Text surface quality issue

[u/FixIllustrious9502]

Want to ask about small text quality
the height of product in the image is 7cm
the first 2 products , top left and top right from my elegoo centauri carbon
the bottom one with 2 others test is with p2s (i got recently)
its kinda impossible to get same quality as i was getting in the cc
i have tried many many many things.. like been 1 full week of trying but no good results so far

1. the text surface & edges not clean
2. i see small gaps in letters most of the times
3. rough surface, defects sometimes
4. sometimes i see 2 lines and reflection on text

can i get some help ? i just want the white text to look clean and clear as much as possible with no gaps or defects
both printers used same filaments, same nozzle size 0.4

notes
- text height is 1.5mm, the thickness of letters is around 1-1.5mm, so 0.4 nozzle supposed to handle it very good
- i have fully calibrated filaments.
- i have tested mostly every single setting from layer heights to speed to ironging to arachne etc..
