Apologies if this has been asked already - I am a relative newbie. I was trying to print facemark holders for the NHS, but they fall apart. With Ender3 Pro and Cura 4.2.1 with PLA my first prints were beautiful. Recently they have become rough and the layers don't seem to be sticking well (easy to break). I am drowning in all the options. Have tried Super Quality and 60% infill but may have some other settings wrong, though I don't think I had changed them. No idea if it is Cura or Ender problem (plate is level). Suggestions?
