Feed rate value for AXIS was created by FiliP

I saw small widget on main screen gmoccapy, where feed rate is calculated and shown.

I want do the same for my AXIS and gladevcp widget, but i cant find anything about how it is done, on the web.
I looked into testing (sim) configuration, but get no luck.

There is no HAL pin with current FEED.

Any hints?

You can get the velocity of the cutter from the pin

motion.current-vel

This is in machine units per second so you would have to scale it to what you want to see.

Hi.
My feed rate slider dont work since i bought XHC HB04. Can anyone help me with this situation? :dry:

We have this:

pendant:feed-value
                         <== motion.current-vel
                         ==> xhc-hb04.feed-value

Before HB04 i was using this:

loadrt	mult2	count=2
addf	mult2.0		servo-thread
addf	mult2.1 	servo-thread

setp	mult2.0.in0	60
net	ips-in1		mult2.0.in1				<= motion.current-vel
net	ipm-out1	gladevcp.hal_feedspeedbarcurrent	<= mult2.0.out
setp	mult2.1.in0	60
net	ips-in2		mult2.1.in1				<= motion.requested-vel
net	ipm-out2	gladevcp.hal_feedspeedbarset		<= mult2.1.out

Now i have this error:
rpanel.hal:14: Pin 'motion.current-vel' was already linked to signal 'pendant:feed-value'

I'v tryed using pendant:feed-value, pendant.feed-value or xhc-hb04.feed-value instead motion.current-vel, but this dont work. I cant get through this...

A pin can't connect to more than one signal.

But, that's OK, just use pendant.feed-value everywhere you want that pin value. In this case

net	pendant.feed-value		mult2.0.in1

Yes, i knew it but didnt know how to use this knowlege So i can have one pin to signal, but one signal to many pins... So i must know what is signal, what is pin... Thank you.
