To reproduce focuser motor hang you have to move it several times in second. It takes about 2..10 seconds and motor stop to rotating. This is reproduced in 100% of cases
I discovered this when adjusting the motor belt tension on my telescope and moving the focuser motor in both directions from my program manually.

Found another bug with slew rate. To reproduce simply start driver and enable it (set CONNECTION.CONNECT = true)
How this bug is looks like:
After enabling the device driver sends information about property TELESCOPE_SLEW_RATE twice. First time with 0..9 element names:
<defSwitchVector device="LX200 OnStep" name="TELESCOPE_SLEW_RATE" label="Slew Rate" group="Motion Control" state="Idle" perm="rw" rule="OneOfMany" timeout="0" timestamp="2023-03-26T19:25:03">
    <defSwitch name="0" label="0.25x">
Off
    </defSwitch>
    <defSwitch name="1" label="0.5x">
Off
    </defSwitch>
    <defSwitch name="2" label="1x">
Off
    </defSwitch>
    <defSwitch name="3" label="2x">
Off
    </defSwitch>
    <defSwitch name="4" label="4x">
Off
    </defSwitch>
    <defSwitch name="5" label="8x">
On
    </defSwitch>
    <defSwitch name="6" label="24x">
Off
    </defSwitch>
    <defSwitch name="7" label="48x">
Off
    </defSwitch>
    <defSwitch name="8" label="Half-Max">
Off
    </defSwitch>
    <defSwitch name="9" label="Max">
Off
    </defSwitch>
</defSwitchVector>
and second time with different element names (1x..10x):
<defSwitchVector device="LX200 OnStep" name="TELESCOPE_SLEW_RATE" label="Slew Rate" group="Motion Control" state="Idle" perm="rw" rule="OneOfMany" timeout="0" timestamp="2023-03-26T19:25:04">
    <defSwitch name="1x" label="1x">
Off
    </defSwitch>
    <defSwitch name="2x" label="2x">
Off
    </defSwitch>
    <defSwitch name="3x" label="3x">
Off
    </defSwitch>
    <defSwitch name="4x" label="4x">
Off
    </defSwitch>
    <defSwitch name="5x" label="5x">
Off
    </defSwitch>
    <defSwitch name="6x" label="6x">
On
    </defSwitch>
    <defSwitch name="7x" label="7x">
Off
    </defSwitch>
    <defSwitch name="8x" label="8x">
Off
    </defSwitch>
    <defSwitch name="9x" label="9x">
Off
    </defSwitch>
    <defSwitch name="10x" label="10x">
Off
    </defSwitch>
</defSwitchVector>
I don't know is this good or bad but my program stores first list for user selection and fails then trying to change this property

Which program are you speaking about?
Slew rate has slightly changed in OnStep and SWS and has not been catched by Indi for the time being, it is noted and will be investigated.
What is the effect on telescope control?

For the time being I am working on
'Degrees pas meridian' fixed and testing
'Meridian Autoflip' Fixed and testing
'Overhead Limits' Fixed and testing

Done and ready for testing
It is on my github github.com/azwing/indi

I'm talking about my new INDI clent: www.indilib.org/forum/clients/13006-astr...strophotography.html
It's in active development now so I notice all sorts of oddities in the work of INDI ))
What property name should be used:
LX200 OnStep.TELESCOPE_SLEW_RATE.0
or
LX200 OnStep.TELESCOPE_SLEW_RATE.1x
?

It looks like warkaround is to use data from first defSwitchVector and ignore second defSwitchVector. I will fix my client

I found why it was defined twice and should be solved in the version on my github.com/azwing/indi/tree/master

it was a race between OnStep overides for sleaw rates and indi default ....
Nice you discovered it.

Hi Denis,

I tried many times with different methods to run in and out the focuser but I could not find motor stopping working.

I did it like that:
Open control panel and entering different values in absolute position for moving
and after I tryed using relative position and also no hang-up

I must admit I use OnStep 4.24m

Last update:
Fixed Slew Rates updates

Alain, It is possible that this is just a feature of my OnStep device.

Yes it is possible, but this is the annoying side of the issue.

I tested it on a "real" bench OnStep.
A piece of wood with two stepper (RA and DEC) and another stepper for the focuser.
Additionally one BME280 and a DS18S20.
that's it.
On my Telescope I have Only RA/DEC and Focuser and it works well autofocusing with Ekos.

For some other test I use Khalid's Python Scripts which work really well.

anyhow I will continue to test and try to sort out some discrepancies that are still existing between SmartWebServer and Indi except some "nice to have" optimization features that I would not consider for now.

On the other hand I would be interested in testing your soft if I can install it with package.

Successful installation under Debian 11 (bullseye)
some points:
- I don't see where in installs in the menu, I would expect it under "Applications/Sciences/"
- It looks like OnStep Focuser is not recognized unlike in Ekos

it's amazing and promizing.
