    I see, that explains a lot. It always reads like people have to go through a lot of fuss to store their PLA filament properly. Just wondering: What exactly do you mean by "oiler attached"?

    An oiler basically allows you to add a small amount of vegetable oil to the filament as it is passed to the hotend. This prevents the PLA from jamming up/clogging.

    I see... Thanks for the explanation, and link. But I never had any issues with jamming or clogging, at all, so far. PLA is really graceful on my end, it prints just flawlessly all the time. :) The only issue I'm still facing is printing very flexible materials like NinjaFlex - they'll still curl up in the extruder, in spite of the E3DV6 upgrade, and a rather long PTFE tube all the way up to the hobbed bolt. Still working on that.

    humidity, sucks and i think its effecting my prints. its been a ridiculously muggy summer hear in Nebraska so i got fed up and and bought these reusable cell phone silicone dehumidifiers and threw em in a box with my filament like so. hopefully we will be in business soon.

    Yea, minimizing the water absorbed in the filament helps (some filament types more than others--nylon really sux 'wet').

    really? My nylon seems to be very wet. Only thing it does is when Its first heating up, it oozes a bit more than it probably could.
    Constant jet of steam and very nice prints.... when it doesn't warp.

    I've been printing on straight perfectly clean glass or on glue stick. I imagine the texture would be a bit more smooth if it were dry and I might be able to print higher resolution... but man... I don't see the big deal with wet...
    This guy says its a must to have "some" moisture..

    As the filament gets 'wet' it leaves steam (bubbles) in the print. More moisture->more and larger bubbles.
    At some point it will impact the print quality. Most of the time it is not enough to make a noticeable impact.
    Nylon is the one that has reacted the worst to wet conditions in my prints. I just keep it dry.

    His 'spikes' theory makes sense for mechanical parts. I've noticed that the wetter the nylon is, the more stringing you get.
    A lot of people are bothered by the hissing and what not that you get with wet nylon.

    I've had issue with some filament being too dry and kind breaks at a slight bend.

    If the filament has too much moisture it will put holes in the print due to the exploding moisture bubbles.
