Printing is now rough

[davidnfh 0]

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?

Yes, it will be far easier to identify whats wrong if a picture is sent. 

 

I do believe from your description that it was under extrusion, but I cannot confirm it.

As madman4 has said, you may get a new nozzle but since you stated that you are a relative newbie, it is probably a clog. 

 

Try cleaning the inside of the nozzle or increase the flow rate for now. Decrease your printing speed to 35-45mm/s. Please let me know if you have any questions!

I'm surprised nobody's mentioned "bed Levelling" Have you carried our this simple process? It definitely sounds like a first contender.
