the board can handle up to 3 Motors,  one Motor for the turntable and two for the lasers. But alternatively you can also use a stepper motor for the turntable and two servos for the lasers. But the software was never able to handle this. 

I am focusing more to support a second laser instead of rotating the lasers. If you need to scan a complex part, you can also change the parts position and do an additional scan. Afterwards you can merge the multiple scans with another software like MeshLab or Cloudcompare. This just works great. 

I did it with a scan of a nut. I know it is not a complex object. But this example will give you an idea, of how to scan parts with multiple scans.  

That feature would solve some of my problems concerning back cuts of different objects i want to scan.
