Prints only two or three layers

Posted · Prints only two or three layers

We received the Ultimaker 2 printer two days back. Today, we did the calibration and tried to print the UltimakerRobot. It printed the base (two or three layers) and nothing else.

Please see this video: https://drive.google.com/file/d/0B9v6i29l2SsgWjZfNGhfUWpsTm8/view?usp=sharing

Motor associated with the filament: (last part of the video): Why is it turning clockwise and anticlockwise? Is it an expected behavior?

Please let me know what the issue is and what should be done to fix this.

Thank you.

    Next time try to stop it from printing much sooner. At this point your filament is probably ground to dust in the feeder so you will have to fix that issue first.

    Not sure why it stopped. It looks like you have 2 different colors though? White then gray?

    I'm thinking the gray filament never loaded properly. I always cut the tip of the filament to a point before loading - you probably have the filament stuck just at the lip of the white part (the teflon part) inside the head. After fixing the other issue try "move material" and move filament up and down until it gets past that ledge and it starts extruding. Extrude for a while to get any burnt PLA out of the nozzle.

    Now to your other issue - likely ground filament. First turn off power and pull firmly out the bottom. If the entire filament comes out then yay - just cut it off and throw it away and reload (but now with sharpened tip).

    If the filament breaks at the feeder then remove bowden from feeder: remove the horse shoe shaped clip, push down hard on the outer white clip and then lift firmly on the bowden (the clear tube) (again this is at the feeder, not the head). Do not lift on the bowden untill you can get the clip to go down otherwise the metal blades in the bowden holder will scratch up your bowden (not a disaster but you can only do this so many times - if you scrape badly you can always cut the last 2mm off the end of the bowden).

    Now you should be able to pull the filament up through the feeder and then out through the tube - throw it away and put it back together and start over.
