I have a Cincinnati Arrow 500 and the control computer is not working any more. The servo controllers in the machine have an input for an analog control of +10v  to -10 volts. What methods are available for Mach3 to to control a system like this.

Thanks,
Paul

DSPMC/IP is a great option especially if you need lots of I/O. I have 2.

Kflop w/Kanalog.

Galil. I have the ISA board and a USB 2030. Neither is running as of yet

Mesa(under devlopment) I am doing some testing for Smurph.

YAPS10v is a step and direction to analog converter.

It all depends on what you need and what you want to spend.
