Can't upload gcode with thumbnails.

[drewsed]

Hi,

thanks for this great plugin.
I am using
PrusaSlicer Version 2.2.0+w64 and
Octoprint Version 1.4.0

I created a new Printer Profile in PrusaSlicer, that the thumbnails = section appears.
Then I sliced a stl file and uploaded it to Octoprint. It is working fine through PrusaSlicer and drag&drop on the webUI.

Then i added thumbnails = 16x16,220x124 and from that moment on, the upload to Octoprint fails with the following error:

Konnte die Datei nicht hochladen. Bitte stelle sicher, dass es sich um eine lesbare valide Datei mit einer dieser Erweiterungen ist: .g, .gco, .gcode

If I change the thumbnails = 16x16,220x124 back to thumbnails = the upload is working again.
So, I don't think this is an issue of your plugin, but maybe Octoprint or my configuation.
Any help is appreciated.

Thanks,
Andi

Same error for me. Cannot upload gcode that has been generated with printer profiles modified as per your instructions.

As soon as I revert back to my previous printer profile, the exact same gcode (minus thumbnails) uploads fine.

PrusaSlicer Version 2.2.0+w64 and
Octoprint Version 1.4.0

Strange. I do not have the problem. And like you ruralaccent i have the Dashboard plugin.

[drewsed]

Strange. I do not have the problem. And like you ruralaccent i have the Dashboard plugin.

Good point: For me I have only this thumbnail plugin installed.

[jmarc67]

I have also this plugin: "Upload anything" https://plugins.octoprint.org/plugins/uploadanything/
you could try it perhaps it would help you.

[ruralaccent]

Hmmm. I had to disable and remove upload anything as it was conflicting with something else and preventing me from being able to print uploaded files. I will try it again, but unless something has changed, then I don't think it'll be a solution for me. If it's down to default Octoprint behaviour blocking upload, then think this thumbnail plugin should include the code to be able to upload gcode with thumbnails and not rely on the functionality of another plugins (which is a weakness of the dashboard plugin, for example).

[ruralaccent]

I have also this plugin: "Upload anything" https://plugins.octoprint.org/plugins/uploadanything/
you could try it perhaps it would help you.

Just to confirm, I have loaded the Upload Anything plugin and I still cannot upload gcode files with a thumbnail included, made by Prusa Slicer.

[drewsed]

I installed "Upload Anything" and can upload files via webUI and also the thumbnail is shown correctly, but i cannot upload directly from PrusaSlicer. So this isn't an option for me either.

[jmarc67]

Ah ok. i didnot try to upload directly from prusaSlicer. Just uploaded files via webUI.
I'll try.

Update: Direct upload is working fine for me.

[jneilliii]

Anyone getting an upload error like that needs to include their octoprint.log as it will include more detailed errors for me to find a solution.

[ruralaccent]

Here are my logs relevant to the upload error...

Just to confirm, my issue is the opposite to drewsed, because I can upload thumbnail gcode directly from Prusa Slicer, but cannot upload via webUI.

Weird, what did you try first? I first uploaded from PrusaSlicer and got an error, then I checked uploading via webUI and saw that error you postet as screenshot.

Edit: Do you see the thumbnail after Upload? PrusaSlicer has to be restarted in order to reload the printer profiles you edited. Maybe there is still no thumbnail included?

Strangley, whilst I can still upload via Prusa Slicer, the thumbnails are no longer showing in Octoprint UI...

I move the files from root to a different directory. Thumbnail was fine at first, but then I restarted the server and now I don't see the thumbnail, just a placeholder.

Edit: I did restart Prusa Slicer, so that's not the issue. :)

Can you also share your example gcode files? There's nothing in those logs that give me the detailed errors I was expecting to see.

[drewsed]

thumbnail.gcode.txt
no_thumbnail.gcode.txt

I just realized, that during a print it is possible to upload files both, via PrusaSlicer and webUI. But at this moment the icon does not show up, maybe because its disabled during print:

In about 7h I will see if the thumbs are shown...

[ruralaccent]

What other plugins do you guys have installed? Moving files could break thumbnails.

I have lots of files and dirs on octoprint, so have to be able to move files. However, it did work fine at first.

[jneilliii]

But at this moment the icon does not show up, maybe because its disabled during print:

The thumbnail url gets injected into the metadata upon File Analysis completion (print time estimates, etc.) and becomes available at the same time the "Additional Details" button(drop-down arrow) becomes enabled. This analysis is paused while printing, so the button/inline image will show after your print finishes I hope.

[jneilliii]

@drewsed looks like your thumbnail gcode works fine. I assume this is related to your multiple instances or because you have an ongoing print.

