Has anyone looked at either Bambu or Orca Slicer both now support some 3rd party printers. I downloaded the Linux appimage and setup my Ender 3 S1 Pro as a Ender 3 v2 and changed the build height to 270 just used generic plastic to give it a try. I sliced a crate at 0.20mm using the stock setting and it will take 9h39m to print. Sliced the same file in PrusaSlicer and using 0.20mm layer height sliced the print time was 10h48m. Can’t say what they quality difference will be as it’s still printing but the 1st layers are looking good. Can’t say for sure how it cut an hour off the print time.
Bambu Slicer is a fork of PrusaSlicer but they changed the UI quite a bit. I don’t think it will import Prusa configs because all the Bambu Slicer config files are .json and Prusa uses .ini
Orca Slicer is just a fork of Bambu Slicer much as Supper Slicer is a fork of Prusa Slicer. On the Bambu Labs Wiki there is an article on adding 3rd party printers with an example.
If you’re using PrusaSlicer I don’t think the learning curve will be that bad, just getting use to where Bambu put stuff. It also has some features that PS doesn’t have such as multiple build plates.
