jneilliii / octoprint-prusaslicerthumbnails Goto Github PK

I installed PrusaSlicer Thumbnails 0.0.7 with Octoprint 1.4.0 and Python 3.6.9, but unfortunately, there's no new image button. I double checked, this gcode does have the thumbnail comments at the first few lines. I did not spot any errors on octoprint.log as well.

I started using the 2.3.0 beta version of PrusaSlicer and lost my nice thumbnails.

Hi Thanks for your hard work,i love your Plugin,in the new PrusaSlicer 2.3 Alpha 2 your Plugin dont works,can you please make a new workaround for thumbnails = 16x16,220x124 because in PrusaSlicer 2.3 the Octoprinter Profil is a Pysical Printer Profil and there is no line with thumbnails ? Thanks

Select Show Configuration Folder from the help menu a directory should open that is on your machine. In that folder there is a sub-folder named printers. Each of the ini files in that folder are the equivalent of your Printer list you see in PrusaSlicer in the top right of the application. Open the printer setting you want to modify in a text editor like Notepad or Notepad++ (all depends on your operating system) and look for the text "thumbnails = " and add the resolutions after the equal sign. So for example make it so it looks like "thumbnails = 16x16,220,124" (without the quotes). Once you've made the change restart PrusaSlicer and slice up a file and upload to OctoPrint.

The instructions for other printers (including my MK3s) indicate I should adjust an entry called thumbnail. This entry was not there in my configuration file, there is a entry thumbnails however.
Adjusting that as indicated worked just fine :)

Had an existing subdir in OctoPrint file structure hosting some old files and when I navigate into this directory none of the line items (separate gcode files) have the icon for the thumbnail. But works GREAT in main directory.

I am using a DeleteAfterPrint Plugin. When I move file from archive folder back to root thumbnail is gone.
When moved back to archive thumbnail is back.

For me current regex is too greedy.
When slicer generates small and big thumbnail in octoprint I see only the small one(first instead of last).
After a little of debugging I saw that len(matches) returns 1. Problem is that current regex match from start of first thumbnail to the end of second one.
Changing
regex = r"(?:^; thumbnail begin \d+x\d+ \d+)(?:\n|\r\n?)((?:.+(?:\n|\r\n?))+)(?:^; thumbnail end)"
to
regex = r"(?:^; thumbnail begin \d+x\d+ \d+)(?:\n|\r\n?)((?:.+(?:\n|\r\n?))+?)(?:^; thumbnail end)"
Fixes problem for me and shouldn't break anything.

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. :)

I have 5 printers running off one server with 5 octoprint instances. They share an upload folder but the g-code is only sent to one instance's API key.

when I upload, the printer with the API key loads the thumbnail no issues but all other instances show a small place holder photo.

Since updating to 0.1.0 there is no tumb in State Panel.

Settings:

Image is shown in files panel... :(

I stopped seeing thumbnails at some point, and I see this in OctoPrint's log on a freshly-uploaded file:

This may be related to #40 and #34?

First thanks for the plugin, it is a huge help keeping track of items in the queue.

I have inline thumbnails enabled and when I mouse over the image, the entire file "cell" including details and action buttons highlights implying some sort of global action, but a click only brings up an enlarged version of the image itself. It would be extremely convenient if this window included action buttons (posibly a large print button) and all of the extended file details as part of a purpose made screen. A small extension would be arrow buttons (and or Up/down keyboard shortcuts) to scroll through all files while in this popout window with the larger image size to clearly see differences in files.

With inline thumbnails displayed, only one file fits in the Files pane at a time and then only with careful alignment and the extended details hidden, breaking everything out to a larger window makes reading this easier. An option (probably a separate feature request) to extend the height of the Files panel would also be a useful adaptaiton to better show off the thumbnails.

Hello,
First of all thanks for very usefull plugin. Great work. I really appretiate it.

I cannot see the image icon to preview the thumbnail. Thumbnails are being shown all the time.

Running: OctoPrint 1.3.12 running on OctoPi 0.16.0, PrusaSlicerThumbnails 0.0.4
 

Hi. I'm having an issue with the Thumbnail feature not working correctly in Octoprint. This may well be a mistake on my part.

Steps taken:
1.) Go to Help > Show Configuration Folder
2.) Go to vendor folder and open PrusaResearch.ini
3.) Add in a thumbnails line..exact code including last line of thumbnails is:

[printer_model:MK3S]
name = Original Prusa i3 MK3S
variants = 0.4; 0.25; 0.6
technology = FFF
family = MK3
bed_model = mk3_bed.stl
bed_texture = mk3.svg
default_materials = Generic PLA; Generic ABS; Generic PETG; Prusament PLA; Prusament PETG; Prusament ASA; Prusament PC Blend
thumbnails = 16x16,220x124

4.) In PrusaSlicer..import a model...Slice model...press 'send to printer'

5.) Model appears in Octoprint..but no thumbnail icon appears.

