Been having issues with FilaCube PLA-2 Sticking to the bed. I finally emailed FilaCube support and they suggested to use hair spray. They also said that the nozzle might be to high or to low. I leveled the bed using my normal procedure using a piece of copy paper. Tired the hair spray and it would stick but not without heat, 40c seems to help. I normally use eSun PLA+ and it will stick to my glass bed without anything on it as long as it’s clean. I have heard good things about Hatchbox so I might give it a try.
