Adding Feed Rate (IPM or IPR) to the lathe screen

Is there an easy way to get the feed rate to show up on the screen somewhere? (old 2.7x version)
For various reasons (I use some css and when it's working well I'd like to know what combination of rpm and feed it's actually using) I'd like to see the actual feed the z-axis is on my lathe as it cuts whatever given diameter. I've got a add-on panel showing the actual spindle RPM so although not as straight forward there should be a way of showing the actual FEED of whatever axis. Since somewhere in there should be the pulse rate of the stepper I think it might be available or would I need to have an encoder on that motor/ballscrew and calculate out the feed that way ???

With 2.7 i have used this pin. It needs multiply by 60 for feed per minute


motion.current-vel

current velocity in user units per second


example HAL:

setp   mult2.0.in0   60
net velcalc   mult2.0.in1   motion.current-vel
net cur-vel   mult2.0.out   pyvcp.feed



actual linuxcnc stable has pin

motion.feed-inches-per-minute

Thanks. I'll see if I can get that to work. I keep thinking it's time to put together a new computer and move up to 2.9 but when it's working it's working.

(Slowly gathering parts for a cnc router running 2.9.x so maybe it's time to get them both at the same "level"

Thanks again
