EDIT: I found a solution.
Does anyone use alexe's firmware on a Voxelab Aquila? I have trouble getting the preview images to show up on my printer. I changed from cura to orca (just better), the only issue I have is, that the previews fail to show up on the printer's display.

I don't know that fw but if it's Marlin based, it will likely not work. Only Cura is generating working previews AFAIK

#

I've never got it working with Orca at least

Yeah, it's marlin based. I'll have a look around for a post processing solution. Maybe I can find something there.

in case anyone is interested. I found a python post production script that almost works for Marlin thumbnails and fixed it to work properly with orca.
original repo (with instructions): https://github.com/mriscoc/Ender3V2S1/wiki/How-to-generate-a-gcode-preview
and the reviewed code

📎 orca_marlin_thumbnail.py

Remember, this is not my code, I merely added a little "jpeg" in the appropriate spot 😛
