12864 LCD Display Controller with SD Card and Encoder for RepRap RAMPS 1.4 3D Printer

12864 LCD Controller with SD Card Slot and Rotary Encoder Overview A compact controller panel that adds a large 12864 LCD screen, SD card printing, and rotary encoder adjustment to compatible 3D printer electronics. Designed for easy integration with RAMPSbased systems and for users who want standalone printing and ondevice parameter tuning. Key benefits Clear, easytoread 12864 LCD display for menus, status, and file selection. Print directly from SD card: copy Gcode files to an SD card, insert it into the rear slot, select the file on the LCD, and start printing without a connected PC. SD card not included. Builtin rotary encoder for smooth menu navigation and live parameter adjustment during setup and calibration. Designed to work with RAMPS setups with minimal wiring. Firmware must be updated to enable full support, allowing to match your printer configuration. Includes cables and connector for straightforward installation. Features and compatibility Display: 12864 LCD large screen for improved visibility and ondevice control. SD card base on the back for standalone file access and print initiation. Rotary encoder for parameter adjustment and intuitive file selection. Plug and play compatibility with RAMPS hardware; requires firmware modification to enable controller functions. Package contents: 1 x 12864 LCD controller (SD card not included), 2 x 30 cm cables, 1 x connector. Typical use scenarios Standalone printing: Transfer sliced Gcode to an SD card, insert into the LCD controller, choose the file on the screen, and start printing without a PC. Ideal for workshop setups or kioskstyle printing. Onthefly calibration: Use the rotary encoder to fine tune steps, speeds, and other parameters directly from the controller while monitoring changes on the large display. Hardware upgrade or replacement: Swap in this controller to add an SD card slot and improved user interface to a RAMPSbased printer. Installation and support Physical installation is straightforward with the included cables and connector. Firmware modification is required for full functionality; consult your firmware documentation for enabling external LCD and encoder support. Technical support is available for setup and troubleshooting if you encounter issues.
