Preview error! The Horror!
PrusaLink & Connect cannot preview this gcode file, generated by PrusaSlicer 2.3.3 (current I think).
Best Answer by Eric E:
I did a look-see at the file, and there is NO thumbnail in the g-code. Why I don't know. All my other jobs are my creations created in Fusion 36o, which thumbnail perfectly. This one is from a customer, an .stl exported from Alibre.
Certainly an issue with Prusa Slicer or something else upstream, and not PrusaLink/Connect.
Bug report retracted.

Works for me
Maybe you skipped the part of instructions where you need to change the slicer profile to add 400x400 thumbnail to gcode?
Works for me 2
Using PrusaSlicer 2.4.x Beta -- UI to set thumbnail sizes works.
I used 16x16,200x200 (looks OK)
No bug here, move along folks...

Missed instructions

It seems like I missed that too. Do you have a pointer to the instructions?
Try this
While still in the Print Settings tab of your new physical printer profile, scroll downto Firmware: G-Code thumbnails line and add the 400x400 setting. That was default for me - just not getting thumbnails from .stl files generated by Alibre (customer choice). .stl files from Fusion 360 (my choice) work fine.
Not figured out. Apparently more to the story. But, clearly (to me) a PrusaSlicer issue, not PrusaLink/Connect. If there is no thumb in the gcode, not much Link/Connect can do.

RE: Preview error! The Horror!
Files created for the MINI on PrusaSlicer do show up with a preview image, those for MK3 do not (I have made no changes to stock PrusaSlicer 2.3.3).
No more
Once added the fix to the physical printer profile:
It now shows the thumbnail for MK3 prints too:
RE: Preview error! The Horror!
Hi,
I'd recommend using 380x380 for now, since this is the size in the web view currently. The images will look a bit sharper than with 400x400 since they don't have to be down scaled.
