Difficulty Using 7i76e Digital Potentiometer

Greetings all,
I am trying to use my 7i76e's analog spindle speed capabilities, but I can not get the potentiometer to function.

Spindle: Makita router (0-5V fed through a 100K pot, now replaced with the 7i76e digital pot)
RPM: 10,000 @ 0V -to- 30,000 @ 5V

For debugging, I have a 10v power supply connected to the digital pot. I read low millivolts between wiper and signal regardless of MDI "M3 S#####" commands. The wiper stays firmly at the 0V end of the range, which corresponds to 10,000 rpm. Wiper to positive reads 10V (as expected). 

I had the analog output working previously with a VFD, but I can't seem to get it to work now. There seems to be a disconnect between my configuration files (attached) and the mesa board.

  
 

Any help would be greatly appreciated. 
Thanks,
Tanner Frisby

I think the spinena signal need to be high for the potentiometer to output anything.

Yeah the spinena signal is omited in hal so that will not output anything.
Remove the # in front of the line with 7i76e.nn.nn.n.spinena

Thanks for a quick response, that seems to have fixed my issue. I had forgotten to save my hal before relaunching LinuxCNC. 


Thanks for a quick response, but this didn't change my results.

Previously I had:
net spindle-enable => hm2_7i76e.0.7i76.0.0.output-04
#net spindle-enable => hm2_7i76e.0.7i76.0.0.spinena

Which turns on my spindle through a solid-state relay. The spindle turns, but only at the 0V speed. I commented the other line out to preserve it for my future self when I inevitably change my setup again.

I have uncommented the line as suggested, but I have the same results: my digital pot wiper is at GND and doesn't move when a different "S" value is submitted in MDI or when the "+" is clicked in the manual interface of AXIS

I currently have:
net spindle-enable => hm2_7i76e.0.7i76.0.0.output-04
net spindle-enable => hm2_7i76e.0.7i76.0.0.spinena
