Thanks a lot, will try on next occasion. Still wondering whether there is not anyway to manually update the telescope coordinates? Let‘s assume I point the scope to Polaris, so I roughly know the coordinates- and I can enter...if that was possible somehow.

I am not sure how, but after a while playing around with Ekos, the telescope coordinates did not match anymore the position the scope actually pointed to (e.g. Polaris) and what the solution coordinates suggest. How can I update the RA / DE telescope coordinates to match the solution coordinates?

Mission accomplished - the new „astro shield“ has been completed. It receives 12v input (see J4 connector = „hub“), which powers the stepper, and ccd, as well as the step down module, that passes back 5v for the Rpi. The circuit also hosts a shutdown / reset button for the Rpi and has a connector for the GPS module (3,3v).

The shield has been designed with Kicad (happy to share the files if of interest). And obviously leverages on the astroberry-diy-focuser.

Looks like my observation was not correct, the mentioned GPIOs seem to work. Only issue remaining is that the stepper always moves clockwise, despite changing direction. Maybe something wrong with the DIR pin, hope to chase down that one soon...

Hm...the more I read the more confused I am getting. The Pi 3 seems to host the BCM2837 (?), maybe the mentioned pins work ok, but need a different address, different to Version 2 or B+?

Yes, changed in the diver code, and paid attention to the numbering. According to tbis table, the mentioned GPIOs cannot bei chosen - which may explain why it did not work.

elinux.org/RPi_BCM2835_GPIOs

Is there any chance to work with these pins, still?

Helge replied to the topic 'Testing GPIOs for astroberry focuser' in the forum. 7 days ago

Found the reason, the GPIOs 13, 19, and 26 are not linked to BCM2835 - bad luck...the newly designed / printed PCB became useless :(

Hi,

I am debugging my new Rpi Shield that hosts a A4988 stepper driver. When applying the focuser driver, nothing happens. So I wanted to see whether the GPIOs are sending signals to the A4988. To do so, I put a led and resistor (100 ohm) between the DIR pin and ground, likewise for the STEP pin - instead of attaching the shield to the GPIO connector. The led is showing a very low light, almost neglectible for both pins, even without attempting to run the stepper.

Does my test setup make sense, should the led be against gpio and ground, or against 3,3V?

What should I expect when running the stepper, should the led attached to the STEP only flash up when running the stepper?

Should the led attached to the DIR pin always be „on“?

Many thanks for any support, Helge

Dear Radek,

I was reinstalling the astroberry-diy drivers, with this one I have a problem, „cannot be located“

sudo apt-get install librtimulib-dev?

Any idea?

Best, Helge

Hi, maybe your problem is related to port mapping, there is a tutorial called „persistent port mapping“. See Support-section on this site.

Hi Jasem,

Thanks a lot for 1 +2!

3. - I checked the guide module in Ekos, but where to select „it from the list“? I suspect intus something trivial I missed out...

4. I had another look at the log file to check the star positiom, but I may not have found the right entry. For instance „star x pos“ was different on each iteration. Or which is the relevant variable to look into. Anyway should I parametrize the backlash in the profile, e.g. from 1 to 50 for the AZ-EQ5?

5. will send a log separately

Thanks for the info on the new Raspberry Pi! The 5 GHz Wifi - will this also speedup for instance the uploading of images from the Pi to the laptop, when creating a WiFi Hotspot with the Pi?

Dear Jasem,

unfortunately, after third image capture, error message pops up (before starting polar alignment, I run the solver):

Error creating WCS file: "couldn't create the named file"

Btw: Is there a chance to safe the setting "remote" instead of "online" in the solver module?

Likewise, Internal Guider aborts after 35 iterations (RA drifting reverse).

Concerning PHD2, I observed the following: When first start "looping" in PHD2, before capturing a CCD image, the continously captured images that are displayed in the FITS viewer will cause KStars crashing upon uploading a CCD image, When first taking a CCD image, and than start PHD2 looping, PHD2 images are not anymore displayed in FITS viewer and all well.

For the focuser I encountered the following: whenever a further image is captured, the module trigger 3-4 images instantaniously, instead of just one. Still, the focuser completes succesfully, which is good.

Thanks in advance for your support!!!

Helge
