X-axis extruder Grinding Noise during calibration and MatterControl manually moving

Hey everyone, I've been using my R1 for about 2 months now and it's been working smoothly, until last week. I turned it on and went into MatterControl and heated up all the temperatures of the extruder. As I move the X axis of the extruder through the program it makes a grinding noise. The Z and Y axis are fine and then when the printer starts to calibrate the grinding noise happens again. How do I fix it? My prints are usually messing up now because of how much the extruder struggles to move on the z-axis. Any suggestions/comments/help are appreciated!

 

I was checking the wire bundle and I can't seem to figure out what is the culprit. Any more info as to what I am missing and how should I resolve this problem? Could you maybe include some pictures/info on the parts i should be checking?
