then choose the Monoprice Select Mini V2 (E3D) entry. Click
the Add Printer button to continue.

16
8. The Machine Settings screen will display. Click the Finish button to continue. You
can now use Cura to print models and create gcode files for your printer.
Congratulations, you have installed Cura and connected to your PC to your new 3D printer.
Refer to Cura's documentation for operating instructions.

17
Repetier-Host
You can also install Repetier-Host from the file on the included microSD™ card. The
screenshots below show the proper Repetier-Host settings to use for this printer.
