Random Y-Axis crashes since enclosure

Hey,

I build the Prusa ikea lack enclosure for my MK3 a few months ago. After that, i experienced somewhat random Y-Axis crashes. I made sure that the bed wont hit any of the plexiglas walls, which it does not. The crashes only seem to appear when I print things that are oriantated along the Y-Axis. I printed a 2 part fillenium-malcon in 155% scale orientated along the X-Axis with not crashes.
So the bed must hit something on Y-values away from center, but still not consistently. I use a 65° heatbed cover, because i read that the 90° has clearance problems, but when using the standart one, i still get crashes. They occur about 2 times per hour. All X- and Y-Axis bearing were swapped with hgih quality misumi bearings, now the printer runs a little bit more silent and smooth but the crashes still occur. Before moving it to an enclosure, the printer ran without problems.

Can vibrations of the Y-Axis (due to its relatively high mass) lead to the crashes? Because lack tables are not the most sturdy ones and amplify the vibration. Maybe use a slab of concrete under the printer, like previous MK2 / MK2s users?
