Hi, I wondered why you were going to change the control system. I ask as I have just bought a 190VMC (not delivered yet) and wondered if I should expect problems. If you have to change then the CDE system looks wonderful, I've bought one for my Conect lathe but have not yet fitted it. if I have to change the VMC then I'll definitely use the CDE system, but I believe (based on what I've seen on the Boxford site) it should run G codes direct down the serial port.
