Hey Guys
I am having a similar issue, I've went on market place and downloaded 3DX Tech ASA & Formtech rPET
Both say installed on market place & in the downloads menu in Cura. but they wont sync, i've went in the top right and done a re sync, quit and re opened 2 times, even re started the PC with no luck, now i've tried a manual import of the files through their location in the configuration folders under materials.
Any tips or ideas how i can resolve this?
Kind Regards
Stefan
