[mostly solved] Sovol SV-08: First Benchy, where do I go from here?

I was lucky to spend 4 beautiful years with a Creality Ender 3 v2 that I modded to the brim and never failed to deliver quality prints. I never had to adjust, calibrate or tweak anything regarding print quality.

I upgraded today to a Sovol SV-08 because despite its qualities, the Ender 3 is too small and slow for my current needs.

However, the print quality is definitely not there (yet). Overhang quality is bad but I think I may be able to tweak it with filament temp and/or cooling. There's a bit of ringing but I can live with it. My main issues are the large holes in the hull.

Filament: Overture black PETG, 240°C, 24min print.

What should I try?

Thanks

Edit: most issues were solved by doing the following adjustments:

• PETG temperature increased to 245
• volumetric flow reduced from 17mm^3/s to 10mm^3/s
• manually adjusting z-offset with the paper sheet method like on my old Ender3

There are still minor issues like overhang drooping and adhesion needs a bit more work but quality is now almost on par with my previous printer.

Thanks to everyone !
