Anyone here familiar with HIPS + ABS printing?

Work just purchased a Raise 3D N2 printer. I'm having a heck of a time getting it to play nicely with ABS + HIPS (for support structures).

Hours of perusal on the Raise 3D forum hasn't provided a solution so . . . V-Salon has to have an answer right? I mean, ya'll know EVERYTHING!

DM me if you want. I'm game.
