About A10 3D Printer
Geeetech A10 3D printer is designed to be reliable, cost-effective and easy-to-assemble. Running
stably, it aims to provide users with quality printout and satisfactory printing experience. The modularized
design provides you with an easier assembly experience.
Keeping Prusa I3 3D printers’ gantry structure and with its build volume as 220*220*260mm³, A10
makes the best of the building platform and gives you a full view of the printing details. Its well-designed
extruder greatly reduces the risk of clogging or leaking. The V-shaped wheels and rails on each axis, made
from wear-resistant aluminum profile, could, in a large measure, reduce the printing noise and offer you a
quiet 3D printing environment.
Featuring printing accuracy of 0.1 mm, A10 delivers exquisite prints with delicate texture, sleek
contour and stable structure. A10 comes with OPEN SOURCE GT2560 control board, providing limitless
space for you to modify the firmware and tinker with your printer.

Preparation
Step1. Open the box, taking out the foam box containing your A10.
Step 2. Remove A10 3D printer from foam box and set it down on a stable surface.
Note:
You will see a printing residue on the printing platform, which indicates your A10 has already gone through
the 24 hours aging test, you can feel free to use.
Step 3. Checking accessories
Please check the accessories based on the items in the assembly paper.

1. Check Power Supply
The power supply unit and control board of A10 are installed in the bottom of the printer, saving space, as
well as lowering the gravity center of the printer to provide stable support for printing. The printer uses
DC24V, 15A power supply.
2. Software Resources
2.1 Repetier-Host
The Repetier-Host is a simple to use host software, which is be compatible with most firmware. You can add
and position your STL files on the simulated print bed and slice them all together. For slicing you can use
the built-in Slic3r slicer. Just call "Slice & Load" and the job gets delegated to the current slicer, showing its
output in the log window.
Download the Repetier host V 2.1.2 here.
For detailed information of Repetier Host please refer to our wiki.
For detailed using methods of the slicing software, slic3r, which comes with Repetier Host, please also refer
to our wiki.
2.2 Arduino IDE
The open-source Arduino Software (IDE) makes it easy to write code and upload it to the board. It runs on
Windows, Mac OS X, and Linux. The environment is written in Java and based on Processing and other
open-source software.
This software can be used with any Arduino board.
Download Arduino-1.0.1- here.
2.3 Firmware
A10 uses GT2560 RevB control board; you can download the corresponding firmware here.
To know how to upload the firmware, please refer to FAQ.

3. USB Driver Installation
3.1 USB Driver Installation for Win7 OS
Power the A10 up and connect it to computer with the USB cable, the driver will be installed
automatically. After installation, please enter Device manager and find the USB Serial Port which is the
communication port for the printer and computer.
If the driver can not be automatically installed, please download the USB driver here and manually install it.
3.2 USB Driver Installation for Mac OS
For installing the driver and uploading the firmware in Mac OS, please refer to FAQ.

4. Set up Repetier Host
The next step should be, to configure your printer so you can connect your computer with the host. Open
Repetier Host. Choose the language as English.
When you start Repetier Host for the first time, you need to set up parameters for A10. Click the Printer
Settings on the top right corner, you will be presented with the following window.

SHENZHEN GETECH TECHNOLOGY CO,.LTD

4.1 Create New Printer
Click “Printer Setting” and you see a drop down box, with the currently selected printer. At the start you
have only the default printer. To create a new printer you only need to change the printer name and press
“Apply”. The new printer will start with the same settings as the last selected printer.

There are six tags in Printer settings in total. Detailed configurations of the 4 relevant tags are as follow.
4.2 Connection
In this first tab, we will introduce how to connect your printer with the software.
Port： Get the printer connected to the port of computer, which is corresponding to the USB Serial Port in
the Device manager.
Baud Rate: Corresponding to the Baud Rate in firmware. Generally it is set as 256000.
For other parameters please leave them as default, and click Apply.

SHENZHEN GETECH TECHNOLOGY CO,.LTD
8
Note: If the operating system is Mac OS, please set the baud rate of the firmware and Repetier Host as
115200.
Open the firmware in Arduino, and modify the baud rate to 115200 in Configuration.h. Shown as
following picture.
After modification, re-upload the firmware:

SHENZHEN GETECH TECHNOLOGY CO,.LTD
9
After successfully modifying the baud rate in firmware, change the baud rate in Repetier-Host to 115200
as well.
About how to upload the firmware, please refer to FAQ.
Note: After re-uploading the firmware, you may need readjust the motor direction of the printer. For
detailed methods please refer to following motor testing part.
4.3 Printer
The second tab defines important behavior you want. The Travel feed rate and Z-axis feed rate are used,
when you move the extruder with the manual controls. The temperatures are set in the manual controls as
start values. You can change them there any time.

SHENZHEN GETECH TECHNOLOGY CO,.LTD
10
Set the parameters as shown in the picture
Travel Feed Rate: 3000 mm/min
Z-axis Feed Rate: 100mm/min
We suggest you to cancel the option of Go to Park Position after Job/Kill, or it may cause that the print
head impacts the printed model when it moves to starting position after finishing printing.
4.4 Extruder
In the “Extruder”tab you can define the numbers of extruder, the max temperatures, that are shown in the
manual control. The max volume per second defines the maximum amount of filament in mm³, the extruder
can melt per second.

SHENZHEN GETECH TECHNOLOGY CO,.LTD
11
Number of the extruder: 1
Diameter of the extruder: 0.4mm
4.5 Printer shape
The “Printer Shape”tab defines your printer shape, or to be more exact the shape of your build area. The
host will use this to limit your moves and to check, if your models fit onto the print bed. You can also define
the position of the x and y end stop.
Recommended settings:
Printer type: Classical printer
Home X：Max Home Y：Max Home Z：Min

SHENZHEN GETECH TECHNOLOGY CO,.LTD
12
X Min：0X Max: 220 Bed Left: 0
Y Min：0Y Max: 220 Bed Front: 0
Printing Area: 220 x 220 x 260 (length/width/height)
So far the setting of A10 is finished.

5. Function Testing
The firmware of A10 is already uploaded based on Windows 7 operating system, and we have done
debugging to make sure that every part of it can work normally. However, there may be unpredictable
factors during transportation . Please do the following simple test before using it.
5.1 Repetier-Host Test
5.1.1 Motor Test
Before the test, manually set the motors of X / Y / Z axis at the intermediate position of each axis to avoid
accidental collision occurring during the test. There is emergency stop button on the top right corner , or you
can cut off the power directly if anything went wrong. Be prepared for emergency stop.

SHENZHEN GETECH TECHNOLOGY CO,.LTD
15
Open Repetier host and connect the printer. Turn on the power supply. Connect the printer.
Click Home button , then the three axes will move towards the endstop in turn . After they touch
the endstop they will move back for a short distance and then stop the movement.

SHENZHEN GETECH TECHNOLOGY CO,.LTD
