A1 Mini - Second layer issues

Hi I’ve been having recent issues with what looks like the 2nd layer on almost all my recent prints is digging into itself.

Initial layer looks like it’s going down clean but then the 2nd layer looks like the nozzle is digging into the print. Thought it might have been the modifications I made to a model but just went back and tried to print something that I’ve had a 5.5/6 success on and it started doing it on that print.

I have seen the comments about the loose screws and will check those after work.

Here is the link.
