eSUN PLA printing fine over the last week, and this morning, but this afternoon prints just stopped sticking (they are sticking about 80%) and the head seems to get messy as a result. I believe both the head and the bed look to be the right temperature.
I’m sure there are many possible causes:
Screws on head loose?
Clamp for filament set to wrong pressure?
I’m not sure what’s going on. I’m too inexperienced. I keep the head as clean as I can and have the printer set to default settings. And like I say, PLA printed fine for me up until this point. I have the machine just over a week.
