Between each layer, the print head moves out of the way and manually presses a remote trigger on my DSLR creating a really nice, high quality time lapse.
I have created a relay system that can use a Wemos D1 Mini to control two relays that a) focus and b) take the shot just like I was pressing the buttons myself.
If I were able to monitor layer completion, and/or a specific position of the print-head then HA could use that as the trigger to fire the camera.
It doesn’t look like the integration does much more than just monitor temperature and job status…is that true?
