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.
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
Step1. Assemble the 2 threaded rods.
Required parts | Required number | Part ID |
---|---|---|
Thread the nuts and washers into the two M10 threaded rods separately. The order should be:
- M10 washer > M8 spring washer >M10 screw > M10 screw > M10 washer > acrylic fender > M10 washer > M8 spring washer > M10 screw > M10 screw > M8 spring washer > M10 washer
Step2. Assemble the 2 smooth rods
Required parts | Required number | Part ID |
---|---|---|
- Slide 2 bearings on each smooth rod. Before you slide the bearings please make sure they are clean.
Attach the front and rear Acrylic support plates of the rods
Required parts | Required number | Part ID |
---|---|---|
Slide the rods into the acrylic plate, Adjust the length so that the smooth rods fit snugly between the front and back piece.
Each corner gets a washer and a nut. Adjust the inner and outer nuts so that the end of the rod is flush with the outside M10 nut.
Do the same on all four corners.
Tips: the Y-axis must be a rectangle, that is the rods on both side should be parallel, so is the front and back plate. Otherwise it will cause obstruction for the belt later.
Assemble the Y idler

Step1. Thread the M3 x 20 screw through the Y idler piece.
Put the M4 x25 screw through the holes with the 624ZZ bearings in between. Lock the other end with a M3 nut.
Step2. Mount the assembled idler onto the front support plates. And screw it with a wing nut.
*Please leave enough room for the belt between the ball bearing and the screw.
Mount the Y motor
Required parts | Required number | Part ID |
---|---|---|
Step1. Mount the pulley on the motor shaft, one of the screws should be screwed on the cross section of the shaft. Do not screw too tight to turn smoothly.
Insert the motor block into the slot; you may need to use a little strength to do this. But be careful in case the Acrylic broke down. Then screw the motor on the block plate with M3 x 12 screws.

Mount the PSU
Required parts | Required number | Part ID |
---|---|---|
Mount the PSU on the right side panel with 3 M3 x 10 screws.
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.
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.

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.
