    Yes, sorry about my terminology, or complete lack of it. What I should do is post what I'd like to do. The attached image is of the present bob. What I'm trying to do is remove it, as I believe it's broken, along with the z axis stepper motor driver. Then I'd like to replace it with a different bob and stepper drivers. So far I've managed to draw up the diagram for the drivers, but the bob has me stumped. And I really do appreciate the effort, thank you.

    I've loaded a photo of the bob I would like to install and a diagram of how I think it might work.
    I believe the board I was referring to is the main board, and the vfd connects to that via a ribbon cable. The 3rd shot is the main board, unless that's not the right name for it.

    I think I might have stumbled on an answer after watching countless online videos. I only need to connect the main board to the breakout board if I want to control the spindle speed through the mach3 program. I just need to connect the 12-24v to run the bob. I believe I can control the spindle speed manually through the box mounted pwm.

    Yep, like this:

    Except you don't need the USB connection , just a 12-24v supply as shown.

    Awesome, that's the reply I was hoping for. The 12-24v would be more reliable than the usb cable. Now we're cooking with gas. :-)
