Adhesion of print to raft  

Adhesion of print to raft

I have been printing for well over a decade now, but I am entirely self-taught, so I accept that the problems I am having might be of my own doing. I have perfect adhesion during felt-layer calibration, perfect adhesion of the raft (or the skirt, etc.), but once the actual part starts printing atop the raft, I can see that the nozzle is much to high above the raft. It has moved from where it was to where it now prints, if that makes sense. Even when trying to use "Live Z" adjustments to save my prints, nothing works. This is a relatively new issue, as this printer (MK3S+) has been great to work with for dozens and dozens of prints. This happens with every file I try to print, so I know it isn't any one particular corrupted file. I am alright with hardware, but know next to nothing about software, messing with Gcodes, etc. 

Has anyone else encountered this issue?

Thanks for any feedback.
