Setting up your Firmware on the Acrylic i3 or the 2020 i3
The firmware can be found on the google drive link along with the build guide.
You will need to install the Arduino IDE which can be downloaded for free from http://arduino.cc If your kit uses the RAMPS 1.4 controller, you will have a 'Mega 2560' board.
By default the code has been setup to run the 2004 LCD, but you do not need the LCD to run the code.
No firmware changes are needed on the i3 kits.
