Any ideas what is happening here?

Well, that looks fun.

Is this a UMO+ or a UMO with a heated bed kit?

It looks like you probably have a loose pulley on your Y-axis, so the motor is missing steps. Check all of the set screws in your pulleys and on the Y motor itself to make sure they are tight. If you try to home the head, does it move smoothly, or does it struggle?

If your XY axes haven't been lubricated recently, you may want to check and make sure they are; the motor can miss steps if it can't move smoothly.

Awesome overhangs though!

If you don't find a loose pulley, although less likely, check that the steps per mm are the same for both X and Y.

Thanks, there were few screws loose on pulleys. Everything works great now.
