I've seen some request for features that might be related with this topic though I haven't find one specifically focusing the following.
I often print some parts, with say 150mm x 180mm, which are not very complex but might have, say 20 holes with diameters between 3 and 6 mm.
I could easily print such parts with speed over 80 mm/s wasn't for the mentioned small holes geometries that when printed over 60 mm/s will induce very strong vibration on the build.
I know I can reduce the outline speed but that will delay any other outline in the build, which is significant if I am printing a part that size with 2 or more shells.
There might be some workarounds, like manually editing gcode, which honestly I believe is not the way to go for many reasons and one more
Having said this, I would most welcome a feature kind of "Adjust printing speed for layers bellow..." , say "Adjust printing speed for perimeters bellow..."
Thank's for your kind attention reading this.
Best wishes.
