MK3S bed wobble/strong y vibrations
Hi,
I have a problem with rotational and slightly up/down play on the y axis. Everything is assembled according to the prusa manual, however the wobble is still quite strong. How can I fix this?

The only thing I can think of is that the u bolts aren’t tight enough?

U bolts are fairly tight but not too much. I noticed that the up and down play somehow disapeared but when I twist the Y axis there is a lot of play which causes these nasty vibrations 😐.

When I tightened my u bolts as per the instructions, they seemed tight however if I really pushed on them from the side they would move a little, so I tightened them some more until I could no longer feel that play in them. I was worried then once the printer was assembled due to the 'grinding' sound when you move the heat bed back and forth... however I believe this is normal. I've no wobble and the prints look good.
