How they differ on the data
Prusament PP Carbon Fiber runs 25°C hotter on the nozzle (window midpoints 270°C and 245°C), and the windows do not overlap, so each needs its own profile. Prusament PP Glass Fiber runs 10°C hotter on the bed (window midpoints 85°C and 95°C), and the two windows share 10°C of range, so one profile can cover both.
