I haven't had the time to look through the whole video but jumped a little bit and might have missed something important.

It sounds like the x-axis stepper misses some steps (listen at 2:33).

If possible it would be great if you uploaded a new video with better sound: No radio and camera placed closer to the stepper motor and away from the fans to pick up the stepper sounds better.

The missing steps can be caused by wrong adjustment of the drivers causing less torque, friction in the belt setup or sliding bearing or the hot end hitting filament sticking up. It could also be caused by the pulley being a little bit loose.

Another cause could be a bad connection with the x-axis optosensor...
