This seems to be set in the firmware of the focuser, just as in the MyFocuserPro code. Fortunately, that is open source, so I could edit it and reload it into the Arduino.

You may be able solve your problem by changing the procedure somewhat:

1, Remove Sesto Senso
2, Hand wind it all the way in clockwise,
3, hit calibrate as That's now Zero
4. Now set the focuser position to 100,000 (i.e. the middle between 0 and max travel)
5, re-fit Sesto Senso focuser ONTO TELESCOPE THAT ALREADY IS NEAR PERFECT FOCUS,

That should give you enough room (+/- 100,000 steps).

Yep, I have no idea where the middle is,
when using the focus routine it doesn't give you any numbers, so you have no idea how far its moved, 

I used to be able to set the focus position above 200,000
I've definately manually entered 1,000,000 on a earlier version of kstars

I've been using my scopes with Kstars for over a year without this focus limit problem
this is a new problem after the last Kstars Update
I suppose I could try and downgrade Kstars.
I'll google how to do it.

Thanks for the help everyone,
I'll update if I find a fix that works.

Anyone know how to edit/build/install INDI Drivers

The way I read this, the problem lies in the Indi driver.  It seems to overwrite any input and sets the maximum position to 200,000.  
I think you could just add a 0 to that, so now the maximum position would be 2,000,000 and then recompile, as Andrew suggested.
Jasem, am I interpreting this code correctly?  I had to change the Arduino MoonLite code at the equivalent position to solve my problem with the max position.

 


 

In my earlier post, that I mostly retracted with a strike through, I did exactly that. Added a zero to make it 2,000,000 and compiled a version that should work on a raspberry pi 4, 32 bit system and attached it for him.
I'm not sure if it is compatible though, so he should backup the original driver first..

Hi, Thanks for the driver, I just tried it, but my OS is 64Bit Ubuntu, so it didn't work, what software do you use edit the driver files?

Thanks, Darren

Oh, I can make a 64 bit version too. Give me a little time.

OMG , that's very generous of you to spend some of your time on it, 
Thanks very much.
Darren

Give these a go, Built for Raspberry Pi 64bit.
*Backup original drivers first.
 

Hi, sorry, my system doesn't recognise the driver.
here are my 64bit driver files if you can edit them?
No worries if not, thanks for your help.
Darren 

No they can not be edited in that way. It must be recompiled from source.
I do not have the resources to make a version compatible with your system.
Either request and wait for an update to the driver, or look into compiling it yourself.
It's not too difficult to do yourself and can be handy to know how in the future.

No worries, thanks anyway, I'll hit google to learn how to compile indi drivers tomorrow.
be handy to know,
I've only ever compiled 1 program, it's a skill i should learn anyway
Thanks, Darren

Darren,Here the Indi Driver files for your SestoSenso compiled on AMD64.

Let me know if they work for you.

Jo

Here now the drivers with the Max Focuser position edited to 2,000,000
