Cura not cooling on first layer over infill and support

Recommended Posts

Posted · Cura not cooling on first layer over infill and support



I am currently migrating from slic3r PE to Cura but I am unable to solve the problem that the layer directly after the infill of is printed with the fan speed that applies to the minimum layer time and regular fan speed.

The same happens for layers printing on support.


Since I am printing petg with only 20% regular fan speed and only 10% infill the printed filament sags through the infill gaps leaving holes and crumbles.


Slic3r threats these layers as bridges so cooling is more efficient here.

Can someone point me into the right direction how to solve this?
