    Hello,

    I hope that I'm posting this in right section...
    I have problems printing with polycarbonate filament.
    using e3d-v6 bowden, 3mm, 0.4 mm

    here is what happens:
    https://propellered.com/images/image16.jpg

    that's printing with vase option turned on and 0.1mm layer, but same happens with 0.2 and 0.3 layer,
    every time I tried to print...

    it's like there is some other plastic in filament, and every now and then it blobs out huge drop of liquid plastic
    and ruins a print...

    any ideas?

    thx

    I would try turning the temperature down about 5C.

    I tried every temperature from 260 to 280 C!!

    Edit: tried even at 250C, and after one hour same, big blob of liquid plastic that is fragile, and has lower melting temperature.
    I'm out of clues...

    Honestly, it sounds like you have a defective roll of filament.

    PC can be sensitive to moisture, you may want to try drying it.

    I think that that could be a case, but I wan't to test every other possibility before...

    I tried, in owen on 90C for 2 hours, same... only difference is that small bubbles are gone,
    but I don't have problems with steam bubbles, it's something else...

    May I ask who the manufacturer of the filament is, or is this an Ebay no name?

    I have used that PC with great succes, but i was printing at 295C. I might be wrong but in my experience the low flowrate of the small layer printing doesn´t help you either. As i recall most of my printing was done at .25 or .3.
