I've been struggling to get the Sesto Senso 2 behaving reliably with my Esprit 120ED. In the end most of the issues seem to have been resolved by loosening the draw tube.

However, this has now revealed a new issue: When imaging near the zenith I've found that the hold current seems to be insufficient to stop the focuser from succumbing to gravity (assuming the hold current is even being applied).

I notice none of the advanced parameters (acceleration, speed, deceleration, current levels & hold state) are exposed in the current INDI driver. Would it be possible to add support for them?

Many thanks for the excellent work!
Will.

I will shortly be in the same position as you, although how long it will take for the Esprit 120ED to arrive is anybody's guess at this time!
I had a look at the driver on Github, and you're right, those variables are not exposed. I think Jasem got the command set from Primulace Labs, but I don't know if they shared these settings.
At worst case, these settings should be persistent and if you change them via the WiFi Virtual Handpad then the SestoSenso 2 should continue to use them under INDI (until such time you need to change them again).

I have a question, I have the Sesto Senso v2 already, with the cigarette adapter, I notice that the usual 2.1mm power connectors don't fit the Sesto Senso v2 power port. Do you know what port I can use to avoid the cigarette adapter?

I just tried to see if the hold current settings would persist if set via the Wifi Virtual Handpad (and also via the Windows ASCOM driver) but it seems that they don't. Or at least, as soon as I connect the INDI driver it seems to reset the hold current resulting in focus slippage - especially towards the zenith.

The hold current setting definitely need to be exposed via INDI as without it focus is going to be highly unreliable with heavier setups. If I get a chance I might take a look at implementing it in the driver myself but that depends on knowing what commands are required... Anyone?

Congratulations on the new telescope! The 12VDC socket on the Sesto Senso 2 is 5.5 x 2.5mm barrel socket rather than the more standard 5.5 x 2.1mm barrel socket. I ended up making my own DC cable to run from my Pocket Power Box to the the Sesto Senso 2 which works fine. Alternatively (if you already have 5.5 x 2.1mm cables), you could perhaps get an adapter like this .

If you have any other questions, feel free to drop me a line!

In the sestosenso2.cpp file at the bottom:
bool CommandSet::loadSlowPreset(char *res)
{
return sendCmd("{\"req\":{\"cmd\":{\"RUNPRESET\":\"slow\"}}}", "RUNPRESET", res);
}

I think that relates to the "Heavy and Slow" preset, in the Wifi, create a new User profile with hold enabled, then just change the profile name "slow" to.... something,

I guess that's how to go about it...

About the adapter, yeah the supplier pointed me to that to, thanks! question answered.

I had anticipated my image train would slip, what with the clutch mechanism on the Esprit, I got the Sesto Senso because of the hold current which I thought would fix it, it definitely needs to be added to the driver.

Jasem will see this, he made the last few commits to that driver I think, shouldn't be too difficult to hack around.