Thanks for any clues on what I'm doing wrong...(unless this is a bug..but seems unlikely given others have no issuess)

Would it be possible for alignment options to be a dropdown menu or radio buttons etc.? At the moment you have to type in what you want.

Fixed options will negate issues with folk who don't understand html/css commands...and anyone who doesn't use US English spelling for 'centre'!

No immediate hurry, but just a suggestion to avoid confusion/error.

Many thanks.

Hello,
Sorry I don't understand what I must to do in Themeify with this line:
div.row-fluid.inline_prusa_thumbnail > img
Can you explain me?

Unfortunately, when I create a copy of the profile (for the MK3S) and add the thumbnail line to it, Prusaslicer crashes when I try to load the new printer profile. I'm using PS 2.1.1 64bit and edited the ini file with notepad++. I've uploaded the resulting ini file in case anyone wants to take a look and provide any suggestions.

Original Prusa i3 MK3S - Smith.zip

I'm running OctoPrint 1.4.0 (@ OctoPi 0.16.0).

Installing PrusaSlicer Thumbnails 0.1.0 doesn't show up the button for displaying the thumbnail:

As additional info: I'm running the Canvas Plugin 2.3.3 since I have the Palette2. This plugin also modified the UI, by adding additional information to the file list.

Best regards,
Bastian

Messing around with changing the order of the thumbnails in the gcode and notice that it appears once you have a thumbnail for an object, a new one isn't created when the same filename is re-uploaded.

Other than that seems to be working as expected.

I can't put my hands on the Mini at the moment as it's remote, but my recollection is that the 16x16 thumbnail is used in the object list on the display, and the larger thumbnail is used when viewing or printing the object. I'm not sure if they parse that out, or if they just take the first thumbnail and use it for the object list. Changing the order in the ini does of course change the order in the gcode, but might not work on the Mini, I'll have to test that when I can physically get to the Mini.

As I'm updating my plugins in OctoPrint I'm noticing your name on a majority of the plugins I use, is there some place I can drop you a tip? Same username on Thingiverse, I could use that?

First, I'm not even sure if, as part of the OctoPrint plugin system, you can even expose something via the REST API to begin with... that being said.

It would be awesome if there were a REST endpoint where I could fetch the thumbnail image of the current print.

Or maybe offer it up as an endpoint with a secure token on the end, like:

http://192.168.0.2/api/plugins/thumbnails/currentjob.jpg?token=abcd1234abcd1234....

I was hoping that it would be available in the GET /api/job call but no dice there.

Is this possible, and if so, could this be added in a future update?

Hi there,

I'm running octoprint in 2 instances on one RPi.
http://192.168.73.245/P2
http://192.168.73.245/P1
defined in haproxy config
haproxy.zip

But this plugin generates image url
http://192.168.73.245/plugin/prusaslicerthumbnails/thumbnail/Shape-Box_0.6n_0.1mm_PETG.png?20200422110821
As you can see, the part which defines which Octoprint instance is called (/P1 or /P2) is missing in your image url.

Please, can you repair it?

There's a chance that previously uploaded gcode with successfully extracted images will not display the button or inline thumbnail after upgrading to 0.0.5. This is a result of the compatibility feature with UltimakerFormatPackage and was required to allow both plugins to work together. Simply re-uploading your gcode files should resolve the problem.

I use this version of PrusaSlicer (in the title) and it denies to start after i add the thumbnail sizes in the printer configuration.
Is this a problem with the slicer version?
Which version is safe?

With MK3 printers the thumbnail included in the gcode when uploaded to SD card causes a delay when you start the print as it processes through the comments. See prusa3d/PrusaSlicer#4127

trying out the latest alpha version 2.3.0 but not able to get the thumbnails working.
Any idea where to add the settings? Tried already all printer inis without success :-(

thumbnails = 16x16,220x124

It would be nice to be able to trigger a scan via API from an external program/script.

I often copy gcode files between printers via script and have to go to settings and rescan after each.

Is it possible to also add thumbnail here?

am using the gcode editor plugin which inserts an icon next to the "open" and "print" icons below the gcode file in the file manager. The thumbnail will not display because of this. Once disabled the thumbnail displays fine. Inline, and with button.

Hi! I'm running multiple instances of Octoprint on the same system to be able to control two printers from the same RPi. I followed this guide and all works well. However, for some reason I only see the thumbnail pictures on one of the instances (the one I uploaded the gcode to), So if I upload to my "MK2.5", I only see the thumb there, and a "broken" thumb in the "MK3" instance. I'm using the "same" upload directory on both instances (located on another server). Even though I do a "Scan files", the thumbnail does not show in the "other" instance... Here is a picture example...

