Idle noise

[roxi 0]

Hi there, 

We have an Ultimaker 2+ in the lab and it is making quite some strange noise even you just turn it on without doing anything. I recorded an audio (in the attachment) and does anyone have similar experience before?  Is there anything I can do to get rid of the noise? 

 

It started making noise after a failure printing (pretty much like the Spaghetti monster in https://ultimaker.com/en/blog/23426-seven-3d-printing-horror-stories-and-how-to-avoid-them), although I am not sure whether this is even relevant. Right now the printer can still print but with the noise of course. 

 

Any suggestion would be great! Thanks!

Is your rear fan running? It sounds like your fan wires might be pressed up against the blades.

No, it is not running. That's a good point. I will check it and see what I can do. Thanks for the help!

You're welcome. Good luck. If you're still not sure after checking out the fan, maybe share a video?
