This is my first run of the RapidChange ATC system that has just recently come out. This is my first set of tool changes after dialing it in. This unit has 6 tool positions, a motorized lid, and IR detector to test presence of the spindle nut and if it is correctly threaded on. The macro also does an automatic toolsetter measurement on my AVID touchplate in its storage location. So far this looks pretty good. Now I will move on to some reliability testing. I will do a full review in the near future.
