I did some deassembly and the noise only went away after I took out both long x axis belts. Taking out the short x axis motor belt didn't seem to make any difference. The machines is about 3 years old and it's in heavy use in a university but the belts don't seem to be worn down and there was minimal rubber particles in the corners, so it's somewhat odd why it suddenly started making noises. The printer is already in pieces but we have several others so printing the alignment sticks won't be a problem. Can't find a belt replacement kit anywhere easily but the teacher probably can get them from the place we bought the machines.

I took the whole printinghead assembly off and I get the same noise by just moving the x and y belts so it's definitely them. I'm not even going to touch the z axis until I get these sorted, if I can. I have enough problems already. =D I'll first try to loosen each belt separately and see if I can isolate the noise maker or if it's everything...

One of our S3 printers started making noises last spring and we saw that the Y-rod had some bad grooves in it so we decided to put on new Y-rod and bearing. I just did that today (school moves slooowly during summer) and it's still making noises. Now Y is much quieter but X is making a racket. All other rods seems to be okay and I can't see any grooves so nothing is obviously wrong. Any ideas what I should try next? Here's a short video of the noise the machine makes.
