something loose, tend to believe in the toolhead, loose nut,bolt, etc. Or frame bolt, xy joiners and belt is walking up/down somewhere, should see belt marks

your belt def needs replacing but first check why you have the marks on the smooth side of it and the lowet belt looks smaller? or it is the video?

its just the video. belts are the same size is there a guid or anything to trouble shoot this? when I bought the machine it was already built so i haven't gone through all the steps on how to build it

so, if you have only one peak the belt is rubbing somewhere. In the last picture case is the upper belt. For the moment leave the rubbing belt problem as it is less worse. Focus on the peak at 125hz, that peak is generated by vibrating toolhead most of the cases (loose bolt, a part broken in the eva carriage, x rail bad if you ever crashed the hotend in the bed) or a loose idler stack. do the shaper calibrate before changing anything and print a test part

then go back and work on this so, if you have only one peak the belt is rubbing somewhere. In the last picture case is the upper belt.

seem like the vibrating is coming from the Y carriers. i might have to lube them up
