UM2 makes new kind of rattling noise, what could it be?

Dear Ultimakers,

My Ultimaker2 is already more than two years in function. I kept it in good condition, like sewingoil on the metal bars and the green stuff on the middle screw. Now my printer makes this rattling noise, while printing, and I am not sure where it comes from. Please click the link for the;  sound

I did note that the rattling sound is the most when the direction is going on the X ax. (At least; it is the ax parallel with the Ultimakerlogo) The rubber bands are tight enough and the metal bars are in good condition. Could the sound come from the right side on the back, or from the nozzlepart? Does somebody recognize the sound?

The only thing what is maybe to remark is that the rubberbands, both at the back, give rubber parts, like black dust, on the wheels. It shows that they give some kind of friction, although this is the matter already for some months or so.

If somebody knows that would be very helpful,

Hi,

You have to change your belts ! That's why you have that old crappy song.

Change the belts....with my car I never could think about diving in the machinery. Since I have Ultimakers I am getting a real mechanic....8)

Thank you for your quick suggestion