I don't know if this is fixable. Maybe if the "thumbnail-storage-directory" could be set manually in a configuration option?
The first instance uses : ~/.octoprint/data/prusaslicerthumbnails/
and the second uses: ~/.octoprint2/data/prusaslicerthumbnails/
And that's ok, but the thumbs only get's "created" on upload... ?

The thumbnail displayed in the State panel does not update if a gcode file of the same name is uploaded. The new gcode will be printed if the State panel's print button is pressed, but the State panel thumbnail will remain out of date.

Steps to reproduce:

1. Upload a gcode file
2. Start a print
3. Cancel the print
4. Upload a different gcode file under the same name
5. Notice the difference between the thumbnails in the State panel and the Files panel.

An example is shown here, where a model was cut, the new STL sliced, and the resulting gcode uploaded under the same name:

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

I uploaded big (128MB) .gcode file, and no picture is shown in Octoprint.

Hi,

is there a way to change the Thumbnail color (Brown) to another color ? Or is this question related to Prusa Slicer ?

Hi with the last version 0.0.4 if I send a job to Octoprint all lock. And the Octoprint take 100CPU.
Disable the plugin or use the previus version (0.0.3) all work great.

No specific log found.
You can download an example of the gcode from url Gcode File. Link valid until 1/5/2020

After the most recent update my thumbnails are intermittently working.

Im having the same issue. After updating to 0.1.1 - newly sliced gcodes dont show a thumbnail.
The gcode file still contains "; thumbnail begin 16x16 832".

Now to the strange part:
Im running multiple instances of OP on one Pi. On the first printer (Prusa) it doesnt show the thumbnail, but on the second printer (Anycubic) it does. I sliced them with different printer profiles (both have thumbs enabled).

If i upload the "Anycubic gcode" to the Prusa - the thumb is showing.
Maybe this helps finding the issue.

So I installed the plugin manually (not available through the plugin manager), everything went fine, I have the configuration options in the settings.

I also modified my printer configuration file as described in the settings and export a GCODE with prusaslicer. But no image icon is showing up in the list... I tried enabling the preview option but that does not change a thing either.

The plugin seems to be loaded in my OctoPrint 1.4.0 instance The plugin configuration page does show up in the OctoPrint settings.

However, I don't get the new button showing up in the file list as expected.

I have a GCode file with the thumbnail embedded in the file list, but I would think the button would show up regardless of what was in the file.

Any idea what I might be missing?

All was working with 0.0.2 but with the 0.0.3 update no more webcam streaming.

With 0.0.3 stopped, my webcam streaming is back.

I have the Spaguetti Detective plugin

I'm using two octoprint instances, one for a Prusa Mini and one for an MK3S, the Mini works fine and displays the thumbnail in the State and in the Files inline, the MK3S only shows the thumbnail inline in the Files and not the State.

I've made the modification to the printer ini in Slic3r PE, have the newest version of Slicer, newest version of Octoprint with Python3, newest version of the Thumbnail Plugin and have rebooted the OctoPi and flagged and reflagged the setting, the gcode has the thumbnail in it and it is showing up in the file but I can not get it to show in the Printer State.

Any ideas?

After installing the latest version, the show thumbnail button doesn't appear after uploading a new gcode file. If one hits the scan files button, the button subsequently appears.

when i click on the hompage button where i can download your plugin it leads to this page

https://github.com/scottrini/OctoPrint-PrusaLevelingGuide

Tiny bug I think:
The preview icon is not available when choosing 'Start printing after upload' in PrusaSlicer.
It only shows up when you do not print it immediately, or when the print is finished.

For the rest, 👍🏻💪🏻
Great job.

Updated two separate Octoprint Pi machines, a MK3s and a Prusa Mini to Octoprint 1.5.0
After the update both machines no longer show thumbnails in State, but does show thumbnails in Files.
I disabled all my installed plugins for my Prusa Mini to see if any of them were interfering with your plug-in but still no thumbnails in the State window.

I've been trying since vesion 0.4 to 1.0 never had any change in the interface or button.

I've reinstalled and erased all data, including my print files.

After trying to manipulate the different view options i am unable to get the files to print from my touch UI instance. Only the website works. which is very inconvenient, and breaks my workflow.

This is a very important feature and it renders the use of touch ui semi useless as a standalone controller.

Images below reflect inline and stateless views. Paul de Vries (BillyBlaze) Might have to alter Touch UI to work with this plugin.

I noticed that the thumbnail of the current print was disappearing after a while, and I realized that it was either because I was reloading the page, or because I was looking from another browser.

If the user choose to have the thumbnail in "State" panel while printing and the gcode is located in a folder, the thumbnail disappears when user navigate out of that folder or to another folder
in this example I'm printing a file from "Speaker_Box" folder and when I'm viewing the root folder there is no thumbnail:



but if I navigate to the mentioned folder it appears:
