Noise on x axis new to me MK4S

IMG_1427

I just got a new to me MK4S that upon inspection I noticed it must have been a kit as several bolts were loose or even missing. But I have a noise which I believe is x axis related which you can hear in the above videos. I adjusted the belt tension but no change. It seems is is a vibration within the extruder assembly. Any ideas? Thanks in advance.

Hi,

The movement of the x-axis belt is really strange. It should not be moving like that, is the bearing aligned correctly?

RE:

Check belt is properly around both pulley's.

Check the pulley's are also properly aligned each end - the belt should be completely straight without any bend/curvature at all. Look like it's a little off on the motor side (left). Once confirmed and re-seated, re-test tension.
