Description
The 2004 LCD Smart Controller is the perfect upgrade for your RAMPS-based 3D printer, allowing you to operate your machine completely standalone. Featuring a high-contrast 2004 LCD display, a built-in SD card reader, and a responsive rotary encoder, this controller eliminates the need for a constant PC connection during your print jobs.
Whether you are performing manual axis movements, bed calibration, or starting complex prints directly from a G-code file on your SD card, this controller puts total control at your fingertips. It includes a “smart adapter” for simple, plug-and-play integration with your RAMPS board.
