I know that this has been mentioned before (thanks Sam!) but I wanted to put this in it's own thread- so that it's easy to find. Here's the video of Stuart Stevens giant 5 Axis Cincinnatti mill, with EMC2 controlling the servos. He stripped out the old control, but kept the old servo amps and servo motors. This video shows the machine cutting air and Stuart doing some manual tool changes- but I think it's pretty nice.

Thanks for looking at it.
