Arm/belt crooked

My gantry keeps going crooked. We’ve loosened and tighten the belts. It’s like the right side gets stuck or needs some type of lubricant. Make a grinding noise

Sounds like one of your wheels that supports the gantry might be broken.

or there is debris in the wheel, on the track, or in the belt.

I got it fixed, had to loosen the right side belt a little
