Unfold and check the package

Unfold the package and take all the parts out to check the condition of the items. As you can see, all the parts are packed very carefully.

·All the acrylic plate has been etched with part ID and the plate is covered with a sheet of kraft paper, you need to tear them off. .

Tips:

Before assembly, you are advised to put all the parts, especially the screws and nuts in order, which will save you a lot of time looking for the required parts.
The part ID is corresponding to the number labeled on the bag of every part.

Assemble Y axis (the bottom part of the chassis)

Assemble the rods of a Y axis

Thread the nuts and washers into the two M10 threaded rods separately. The order should be:

1) Thread the acrylic fender (Y plate connecting plate) in the middle.

2) Thread the M10 washer > M8 spring washer >M10 nut > M10 nut > M10 washer on the left

3) Thread theM10 washer < M8 spring washer < M10 nut < M10 nut< M8 spring washer < M10 washer on the right

Step2. Assemble the 2 smooth rods

Required parts	Required number	Part ID

Then mount the AC socket with M3 x 20 screws.
You have to take off one end of the connectors to get both the power button and the power socket into the hole.

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.

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.

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

Mount the control board on the left side panel

Example 1: Sanguinololu

Here we take the Sanguinololu as an example.

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

* These caps are very tiny; do not throw them away inadvertently.

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

You need to plug 12 caps in all.

Step2. Stack the 4 A4988 on Sanguinololu

Step3. Stick the heat sink on the chip of the 4 A4988.

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

The referring wiring schematic diagram of Sanguinololu

* 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.

also you can refer to the board cover.

For more information about Sanguinololu, please visit the wiki page.

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.

Example 2: Ramps 1.4

Step1.Plug the jumper caps on ramps 1.4. You need 15 jumper caps in total.

Step2.Stack ramps 1.4 onto mega 2560.

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)

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

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.

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.

3.Connect the heatbed.

4.Connect the extruder

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.

6.Connect the power supply.

First you should take off the white adapter.

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

Plug the other end into the PSU.

For more information about ramps 1.4, please visit the ramps 1.4 wiki.

Step5. Mount the board on the left side panel of the printer. And cover the board with the acrylic plate.

Required parts	Required number	Part ID
M3 x20 screw	4	NO.27
M3 x40 screw	2	NO.30
M3 nut	4	NO.11
spacer	4	NO.48

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.

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.

The whole printer assembly work is already done.
Hope you enjoy the whole process.
