Hey folks, I have a model I'm printing in Silk PLA. It's designed to be printed without supports, but there are some gradual overhangs. I'm getting some quality issues in specific locations that I'm trying to solve. So far I've slowed down the outer wall print speed and reduced nozzle temp from 230 to 215c. I tried using some of the dynamic speed adjustments, mainly slowing down for overhangs, but they're not significant enough to be detected by the software (less than 10%?). While printing I was able to improve print quality by manually slowing down in these areas. At the normal setting, I can see the overhang tip/radius warping up, which I think is the root cause of the error.

If I slow down the whole print, it will take a lot longer, and these areas are relatively small sections of the model. Is there any way to locally slow the print speed, just on the "flying buttress" feature?

Is there a "print speed" painter the way there's a seam painter? Or some other way to force it to slow down for specific areas that are not the whole layer? Or slow for only a group of 5-10 layers?

It also gets worse on the higher layers, the first half of the model prints better than the second half (it's symmetric, so it's the same features higher up) 

Thanks for any help. "Line type" picture shown so you can see most of the overhang is not being treated as an overhang in the software.

Thanks!
