Last week I had to remove the pipe in this picture to fix a wire that broke off, now I notice there is a slight rock in the direction of the Y access on my Z access at the bearings. Has anyone had this happen before and know a way to tighten it up?
Yes, the bearings can be adjusted on the Z axis. The bearings are on an eccentric bolt that you can turn for less or more preload on the bearings. Look at assembly manual shows set up.
