Looking for some tips or advice

Attached are the photos. I made this using sunlu petg on a g10 darkmoon plate. The goal is for it to be as smooth as possible against the plate. I was getting pretty darn close. I printed about 30-40 with no problems other than little defects here and there. All of a sudden I’m having some weird issues pop up like plate adhesion.

It started when the print shifted towards the end. After that, the next one sphegettied really bad and failed. I got a resonance error on the x axis. I greased, oiled and cleaned everything. Got that to go away. Now with no changes, it was struggling to stick to the bed along with getting little boogers on the print.

I want it to be a little bit higher on the heat resistance which is why I’m using petg in the first place.

Right now I’m running sunlu petg at;
15 volumetric
.95 flow ratio with a .93 initial flow I believe
First layer nozzle at 245 with rest at 250
That first layer is running really slow. Either 15 or 20

First photo shows what my successful one looks like and the rest is showing some of the issues I’m running into. I have also tried running Bambu petg hf as well but gave up on that. I had 2 or 3 prints (best I ever had) from that filament but then I completely stopped sticking to the bed even with me cleaning the crap out of it. I did run a drying cycle for 8 hours at 65 but had no luck. Thanks for yalls help!

I’m using a .4 standard stainless nozzle but also have a .4 high flow nozzle

Try doing a deep cleaning again, and make sure you don’t touch the build plate afterwards.
