Ultimaker Original - Top face not filling in correctly

[AdamWood 0]

Hi Community,

 

I was hoping you could help me. I'm currently trying to print some Christmas ornaments but keep getting this on the top face. Any recommendations on what I need to do. This was a fine print using 2.85mm PLA. Any additional recommendations would also be welcome. Thanks.

Is this Cura 3.X?  I recommend you go back to an older version of Cura - certainly 2.7 is safe.  There is much discussion of this here:

Thanks for that gr5. Will give it a go and see what happens.

 Hi gr5. unfortunately, I'm still getting the same result. I've changed the settings and the design but have had no improvement. Any other ideas?

Not even slight improvement?

 

Well I see underextrusion on the top layer before it prints the name.  I would try to fix that by printing a bit slower and maybe a bit hotter.  Try 10C hotter and at 70% speed.

 

Actually I would make some smaller test piece that does this - maybe print just the R.  And play with stuff in the TUNE menu.  Actually it looks like you have some pillowing which is fixed by more fan (you want 100% fan for PLA) and more "top layers".  At least 1mm top/bottom thickness.  It takes quite a few layers for things to recover over infill.  More on pillowing here:
