ArcWelderLib VS Prusa-MK3-Material-Profiles

definitely arc welder, but you have to have g1 g2 enabled on your firmware. read this command here here and you can download the console app to run it on your exported gcode on arcwelders github

For other slicers, you will need to use a script like ArcWelder (Cura Plugin) (Script for other slicers)

Look into Arc Welder for further explanation and as a potential solution (though it is not perfect and can have its own downsides). The OctoPrint plugin is no longer maintained afaik, but there is a Cura plugin and other slicer post-processing methods.

You could also post process your sliced model through ArcWelder and get perfect arc curves for your print. It will go through the G-codes, detect curves, and change them to G2/G3 arc codes removing the edges completely.

if you're feeling really adventurous you could manually apply arcwelder using CLI https://github.com/FormerLurker/ArcWelderLib

The only way to improve the bridging performance is to use a very conservative amount of cooling fan, I'm talking max 15%. I have a number of print profiles hosted on my GitHub page, including the files I used for PolyMax PC. You should also be printing pretty slowly, a max of maybe 40 mm/s.
