stops pulling filament

[ulticam 0]

Hey,

I have just got my new ultimaker and I am very proud of it sitting on my desk. I've been playing around with it for a few days, however I still haven't had a compleatly successful print.

I've been using cura (this is the only bit of software I could get to talk to the machine + it's definatly easyer to use for a new user). It's seems like the the filament keeps slipping half way through a print and so the top of most of my prints are just a wispy mess.

I thought it might be that I haven't tightend the knob enough but this does not seem to help.

If I controll the printer and jog the extrution along it's works perfectly. It's only during printing.

Just for some info I'm using PLA (that I have mesured with calipers) and Cura ?2.08? (im sticking the stock settings at the moment) on a mac running mountain lion.

It could be possible that you are having the dreadful plugging problem. This usually starts with extrusion problems and slipping filament. There is quite some information about plugging on the forum.

Another option could be a bad bowden tube, which is quite rare, but this means it's hard to push filament trough it even before it reaches the hot-end.

It does feel like it hits quite a bit of friction about half way through the tube (at the peek of the tube) I think I did an ABS fix kit (there was no instructions on how to use it) but to be honest I'm not too sure if I did that correctly.

The ABS fix kit is to stop leaks from the nozzle, the idea is that you extrude the ABS trough the nozzle at 260C so it fills up any gaps, as ABS has a higher melting temperature then PLA you won't melt the ABS at normal PLA temperatures, and thus the ABS will stay in any gaps in the nozzle.

ok cool i did that then, just need to look at the filament now then.
