I wrote a plugin for Cura!
The aim is to keep your prints in the "golden temperaure zone" when feed speed is reduced by the cool feature. This allows you to use high speed settings for the first layers of tapering objects without them overheating and sagging when printing the details.
The speed was ramped down from 110 mm/s to 31 mm/s by the Cool feature during this print.
Check it out at http://wiki.ultimaker.com/CuraPlugin:_Flowthermostat, I am really keen to get feedback!
(For some reason the wiki does not show new plugins unless you are logged in at http://wiki.ultimaker.com/Category:CuraPlugin)
Back to coding, or perhaps sleeping , we shall see...
Happy printing!
