MK4 loud buzzing issues

Hi! We got a Prusa assembled MK4 a little over a month ago (March 1st). We calibrated it and it went fine. We loved it and the prints were super great. It wasn't the quietest thing, but we didn't know if it should have been any different. Setup worked and the guide didn't say anything about noise.. so we carried on. Now we have stopped using it because it makes a LOUD buzzing/reverberating noise and the belt is wearing unevenly. We are wondering if something is actually wrong. Should it make this noise? It is LOUD and definitely getting worse. It makes this noise when we start a print or "auto home." It's with the z axis we think? Honestly not sure, and just want to make sure we are going about the correct ways to diagnose and fix it. Since we didn't want to make it worse. It is currently on the floor with a concrete paver. Previously it was on a workbench with foam pads and the paver. Hopefully the audio clip works.

We've tried to add media twice and it won't show the audio clip that has the noise. We don't know how to make it show up.

For me it sounds like some resonance on frame. I'd check everything around frame during that, I suppose Z homing and try to find source of vibrations

Try zipping the file and then adding it to your post.
