Changing Ultimaker 2 nozzle
!
Story:
Since weeks I had several problems. „Error Stopped Temp Sensor Bed" and clogged nozzle.
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....
"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.
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.
Even in my dreams I change filament of the UM2. It becomes a nightmare.
After contacting the Ultimaker phone support they sent the following spare parts for free:
- Heated bed
- Red clip
- Grey tightener
- Nozzle

First I changed the heated bed.
But the clogged nozzle nightmare
went on and on and on. Sometimes
I was lucky and I got printed some
small objects, but every time I
switched the filament I got the
clogged nozzle issue.
So I dismantled the whole extruder
and boooom.
I knew where the big problem was.
