    Having just installed one of those BoBs to replace the old one on my lathe, I can say with confidence that the 12v and 5v grounds are commoned! Therefore the 0-10v output is not ground isolated. Some years back I published on here a simple circuit to take the PWM output, isolate it with an opto-isolator, and smooth it to generate the 0-10V needed by Sprint type drives. A bit of searching should bring up the post.
