I guess the encoder "phase-Z" is the same as the index. 

Yes.

I also don't understand why I immediately get the "spindle not turning" error when executing a g33 or g76. 

Did you try adding - in front of scale value in the ini file, or using "calibration" from the "machine" menu?

Do you have a M3SXXX or M4SXXX command in your gcode?

Because you will get "Chosen spindle(0)  not turning in GXX"
error if not...

Oh wow, yeah, I forgot to put in the m3sxxx gcode before the g76. 
Thanks for your help guys!  Sorry for the silly mistake

No problem, It looked like all the low level stuff was right so gcode
was the next thing to look at.
