I can't see anything wrong with the wiring either. Do you have a circuit for PWM to Analog that I could build.
I think you'd need an extra board to convert pwm to 0-10v signal.
Quick search gave me this:

Don't quote me on this so at your own risk:
As far as I've seen before the 0-10v analogue output from bob goes to P2 and the ground goes to P3.

P1 is a +12v supply to the pot then the pot regulates it through to P2 controlling the speed.
That's how it looks on the 350w machine diagram.
