I’m having an issue with this white piece pulling out, it has happened twice and the second time caused a lot of issues, my machines Y axis chatters when moving and looks like not aligned.

How do I keep this piece where it’s supposed to be?
You should be able to tighten that small set screw that is shown in your picture. Do not overtighten as it is just a nylon insert. Once tightened that should keep it in place. There is a video from OneFinity on the Maintenance section of the Forum showing how to if not clear.
