Oh forgot to say, the rear turret looks like it will be fairly easy to integrate, the way it works is a lock pin is pulled up by hydraulics, this then hits a limit switch which energises the hydraulic rack which then indexes the turret. There are a number of limit switches which then tell the control which tool the turret is at depending on their state and thus the indexing will continue until the right sequence of limits is hit for the chosen tool.
The front indexes in the same way, or would if it was all complete.
