i've got basically the exact same setup as you, other than flipping the bed upside down to use the smooth side, and having the base ender3 instead of the pro (only difference there, given we're both on mini e3v2's is the y axis rail).

a little spritz of aquanet on the nontextured side, and blocking out potential drafts can go a long way. also your first layer thickness is larger than your nozzle diameter, try bringing that down to at most 3/4ths, or 0.3 in this instance.

all that out of the way, i'm printing 230/70 extruder/bed with petg and having no real issues to speak of.

its an ender 3 in the same way that a dune buggy is a vw beetle. the only stock bits that remain are the frame and some of the steppers. it's gone direct drive, all metal, glass bed, klipper firmware on a btt mini e3v2 all running off of a mac mini with octoprint.

Defederate and preferably also defenestrate.
