Ender 3 v2, first layer problems

[scoutt]

Hi all,Can somebody explain this to me. I have a print that I am using a raft on, after raft completes, which looks pretty good, the very first layer of my actual print is all rippled. How can the raft be perfect and 5 layers in the print go to crap? I have good bed leveling and stickiness. I had already pulled the print from the bed as to why you see the raft not stuck to the bed.

Thank you

Without the raft I still get the ripples. I have found that turning my bed down to 50 from 60c I don't get the waviness of the print. Now why is that?

more on this, it appears the the bed was not as smooth rolling as it could be, meaning when it rolled back it was moving to just a hair so the lines would bulge into one another. Cleaned the rollers and the rail and so far it's printing perfect.
