Hi all,
it looks like there are some important parts missing from the hot-end assembly, especially a hollow-lock set screw like this one: http://www.mcmaster.com/#set-screws/=uzrymv
This hollow-lock screw holds the PTFE lining inside the nozzle holder: http://reprap.org/mediawiki/images/thumb/8/8c/Jhn_nozzle_holder_v5_metric.jp...
If this screw is missing and the PTFE lining is loose, the filament has not sufficient guidance while it is beeing fed into the melting chamber and the molten filament can completely mess up the hot end.
I have no idea who played around again and just put the broken 3D printer back without saying a word, makes me sad...
Please be a little more disciplined when working with expensive and maintenance-intensive machinery.
I'll try to get the parts tomorrow,
Where can I get a screw like mentioned above? (5/16-24 hollow-lock socket set screw )
Where can I get PTFE (vulgo Teflon) tubes? (metric: 6.35 mm OD, 3.175mm ID)
Greets,
MiKa
