7i73 Potentiometer Feedoverride doesnt change in realtime

Hello,

i have Linuxcnc 2.7.14 on Debian 9 stretch with the Kernel: 4.9.0-9-rt-amd64 x86_64 (running on Intel NUC7PJYH)

I have a potentiometer connected to the 7i73 but the problem is, the reaction is quite laggy as you can see in the picture.

this is what is in my hal file:

does someone have any idea?
thanks

Have you tried using motions feedrate override?

I'm not sure halui is real time, it looks like it is polling its inputs at a low rate.
not sure if this is affected by the CYCLE_TIME parameter in the DISPLAY section
of the ini file but fussing with that might be worth a try also

i have searched for motion pins prior but have not found any.

CYCLE_TIME doesnt make it better, only worse if i raise the number.

Did you try reducing CYCLE_TIME (to say 0.050)?

man motion

For motions pins

CYCLE_TIME was always at 0.01, then i changed it to 0.001 - didnt make a noticeable difference - and then to 0.1 which was way more laggy.

i have searched for motion pins prior but have not found any.

i ment any pins which do the same like "halui.feed-override.counts".

"motion.adaptive−feed" may work but i want to use it in the future for automatic feed reduction if the spindle is about to stall.

Not sure why halui is so laggy here, Ideally motion should have a feed over-ride pin available so its real time, and not passed through NML

Just to let you know, i have a fairly big pyvcp containing:

program time
program line
actual spindle speed bar
spindle load bar
commanded spindle speed bar
reached spindle speed led
combined feed bar
coolant led
touchprobe led
tool clamped led
tool air blast led

that may affect the ui performance i think

hopefully someone can implement motion feedoverride pins, that would be really nice
