Does anybody know which mmaterial profile has the slowest feed rate ?
Comparing the contour feedrates for the 150µm ("140µm") profiles, Z-Glass seems to have the slowest feedrate, followed by Z-Hips. Z-ABS and Z-Ultrat follow next and finally Z-PCABS.
Of course the 100µm ("90µm") profiles are even slower where Z-Ultrat is slightly slower than Z-ABS at least for the contour feedrate.
There are quite a few different feedrates though for shell, contour, infill, raft etc., partly they are also differently defined depending on the layer (standard, top, etc).
