K1c with CFS kit now having shifting x-axis issues: prints shifting to the right, causing "cutting" error

Hi;

I have had issues with 2 of the last 4 prints where the prints shift to the right, including pooping to the right of the bin–and then with resulting issues with the printhead likely not activating the cutter in the back left of the printbed area. What could be causing this, and how to investigate/fix?

Thank you!
