I'm getting this in my log.

Hmm, try running this and give us the output.

ls -ld /home/pi/.octoprint/data/octolapse/ /home/pi/.octoprint/data/octolapse/tempsnapshots/

Looks like the plugin deletes the /home/pi/.octoprint/data/octolapse/tempsnapshots/ folder after each print
The rendered comes out fine.

5

This looks to be a permission issue. Somehow Octolapse doesn't have permission to delete/move files. Maybe run an

ls -l

command to see what the permissions are for each of those folders?

6

It saves the generated file in the timelaps folder. What I have done is to mount a network drive to the timelaps folder. Don't want all timelaps files to fill up the sd card. Works just fine the built in timelaps function.

7

That could very well be the issue. Can you share with me how you were able to do that so I can try and maybe I can recreate the issue? Never mounted a drive to a folder location before, so it should be a good learning experience for me.

Hey, how interesting that I just saw this thread: https://discourse.octoprint.org/t/use-network-storage-for-timelapse/1324

I'll try that out and see if I can figure out what the problem is.

I haven't gotten the chance to work on setting it up just yet, but considering every linux box in my house is a debian base, I can't imagine I will run into any problems (short of a network outage mid-print)

10

Aha. Yep, network drive and permissions problems go together. Are you using samba, nfs, ?

Using samba on the server (since i know how to get it working with webmin and it works relatively cleanly with windows, a few permissions on new files issues nonwithstanding from time to time) and then mount the network shares as cifs in my /etc/fstab, using a password file on the client to manage authentication

12

I'm using samba. I'll post my config.

13

I use this command in my fstab

//hostname/Multimedia/3dprinting/Timelapse /home/pi/.octoprint/timelapse cifs credentials=/home/pi/.smbcredentials,file_mode=0777,dir_mode=0777 0 0

I can save and create files from the command prompt and built in timelaps have no problem.
I tried to do the same with the temp folder of Octolaps but it started to write the temp files but after few screenshot it just stopped, at the end it said it could only take one snapshot.
