Mount the PSU on the right side panel with 3 M3 x 10 screws.<br>
Then mount the AC socket with M3 x 20 screws.<br>
You have to take off one end of the connectors to get both the power button and the power socket into the hole.<br>

[[File:Prusal I3 manual pic82.jpg|400px]]

[[File:Power connect.jpg|400px]]

<font color="red">1. Mind the color of the wires. The wrong connection of the wire will cause serious damage to the PSU and even to the control board of the printer. </font><br>

[[File:Power1.jpg|500px]]

<font color="red">2. Pay attention to the switch on the right side of the PSU, there are two options of voltage: 110 V and 220V, choose according the standard in your country. As shown in the following picture.</font><br>

[[File:CHOOSE VOLTAGE.jpg]]

After connection, please close the protective cover  to avoid electronic shock.

=Mount the control board on the left side panel=

<font color="red">'''Example 1: Sanguinololu'''

Here we take the Sanguinololu as an example.<br>

Step1, plug the jumper caps on the following pins of the board. (In the yellow circle) <br>

<font color="red">* These caps are very tiny; do not throw them away inadvertently.<br>

The jumper caps are packaged along with the board, do not lost them.<br>

You need to plug 12 caps in all.<br>

[[File:Acrylic Prusa I3 (8mm)pic62.png|400px]]  [[File:Acrylic Prusa I3 (8mm)pic63.png|400px]]

Step2. Stack the 4 A4988 on Sanguinololu <br>
[[File:Acrylic Prusa I3 (8mm)pic64.jpg|500px]]

Step3. Stick the heat sink on the chip of the 4 A4988.<br>
[[File:Acrylic Prusa I3 (8mm)pic65.jpg|500px]]


Step4, connect all the wires to the interfaces of the board 

The referring wiring schematic diagram of Sanguinololu

<font color="red">* use the Dopont cable in the package to strech the wire of fan for extruder, you just need to connect the black and red one, leave the yellow one alone. 

[[File:Prusal I3 manual pic86.png|500px]]

also you can refer to the board cover.

For more information about Sanguinololu, please visit the [http://www.geeetech.com/wiki/index.php/Sanguinololu wiki page].

<font color="red">Note: when connect the other Y-motor, use the 4-pin M-F DuPont cable and pay attention to the directions of the wire. If you connect them reversely, the 2 Z motor will move in different directions.

Look at the colors of the wire.<br>

<font color="red">'''Example 2: Ramps 1.4'''

Step1.Plug the jumper caps on ramps 1.4. You need 15 jumper caps in total.
 
[[File:Jumper cap.jpg]]

[[File:Ramps1.4.png|500px|]]

Step2.Stack ramps 1.4 onto mega 2560.

[[File:IMG 5050.jpg|500px]]
 
Plug the 4 A4988 motor driver boards on ramps1.4; stick the heat sinks on the driver boards. 

(one for X, one for Y, one for extruder, two for Z) 

 
[[File:Ramps 1.4kit.jpg|500px|]]

Mind the directions of the driver boards. You can see the “GND” on the board.

'''Wiring'''

The referring wiring schematic diagram of Ramps 1.4 <br>
[[File:线路图.jpg|500px]]

1.Connect motors. X and Y motors are easier, here you need to notice the Z motor, you need two 4-pin DuPont cable to extend for 2 Z motors.

[[File:Motor connection.jpg|500px]]

[[File:Motor connection9.jpg|500px]]

[[File:Motor connection3.jpg|500px]]

2.Connect the fan; both the fan for extruder and the main board are connected like this. As to the fan for extruder, you need another 2-pin DuPont cable to extend.
Take off the adapters and plug the cable into the power port.

[[File:Fan6.jpg|500px]]  [[File:Fan3.jpg|500px]]

3.Connect the heatbed.

[[File:Connection hb.png|500px]]

4.Connect the extruder 

[[File:Connection extruder.jpg|500px]]

The 2-pin DuPont cable with adapter is for thermometry, the thicker one is for heating. 

5.Connect the end stops.
:Connect the wires to "S" and "-" pins.

[[File:QQ截图20150320153047.png|500px]] [[File:QQ截图20150320153032.png|500px]]

6.Connect the power supply.

First you should take off the white adapter.

[[File:Power cable.png]]

Then screw the cable into the power port. Notice the “+” and “-“
Red is “+”. Black is “-“.

[[File:Power connection.jpg|500px]]

Plug the other end into the PSU.

Note that, when mount the board, please put the power port towards the cooling fan, or there may be some damaged caused to the board. This is very important, especially for Rampms 1.4.

[[File:Acrylic Prusa I3 (8mm)pic69.jpg|500px]]

All the wires can be tied together under the printer, but you should make sure they don’t touch the belt.

'''Arrange the wires and tidy up them with the coil.'''<br>

'''The whole printer assembly work is already done.'''<br>
'''Hope you enjoy the whole process.'''
