CuraEngine Fan Speed Trouble
I do not understand the fan speed control in CuraEngine. Is this a bug?
In the "Filament" tab I have set the minimum fan speed to 10% and the max 30%.
In the "Extrusion" tab I set "fan max at height" to 3mm.
Cooling is enabled on the slicing tab. I am slicing using the correct profile with these settings.
However, when I slice with Cura, the resulting gcode does not scale the fan speed correctly at the layers. By the time my Z-axis reaches 7.5mm high the fan is only at 9%, too low to even start spinning. At layer 2, the fan was set to 1%, far below the minimum of 10%.
Why is Cura not recognizing the minimum fans speed setting and not correctly ramping the fan speed linearly as it should?
