Ну вообще-то "It works on Gen6, Ultimaker, RAMPS and Sanguinololu"
А так курите мануал, там есть ссылка в разделе Electrical testing

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.
