Still cannot print a single nicely finished object ...

[aladar]

I only have the 3.1 Felix printer for less than two weeks but I still could not print anything that was finished, or finished well, this forum was helping a lot to resolve issues so far, but now I'm at the point where I'm stuck.

So here is what happened... the print just went fine till a point when I have no idea why the printed just made a huge nose/splotch at a point. Then it started to run its rounds to finalize the object and when it arrived to that big unneeded part as it cooled after the first or second turn completely the extruder just jumped on it, not sure what else moved at the point but the rest of the object was shifted as well as show on the second picture.

Anyone has any idea? I'm using PLA, felix original. I have a few days left before I must print my objects and it would be terrible to pay money for someone to do it for me while I have the printer bought ....

Please help.
Thanks,
Tamas
