Displaying Thumbnails which are in a subfolder of the main gcode folder

Closed this issue · 14 comments

davisgoodman commented

I've used your code for a bit but had issues with the layer count and also with the Thumbnails. I found out that if the gcode file is in the main folder the metadata for the thumbnail is given as the relative path against the gcode file itself. So if a file in the gcodes/subfolder/myfile.gcode, the relative path of the thumbnail will be .thumbs/myfile.png but and won't display as it should be subfolder/.thumbs/myfile.png.

I did a test and changed the state of the sensor.3d_printer_object_thumbnails in the developper tool to add the subfolder in front the state and then the thumbnail displayed in the card.

Is there anyway to make sure the subfolder are included in the path of the thumbnails?

Maybe I should ask the Moonraker team

davisgoodman commented

Discussed with the moonraker team and we need to be able in the templates to add the subdirectory if it exists in front of the thumbnail's relative path. I'm not sure how to do this. Not proficient enough in jinja2 templating

NonaSuomy commented

Is the layer count correct in moonraker? As it’s just pulling data from there via json. What is determining where the gcode goes for you? The thumbnails graphic url is reported from the entity sensor.3d_printer_object_thumbnails when I look at the json nfo it already adds .thumbs/ to the front of the thumbnail for me? You can make a manual card and populate it with all the 3d printer sensor values you will see that .thumbs is there? (I only upload gcode with SuperSlicer)

Took a bit but to access three layers deep array you have to do attributes.print_stats["info"]["current_layer"]

Under Home Assistant I played with the Developer Tools -> Template:

26

I combined both values into one button for fun as I was going to do that with the other two layer buttons.

Which should then look like this:

That's great! combines both at the same time!

Did you test if this works recursively to multiple directories deep? /directory1/directory2/directory3/.thumbs/test.png etc?

NonaSuomy commented

Discussion on HA Discord petro says to use
[:-1] if you want everything before the last
everything after the first dir.split('/')[1:]
everything before the last 2.. dir.split('/')[:-2]

so...

{{ [dir.split('/')[:-1], img] | join('/') }}

to remove the remaining directory from the end.

Multi and no directory fix for thumbnails.

@NonaSuomy
So for full directory parsing whether there is one or 10 subdirectories, this code will work, but you need to change the camera sensor to the 3d_printer_object_thumbnails instead of 3d_printer_thumbnails

While configuring KlipperScreen it mentioned the same thing about getting Print_Stats_info but in order to have accurate layer position they suggest to add SET_PRINT_STATS_INFO CURRENT_LAYER={layer_num + 1} in the "After Layer Change G-Code.

The reference is here: https://klipperscreen.readthedocs.io/en/latest/Quicktips/#layer-progress

NonaSuomy commented

Try the current code it should always select the last thumbnail.
