I am surprised it does that much. Looking at the code
( git.linuxcnc.org/gitweb?p=linuxcnc.git;a...65f96d6fdc3ba0#l1769 )
It seems like you need to set some parameters and possibly an enable.
You may need
setp halui.max-velocity.count-enable 1
and maybe also
setp halui.max-velocity.direct-value 1

thanks andy for your help
for spindle no problem i understand it
my problem i this halfile for max velocity

i try your solution but not work
for the first is a same and second one count=max>0 i can do anythink

and for your link
i don't understand all
is a halfile ? were is "net" "setp"

i don t know where i must go ... i try all ( my solution)

No, that was the source code of halui, I was looking there to try to figure out what was meant to happen.

The first thing I think you need to try is to check that the encoder is correctly driving halui.max-velocity.counts.

Go to machine-> Halmeter and set the halmeter to watch the halui pin (or the encoder-counts signal). Make sure that the encoder is actually counting properly.

I think you might see what you are seeing if the encoder is only working on one channel, so it will count up one then down one all the time.

Hi andy
I already do this
The encoder counts good 2 chanel
And acts on max.velocity.count (i can see the number increase) 1.2.3.4......45........ Etc but never decrease
Strangely only one way ... (+) No -
I thought a bad adjustment
The conections are good
I can see the scrolling LED output 2 (chanel AB)

Is not this way :(
