Hi Roger Right on with the idea of retrofit as a second option behind repair of the existing. If the machine ran in an acceptable way with the old control this repair is usually easier and almost always faster to a machine making chips than any retrofit.
I've worked with and like/dislike features of both the Mesa and Vital boards. Either will work for you in what I imagine for this application. Vital's cards are a bit more definite purpose. The firmware and analog speed signals are on the FPGA card and the breakout boards include screw terminals. You can only read four quadrature signals but that ought to be enough even with spindle encoder and handwheel. The Mesa firmware is more flexible, allowing reading of many more encoders and there is a much more flexible HAL/firmware upgrade in the works. You'd need the 7i33 for analog speed signals and additional ribbon cables and screw terminal breakout boards. You'd be best off thinking of both machines as you make this choice of hardware vendors. One question will be the hard wired buttons like collet or chuck open/close, open/close to grip, manual tool turret rotation, and such. If there are a lot of these you may well need a second path into the EMC to handle them all. Lathe threading works on the systems to which it has been applied. You should not have a problem with threading speed as long as you read spindle angle and index pulse from the card you choose rather than from a parport. Distance To Go is in there but Constant Surface Speed is not there yet.
