I don't want to minimize the great work done in the early days of EMC2 on that machine by so many folks, but a lot of the complexity in the toolchanger's ladder and HAL setup on that machine was a consequence of EMC2 not yet handling changers that cause the tools to move from pocket to pocket. That particular machine would physically allow holding the tool in an intermediate location while moving the carousel, which let it put the old tool back in the original pocket. Some machines (including mine) do not allow this because they put the tool directly into the carousel pocket. As of earlier today in git master (future EMC2.4) these gyrations are no longer necessary and there is good full support for these "random" toolchangers where tools move among the pockets. If we were doing that Mazak's tool changer today, it would work differently (and better.) For instance it would remember the state if you would shut it off with a tool loaded, instead of requiring a manual recovery process in that case. It would also work faster because the arm could just do a simple swap instead of the multi-step process.
