This is a Gen 4 control box that I have been using for the past few years. It is quite reliable and never has had many of the USB problems that you see here on the web. It is complete with three Gecko drives and the USB input board. I also will include the circuitry for operating your Router or Spindle from the program. It consists of the wiring shown on the Shopbot site connected to a relay with two sets of dry contacts. In my case it turned my spindle on and off and the other set of points started and stopped my dust collector. $600 packed for shipment, you pay the freight or UPS or whatever.
I did not clean this up. It just has been kept clean and protected since new.
