Print bed hits the frame  

Print bed hits the frame

I have 2 identical Prusa mk4 printers. The printers have worked brilliantly for 67 print days. Now, however, the y axis of the printer catches the frame. collission happens when I print a large and heavy piece. Print bed hits the frame. Here are two pictures. One is from a working machine and the other is this faulty one. Whether the rod is possibly bent? Has anyone else had this problem? what could this be due to?

RE: Print bed hits the frame

Hi, have you managed to solve this yet?   I'd suggest there maybe something missing from the bearing mounting,  maybe the rubber shims have not been fitted correctly on the lower one?
