Extruder screw loosening after a couple of layers

[erwin! 0]

Hello,

First, i just build my Ultimaker in the last month and i don't have much experience with it but i do know how to work with it pretty well. And since i'm only 16 and i'm from the Netherlands my English isn't that good yet.

I've been printing some objects with my printer and it was all looking good until ± a day ago, every time i try to print something the screw from the extruder get's less tight after a couple of layers and the filament isn't going though anymore and my prints all get messed up.

I've tried using tape to make it not able to move but that doesn't seem to work as it get's looser without unscrewing itself :?

Thanks In advance for any help,

Erwin

Hi Erwin,

Did you use a Nylock lock nut inside of the mechanism? One of these:

It's the nuts with the blue rings inside of them, they are a bit larger, and they also clamp a lot harder on the screw making it almost impossible to shake lose.
