Interfacing 3D Printer Ramps 20X04 LCD Smart Controller with Arduino
Using this display, you don’t need a computer to control your 3D printer anymore. In this shield, an SD card is used to transfer the 3D designs to the 3D printer and store the G-Codes. This shield consist of a 20x04 Character Line LCD.
Using the rotary encoder on the board, you can move in the device menu and access data. This display is compatible with ramps 1.4 controllers and can be run with marlin and repiter firmwares.
