A RAMPS LCD control panel is a user interface for a RepRap Arduino Mega Pololu Shield (RAMPS) board, which is a type of electronics board used to control a 3D printer. The control panel typically consists of a 128x64 pixel monochrome LCD screen and a set of buttons for navigating menus and inputting commands.

To use a RAMPS LCD control panel, you will need to connect the control panel to the RAMPS board using a suitable connector or set of wires. The control panel will typically have a connector for the LCD screen and a set of pins or a connector for the buttons. You will also need to install a library or firmware that supports the control panel and provides functions for interacting with the LCD screen and buttons.

Once the control panel is connected to the RAMPS board and the appropriate software is installed, you can use the control panel to navigate menus, input commands, and monitor the status of the 3D printer. The control panel may also allow you to adjust settings, such as the temperature of the extruder or the speed of the motors, and to start and stop print jobs.

The intelligent controller includes an SD card reader, rotary encoders and a 20-character

× 4 line LCD display. You can easily connect it to your RAMPS 1.4 board using "smart

adapter" included.
 

This panel connect your RAMPS 1.4, you do not need your computer, your SD card

intelligent controller power supply. All further operations, such as calibration, the axis

movement can be done only with a rotary encoder intelligent controller. 3D design print

without a computer, just use the G code design stored on the SD card.
