I just bought a brand new Ultimaker 3 and everything seems good besides an odd knocking sound whenever I'm printing. The sound is only present when I'm printing, not when I move the printing head manually. I have tried to check for loose parts but everything seems tight and it's impossible to locate where the sound comes from.

Here is what it sound like:
Has anyone experienced something like this? Or can an official Ultimaker supports person please give a hand here. I paid a lot of money to be able to print without issues.
