Algorithm to avoid oozing problems in dual extruders [3D Printing]

Hello to everyone,

I'm an engineering student and this is part of my degree project. I'm glad to share this algorythm with all the 3D community. As well as they have done with all information needed to make a 3D printer, especially RepRap community. Thanks to them, me and a lot of people around the world have been able to make and enjoy our 3D printers.
I hope you like it, thanks for watching.

This is a calibration piece for dual extruding, shown in the video.

Note that the wall is generated having into account the offset of my dual extruder. So if you copy and paste the this G-code, you should change it and adapt it to your extruder offset (only the wall generation in every tool change).

3D printer: Prusa i3 with double extruder upload
Slicer: Slic3r
Firmware: Marlin
Host: Repetier Host


This is the algorithm:

Hey guys, as I already finished my 3D printing project, I share it with the community as well as it helped me to do all I've done. 
Here it is the link to all the documents:
