3018 CNC X axis Noise Reduction, Reduce Vibration Fix Endmill Chatter Solid Coupler upgrade

I was kind of surprises when I saw these spring couplers on the more expensive 3018 CNC. Normally on the cheaper 3018 I see the solid couplers. one of my locking bearing blocks has a lot of play from the factory. I decided to upgrade to Solid couplers and be done with it.
