I'm still looking for the perfect retraction settings.

welcome to the forum.

well, for starters, you probably haven't seen advice on the other retraction settings as shown highlighted, because you posted in the "Awesome prints (Hall of Fame)" section of the forums.

beyond that, you made no mention what so ever of what kind of printer your using, what kind or brand of filament your using, and apparently no one was kind enough to tell you this. So please let this be your official notification. normally we would see these posted in the "how do I print this" section, "Hardware Firmware & Software help" section or even the "PrusaSlicer" section of the forum.

This information should be accompanied by Printer type, filament type, brand and potentially a project file, as all settings are specific to the model being printed. 

I can tell you right now if your printing on a Prusa direct drive printer such as an MK3 model your 3.2mm of retraction is way to much.

Please follow up in one of the aforementioned sections for further help.

Good Luck

Hi

Thank you for your response and advice.

I am actually using a PRUSA Mini + and the filament is 1.75mm PLA from 3DFilaPrint.

I will check out the link you sent me.

Thank you

You'll be looking for a long time... "Perfection" is elusive. Different filament types or even brands may require different settings. 

I am currently using Length 3.2mm and Retraction Speed 30 mm/s and results are good! I am looking for something a little better than that.

Better than good? How good is "good"? Remember perfection is the enemy of good. Little angle hairs (in particular with PETG)? You may spend the rest of your life toiling with improvements while a blast with the heat gun can take care of it in five seconds.

Absolutely nothing wrong with tweaking parameters, in particular if you're having fun tinkering! I'm just offering a pragmatic alternative—let good enough alone—, as chasing down perfection can quickly take you down a rabbit hole 🙂

It sounds like maybe you're already at the optimal setting if you keep coming back to that one and any changes are worse.

Can you post a picture of your print results? What problems do you have? So we can help you to get a better results, it's hard for us to tell you the better settings if we didn't know what the problems are.

This is easily one of the best advices I've seen. And it is so true, and hits so close to home. Thanks for the reminder.
