Help noise from UM3Ext

Hi all.

I can't figure out how to fix this.
I keep hearing an annoying noise that seems to come from the seat belts or seatbelt pads, but I cannot identify it.
I've lubricated the axles and tightened the belts but it doesn't work out.
Do you have any ideas?

 

 

Thanks

I find it hard to distinguish from the clip but a few things that come to mind that can be generating some noice/sounds; did you check if none of the belts rub onto any of the pulleys? Are the rods aligned? And is the noice mostly in either X or Y? Sometimes when one of the bearings inside the head needs to be replaced you can also a bit of a sandy/grindy sound. Hope this helps!

Thanks SandervG.
I'll try to align rods.
