I have done some experimenting in the HAL.

I do have the enable pin in my hal.

I used the net command to connect spindle-out to analogout4 in addition to analogout5 and it shows output voltage.

Still nothing on output5

I am not physically using the enable on output5 this would not make a difference would it?

I suppose I could just use output from #4 but I would like to know why 5 doesn't work....

Perhaps I should mention when I run PNCCONF that the option for axis 5 out only has one drop down where the others show 2. (I think the others have one you can change and one grayed out)

In general I would not setup a closed loop spindle for a first shot at getting this going,
but this is an issue:

MAX_OUTPUT = 10.0
ENCODER_SCALE = 400.0
OUTPUT_SCALE = 8000
OUTPUT_MIN_LIMIT = -8000
OUTPUT_MAX_LIMIT = 8000

This means the maximum output voltage will be 10/8000 V = 12 mv

Got it working.........

Cincinnati was kind enough to wire the encoder for the spindle different from the XYZ motors.

Same cable and plug but for the XYZ red and black pair is index. On spindle red and black is apparently A. B was the same as before and I did not yet attempt to reattach index.....
