AC/DC adapter crackling noise

Recommended Posts

Today I heard my AC/DC adapter for my Ultimaker 2 making a loud crackling noise.

The noise gets louder the more power is used by the printer. It gets quite loud when the hot end is heating up.

I am guessing it is faulty and about to fail.

Has anybody else had this problem?

Best thing you can do is to make sure the power cord is properly plugged into the power supply. The power supplies are actually quite high quality products from Mean Well and according to a recent post by Daid, there was only one bad out of thousand (?).

But maybe you're the unlucky one. In this case you should submit a ticket to Ultimaker.

Thanks for the reply.

Everything is definitely plugged in properly. I double checked all of the connections and turned everything off and back on again.

I have also submitted a ticket to ultimaker but I guess it might take a while to get a reply.

I was just wondering if this was a common problem, and to double check others also think it's a fault.

I daren't use the printer now until I get a replacement so I guess I am out of action for a while.
