RAMPS 1.4 3D LCD Controller With SD Card Slot

The RAMPS 1.4 2004 LCD Controller is a practical upgrade for compatible RepRap-based 3D printers. Its 20-character × 4-line LCD displays printer menus and status information, while the rotary encoder lets users navigate options and select commands.

The integrated SD card slot allows users to load compatible G-code files and start prints directly from the controller, reducing the need to keep a computer connected during printing. When correctly connected to a compatible RAMPS board and supported by the installed firmware, the controller can also provide access to functions such as axis movement, calibration, and other printer settings. reprap.org
