-10\. Take the end of the wire from the X Carriage End Stop. Again you are going to skip a row from the previous plugged in end Stop and plug this End Stop into the 7th row. Use the picture as a reference. The red wire should be facing up, if plugged in backwards it will short the RAMPS causing permanent damage.
+10\. Take the end of the wire from the X Carriage End Stop. You are going to place it in a row right next to the previous plugged in end Stop and plug this End Stop into the 6th row. Use the picture as a reference (plug into 6th, not 7th as in the picture). The red wire should be facing up, if plugged in backwards it will short the RAMPS causing permanent damage. **IMPORTANT, SAVE THIS NOTE FOR CONFIGURATION STEP: when uploading the firmware, edit configuration.h and make sure X_HOME_DIR is set to 1, like so: #define X_HOME_DIR 1**.
