<br>
it looks like there are some important parts<br>
missing from the hot-end assembly, especially<br>
a hollow-lock set screw like this one:<br>
<a href="http://www.mcmaster.com/#set-screws/=uzrymv" target="_blank">http://www.mcmaster.com/#set-screws/=uzrymv</a><br>
<br>
This hollow-lock screw holds the PTFE lining<br>
inside the nozzle holder:<br>

<br>
If this screw is missing and the PTFE lining<br>
is loose, the filament has not sufficient<br>
guidance while it is beeing fed into the melting<br>
chamber and the molten filament can completely<br>
mess up the hot end.<br>
<br>
I have no idea who played around again and<br>
just put the broken 3D printer back without<br>
saying a word, makes me sad...<br>
<br>
Please be a little more disciplined when<br>
working with expensive and maintenance-intensive<br>
machinery.<br>
<br>
I'll try to get the parts tomorrow,<br>
<br>
Where can I get a screw like mentioned above?<br>
(5/16-24 hollow-lock socket set screw )<br>
<br>
Where can I get PTFE (vulgo Teflon) tubes?<br>
(metric: 6.35 mm OD, 3.175mm ID)<br>
