Cura Not Loading

[helfrichmichael]

There's still a good opportunity for me here given that I have a cache pool, but that's not a requirement for unraid.

I'll adjust the unraid templates to use /mnt/user/ instead of /mnt/cache/ going forward. Thanks for this! Should be pushed in just a few minutes to the unraid templates repo.

Sounds great! Looks like you already have it on your radar 👍 . Now to export my settings from my gaming pc and import them into this instance.

When using the Unraid Docker Template, the Cura application does not load.

After connection to no vnc, the screen is black. You can move the mouse and the vnc options on the left hand side of screen is there. Right clicking the desktop presents the open box menu. Clicking on Cura fails. Other options work.

Manually running AppRun displays permission denied errors /home/cura/.local.

Reviewing the log file for cura found in /tmp has permission errors inside /home/cura/.local.

I have tried other docker image tags.

Steps to reproduce:

1. Create Container
2. Navigate to no-vnc
3. Click connect

Can you go into the terminal from the right-click menu, (feel free to hop into bash from the shell) and run ls -la /home/cura/ and ls -la /home/cura/.local/ I'm curious if the permissions weren't properly set for some reason. Doing this from master on my desktop with a fresh volume I get the following permissions.

Ran from master with docker build -t cura-novnc . && docker run --detach --volume=cura-novnc-data:/home/cura/ -p 8080:8080 --name=cura-novnc cura-novnc locally.

It seems like that is an issue. Directory doesn't exist.

To confirm, when you are running this Docker container, you are binding /home/cura/ to a local volume/mount (IE --volume=cura-novnc-data:/home/cura/), correct? I just tested this on my secondary unraid server also and it worked just fine.

It's strange considering the Dockerfile will generate the homedir. I might need to look if there's something missing if that volume was mounted in your instance.

[GitCuppaJoe]

That is the issue. I was using the default mapped volume from the Unraid template that targets: '/mnt/cache/appdata/cura'.

If I change the mapping to a new share, let's say Storage... it works fine. I tried changing the volume to '/mnt/user/appdata/cura' because that is where all of my docker configurations live (they live on the unraid cache and are backed up).

What mapping are you using? You have a share called 'cura-novnc-data'? I'm trying to think about what I can do to change the mapping to the same location my other containers are running off of.

[GitCuppaJoe]

Actually, I got it worked out. For some reason, the permissions on '/mnt/user/appdata/cura' weren't set correctly. I changed the permission on that folder:

chmod -R 777 /mnt/user/appdata/cura

We're good now! Thank you very much.

[GitCuppaJoe]

@helfrichmichael it might also be beneficial to have separate mounts for storage. Right now, the container configuration is saved in my /mnt/user/appdata/cura. I have my files hosted in a share called /Storage/3D Prints/. It would be nice to have that Storage folder be mapped to the home folder, instead of the config. That way, I can leverage the mapped folder cura and have my files in that directory without having to browse the container filesystem to find my storage volume.

I don't want to store my STLs in the appdata folder. I essentially want the Home Folder to target my storage. Picky I know, but I thought I would share this with you.

[helfrichmichael]

That's actually a change I have staged locally for Prusaslicer :D, but it will be pushed to all my slicing repositories once it's in a good spot. It will add a /prints/ bookmark on the file manager and I will provide that as a bindable mount also.

[helfrichmichael]

Added /prints/ in helfrichmichael/unraid-templates@cef9b6f to all the repositories.

I also added a note for adding these fixes if you already have an existing configuration: https://github.com/helfrichmichael/cura-novnc#note-for-those-who-installed-prior-to-021322.

Hope this helps and the Docker image is being pushed from GitHub to Docker Hub as we speak with these fixes.
