Oh hell no - NOT cura !
1) it's crap
2) it won't work :-)
Your machine uses x3g files NOT raw g-code.
You want Flashprint
During install, tell it you have a creator pro.
It's a great slicer, really easy to use and the only slicer I've ever had any luck doing dual extrusion prints with.

And it knows you need x3g files :-)
