I was doing some more testing and have discovered that the Sync command (#SPxxxxxxx!) also causes the direction reversal.

I am going to monitor how everything works under ASCOM (that seems to be OK) and reverse engineer it.

Thanks to those of you who have installed my updated version, at least we know now what the issue is but I need to work out a better way to solve it so we can have a fully functioning INDI driver that doesn't require us to continuously go back to the Sesto app to re-calibrate.

On a positive note 2 days ago I used my whole setup including the Sesto and it worked perfectly. Just finished stacking and I have a really nice NGC 6888, very sharp with lots of detail. Not bad for bortle 8.

Hi Rishi,

Nope.

Once installed, nothing worked fine as said until I changed permissions, but I did nothing more... Just reboot RPI..

I finally have a stable development environment so I can start making some changes.
My plan is to first release a version of the driver similar to the current one but ensuring it does not reverse and does the basics. I will take out the Sync function and switch off the reverse (is not implemented anyway). This will be the 1.3.
Then I will try to implement calibration in the Indi settings so we don't have to calibrate in the Sesto App. This will be 1.4.
I will put my changes in git so if they are approved the new version(s) should appear in the nightly build.
I will let you know when I have submitted 1.3 for approval.

Hi Rishi,

thank you very much! That sounds great!

I will test it when it’s in the nightly!

Hi All

The change has been merged into the source master so I assume that it will be built during the next nightly build.
The version of the driver is 1.3.

You can set the absolute position and relative position.
Please do not use the Set max position settings as this can still cause the reversal.
The Max Position should show the max that was set in the SestoSenso app, just don't change it in Indi!
Auto focus function should work without any issues. No changes there.

I will now start work on 1.4. Should be easier now I understand how to create and submit the fix. I don't use git often enough so I still need to be very careful. The instructions provided by this community are thankfully very good!

Cheers

Rishi

You're doing a fantastic job Rishi! Keep it up!

Hi Rishi,

I just tested your version 1.3 of the driver and can conform that it is working! It reads out the correct maximum position (that I have got after the calibration with the PrimaLuceLab software). Furthermore it moves to a desired absolut position and stops there. It can now focus in and focus out. I just tested indoor, so I do not know if the autofocus is working but I think it will do.

Thank you very much for that great work!

Thanks for the feedback, good to know it works.
I have done one evenings imaging and the focussing worked fine.

Has anyone pulled the nightly build for StellarMate and got the new version 1.3?

Hi all,

Have some of you noticed any overheating and buzzing sound after new driver installation?

Mine is hot as hell in less than 5 minutes!!

Thanks

Hi Paco

It should not get that hot.
There are two possible reasons but neither should be effected by the driver.
The first is the power supply you are using.
The second are the "Current" values you see in the SestoSenso app. Under the Advanced settings you can choose Light, Medium or Heavy. I run the Heavy setting as I have a pretty heavy full frame DSLR. Take a look at the Hold value. This is the amount of current used to keep the focuser set at any given position. I believe this gets set to 20. You could try changing this to 15. Remember to press the "Send" button and then the "Save Parameters" button

Thanks again Rishi!

I had that Hold parameter set to Medium/24 and I changed it to Medium/15. I have a Zwo OAG, ASI290MC, SX filter wheel and QHY183M in my train so I think that this would be a medium gear.. am I right?

It seems that now is working right without any overheating . I put the temperature probe stuck to the focuser case and is not detecting any temperature raise...

The problem now is exactly that: the temperature sensor is not read by INDI driver. Only is read when you start the drivers and connect the gear, but temperature doesn't change. I tried to keep the sensor in my hands a couple of minutes to warm it and driver is stiil at its initial read. Then I disconnected and stop the driver and restart and reconnect and at this moment the sensor read the temperature increment.

it seems that the driver (or the focuser itself) is not reading (polling) or sending any temperature data no more than at starting time.

Someone has experienced the same?

Thanks
