Posted · printer produces "bird's nest"

Hello everyone,

I had a little problem with a print.

I wanted to print a rectangular cup 165 x 80 x 95 wallthickness 2.5 mm

I'm using a Ultimaker 3 Extended and Cura 2.5

Material was PLA.

I used standard Cura profil "Fast Print" with 20% infill and 7 mm brim.

First 5 mm looked good:

After that filament lost contact somehow and the printer printed the filament in the air creating what looks like a bird's nest:

Here how it should look like:

Does anyone have a hint for me?

    Did your print get detached from the print bed during the print, which led to this bird nest?

     

    No, the print was fully attached to the print bed. No wrapping at all.

    May not be relevant, but just to be sure, what brand PLA are you using?

    If the print was still stuck, something must have interrupted the layer bonding. The edge of your print looks pretty rough, so there was some minor extrusion all of the sudden, and later, looking at the density of your birdnest-string extrusion seems to have caught up.

    Could be an inconsistency in the filament, or some dirt which clogged your nozzle for a moment.

    Was original UM PLA coming with the printer.

    I think I found the problem. I was also thinking of under extrusion. So I checked the feeder.

    Last week I had a clogged nozzel and the feeder had eaten away a lot of filament.

    So I had to disassemble the feeder to clean it. Made a little mistake at reassembling. I assembled the housing of the feeder in the way that the screw head of the screw that adjusts the force of the spring was outside the housing. So the force of the spring was very low.

    I will try again with correct force and report back.

    Thanks for your help.
