All I can say is wow. I will have to go check the settings if they need to be more specific. But I downloaded the new Arachne Software yesterday. Since that time, I printed a Water Tower and a Raspberry Pi case. With this update, I have had no under extrusion, stringing, and no blobs, that I have had in the latest stable version of Cura 4.8.
This is the first time since upgrading to a direct drive (which has given me slight headaches since June/July) that I am a thoroughly happy Ender 3 Pro consumer again. I'm really tempted to run a lithophane print on this and compare it to the one I just printed for my wife, but first I have to finish printing the water tower for my wife.
Keep it up guys.
