Noise after belt tensioning (damaged bearing?)
As some prints where off today, I checked the belt tension and it was way to low (~70 Hz). So I tightened up the belts and tuned them back to 85 Hz. Now I have a strange noise which sounds like it comes from a loose screw or a bearing. It is really hard to locate.
Anyone has an idea or run into the same problem?
Thanks

It's the X axis motor 🙁

I can't read your video, but if you're sure it comes from a motor, try to reach Prusa support to ask for a replacement. 🙂

A replacement is already on the way from Prusa.

I've replaced the X-axis motor today. Here is how you easily reinstall the pulley on the new motor: https://www.printables.com/model/1236389-core-one-x-axisy-axis-motor-pulley-assembly-tool
