Install the driver

The first thing you need to do is that install the driver.This is very important.Many customers give us feedback that their arduino software are always come out to “Error”.Most of all ,they have not installed the driver.This step is just for the starter.If you are a master of arduino ,just ignore this step.

If you have not use any arduino series board.You may not install the driver on your computer.Do not worry,here we go..

There are two ways to install a driver. It can be installed through setup or manually; the instruction below are for installing a driver manually:

The first way

when you plugged the usb cable in the computer and connect with you mega2560 board.The systems may prompt to install the hardware at your toolbar lower right corner of the windows.Then the systems will find the driver files automatically,then the driver will be auto installed.At this time ,please note that your systems cannot download the driver files from internet automatically,It is in high rate that it cannot find the driver files.We have provided you all of the arduino programmed files including the driver files.Now I decompress the .rar files on my” C :\ ”.And the arduino driver files path : C:\arduino-1.0.1\drivers

The second way

   Right click on “my computer”
   Choose “properties”
   Choose “device manager” (In Windows 2000, you have to choose  the “hardware” tab first and then “device manager”). This will display a list of the devices that are on your computer.
   Right click on the device and click  “properties”.
   Choose “driver” and click “update driver”
   You will be asked to browse for the new driver. the arduino driver files path : arduino-1.0.1\drivers

When the driver is installed successfully,It may reveal the icon below.I Know My computer language is in Chinese,but the icons of windows system is the same whether the system language is in English or Chinese.if you have not installed the driver successfully,then the rest of the steps are useless.You need not download the arduino software at the official website, because we have provided you the all arduino software files, When you downloaded and decompress the .rar files.The software might be install as well.


Note: If you have tried at list 3 computers and changed 3 USB cables,but you still find that there is nothing happened on the driver manger and no tip for installing the driver of megatronics at your toolbar lower right corner of the windows,then your main board may be broken.If so,you can contact us for solution.

Upload the programmed project in the mega board.

Do not be impatient to plug the ramps 1.4 board on the mega2560,it is unwise.When you upload the the project on the mega board,just Connect the Mega board on your computer


I did no open the arduino 1.0.1 software,Instead,I just find the marlin.ino file and dblclick. C:\arduino-1.0.1\examples\Marlin\marlin.ino


Note:The picture shows below may be unacceptable(Open the arduino first and drag the marlin.ino to the arduino software window.),But you can open the arduino 1.0.1 software and file–>open–>marlin.ino. Please do not change any programmed code we provide to you.


In the Arduino 1.0.1 software, I chose the Arduino Mega 2560 board and the good Serial Port COM15 (It just depends on you board.),Please do not change any programmed code we provide to you.just launched the upload.Please click the picture to browse the magnified picture



Components assemble.

Now,the project code have uploaded in the mega board successfully,you can disconnect the mega board with your computer and plug the ramps 1.4 in your mega2560 board.This step we want to light the LCD2004,so I just show you how to connect the LCD kit.The A4988 motor driver is just for the motor.It is useless for lighting the LCD2004,so I do not plug the A4988 drivers.


Note:Please do not mount the RAMPS 1.4 wiring cable at the opposite position.The following picture shows the right connection and the wrong connection.We have uploaded the project on the mega board,so we just need to assemble the kit correctly.Then give the kit 12V power supply.The LCD2004 will display normally.


The end of lighting the LCD2004.

Now for the Name 17 stepper motor

1,We have uploaded the programmed code to our mega board. It is time to assemble all the sets.It is so easy to assemble all the components together.At this step,we need to connect the motors with ramps 1.4 board.the following picture shows how to connect the cable correctly.


2,Please note that do not mount the A4988 motor driver on the opposite direction.Otherwise,not only your A4988 drivers will be burn up,but also your mega2560 board will be in ruins.


This time I just mount one A4988 driver,you can plug all of five A4988 dirvesr. Each A4988 driver just serves for one motor.



Note:Please double check that the kit. untight? No power? pin broken?Wrong mounting?When you give the kit 12V power supply,the motor will revolves around.


If you do think the Email cannot solve your problem.We also provide you chat online.My skype id “lenkernel”.Please feel free to contact me.I am is lance.

Best regard.

Thank you.
