@gr5: i have read that I should be able to move the head by hand to find some issues and I did it before I read your answer. The Y axis (right-left) makes the noise near to the motor on the right hand side looking at the ultimaker. I haven't really understood the thing with the black blocks and the pulleys. Is there a tutorial or something? I am a bit angry, because this is the first time I bought an "out of the box" device to concentrate more on higher quality than getting the device to a working state. My brother wanted us to buy a makerbot and I wanted to support our neighbours in the Netherlands and this is what I get :(

Hey guys, my Ultimaker 2 came yesterday and at first sight I was not very convinced about the quality, because it looked like that it had been manufactured in a very fast matter. It is a tool, but at least it should be somehow "clean". The holes of the spool holder had black color parts or whatever hanging around them etc. The reason for this thread is another one. I had printed out two things and at the middle of my third print the UM² began to click. See and listen: http://www.youtube.com/watch?v=o8r9IpTRKrs I don't know where it comes from and it is annoying to not knowing that. It's the middle of the night and I am searching the web for solutions or people having the same problem. I try to find strange looking things and the only one so far is that there are only three screws under my build plate. Thanks a lot in advance guys. Sergio edit: These might be some hints: It seems that as if it is louder when the build plate is at the highest point and the extruder is working on a wider field. The clicking is also louder when the extruder is working on the first half of the build plate (1st half = the side of the spool holder etc.)
