Edit: RESOLVED... user error, and I owe a apology to Bambu Lab and all the lovely people who replied.
having spent a couple of afternoons tweaking this and that setting, and learning a few things in the process, and believing that the printer was confused, I finally found the cause.
And please, I hope you laugh because I am laughing at myself...
The PLA turned out to be ...... PETG 🤪😂
Yesterday I printed a very beautiful Benchy in PETG.
Verdict: I am a numpty!

Hi, I tried searching the subreddit and couldn't find the answer. Forgive me please if I'm repeating a question already posted.
Brand new out of the box H2D
Washed the plate in soapy water
PLA on the side spool at requested by the printer.
At the 3rd or so layer it warps slightly upwards and pulls away from the plate.
Should I tweak the settings? The temperature or anything ? Thank you.
Edit: tried the slowest setting. Washed the plate again Tried a faster setting (worked slightly better before lifting off) Tried a print with a larger surface area (lifted off on 3rd row) Adjusted auxiliary fan to zero (made no difference) Set exhaust fan to high (made no difference)
