MESA 7i76 again another spindle out issue was created by bevins
Hi,

I am pretty sure I am doing something incorrect but it is so simple I cannot find it.
with a 7i76 card spindle, I am using VFD and using the pot interface.

I cannot get anything out of the analog out pin.

I wired the 0, 10v and signal pin but I get no voltage out of the spinout. This should be a no brainer.....

I can see the rpm change when I am upping the RPM in Axis but no output.

Warning: Spoiler!

Can you enable the spindle and have it set for some reasonable speed then read these parameters/pins

hm2_5i25.0.7i76.0.0.spinout-minlim
hm2_5i25.0.7i76.0.0.spinout-maxlim
hm2_5i25.0.7i76.0.0.spinout-scalemax
hm2_5i25.0.7i76.0.0.spinout
hm2_5i25.0.7i76.0.0.spinena
hm2_5i25.0.7i76.0.0.spindir

One way to show them is with the machine --> Show Hal Configuration -->Watch and select the pins/parms
another way is with halcmd:

halcmd getp hm2_5i25.0.7i76.0.0.spinout-minlim
halcmd getp hm2_5i25.0.7i76.0.0.spinout-maxlim
halcmd getp hm2_5i25.0.7i76.0.0.spinout-scalemax
halcmd getp hm2_5i25.0.7i76.0.0.spinout
halcmd getp hm2_5i25.0.7i76.0.0.spinena
halcmd getp hm2_5i25.0.7i76.0.0.spindir

(you could paste the above into a terminal window and run it as is)

Also check the VFDs 10V by measuring it at the 7I76 TB4 pins 1 (GND = bottom pin) and 3 (+10V)

OK, I'll check that.

I did check for 10v on pins 1 and 3 on tb4 and it is there.

Oops, my bad. Mispelled signal. All working now.

Thanks peter
