No Analog voltage change 7i76e

Linuxcnc 2.8, Debian 10, 7i76e, new install, newbie to Linuxcnc
1990 Haas VF1, 750W DMM AC servos
In pncconfig the spindle open loop test works. I just had to invert the direction. Speed varies according to the input. But when I start Linuxcnc, axis, the spindle direction works, but it's at full speed. There is 10V in on TB4 pin 3, ground to pin 1 and to the VFD ground. Pin 2, Spindle OUT at max voltage.
I suspect I have done something wrong in pncconfig, but internet searches haven't helped.
The Haas expects CW and CCW to actuate relays, and that works using output pins, but not the TB4 spindle enable and direction.
I will attach the HAL and INI.
Thanks!

/EDIT oops, I thought you were missing some stuff but I found it in your hal.


Try this:

#net spindle-output => hm2_7i76e.0.7i76.0.0.spinout
net spindle-vel-cmd-rpm hm2_7i76e.0.7i76.0.0.spinout

try setting output_scale to 5000

output scale sets at what inputs sets max voltage output

min and max clips that maximum.

you had it set to have maximum voltage output at -5000 , then clipped min and max above that.

I'll try it. Thanks!

Chris thoughts will probably fix it.

That helped. I can now get the spindle to turn with the plus and minus speed adjustments, but issuing an S command stops the spindle instead of changing the speed. Strange.

Need to issue m code to start spindle in MDI mode.

Idiosyncrasies of linuxcnc

Linuxcnc is somewhat sloppy in it's modes (switches modes behind the scenes) and yet rigid at the same time.

That worked. Thanks!
If I issue M3 to start the spindle then further S commands will vary the speed as it should. Thanks again!

For anyone else who has this problem, it appears in pncconfig, I ticked a box to reverse the spindle because it turned the wrong way in the open loop test. I unticked the box and that fixed the ini file -5000. Unticking the box has no effect in the machine operation. My spindle turns the right way per M3 and M4 commands in MDI.
