[Print head problem (death rattle) - solved]

I've encountered a new type of problem I've never seen before. The print head acts all wonky when it is about to start print/level printing bed. It only seems to act like this in the "starting corner".

 

[Material gets stuck in tube - solved]

No more getting stuck in the tube and grinding of material =D. Finally I can start printing things with quality and reproduce the results. Thanks for all the help!

 

[Material gets stuck in tube - solved]

Thanks you all for the insights and tips. The fan in the back was not spinning at all. After a little trouble shooting I found out that the reason for this was because the connector attaching to the arduino board was intalled the wrong way :mad: . After I flipped the connector the fan started to spin (for the first time...). Hopefully it will now work a lot better.

Regarding the chewed up material in the back. What can I do about this?

 

[Material gets stuck in tube - solved]

I can't get my UM2 to print properly. The material gets stuck in the lower part of the tube after a couple of minutes.

 

I would imagine this to be caused by the temperature beeing to high together with a slow speed but I have followed other peoples settings where they have gotten good results. The printer is located in a quite small room that can get pretty hot sometimes, could this be a part of the problem?

 

Printspeed: 40mm/s

Temp: 190°C

layerheight: 0.2mm

 

 

[Printing problems]

Yesterday these settings printed just fine (I printed that cube puzzle that came on the ultimaker sd card with great results). On the ultimaker I had set the speed to 60%, bottom plate to 65deg, and nossle temp 230deg.

Today I get this??? When I aborted this print the nossle was a couple of mm above the plate and no material was beeing extruded. What might cause this?
