7I76 output issue

I am hooking up a 7i76 card to my machine, and everything is working so far.  My machine is a CNC router that uses a hand held router as its spindle.  To control the spindle (Turn it on and off) it uses a GPIO controlled relay.  My problem is that I can not get the spindle on controls to operate the GPIO pins on the 7i76.  I am a total novice to this so any help would be appreciated.  Thanks

Post your INI and HAL files so we can take a look at your configuration.

Have you used halshow yet?

I have used hal meter and can determine that the signal for spindle enable is on

There is nothing connecting motion-spindle-on to any
hardware output in the hal file

Normally this would connect to hm2_5i25.0.7i76.0.0.spinena
(and the 7I76 Spindle ENA+, ENA- output would be activated when true)

It might be that you did not setup the spindle in pncconf?

I get these connections if I try:

# ---digital potentiometer output signals/setup---

setp [HMOT](CARD0).7i76.0.0.spinout-minlim [SPINDLE_0]OUTPUT_MIN_LIMIT
setp [HMOT](CARD0).7i76.0.0.spinout-maxlim [SPINDLE_0]OUTPUT_MAX_LIMIT
setp [HMOT](CARD0).7i76.0.0.spinout-scalemax [SPINDLE_0]OUTPUT_SCALE

net spindle-output => [HMOT](CARD0).7i76.0.0.spinout
net spindle-enable => [HMOT](CARD0).7i76.0.0.spinena
net spindle-ccw => [HMOT](CARD0).7i76.0.0.spindir

My only spindle control is going to be on off because the spindle is a hand held router controlled through a relay. As far as I know I have set up the spindle in pncconf. Is there something special I need to do to set it up.

If you want to use a field output to drive the relay,
you would set that up in pncconf, something like this:
(output 01 is spindle- on)

That is what I did. Is there something else that I need to do?

If you did, you should get a statement like

net spindle-enable => [HMOT](CARD0).7i76.0.0.output-01

in your hal file

If thats is there the 7I76 output01 will turn on when the spindle is enabled
