Hey Keith,
I found that post I had a vague memory of:
The “Setting the jumper on 1-2 keeps the spindle from starting on power up” part is what caught my eye, and may or may not be the problem you are having.
Me, I had to adjust this jumper to the “VI” position:
I would be a little surprised if this has any effect while PD001/PD002 are set to 0, but it will be required anyway when you connect the PWM, so might as well do it and see if it changes anything…
