Clicking noise PSU after V3.0 update on Ender 3


Recommended Posts


since I updated my Ender 3 with the skr mini e3 V3.0, I get weird clicking noises from the PSU. This only does happen if the hotend ist heating.

I am very thankful for advices or tips. Do I have to replace the PSU? Maybe with an MeanWell or similar?
