Programmed Feed Rate was created by 64dodge
I have been using a pyvcp side panel that shows the hy spindle speed
with rs485 that I had found while searching through post here on LinuxCNC.

Found a few posts on here about cycle timers that I am going to
try to get working in it.

But would really like to get the programmed feed rate to show in there also.
Or some where in Axis.

Axis has a "show velocity" option in the View menu. Or is this not what you want?

Yes I messed with it this evening after work and thats what I found out.

But what I originally wanted to know is if pyvcp could pickup the F? feedrate
from the program and display it in the side panel.

I know this is past my abilities to do now but was just curious.

To have pyvcp display feed rate would require you to make a user program that put the current feed rate on a HAL pin and then connect that to a pyvcp HAL pin.

I don't know if the linuxcnc.stat() structure has the feedrate in, I think that might just contain the feed override value and the current velocity.

The F-value _is_ available as a G-code parameter: #<_feed>
But it isn't trivial to get a parameter into a GUI display.

it is "supposed" to be available in linuxcnc.stat() under settings. But it doesn't work as advertised and hasn't since the new trajectory planer. The problem is it shows the feed setting at the end of the read ahead which most of time just reads zero for the end of the file. (This seems like a bug that ought to be fixed.)

Yes, Todd that is true. It's a known bug.
