Right now I actually have my meter hooked to the aout2 and gnd2 terminals on the 7I49 with my meter hanging next my screen and keyboard, so I can see exactly whats going on.

I would test your config here, but with no 7i49 and no 7i70 it wouldn't be very conclusive. Maybe PCW can try it out?
I suspect the problem is a misunderstanding of how the enables work on the 7I49
there is really only a single common enable (enable 0)
This gates all channels
If you want a separate spindle enable, I would use a 7I71 output
I actually am not using the enables from the 7I49 though. The drives are enabled through hard logic in the machine, if that should be changed I can do that. My spindle is functioning as commanded, my slide drives are commanded from the pwmgen on channels 02 and 04 with z being 02 and x being 04. I have reconfigured my setup to put z on 04 and x on 02 and still had the same result.
No (you cannot because the pin is "owned" by the PWM gens) but you cannot wire ENA 0 to spindle enable or you will turns off the other analog outs when the spindle is off
