The New Hotness

  • Makergear M2 V4 Nozzle: More Silicone!

    A Makergear forum discussion on PETG hair and the prevention thereof prompted me to take a look at the silicone coating I’d applied to the nozzle:

    M2 - nozzle silicone - applied
    M2 – nozzle silicone – applied

    That was ten months ago. This is now:

    M2 Nozzle - worn silicone coat
    M2 Nozzle – worn silicone coat

    The camera sees the nozzle in a mirror laid flat on the platform, making the image less crisp than a direct view.

    So the silicone seems a bit worn around the tip, has acquired a few firmly adhered globs, and definitely isn’t as shiny.

    Rather than (try to) peel it off and reapply a new coating, I picked off the globs, cleaned around the nozzle, and slobbered a thin layer atop the existing silicone:

    M2 Nozzle - more silicone
    M2 Nozzle – more silicone

    Extruding a few millimeters of filament pushed the film off the nozzle opening and it now works as well as it ever did.
