How do I improve from this test?

I've printed this tuning test on my VCore 3.1 400 with a 0.6mm nozzle, in PLA at 215c through a Rapido HF/Orbiter 2, 100mm/s & 4k acceleration external perimeters. PA set to 0.045 and IS active in RRF (yeah not using Klipper but RRF on Duet 6HC). Layer height 0.2mm. The print took roughly 1h, 40min. I printed a Benchy with the same settings that looks pretty good, some ringing but overall better than this larger test. I understand this model was (probably) designed for a 0.4mm nozzle so the fine details will suffer. My goal is to print large parts with good quality at decent speed, I have a Formlabs F3B+ for small parts that need lots of details. The too me most obvious things I would like to fix are: 1) Ringing 2) Branches on the rear left poles 3) Corners I would really appreciate feedback on what settings I can adjust.

The way I tune filament (printing 20 to 50 kgs a month) : print 2 or 3 temp towers (5°C steps, +/- 4 steps). 2 ou 3 at a time as I never print tiny prints on a large printer. Pick your favorite temp, don't bother too much about bridges yet With your favorite temp, drop bed and extrude 100 to 150 faster and faster, until extruder cranks Drop that max speed by 20% (Paretto's best advice) Then tune pressure advance, then tune bridging (mostly lowering bridge density and flow , to 70/90 and 65/75 (on brindging, lines should not stick to each other, but just about) Print 2 large voron cubes side by side You're done. I never tune retractions, just leaving Ratos defaults You may want to reprint your test part then, 2 at a time Extending min layer time doesn't do the trick , since you'll never print a part this way in the real life Don't forget to report all values in your filament profile
