Hi,  
I am currently trying to print dual extrusion with two different materials (ABS, PLA Breakaway Support). Since ABS is printed with fan off and pla needs fan on, i was expecting that Luban is capable of doing so. But the problem is, that during the print, the fanspeed is always at 100% for both extruders. This causes the print to fail.  
Is there any solution?

In the material selection, you will find the fan setting for each material, which can be set separately for each material.

Yes, but it was not working. But I think I found the issue. When changing it back to 0% and change it again to 100% and vice versa for the other material, it worked.  
So it looks, like the setting was not saved somehow.

Thank you
