Thought I would share the plugin I've been using with Cura.

It adds the ability to directly generate the velocity extrusion gcode I've been using for this project since the beginning, and now it's simple enough for the average user to pull off.

Since velocity extrusion support never got merged into the main branch for Slic3r, working with it has been as problematic as building Slic3r from source can be.

Since it seems unlikely Slic3r is going to come around to using this any time soon, Machine Koder has released the same modifications he originally made for Slic3r as an easy to use Cura Plugin. No more compiling from source required.

Happy days.
