Well as luck would have it my Chinese spindle controller is on its way out. I thought I would take this opportunity to upgrade from my parallel port to a USB and run a more current version of windows. I've been looking online but haven't really found a suitable replacement. Some costing more than my current machine. I tried looking for a newer Chinese version controller box but it seems that they are only bundle with the CNC. i was hoping that you could suggest a replacement for my current Motion Controller.

The following is my current configuration.
3020 Chinese CNC
T-D Spindle motion controller with parallel port
Mach 3
Window XP

Thanks John
