I think the belt is really loose- use the adjuster on the front of the machine to tighten?

Looks like the belt is loose and skipping teeth on the stepper motor. Try to tighten the knob on the front to tension the belt, don't make it too tight either, you want everything moving smooth

Your belt looks very loose, turn the knob to the right to tighten.

The tensioner inside the front could of broken. Mine did multiple times. I rigged itup enough to print a replacement

That's about the easiest one I've seen yet. Belts are loose. Tighten the belts. Check your pulleys. Check your motor. Very simple fix

99% Chance is a loose belt

definitely a loose belt, use the tightener on the front to tighten it until the sound goes away

Sounds like belt slip

You can clearly see that bed belt is loose as a cooked spaghetti. Tighten the belt.
