How do I load the firmware to the controllers? I finished building the Prusa i3 Acrylic Pro http://www.geeetech.com/wiki/index.php/ ... ction(8mm) and when I power it on a green light on the controller board blinks twice and the LCD panel lights up, but there is nothing on the LCD screen (it is blank) and nothing happens at all. Do I need to load the firmware?
