Ajax software is Centroid software. Just use a generic Fanuc post.
See http://www.cncsnw.com/faqCAM.htm for a few additional details.
Looking into the Ajax retofit for my old Bridgeport V2XT. Its just plain less expensive than others out there. I use Surfcam 7 and I need to know if there is or if they provide a post that works within Surf 7 to comunicate with the Ajax software in the machine. Sure as heck dont want to do all of the post process standing in front of the mill. I dont know much about the Ajax yet so any help would be good.
