problem with haas lathe milling with c axis

[hbosYHPY6]

hello,

I have a question about milling on a Haas ST20Y lathe. When I want to mill a gear with the y axis, it goes well with the first tooth. After milling the first tooth, the milling cutter goes back to its starting position, and the main spindle suddenly starts to rotate 360 ​​degrees and then comes to the starting point of the next tooth. This rotating movement of the main spindle costs extra time. Can I turn a function on or off when posting my program to prevent this, so that the spindle does not continue to rotate?

In the Post Processor properties, there is the 

Optimize C-axis selection

Option. Turn this on, and you should be good to go.

This makes it harder to start at any operation halfway through the program, but indeed it saves a lot of time in some cases.
