Yup, just found it.

This should work-ish

loadrt conv_float_s32
addf conv-float-s32.0 servo-thread
setp halui.rapid-override.direct-value 1
setp halui.rapid-override.scale .038
net jog-override-scale hm2_7i76e.0.7i76.0.0.analogin0 conv-float-s32.0.in
net jog-override-anal conv-float-s32.0.out halui.rapid-override.counts

I've got this, but it's on my PI inside my emco... I'd swear I sent it to
you a few weeks ago. Check the Facebook chat.

I thought that Axis knew how to update the sliders to reflect the rest
of the system, but I haven't used Axis for quite some time.

Did the actual overrides work?

I have a display of the values in milliseconds and combined motor speed 
control cobbled up out of pyvcp, to run both halves, the on time and off 
time for a teeny little peristaltic pump that controls the mister. A 
cobble job for sure, but it does exactly what I ask it to do. Uses a 
oneshot you can ccontrol both on & off times of, enabling the axis 
mister checkbox turns the air on and starts the oneshot, and the oneshot 
on time bumps the pump for a few milliseconds about 3x or 4x a second.

Takes about 4 hours to use up an 8 oz coke bottle of about 5% kool-mist & 
distilled water. The pyvcp module that feeds the display is analog, and 
could be used for your servo trim signal. The module itself has up and 
down arrows you click on to adjust. 5ms on, 250ms off is enough to keep 
the tool and alu its carving wet, cool and cutting clean while the 
spindle motor is doing 17k rpms on a rebuilt 6040 cnc mill.

Hey Andy.

I was playing with most of those halui pins last night.  They all didn't
work.  Or it's possible that they are just not updating the axis gui
sliders to reflect pot value

Have a look at the hallui pins. I think that they include what you want.
