RAMPS 1.4 Smart LCD Controller w/ SD Reader from MakerGeeks.com

(info from RepRap.org Wiki) This Smart Controller contains a SD-Card reader, an rotary encoder and a 20 Character x 4 Line LCD display. You can easy connect it to your Ramps board using the "smart adapter" included.

After connecting this panel to your Ramps you don't need your pc any more, the Smart Controller supplies power for your SD card. Further more all actions like calibration, axes movements can be done by just using the rotary encoder on the Smart Controller. Print your 3D designs without PC, just with a g-code design stored on the SD card.

Each MakerGeeks.com RAMPS 1.4 Smart LCD Controller w/ SD Reader Includes:

• 1 Smart Adapter so you can plug right into your RAMPS 1.4 board
  
• 1 Smart Controller with built in SD Card slot
  
• 1 set of Ribbon Cables to connect your Smart Controller to your RAMPS board
  

Here is what you'll need to change in your config files to get your RAMPS 1.4 / Arduino to read from the MakerGeeks.com Smart Controller:

Marlin V1 (new)

In "Configuration.h"
Change line 46 to —#define MOTHERBOARD 33"
Change line 306 to —#define REPRAP_DISCOUNT_SMART_CONTROLLER" (just remove the // at the beginning)
Change line 326 to —#define NEWPANEL //enable this if you have a click-encoder panel" (just remove the // at the beginning)
Switch over to "Pins.h" and change line 318 to —#define RAMPS_V_1_3" (just remove the // at the beginning)

Upload the firmware, power off the Arduino, connect the panel, reapply power, and everything should work.

Marlin V1 RC2 (old)

Settings for RAMPS1.4 in "Configuration.h" search for "ULTIPANEL" and activate the define (remove the leading "//")
define ULTIPANEL
and
define NEWPANEL //enable this if you have a click-encoder panel
Also change the value on "define MOTHERBOARD" to 33
in "pins.h" go to section for RAMPS configuration (search for "MOTHERBOARD == 33")
