So I too suffer from the ever present Heat Creep. I can almost set a watch to it. 1 hr and roughly 20 minutes in, no more filament. I scoured the forum and found the post about the replacement fan which I did (the noctua 40mm fan) and it hasn’t changed a thing. I was going to do the 80mm fan but since I can’t print the duct, I can’t mount it. Oh the irony
So my question is: could it be the filament? I’m currently using the PolyLite PLA from Lulzbot. I don’t have any other to compare to, but wanted to ask before barfing out money just to have it not print again.
Any wisdom would be greatly appreciated.
