Ringing/X-Axis Layer Shift at same place on all prints
I build my MK2 back in January and have been printing fine since. However, I recently moved my printer from my floor to a table and have been having a very serious issue. As shown here: 
All of my prints have this "micro-shifting" in the exact same spots, only on the X-axis. Here are a few examples and a video of my printer:

I have spoken to support and attempted a few fixes. I've both tightened and loosened the X and Y axis belts, redone the y-axis zipties (they were a little loose), tightened the bed, felt the X and Y rods for scratches or damage, cleaned all axis with compressed air, tightened the frame, ensured proper alignment of the X and Y axis, and checked all bearings for resistance. I honestly have no idea what to try next, so I'm really hoping that this kind of thing has happened before. Thanks for the help, and I'm willing to provide any extra information or images/video that may help in solving this mystery.

Found a fix, a suggestion on Reddit solved my problem. All I had to do with tighten my X-Axis grub screws (they were off by a hair).
