Well I finally got my VAC III drive up and running thanks for all the help you guys were, I really appreciate it. My problem now is when I got fired up the carosole had drifted out and the shot pin wasn't holding position any more. I pushed the toolchanger off the limit switch but can't seem to regain position. The main problem seems to be the shot pin not actuating properly. Does any body have an idea. The alarm I am getting currently is 168 B.
