@robinmdh the air manager goes 100% from the beginning.. Even when the build plate starts to warm up air manager works at 100 % which is wrong..
At least it should start at 0 % and when the build plate is hot to start working at certain percentage...
I am slicing the prints with the 4.4 Cura what do you mean by saying its a safety feature??
My question is : Does the machine ( Ultimaker S5 ) has a sensor inside the chamber for the temperature?
If not you will have real problem to tune it I think.. Just my thoughts..
