Suggestions for getting rid of a bad unit

OK, unfortunately it seems you have 2 bad axis, X and one of your Y axis.

What machine size do you have?
Take a lot of photos and videos about the travel.
I would suggest to check if the two Y axis have the same travel way, because you wrote about a bump sometimes when it travels.

I would do the same with the z axis and would try to pair the defective x axis (mark it or remember it for the future) with z, and see if it helps.

The main point is, your machine should work, then reach out to support and wait for replacements.
