Adjust print speed for overhangs

I've found that slowing the print speed right down produces the best overhang results, however printing the entire print or relevant layers at such a slow speed is pretty inefficient. By creating a setting that would allow users to adjust the print speed depending on the overhang amount would greatly improve print quality.
Most of the community uses additional cooling fans to overcome overhang curling or sag, but this seems unnecessary when this setting could solve this.

The software would detect the overhang amount for each section of every layer, and when the overhang exceeds X amount, it would slow the print for that particular section of the layer and then continue at it's original speed after the overhang is printed.

Good idea.

As a workaround for the time being, use multiple print processes to adjust print settings for any given section. So for the section with the overhang, use a process with a slower print speed. Then add a second process with normal print speeds... its meticulous, but should work.

Googled this today and found this topic. Disappointed to find this isn't a standard thing already. Definitely got to give this a +1.

Same and same. Get on it, S3D.
