I just changed my nozzle on my Anet A8 after it was fully used up. When I started printing with my new 0.4mm nozzle (same as before) my extrusion was VERY bad and inconsistant, even so bad I couldn’t continue printing because it would pull the first layer off.

If I compare it to my extrusion before the nozzle switch, it is really bad, even though I tightened everything as before. I am quite sure it doesn’t have to do with adhesion to the heated bed since I use tape with pva glue.

Any advice on how to remove this under extrusion so I can continue printing?

All the specs:

  • 25mm/s first layer print speed
  • 200C nozzle
  • 60C bed
  • PLA materia;
  • 0.4mm nozzle size

Let me know if there is anything else you need to know.

Check your extruder feed wheel.
And maybe your previous not used up.

Possibly obvious question but you didn’t say in your original post so I just want to check. After replacing the nozzle, did you re-level the bed?

Looking at your picture, it looks to me as if your nozzle is too close to the bed. You will need to re-level the bed.
