== Install Driver Software and Development Environment Software IDE ==
<br>
=== (1) Install Diver Software ===
For different operating system, there may be slight difference in installation method. Below is an example in WIN 7. <br>
'''a.''' When you connect Keyestudio CNC GRBL V0.9 to your computer the first time, right click “Computer” —>“Properties”—> “Device manager”, you can see “USB2.0-Serial”. 
<br>[[File:图片1.png|500px|frameless|thumb]]<br>

'''b.''' Click “USB2.0-Serial”, select “Update Driver software”.
<br>[[File:Ks0311-b.png|500px|frameless|thumb]]<br>

'''c.''' In this page, click “Browse my computer for driver software”.
<br>[[File:Ks0311-c.png|500px|frameless|thumb]]<br>

'''d.''' Find the “usb_ch341_3.1.2009.06” file. 
<br>[[File:图片4.png|500px|frameless|thumb]]<br>

'''e.''' Click “Next”, Installation completed; Then，click “Close”. 
<br>[[File:Ks0311-e.png|500px|frameless|thumb]]<br>

'''f.''' After driver is installed, go to “Device manager” again. right click “Computer” —>  “Properties”—> “Device manager”, 
you can see device as below figure shown, also the correct Com port.  
<br>[[File:311图片1.png|500px|frameless|thumb]]<br>

<br>

=== (2) Install Development Environment Software IDE ===
'''a.''' Double click arduino-1.5.6-r2-windows to start. Select “I Agree”to accept license agreement.
<br>[[File:Ks0311-(a).png|800px|frameless|thumb]]<br>

'''b.''' Select components to install and click “Next”.
<br>[[File:Ks0311-(b).png|800px|frameless|thumb]]<br>

'''c.''' Click “Browse” and select another folder. Click “Install” to start the installation.
<br>[[File:Ks0311-(b-).png|500px|frameless|thumb]]<br>

'''d.''' Finally, wait for a few minutes to finish.

At last, click ”Finish” to finish the installation.

<br>
<big>'''c. Test G-Code on Grbl Controller'''</big><br>
Power the main board using a USB cable and connect correctly all your external devices, then run Grbl Controller.<br>
Choose Port name the same as IDE COM port and click “Open” to open the series port, connecting CNC Machines with computer.<br>
<br>[[File:94 4-10.png|500px|frameless|thumb]]<br>

After opening the series port, the “Open” button change into “Close/Reset” and get red! <br>
At this time you can click the X axis、Y axis、Z axis as shown in below diagram to adjust the motion direction of motors.<br> 
<br>[[File:94 4-11.png|500px|frameless|thumb]]<br>

<span style=color:red> '''Note:''' after adjusting the axies, before beginning G-Code file, you must close and open again.</span><br>
Now, it is time to have a try! Click ”Choose file” to choose one G-Code file named '''cn.''' to test in the data packet for a beginner, and the interface will come out: <br>
'''GrblController'''
