Hi there,
after some initial problem I got some very, very nice prints from the Ultimaker 2! It finished some marathon prints last week resulting in a http://www.thingiverse.com/thing:164317 at 0,05mm. It looks awesome and the two pieces come together nicely.
After these print I changed the material (Colorfabb's Woodfill). I wish I didn't...
The material change was OK, material was flowing nicely without problems but during the first print, things went wrong. On the first layer I could see just a few normal lines but extrusion stopped pretty soon. The temperature was quite high at that moment (250) to see it the material gets through. I also choose a rather thick layerheight at 0,2mm.
Now, no matter what material I try to print or at whatever temperature I select, nothing comes through the nozzle anymore. I tried to go back to the Loggerhead's color and also tried a new spool. That, like I expected, didn't give any good results.
What's the best way to get rid of the nozzle jam?
