Programming a ZC helical interpolation in Esprit, and it is wanting to program hundreds of blocks as it mills around the helix? Average Z move is a couple thou at a time.

Is there a setting, or different type of interpolation that wont do this? Could this be a problem with our cad model?

I don't have Esprit yet, just having a demo part programmed, and this is a huge program file. Programming injection feed screw.
I program these screws on a 4 axis mill using Fanuc custom macros, but we are looking at a Mori NT, so the sample program is a lath setup.

I posted here instead of Esprit forum thinking more would see it.
