I have a Printrbot Simple Metal, and at the time I got it, I was using Cura 15.04 (I believe). Well, a year later and a hard drive crash and I am back to using the printer. I installed Cura 3.0, which seems to be quite a bit better than the old 15.xx version, but there's a setting I can't find.
I use to be able to set the cooling fan to come on only after a certain number of layers were printed, now all I see is "Cooling: On / Off". Is there still a way to set when the fan starts cooling?
