When you ran into the problem, did you have diagnostic logging enabled?

Diagnostic Logging was Enabled: Yes

What were you doing when the problem occurred

Started New Print using Octolapse, using GPhoto2 connected to my Sony A6500. First two snapshots work perfectly fine. Printer stabalizes, camera snaps a pic, and then the system downloads the image.

What should have happened?

Ideally, it would have kept working correctly.

What happened instead?

Out of 190ish planned snapshots, only about 43 were succesful, taken randomly through the print. Printer would stabalize, but the camera wouldnt take the photo. After it timed out (10s), it would show the error in the octolapse tab, and continue on.

Operating System running OctoPrint and Octolapse

OS Name: Ubuntu Server Os Version: 20.04LTS

Printer model & used firmware incl. version

Printer Model: Ender3 Printer Firmware Version: Unknown. Using octoprint, and the printer runs beautifully.

If you like this project, please support my work by becoming a patron, and consider adding a 'star' to the repository. It takes a lot of time and effort to maintain the project and respond to issues. The cost of test prints, software, cameras, printer parts, etc. can quickly add up, so every bit helps.

Something Else to note as well, now that Im trying a couple other things as well;

I tried to just have it save to the camera, and I was succesfull in getting it to snap serveral photos that way, but as soon as it runs the script you outlined, it would only take one shot every time i unplugged it from the computer. Reconnect it, and it would take one photo, either by command or by the script while printing, and then not function again. No errors, just no photos.

Ah, the dreaded sony cameras + gphoto2. Yeah, there are lots of issues with them. Miraculously some ppl have gotten them to work, but not without a lot of sweat and tears. I really wish I had one of these to play with.

I recommend some google fu, looking for known issues and resolutions with gphoto2 and your camera. Gphoto2 is continually being updated, so it's possible some of these issues are fixed on a more recent version. You might want to try the install script and use the latest dev release of gphoto2 as well. Can't hurt if things aren't working now anyway.

I guess this is a bit old by now, but if this is still an issue, first update Octolapse and then try applying the same fixes as noted in #783

I also had a brief look at the logs, it looks like Octoprint has some issue killing the gphoto2 process, probably because it's running as root.
