I’ve read that the part cooling fan should be off for LW PLA as it could impact on the foaming expansion.
I turn it off and within a few layers it turns back on again. I have unchecked keep fan on and have also unchecked cooling for overhangs, yet it still comes back on.
It’s affecting the outer print quality if I don’t catch it quick enough. On a 2hr print I don’t want to sit and watch just to check if the fan turns on.
