Hallo Zusammen,
ich spiele der Zeit etwas mit den custom-panel. (meine ersten Versuche)
Ich habe es hinbekommen das sich in Axis, auf der rechten Seite die XYZ Achse anzeigen.
Auch habe ich verschiedene Buttons eingerichtet.
Nun würde ich noch gerne unter den Achsen die Geschwindigkeit anzeigen lassen.
Nach einem Tag googeln, bin ich auf motion.current-vel gestoßen, das denke ich würde auch passen.
Nur wird eben nicht die tatsächliche Geschwindigkeit angezeigt, sondern eine viel kleinere.
Anzeigen lasse ich den Wert in der custom_panel.xml über <number></number>
In der custom_postgui.hal verbinde ich wie folgt:
net remote-mmmin motion.current-vel <=mmmin
Die Ausgabe funktioniert nur eben nicht der Wert.
Bei der axis.ngc müsste z.B. die 400 von Vel: da stehen.
Bin über jede Hilfe dankbar :)
Gruß Fritz

Hello everybody,
Playing something with the custom panel. (My first attempts)
I've got it display in Axis, on the right, the XYZ axis.
I have also set up various buttons.
Now I'd still like to Display the Velocity below the axis.
After googling day, I came across motion.current-vel, which I think would fit.
Just not the actual speed is shown, but a much smaller.
Ads I let the value in the custom_panel.xml on <number> </ number>
In the custom_postgui.hal I connect as follows:
net remote mmmin motion.current-vel <= mmmin
The output works, just not the value.
When axis.ngc should as 400 of Vel: standing there.
Am grateful for any help :)

The pin "motion.current-vel" is scaled in machine units per second. to display it in units/min you will need to multiply it by 60.

Do you need help with that?

Hi Todd, hi Tommy,
thanks a lot for the fast reply.
I found all this links, but as a beginner with to much wishes he have :), its hard to understand those.
Well i think, my problem is the scaling / multiplying from sec to min. i know a minute has 60 seconds :)
I also found a Post from BigJohnT an tried this out but still not works.

Well, short written, i don't know the command in the custom_postgui.hal to multiply the seconds.
(Sorry, for my english :) )

You would need to use a mult2 hal component to multiply the value by 60
linuxcnc.org/docs/html/man/man9/mult2.9.html
In your post gui hal something like this:
loadrt mult2
addf mult2.0 servo-thread
setp mult2.0.in1 60
net vel-sec <= motion.current-vel => mult2.0.in0 
net vel-min  <= mult2.0.out => pyvcp.mmmin

There is another example at the bottom of the this page.

hi todd, i test it and get this error:

custom_postgui.hal:19: Pin 'mmmin' does not exists

i declared in custom_panel as follows:
<number>
<halpin>"mmmin"</halpin>
<font>('fixed',12)</font>
<format>"4.0f"</format>
<bg>"#FFFFFF"</bg>
</number>

is there an error?
