Possible PVA Under-extrusion?

Recommended Posts

Does it pop and crackle when you print? If so, it is too moist. PVA of any kind will absorb moisture like you would not believe.

Do you have anything to adhere the print on the buildplate? Have you done proper leveling? Is your nozzle clean on the outside? Have you done hot pulls or cold/atomic pulls to make sure it is flowing inside the nozzle?

I lean towards the moist PVA because of the blackish blob. That happens when there is a bit of burn off of moisture and the carbon collects on the nozzle.
