Sorry, I mis-read the question.
I have both BS and Orca installed, but Orca is the only one I actually use to print. Lack of a PA setting in BS is one reason why.
BS is adding features, but I still prefer Orca.
The current OrcaSlicer (1.7.0-beta) includes “Merged BambuStudio 1.7.4 changes to have better support for BambuLab printers.” I don’t see any reason to use BS.
