New Ender-3 V3, Creality Print Slicer (V5.1.6.10470) and the thumbnails in the g-code dont show on the printer touch screen.
I cant find any setting in Creality Print that would prevent them from showing.
All of the sample g-code models show their respective thumbnails in the selection screen and when the model is being printed. But, not on the models that I have created.
Any information would be appreciated.
Bill,
Thanks for the information, but those settings are already set in my Creality Print slicer.
The thumbnail data exists in the g-code for both 96x96 and 300x300 but they dont show when viewing/selecting the file from the USB drive.
About a month ago my Ender 3 S1 out of nowhere stopped showing the thumbnail, time , and material for the print. Everything blank. Everything I sliced a few hours before everything was fine. I didn’t install any Creality print or printer firmware updates either. I didn’t change a single thing. I have seen other comments with the same issue. All of the slicer settings are exactly the way they are supposed to be.
After some experimental editing of the g-code (txt) file, I have figured out how to display the model image on the selection screen and also a larger image when the model is selected.
There seems to be a discrepancy between the way Creality Slicer generates the g-code file and the information that the Ender-3 is expecting to see. Here is what I have uncovered.
G-code generated by Slicer:
;thumbnail begin 96x96 xxxx (a number, dont change it)
Then, LOTS of alphanumeric characters representing the image
;thumbnail end
I changed ;thumbnail begin to ;png begin and added 0 95 160 to the end of the line. Also changed the 96 x 96 to 96 * 96
For example:
;png begin 96 * 96 4324 0 95 160
Also, have to change the ;thumbnail end to ;png end
Similar changes had to be made to the 300 x 300 section of the g-code file.
I dont know how to communicate this coding discrepancy to the Creality people that support Slicer and the firmware in the Ender-3 machine.

Form filled out with example files (working and non-working) with explanations of the problem and the resolution that I used.
Thanks for pointing me in the direction of the form.
