I am in the process of setting up an imaging system with EQMod. A Raspberry Pi runs INDI - connected to the SynScan, an Altair GPCAM 290M and a HitecAstroDC focuser. A client computer then runs KStars/Ekos which connects via the local network to the Pi.

Everything works perfectly, until I try to use the focuser in combination with the camera. When I click the autofocus button in Ekos, the log shows "Please wait for image capture to complete" and then "Capturing image...", but nothing else. I've tried changing the exposure (all to values below 1 second) with no avail. If I click "Stop" to abort focusing, I regain control of the mount - but can no longer capture any images with the camera manually. Interestingly, clicking "expose" in the INDI control panel counts down the remaining time correctly, but then does nothing after reaching zero, when before a window would pop up in KStars with the image. Furthermore, I've also had a message about a broken TTY pipe, suggesting an issue solely with the image transfer from the Pi.

I had a look through the log files I could find on the Pi side (which runs Ubuntu 19.10) but could not see anything glaring. I am probably missing something obvious - but thanks for any advice all the same!
