Didn't last too long, also brass fitting is not located on the top of my printer? Is that normal? Need some help MP!

It printed about 3-4 small objects okay, then when I tried to print something larger and more complex, the plastic filament got all over and started making a ball.



The nozzle is clogged with filament and so is the heatsink.

The temperature on the screen reads sporadic temperatures of 290-340-450 degrees and jumps around in that area.



Also, I seem to not have a brass fitting on the top part where the bowden tube goes. Mine is not touch screen yet it has the same style top as the new 3D printer that has a touch screen.



Really wish there was an all metal hot-end, sounds like plastic in a metal casing where there is heat up to 400F is a bad idea. Printer lasted 4-5 prints if that, lasted about half a day. Its was a lot of fun when it worked. but now its just been a frustration filled fix. Hope its not a lot of fixing...
