Piece moving out of place and chatter

Hello everyone,

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?

How do I stop the chatter?

Thanks so much!

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.

Hope that helps,

Forgot to round back and say this was helpful, thanks Alex
