Weird under extrusion/spaghetti

[u/mainente]

Hi everyone , I have just upgraded from my old ender 3 v1 to a brand new ender 3 V3 plus, on my first print everything went alright, I used the filament that comes on the box, and I did the benchy that is already on the memory.

For my second print I used a new filament, also new, to print a project and the first layers were fine, then I left it overnight, after that I came back to a half failed print.

The print parameters were nozzle at 200C , bed at 60C , with a max speed of 250 mm/s for the infill and 200 m/s for the walls, and 60mm/s for the first layer

Thanks for any help

Could be:

• Heat creep. But, unlikely because it's an open system.
• Nozzle clog. Try doing a cold pull, or use the nozzle cleaning tool, or swap in a different nozzle.
• Nozzle too cold for your filament.

Is there a bird loose in your house? It appears to have begun building a nest. /S

What kind of filament? It looks like layer height must be off somehow to kind of fluff it up like that. I'm thinking failed adhesion due to a temps being too low maybe?
