How to get thumbnails on Paneldue ?

As in the title .
How to get the gcode thumbnail display when printing on Paneldue ?
Paneldue software version 3.4.1
Duet 2 Wifi beta version v3.5 2.
PrusaSlicer 2.5.1 in settings : Reprapfirmware , QOI, 120x120.
Cura with plugin : Cura-DuetRRFPlugin.
In DWC thumbnails generate correctly but on Paneldue nothing.
What am I doing wrong ?

Which hardware version of PanelDue is it?

There have been a few pre-releases of PanelDue firmware, might be worth downloading and reflashing again.

@g-biel the thumbnail should be displayed when you select a file for printing that contains a QOI image. It may take a few seconds to load. You can increase the baud rate to 115200 and set the error checking to CRC to speed this up. When you press OK to print the file, the file popup window containing the image is removed, so the image is no longer displayed.

Yes .
I know How and when the thumbnails should be displayed . But with me it does not show them.
Tomorrow as suggested by @Phaedrux I will upload paneldue firmware again .

@g-biel you can check which version of PanelDueFirmware is installed on the Setup page. I am running 3.4.1 and it is working for me.

You can also open the GCode file in the DWC editor to check that it contains a QOI thumbnail. It should look something like this:

; generated by PrusaSlicer 2.5.0-alpha0+n8 on 2022-12-26 at 16:02:24 UTC

; thumbnail_QOI begin 160x160 25180

I'm seeing a similar issue, I do see icons for some things, but it is hit or miss. As an example I have two gcode files, both recently generated by Cura 5.2.1, and I have the latest 3.4.1 paneldue firmware... on both files it shows the icon in the DWC web interface, but only one of the files shows an icon on the panel due. Both have the line "Generated with Cura_SteamEngine 5.2.1" at the end of the thumbnail data in the gcode, but only one of them shows "Cura SteamEngine 5.2.1" in the "generated by" column in the DWC web interface. The thumbnail data in both looks correct to my eye, nothing looks out of sorts in either one. I don't see any correlation between files that properly show "generated in Cura" and files that do or don't show an icon on the paneldue. Seems like there is a subtle bug in the metadata creation and/or parsing.

I have the latest RRF cura plugin installed.

@skrotz @g-biel if you are unable to resolve this, please share the GCode files that you think should display in PanelDue but don't.

@Phaedrux , @dc42

So there is progress .
After the third installation of paneldue software finally I have thumbnails .
But the strange thing is that I had to install the version with the logo , and only appeared thumbnails later after returning to the software without the logo that was originally still there . From my point of view , flash cleaning does not work or causes problems and some garbage remains. I once had a similar problem with ESP8266 and had to upload Blank.bin to erase the flash.

And now the question is do you have plans to add a thumbnail display on the Status panel when printing?
