printisans

Hi All, I am using an Ultimaker 2 and found out it is sometimes difficult to finish a print. The first half of the print normally goes very well but it has no materials coming out from the nozzle after 2 hours print. Any ideas about what is going on? The nozzle seems ok since if I forward the material next time, it will has material coming out.

Thank you Daid. Is there a third method to solve this problem? Based on my knowledge and other user's feedback, when import stl. in Sketchup, it gonna take a while (someone said up to 1 hour) to load the design. I do not know if it happens to you or maybe other software can do the trick? Thanks again!

Hey guys, when I want to import .stl into DSM, it is works, but the status of the object is mesh, which means I can not modify it, even can not select it. I searched hours for this problem but seems like every except me works pretty well when importing .stl. I find DSM online help http://help.spaceclaim.com/dsm/2012.1/en/File_import_and_export_options.htm But my DSM does not have "3.Solid" option. it that the reason WHY? Any suggestions? Thanks.
