Hotbed noisy vibrations

Hello,

I've used my printer quite steadily for the last few months.

A few weeks ago it started making this noisy vibration. I can tell it is from the hotbed, since putting a finger on the hotbed stops the vibration.

Also, the vibration only occurs when the Y axis is close to the edge, like on the video.

Ive already tightened the screws I thought could be involved (hotbed, Y-axis belt)

Check to make sure the steel sheet is not stuck on the screw standoffs. I was pushing my sheet to the standoffs and then lowering to the bed. This caused the sheet to get stuck on the threads of the standoffs causing a small gap and the rattle. At least that is where my rattle was happening. Here is an example. Hope that helps.

Hi Pascal,

i have the exact same issue as you described it sounds like in your video and pressing the hot bed removes the resonance.

Did you find a solution? What i found is that the bearings under the bed cause this vibration/ratteling and they have to replaced. Did you replace them too?
