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 !

    Nice cheat sheet!

    Weirdly enough, I printed at 235 thinking the nozzle was too hot and it was worse. At 245 more issues seem to disappear except less than ideal overhangs.

      I believe I was printing Overture petg around 250 on a brass nozzle, I do around 270 stainless and it’s fantastic. I run a dual 5015 satsana duct (v2 with removable ducts) and keep the fan speed fairly low which seems to help get the airflow perfect

        Four benchies

        Here is a comparison between an old benchy done with my Ender-3 and three with the SV-08
