Ok, I found a workaround I would like to share for anyone who is having the same problem. I just hooked both servos up to the same PWM pin on the Arduino. Only downside is that I can't open the caps individually, but that's okay.

Thanks for the quick reply, Jasem. Would be possible to run two different dust cap drivers now, like "Arduino Dust Cap" and "INDI Servoblaster Cap"? How would the scheduler handle this?

Hi,

we have set up a remote observatory at my school (www.indilib.org/forum/ekos/8541-power-an...-startup-script.html) which is run by Ekos scheduler. We are using Arduino Cap to drive dust caps with servos. We have constructed two dust caps, one for the guide scope and one for the main telescope. I thought that I could add two Arduino Cap drivers to my profile (Aux1 and Aux2). However, once I have selected that drive under Aux1, it is no longer available under Aux2.

1) Is there a workaround to use two Dust Caps?
2) If so, will the scheduler open both caps when the uncap option is checked?

Thanks for any help

Hi Vin,

I am sorry I couldn‘t be of more help. Maybe I have a different revision of the EFW2. I hope you don‘t have much trouble to trade the EFW2 for the SX filter wheel.

Hi Vin,

at the moment I am running KStars 3.4.3 (I had to downgrade from 3.5.2 because the indi_usbrelay2_roof driver kept crashing). I took a screenshot to show you the driver version I am running. The EFW2 also worked with later versions of KStars, i.e. 3.5.2.

Are you running Windows or Linux on your laptop?

Hi Vin,

I am using the EFW2 with KStars/Ekos on a Raspberry Pi 4 running Astroberry Server 2.0.3. The EFW2 is USB connected via a Pegasus Ultimate Power Box (UPB) v2. The 12V power for the EFW2 also comes from the UPB. The filter wheel has run flawlessly from the first connection through different versions of KStars (staring from 3.4.3). 

I did have some problem with the filter wheel included in the Atik 6.0 and older Atik INDI driver versions. In that case the wheel was spinning and never stopped. That problem could temporarily be solved by purging the config file. Later versions of the Atik INDI driver did somehow solve the issue.

I never had a connection problem with the Atik filter wheels. 

I don't know, if that was any help to you. Maybe you could check, if any other device is blocking the USB connection the EFW2 is trying to establish. I think I had that problem with some INDI device before.

Good luck with connecting that EFW2. smile.png

Hi,

I am using the Atik EFW2 and it works flawlessly with Ekos.

Hi,

I today realized that my Pegasus Ultimate Powerbox v2 won't connect to Ekos showing a "INDI driver Pegasus UPB crashed." notice. It worked previously flawlessly and I can't remember that I changed anything. I attached a log file and hope that anyone can give me a clue what's wrong and what I can do to solve the issue. I am running KStars 3.5.2 Stable on an Astroberry Raspberry Pi 4.

Ok, I wasn‘t aware of the difference between the Telescope Simulator and the EqMod driver. Thanks for making this clear.

Hi Gonzothegreat :-)

Thanks for the reply. I understand that the telescope has to be pointed to the "regular" park position (counter weight down, looking north) precisely first, as described in your post. I just don't see how to proceed from there. Using the Kstars/Ekos telescope simulator, the telescope should be perfectly aligned with the earth's rotation axis. Slewing to a point near or on the northern horizon and setting this as new park position only updates the RA/DEC coordinates unter INDI control panel -> Telescope Simulator -> Site Management. These coordinates are also found in .indi/ParkData.xml. However, positions in the sky described by RA/DEC coordinates move with time. What I need is to define ALT/AZ coordinates here, I guess. How did you fix that problem?

Hi Gonzothegreat!

Actually I have read your and Magnus Eriksen‘s Blog on how to build a box observatory quite extensively over the last years. Thanks for the documentation of your work. It is a great project and I had students of mine contribute some parts (Roof opening, motorised dust cover, ventilation and weather station).

The link you provided seems to explain how to precisely set a park position using the hand controller of the mount. I am not using the hand controller but only KStars/Ekos. I probably wasn‘t precise enough in my post. So I think my question is:

How do you define a park position where the telescope is pointing to the nothern horizon using KStars/Ekos.

Hi,

I have built an "observatory in a box" (www.angelaschule-os.de/wie-noch-eine-sternwarte/) and hence have to define a park position where the telescope is pointing at northern hoirzon (alt = 0°, az = 0°, counterweight bar leveled horizontally) in order to avoid collision with the roof. I am using a SkyWatcher EQ6-R Pro mount. I have searched through older threats in the indilib.org forum and found that I need to slew the telescope to the desired position in the sky and set this as new park position. I have tried that procedure using the telescope simulator but found that as time procedes, the park position "moves with the stars" and changes over night. 

I am probably just missing something in my workflow. I am sure there are people out there who have done just what I need and can help me.

Thanks
Simon
