Revision as of 03:22, 7 April 2015

Notice:

1. This kit contains tiny parts; please keep them away from kids under 3.

2. This building instruction applies to Geeetech Acrylic Prusa I3 pro C.

3. Some pictures of the printed part may be a bit different from those in your package, no worries, they work the same, and the way to assemble is similar.

4. Building and operating 3D printer involves electricity, so all necessary precautions should be taken and adhered to.

5. Building a 3d printer requires a certain amount of handling ability and basic knowledge of working principle of 3D printer.

6. Be patient, please. If you have any problems assembling, please contact us, we will try our best to help you.

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:

1. 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.
2. 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.

Y plate connecting plate	2	NO.A14
M8 spring washer	6	NO.18
M10 washer	8	NO.9
M10 nut	8	NO.12

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

Step1. Slide the rods into the acrylic plate; adjust the length so that the smooth rods fit snugly between the front and rear piece.

Step2. Screw up the rods and plate with M10 nut and M10 washer.

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. You can use a Digital Caliper to measure. .

First you have to take off one end of the connectors to get both the power button and the power socket into the hole.

*(The connection of wire in this picture is very important; you should pay close attention in case the PSU suffer a shortcut)

Step3. Connect the power cable to PSU.

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.You can use some hard sticks to reach the switch.

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

Mount the control board on the left side panel

Before you start wiring, please take a look at the wiring schematics.

There is one thing you need to note that the extruder number in this picture is 1 and 2, but in the following steps, I referred them as 0 and 1 correspondingly.

Step1

The subdivision of stepper motor can be setup by dial switch, turn on all the dial switches.

Step2

Plug the 5 A4988 into the stepper motor driver slot. Mind the directions of A4988.

Step3

Connect wires for motors.

1) Connect wires for X-axis motor.

2) Connect wires for Y-axis motor.

3) Connect wires for Z-axis motor.

Here you need to use the DuPont wire (NO.64).

Plug the end with one terminal into the Z motor slot. And connect the two wires of Z motor to the two DuPont wires separately.

Note the color of the connection as below:

DuPont wires	Motor wire!
Red	Blue
Black	Red
Blue	Green
Purple	Black
