Looking for recommendations in regard to a Servo Driver for a 4-axis (X,Y,Z, and rotary) CNC router. The machine is an APE 200HD. It is about 15 years old, and I haven't been able to get feed-back from APE (Automated Precision Equipment). Basically, I need to overhaul the driver, as the daughter board is not capable of accepting the latest WinCnc upgrade. The machine has age-issues, with air lines and is probably no longer level (moved to new building five hears ago, and floor has settled. Except for the computer issues, I believe I can handle the rest.

Thanks!

Steve
