Loud vibration noises while printing
Hi everybody, I am encountering loud vibrating noises (see movie attached) and have no idea how to get rid of them. I checked all screws and greased all rods. The belts appear to have the correct tension. The noise seems to come from the print head area, but I am not able to localize it in a way that I can nail it down to a single piece. It started some time ago, and I do have the feeling it is getting worse. The print quality seems not be affected, though.
Does anybody know what I can do? Thanks a lot in advance from me and my neighbors...

I think the .mov File is not working:

Update: I think I solved at least part of it. Both belts were too loose. Prusa´s belt tuner worked wonders. What a great tool. The heatbed still shows vibrations. apparently they can be reduced to zero by pushing down the front right latch. All screws are tightened, though. Not sure what could be the remedy here...

lubricate the metal rods on Y-axis.
We will do what we have always done. We will find hope in the impossible.

Thanks for your reply! That was the first thing I have done. Would a replacement of the bushings help? Or maybe take them out and put some lubricant inside? I could imagine there is some wear. They have about 1.500 hours on the clock…IMG_4512

It will make them run a bit more smoothly, but no great effect to be exspected.
- better is to analyze precisely what the cause of the vibration is.
- you can loosen 1 screw of the Y-motor, that way you can turn it about 30 degrees. just enought to loosen the belt.
Now you can push the carriage forwards/backwards and check if there is resistance, obstruction etcetera. (probably not, unless you push is in a skew direction.
- now with the belt loose, give the printer a command to move in Y-direction. The motor will run free and you can check if that gives the vibration. (more likely, because the step motor does not move smoothly but (as the name says): in steps. What can give a lot of vibration.
compare it to the noise of the other motors when running freely (you can also loosen a screw at the X-motor so it runs free.
- compare them.
My machine stands on:
- a big wooden plate (bread board)
- below the plate it surfs on squash balls
- below the squash balls is a marmer tile (about 8 kg).
- and at night it runs in an enclosure.
We will do what we have always done. We will find hope in the impossible.

Thanks, I will give it a try!
