Octolapse killing prints

Plugins Octolapse
1

Hello, I am running octoprint 1.4.2/octolapse 0.4.0.

At seemingly random spots, the printer stops responding, octoprint notices this, and then shuts down the printer. This has only started happening since I installed and have been running octolapse.

Octolapse works fine otherwise with my DSLR connected. It just kills prints at random times.

I have my two log files here, and what stands out is in the regular log, there is this string...

Any help would be greatly appreciated! Thank you!

EDIT: I found another post where the user was having what looks like a very similar issue. (https://github.com/FormerLurker/Octolapse/issues/329) The solution was to defer the image download until the end. I started to go through the process of image deferring based on the guide, added the scripts, and got to the test phase.

I get this error when I test things:
pi@octopi:~/scripts $ /home/pi/scripts/download-from-camera-and-rename.sh TODO: ADD NECESSARY PARAMETERS
Creating directory: ADD
Saving file as IMG_0129.JPG
mv: cannot stat '.jpg': No such file or directory
mv: cannot stat '.JPEG': No such file or directory
mv: cannot stat '*.jpeg': No such file or directory

How can I move forward from here?

Not to say OctoLapse is innocent but the rendering starts after the disconnect.

The disconnect is during taking a picture with the camera. This snapshot failed. Maybe there is a causation.

I have done some testing, and the problem appears to have gone away. I ran an 8 hour print last night with no stopping, and am about to finish a 4 hour print.

The problem as far as I can tell was actually the power supply for the pi. It was not delivering enough voltage, so I replaced it with one from canakit. I have not had any errors since. I will be trying a 16+ hour print to see if the problem really is fixed.
