It sounds like you checked the "print a mold" box. Cura can do this. The part is then made of air surrounded by plastic. (People do this so they can fill the void space with resin or maybe wax to make a candle. It is a REALLY good way to make a shoft rubber over-molded part. Let's say you made a hammer handle in steel on a lathe. Place it inside a printed mold and pour in the rubber and get finger grips over a steel shaft. It's useful but not now.)
If you didn't evidently click "mold" then there is something wrong with the STL file. The file SHOULD specify which side is the inside and which is the outside. This can be messed up. Without knowing the history of the STL file, I can't say. Send the files, The STL, and the *.3mf files you get when you do File->Save in Cura. (.3mf has all your settings) Are you making the file in openscad? f so it is easy to make an unprintable model. It is a topological thing where what you actually made is the inside of a pulley. I guessing blind here. -- Chris Albertson Redondo Beach, California _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
