Microtouch focuser refuses to connect : Resource busy

I would have bet so indeed, given the context. Let's try to find the problem. Am I not mistaken that you had the same issue one year ago and that it was an incorrect baud rate? (is the Andromède observatory yours?)

I was pretty sure that it was the same issue as my Moonlite though. I suspect it has to do with a timeout or perhaps an interval between actions that is too short. Most of the time the Moonlite driver will fail to connect on the first attempt. When the error appears, I can press "connect" again and the driver successfully connects. I don't remember if I ever needed to try this multiple times though. Could you try this method repeatedly to ensure your situation is different?

Also, would you happen to have an old log from the time the connection was working? I can see in your last log that the very first command, the handshake, fails. That's a 1-byte command (incorrectly appearing as "0xffffff8d" in the log, that's 0x8d actually) that tries to read 3 bytes. No clue if that could be related though. Write is successful (no WriteCmd error in the log), read is successful (no WriteCmdGetResponse error in the log) but content read is incorrect.

If we hit a dead end, I'll raise the priority on my investigation of the Moonlite issue on my setup...

Unless unless unless it is the position issue that goes over 32768 ticks? The Handshake function is managing a signed 16-bit, while the GetPosition function is managing a 32-bit. Could you try to move the focuser manually until its reported position is under that value before connecting?

No, position is coded with 16-bit. But ack will only succeed if position if positive.

No more ideas for tonight :)

Eric,

This is true that I had the same focuser connection problem in March 2018 (bugs.kde.org/show_bug.cgi?id=392148) and it got solved "by itself" through an unknown way. And now the problem comes back again ... through an unknown way .

My observatory is not Andromède but I published it as My Igloo in Laval (but I'm unable to give you a link to it).

I checked that the baud rate is 19200.

But You found the bug :
"Unless unless unless it is the position issue that goes over 32768 ticks? The Handshake function is managing a signed 16-bit, while the GetPosition function is managing a 32-bit. Could you try to move the focuser manually until its reported position is under that value before connecting?"
If I set the focuser manually below or equal 32767 : the focuser connects (see attachment)
If I set it above 32767 : the focuser doesn't connect.

There is definitely a bug in the INDI driver due to a integer/longint definition.

A big bravo for having found the bug !

Then we'll need to have a drink together at some point. I'm located ten kilometers north of Rennes :)

Can you open an issue on the INDI github for this? I can do that at some point if you want.

I am trying to determine if there is indi support/driver for the microtouch focuser by starizona. judging by this thread there is a driver, albeit with some problems, I dont see the microtouch listed in the list of devices ?? I have a celestron C8 using hyperstar, and the microtouch is the only solution I have found for use on a sct using hyperstar.

also the astroimager mac application does not list microtouch as an option for a supported focuser. stark-labs does have a free mac app to run the microfocuser, and does list it as supported by nebulosity on the mac os, but I have not tested itas I have not yet purchased the microtouch focuser.

thanks

Ok great thanks. How do I get the driver, as it is not listed in the devices section ?

I am currently using astroimager . I was thinking that if I could confirm there is an indi driver for the micro touch focuser, Peter should be able to add it to the supported focusers with astroimager ?? Also, the guys at starizona are not aware of any indi support for there micro touch focuser and are hoping someone would write an indi driver for it as they like me are mac lovers. the only mac software they were aware of that supported their focuser was sky x. in addition stark labs wrote a simple mac program to control the focuser but I haven't tried it.

thanks

Hi suvowner,

1/ You'll find the MicroTouch Focus 1.1 for OS X here : www.stark-labs.com/downloads.html
This is however a very simple piece of software with which you'll not be able to do much.
The built-in driver is not an INDI driver as far as I know.

2/ Concerning TheSkyX sold by Software Bisque for $349.00 (TheSkyX alone, and then you'll have to buy all adds-on ending for around $1000) , I would really not recommend it to you because it's a simple robbery. Bisque has invented the MILKY WAY to get (milk!) yearly money from its customers : you'll have to pay an extra $100.00 every year to get the software updates.
That a joke if you consider the extremely poor support. But a good business for Bisque.
Now, if you have extra bucks....

3/ The MicroTouch focuser is beautifully supported by KStars / Ekos through its INDI driver. There was still a minor bug which has just been corrected by Jasem. Enjoy.

Regards,

ok great thanks for the explanation. So will it also work with astroimager for mac through the indi server ?? , or only with Kstars/ekos ??

i am currently running indi server 2.7.0 (1.7.0), how do I get the recently corrected driver ??

thanks

oh and I just realized was Jaseem asking me to edit my profile on post 28271 ?? when IU try t odd this I get an error message - (Class only available on Joomla 1.6)

but I am using MacBook pro 10.13.6 and celestron cpc edge 800 on a wedge with hyper star and asi 183mm pro, and astroimager.
