Unresolved X-Axis Not Working?

Hi all,
I am a newbie when it comes to 3D printing and have held myself up so far encountering issues. That ends today, I seem to have a problem with my X-Axis. I'm not sure if it's a bad stepper motor, bad band, lack of lubrication on the rails, or what. I'd love to see if anyone else has had this problem and has solved it. I've attached videos for those who are willing to help.

Are you able to slide the carriage smoothly by hand? If not I suggest removing one of the zip ties that holds the belt to the carriage so you can slide it more freely. If it still sticks then it's probably a bad bearing. Submit a replacement part request for a new x carriage.
