How to remove broken filament

[choco 0]

Hi,

My PLA filament broke mid-print while I wasn't watching the machine. I opened up the feeder and tried to pull out the filament in the Bowden tube but only succeeded in breaking the PLA again ... this time right at the bottom of the "quick fit coupling" that's embedded in the feeder. Now I can't access it with long-nosed pliers and have no idea how to get it out without undoing the entire feeder (which I REALLY don't want to do!)

Can anyone advise on how to extract the broken filament? Perhaps by removing the bowden tube from the top of the "quick fit coupling"? ... but how do you do this safely?

Thanks in advance,

Choco.

Push down on the topmost part of the coupling and then pull the tube out. Remember to heat up the hotend before pulling out the filament

Or if you want to be lazy simply feed some new PLA in there and keep printing.

Just to clarify... you need to hold down the upper part of the coupling, while at the same time pulling the tube up and out.

Thanks for that advice.

I tried pushing the PLA through but it ended up being a blob stuck in the hot end.

I followed these instructions: http://wiki.ultimaker.com/Jamming

and it's all working again now.
