Hello, said id throw up my project to document and try get some help.
it was built in 98 and its partially stripped to check the ball screws and condition. My Plan is to use the existing hardware, drivers, spindle controller and run it from a Linuxcnc PC.
This is the Chinese BOB iv ordered. Seems to have a 0-10v output for the spindle.

The circuit diagram below if i understand correctly. The drives output a 12v step and dir. The step and Dir is connected to the collector from the transistor and the emitter to ground. The 5v output from the BOB is connected to a 2k resistor and connected to the Base. When ever the BOB pulses the 5v it pulls 12v from the driver to ground?
