Assemble Manual of Geeetech Acrylic Prusa I3 (5mm)
Prologue Note: This manual only applies to the 5-mm acrylic Prusa I3. We have another one that is 8-mm.
As picture is much more helpful than words in assembly manual, so I use plenty of pictures and less word.
Unfold the package and take all the parts out to check the condition of the items.

Assemble Y axis (the bottom part of the chassis)
1.1Assemble the rods of a Y axis
Required parts | Part ID |

Step1. Assemble the threaded rod
- Thread the nuts and washers on the two M10 threaded rods separately. The order should be:
- M10 washer > M8 spring washer M10 screw > M10 screw > M10 washer > >A 12> M10 washer > M8 spring washer > M10 screw > M10 screw > M8 spring washer > M10 washer
Step2. Assemble the Y axis smooth rod
- Slide 2 bearings on each smooth rod. Before you slide the bearings please make sure they are clean. (Ignore the black one in between)

Step2. Mount the idler into the following part
Step3. Assemble the 2 smooth rods.(380 mm)
- Slide 2 bearings on the each rod as shown in the picture.
Slide the X-axis motor-end and the idler-end onto both ends of the smooth rods. The X-axis motor-end is on the left and the idler-end on the right. This is going to take some force, or you can use file to make the holes lager.
Mount the brass nut on the following part.
Insert the rest bearings into the bracket of both end of the smooth rod.
Thread the threaded rod through the following part. It would be easier to do it now.
Mount the aluminum plate under the extruder.
Fix the two pulleys on both if the threaded rod. And plug it on the motor shaft.
Assemble the X-Z axis.

Step1. thread the X-axis through the Z axis.
Step2 assemble the top mount of the Z-axis.
Mount the extruder on the X axis
step1. Thread the zip-tie through the extruder bracket.
Step2. Mount the extruder bracket on the smooth rod and insert the two bearings into the bracket. Tie up the Y belt then.
Step3. Amount the extruder support.
Step4. Mount the extruder
This is the fully assembled MK8 extruder.
Take the nozzle part and the bolt out.

Mount the LCD panel frame
Mount the filament spool
So far, the framework of the 3D printer is almost finished.
mount the control board on the left side panel
Ramps 1.4 + Mega 2560 + A4988
Stack the Ramps 1.4on the Mega 2560 and plug the 5 A4988 on the Ramps 1.4.
Sanguinololu
Plug the 5 A4988 on Sanguinololu
Mount the PSU on the right side panel
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.
Wiring
PSU wiring
Do make sure you connect the wires correctly, otherwise it may lead to damage to the control board and the PSU.

2) The referring wiring schematic diagram of Sanguinololu
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.
All the wires can be tied together under the printer, but you should make sure they don’t touch the belt.
The whole printer assembly work is already done.
Next is the testing and debugging.
