Using the great Fabrication-Toolkit plugin I don’t find a way to avoid to export on the silkscreen the references of the components.
Have you tried contacting the author on their Github site? There seems to be a Discussion area. They may not be reading this forum.
Yes, but I haven’t received any answer yet.
I don’t think that this is possible, the addon just uses the default kicad export pipeline. You can remove the references yourself though. Edit > Edit Text and Graphics Properties. Set the tickmark at reference designators and remove it from visible. Apply and done.
