    Hi All,

    I have a 0.4mm volcano NozzleX nozzle that I have been using for about a year now - I have printed maybe about 5kg of filament with it. Some PLA, some PETG, some Polycarbonate.

    After the last swap from PETG to PLA, it is suddenly extruding filament that I have measured at approximately 1mm to 1.2mm diameter.

    What is even stranger is that it seems to be almost elastic! When I manually extrude via my printer interface, when it stops, the filament literally sucks back in (no retraction on manual extrude) and then oozes out.

    PLA filament is Hello3D Silky silver 1.75mm filament. I have not really printed much with this filament before so I'm curious if any of you have seen such behavior?

    Thanks

    Update: The filament prints fine - nothing wrong with the nozzle. It's just how the Silk PLA behaves when extruded into the air.

    Lesson learned!
