improving print quality, any help/experience?

[xonegon 0]

I'm trying to improve the print quality one my ultimaker, you can see the tiny blobs on there.

 

• 
  too much filament = correct diameter?
  to hot currently 200°C ?

 

Also the top extrusion is very bad, it ruined the piece...

Using Cura 10.9 an mac.

Mendelworld PLA filament "3mm"

 

the back worked out great.

While I'm no expert, I think there are a variety of things that can cause this. Things I would be looking at:

 

• 
  Size of filament setting matching the actual size
  packing density
  minimum layer time
  minimum feed rate
  Fan on or off
  speed of printing
  layer size. Looks like pretty big layers.

It's definitely bad cheap filament, the red filament delivered with the ultimaker does not show these blobs.

Measuring the filament it varied from 2,76mm till 2,92mm.

So I guess this topic should really be in the cura section.. :roll:
