No parts visible in the jlcpcb part placement preview with the generated files.

Describe the bug The generated files don’t seem to be understood by the jlcpcb review parts placement preview thingey. I tried using this plugin with my own design first, and, even though there are “selected parts”, none of them are showing up in the preview. I heard that the kicad coordinate system is a little different than most. For this reason I tried creating a pcb of 30x30cm with the center at the 0,0 coordinate and a bunch of parts spread out over this pcb. But even this pcb didn’t have any parts on it (it is not that they weren’t in the right place. They just aren’t there). I tried creating some test files with easyeda, and those seem to work just fine, so it is not my browser or something like that.

This is what it looks like:

To Reproduce Use the plugin to create the following files: GERBER-JLC pca test.zip BOM-JLC pca test.csv POS-JLC pca test.csv Go through the jlcpcb ordering process, and see no parts in the preview.

Just as an information on this matter: The preview and orientation of the parts is completely irrelevant for JLC to manufacture your board. They say that engeneers will take a look at your data before manufactureig anyway … And to be honst, their preview sucks, in my eyes not out of alpha stage at this point …

I’ll look into this soon
