I can help you develop the machine. Which Galil card do you have??
If your Drives are Analog signal inputs then you will have to stick with the Galil,
If your drive have the ability to take Step and dir then your in a little better boat.
If you want (as a last resort), you could sell your current drives/servos and go with
Sure Servo AC servos from Automation Direct, in where Mach can drive them natively,
Plus, you can set up custome accel/decel profiles in the Drives themselves.
I have emailed you as well.