[drewsed]

Well, everything i wrote here was before starting my print.
I can upload a thumbnail.gcode file with plugin "Upload anything" installed, and then the thumbnail was shown fine. But i cannot upload a thumbnail.gcode file from Prusaslicer, so i removed "Upload anything" plugin.

And now after starting my print, i can upload via PS and webUI (without "Upload anything" plugin), maybe because some checks are disabled during a print as you mentioned.
So i think this issue is on Octoprints side because of security checks on the files. I wonder why Prusa Mini users do not complain about this issue all over the internet, when the thumbnail is enabled by default in this printer profile.

@drewsed looks like your thumbnail gcode works fine. I assume this is related to your multiple instances or because you have an ongoing print.

I do not have multi instances, i just run my webUI on port 5000 rather than 80. But it does not seem to be a problem, because i already have seen a thumbnail once i got a file uploaded.

[jneilliii]

I do not have multi instances,

Sorry, I misinterpreted your post on the other issue. Thought you had that as well. Yeah, port number shouldn't effect this at all. I guess the next question is are you uploading to Local Storage or SD card?

[drewsed]

Sorry

No problem, glad you clarified :). I'm uploadig to Local Storage.

[ruralaccent]

I've narrowed it down more on my installation. I can upload fine with a thumbnail to the local root dir (via PS and UI), but it fails whenever I try to upload to a subdir. Fails if I used UI and Prusa Slicer upload.

[CYberiusPT]

Hello..

Thanks for this plugin :)

I am having issues as well..

I made the changes in Prusaslicer as mencioned and confirmed the gcode has now the thumbnail code.

Installed the plugin and restarted the service..
I have multiple folders with a few gcodes files of previous prints...
It doesn't show the thumbnail icon as the above.. at first i was thinking that it's because none of that files has the actual thumbnail code as they made before...

After that, unable to upload any file (web or PS). The error was the same as the above...

I deactivated the plugin and it's now the uploading is working fine even with the thumbnail gcode generated..

Activated again, rebooted and the thumbnail icon is still not showing...

The Displaylayerprogress plugin make changes to the gcode during upload... Maybe is something to do with this?

Not really know what info to give for helping to solve this issue..

Thanks!

EDIT: I too always upload to a subdir... didn't test to root... but the thumbnail icon is not showing still..

[jneilliii]

Are all you guys having this problem uploading to a sub-folder? That may have something to do with it. Also, DisplayLayerProgress may interfere, does the same thing happen with that plugin disabled? Also the thumbnail will not show until after file analysis, so if you use the option to start the print automatically it will not show the button/inline image right away.

[ruralaccent]

I disabled displaylayerprogress last week for another reason, so defo not that with me.

Edit: I also managed to move one gcode file to a sub dir and thumb ok, but any others that are moved loose the thumbnail.

[jneilliii]

One last question for now, have to get back to my day job...lol. If you restart OctoPrint are there any errors in the log shown during the initial startup of the application?

[drewsed]

I have no errors in the whole log except those upload errors i posted above.

Edit: My setup is also still running in a virtualenv version of Python 2.7, because it is recommended due to plugin compatibility...

@ruralaccent is you disable PrintTimeGenius Plugin does the issue remain?

[ruralaccent]

@ruralaccent is you disable PrintTimeGenius Plugin does the issue remain?

Just tried it. Makes no difference, unfortunately.

[jneilliii]

I have successfully re-created the same error by trying to upload to a sub-folder, so at least that might be related to your problem @ruralaccent and @drewsed I will look into why that is happening and get it resolved as soon as possible.

[jneilliii]

Alright, I think I have the issue fixed, at least with my testing. If you guys don't mind trying, install an updated version by using the URL below in plugin manager and give it a go.

https://github.com/jneilliii/OctoPrint-PrusaSlicerThumbnails/archive/0.0.3.zip

[safusu]

Just tested v0.0.3, not getting the 500 internal server error anymore

[ruralaccent]

Yes. v0.0.3 seems to work for me know. Many thanks :)

[jneilliii]

Thanks @safusu, is the thumbnail showing or are you currently printing and the thumbnail url hasn't been updated yet due to file analysis not being completed?

[safusu]

Thanks @safusu, is the thumbnail showing or are you currently printing and the thumbnail url hasn't been updated yet due to file analysis not being completed?

Thumbnail shows properly

[jneilliii]

Great, I just officially released an update with these changes. You guys don't need to do anything that have already manually updated.

[ruralaccent]

Thanks for this great plugin and for fixing it so quickly :)

[drewsed]

Yes, thanks so much. I think it's not a surprise anymore, now it is working for me fine, too.

Great :-*
