I bought a bunch of Sunlu high flow PLA+ a while ago and up to now have not been impressed. rough finish etc. Now it does say to print at a lower temp then other PLA’s which I didn’t do. Hey, I’m a guy, "nuff said. So today I printed a few things and the finish wasn’t great so I caved in and lowered the temp by 15 Deg F and the finish came out great. Not only were the rough faces better the ringing went away also. I guess following instructions can work out for the best but if any of you squeal on me for saying that well, I know where you live.

We won’t squeal 🙊 In a perfect world, we’d all be doing full filament calibrations for every new brand and colour we buy. But who has time for that in this hobby? 😉
