[Recommended carbon fiber filaments with UM S3?]

After testing several materials, I'm happy with Polymaker PolyMide PA6-CF with generous applied dimafix on the build plate + brim.
If also strenght between the layers is needed, especially in Z-direction, I temper at 250°C in plaster powder (instead of ground salt)
Tensile strenght at break rises to 80 N/mm². For those who are interested in details, see attached test report.

Very well done - works perfect!
I've been looking for this feature for more than a year.
Many thanks.

[PA 6 GF 30 black By Ensinger]

Hi there,
I bought a spool of PA 6 GF 30 black By Ensinger and am trying now to download/implement the material data into my cura 4.8.0
On the Ultimaker Marketplace
https://marketplace.ultimaker.com/app/cura/materials/DilaraYuece/Ensinger_PA6GF30black_2019
there is a button + add to Cura which changes to v Added to Cura (and can be toggled back) but nothing else happens.
No (visible) download happens nor can I find any new xml.fdm_material (full PC search)
Cura doesn't show any new materials entry, restart doesn't help at all.
I tried Chrome and Firefox, same behaviour. Chrome switched alredy to  v Added to Cura after log in. It somehow knew what happend in Firefox.

Am I wrong?

What does + add to Cura mean in particular?

Thanks
Sven
