Thumbnail/Gcode Preview for Slic3r/PrusaSlicer/SuperSlicer for BigTreeTech TFT Screens

[sarvenn]

Hi,
Thumbnails generated by Slicer could not be viewed in BTT screens. Codes generated by slicer is not applicable for BTT TFT screens.

In BTT touch screen repository there is a custom solution for that. Please see the link below.
Could this solution be integrated to SuperSlicer?

I almost understand what the format is.

But can you link here a gcode file from SuperSlicer (or PS) with & without the script?

Here you go, a calibration cube sliced with superslicer (by the way thanks for superslicer, it's awesome), with (_btt.g file) and without the script.
xyzCalibration_cube.zip

I also plan to try superslicer. I started Cura since last year, then switched to PS a month ago. Actually Cura had more features but PS seems to be more fast (program itself and printing times). I would like to try SuperSlicer as well. I wish SS will integrate a solution for BTT TFT screen compatible gcode preview.

@supermerill hi. Btt tft fw is now compatible with prusaslicer's thumbnail generation aporoach.

[effgarces]

True, but not all of the TFT's support it, due to memory issues, so there's value in having this feature.

Great to hear that. Thnx.

[sarvenn]

Somehow I closed this issue, I don't know how but it's better to have a look again here @supermerill .
If you find it's too hard to integrate this solution to SS, I can close the issue upon your request.

[sarvenn]

I know that PS developers are not interested in.

[supermerill]

I just merge the JPG / QOI thumbnail from prusa, adding that one.

[supermerill]

Can someone test if you can see a yellow cube on white background?
Just copy-paste this on the start of a gcode file:
