The first thing that must be changed is to plug the X end stop into the Ramps board NEXT to the Y end stop plug and NOT skip a space. The pins to the right of the Y end stop pins is for XMAX. The one you show in your manual is for XMIN. That is at STEP 23, picture 10. “Again you are going to skip a row” is incorrect. It needs to go to the immediate right of the Y end stop plug.
Then in configuration.h in Arduino make sure that
#define INVERT_X_DIR true is CHANGED to #define INVERT_X_DIR false
AND
#define X_HOME_DIR -1 is CHANGED to #define X_HOME_DIR 1
Keep the plug for the X axis servo motor wires reversed as shown in the picture. Without an explanation, many people think that you made a mistake in the picture. Make note of the fact that the orientation of the colored wires is correct.
Finally, in Repetier, tell the user to go to printer settings/printer shape and change ‘home X’ from MIN to MAX.''
