I made those changes. Now I'm getting 24v on FOR at the vfd at all times even if linuxcnc is closed....it goes to 0 when I push the cw button in axis...is this correct??
I'm getting control voltage reading in hal config but nothing at the 7i77 yet.

I would check this with a Ohmmeter across ENA5+ and ENA5- before ANY wiring is done
If ENA5+ to ENA5- in on (non infinite reading on Ohmmeter) when linuxCNC is not running
you have a damaged OPTO

Sorry I forgot the VFD inpuis are active low inputs with a pullup to 24V so yes thats correct (24V means off at the VFD)

I really appreciate this.....Not only am I terrible with hal but I'm also sick so it's hard to concentrate.

# Spindle

OUTPUT_SCALE = 24000.0
OUTPUT_MIN_LIMIT = 0.0
OUTPUT_MAX_LIMIT = 10.0 # this will limit you to 10/24000 V output = .0004V
It should be:

Did you check the (unconnected) 7I77 analog output when you turned spindle on and set a spindle speed?
