I have my UM2 since end of November and I printed a lot with it in the last months.
But now UM2 drives my crazy. My nozzle is clogged all the time and I can´t really use
my UM2 for printing.
a)
I feed filament with "Change material". Filament flows through nozzle. Everything looks fine.
After one minute filament flow I try to start printing. And nothing....
b)
"Change material" again. Filament stucks and I can hear the famous CLICK-CLACK sound
of the material feeder in the back. I help the feeder motor and pull the filament by myself.
And then I can see the clog. Now back to a) and then Issue b) and a) and b)....
Even in my dreams I change filament of the UM2. It becomes a nightmare.
I changed and tried several filaments.
Four original Ultimaker PLA filaments (gold, green, dark-blue and grey)
One original Ultimaker ABS white
One white innofil filament.
I cleaned the nozzle with the known procedures like

or

Maybe the community could help? I am really frustrated.
I love the print quality of the UM2, but the filament handling drives my crazy.
I have a new nozzle from Ultimaker in front of me, but It looks like rocket-science to me to
change the nozzle. Could someone please tell me how to change it?
Pictures would be great.
