I don’t know if it’s a bug or just me, but when I select the preset for my X1C with E3D hotend, every print I’ve sliced has a slightly higher time to print than the standard profile. I have verified that the max volumetric flow rate is higher on the E3D profile, and I have the latest profile imported.
Are the layer times for fan speed control the same in the filament settings?
They are also used to slow down prints in case of low layer times.
