The correct answer from the Haas website is:

"The Spindle Orientation option allows spindle positioning to a specific, programmed angle, using the spindle motor and spindle encoder for feedback. This option provides inexpensive, accurate (0.1 degree) positioning."
Gabe,
Not sure if you are disagreeing with me or not, but the "spindle orientation" option does exactly as you have described.

Repeat rigid tapping does not require the "spindle orientation" option to work.

Now if you are talking about starting a thread at a specific programmer defined angle, then yes you would need "spindle orientation".

But to have the ability to go back in to a tapped hole merely requires repeat rigid tap to be turned on through either settings or parameters depending on the machine.
