Cura thumbnails are not shown

tapirath

Hi all,

Here is a snippet from the latest Cura. Looks like the format seems fine and indeed the image format used is PNG, so I'm not sure why DWC can't view them.

Any ideas?

@tapirath are you running RRF and DWC 3.4? Also DSF 3.4 if using SBC.

Cura 4.13.1 works fine with @resam plugin.
The duet plugin currently doesn't work with cura 5 beta so the thumbnails may not work correctly until the plugin works again

@dc42

I'm running 3.4 stable both RRF and DWC. Standalone mode.
The thumbnail is created with the official post-processing plugin of cura.

@jay_s_uk I'm not sure it has anything to do with Cura version. It's the exact same post-processing script.

Here is the link to the script: https://github.com/Ultimaker/Cura/blob/master/plugins/PostProcessingPlugin/scripts/CreateThumbnail.py

You can switch between master and 5.0 branch. It looks same to me.

Cura-DuetRRF Plugin for Cura V5 is already submitted for review by the Ultimaker Marketplace team - usually takes a few days before the approve and its available. Until then, you can use the manual installation method from the next branch of the plugin - and download the zip file also from the next branch: https://github.com/Kriechi/Cura-DuetRRFPlugin/tree/next#manual-installation

Maybe I'm missing an information here but my problem has no relevance to the Cura RRF plugin. I don't use that plugin. This is a post-processing script that embeds the thumbnail in the gcode and I upload the gcode manually via DWC.

@tapirath I didn't specifically comment about your case - just general information.

But regarding your case: the post-processing script is not generating valid thumbnail comments:

the width and height need to be separated by an x, not a space character. At least that's what the plugin is doing - and its working there.

tapirath

@dc42 would you be willing to fix it on your end or should report to Cura?

resam

@tapirath thats a Cura problem - so please report it to them. I'm not even sure if they built this specifically to be compatible with Duet / RepRapFirmware.

Yes, RRF expects a 'x' between the width and height (which is what PrusaSlicer generates), not a space. Best get it fixed in Cura because it may not only affect RRF.
