    He means the one you have to flip the printer upside down to see.
    Make sure it is running when the printer is on.

    Any of them. Frankly ANY vegetable oil will work, but canola is preferred.

    You normally print an oiler that holds a small bit of sponge with a couple drops of oil on it. Then join that inline.

    Do you have some sponge or a paper towel?
    Do you have tape?

    Tape the sponge or paper towel around the filament where it feeds into the extruder.
    Add a few drops of oil.
    Print an oiler.

    You want just a very fine sheen of oil on the filament after it passes through the oiler (or your home made rig)

    Your call.
    I do it any time i am using PLA.

    Seasoning is temporary on some nozzles and must occasionally be redone.
    I just leave it

    Good point... Just remember, too much oil makes bed adhesion an issue

    Eh, I dispute that :)
    I have had oil puddle up on the print and it still sticks fine, but I can see where it might matter.

    Either way too much oil makes a mess at least and might cause other issues, Just a fine sheen...

    I think you'll be fine. Looks like simple objects are going OK for you. Just the more complex versions are causing you pain. An oiler with PLA is folks insurance to use all the time.

    To good luck... Cheers

    Have you run the model through something like netfabb or similar to so any repairs on it needed? Is this model you are printing publicly available? Wouldn't mind seeing what it is you are working with.

    yes I've ran through netfabb.. and I've tried 2 different files.. for whatever reason it's like the filament doesn't stick to itself.. I just had to scrape the base layer off of the glass because it was on there so well.. I've printed the file before[​IMG]

    Have you tried cutting your speed in half to see if it will finish?

    Mine runs almost max speed. Alot of tuning :) cut your speed to 20mm/s or so and see if it works better.
