Rear z-axis motor not running smoothly

So I finally got round to building my v-core 3 500, got the bltouch setup and ran my first home which worked. I then ran z-tilt and the rear didn't rise up far enough. I looked closer and saw that it wasn't running smoothly, it stopped and then started again. I checked the electrical connections and it looks good. Any ideas?

[solved] lead screw coupler wasn't quite tight enough. After tightening coupler to NEMA17 motor, it works.
