I've tried and tried to find an answer to this.
I started modeling in inches, object is 4" sphere. Export as .obj or .stl and both come into Cura as 8mm. So I read that I need to model in mm. So I started a new file with units in mm. Created a 101.6mm sphere, exported and imported into Cura. Still imported as 8mm.
I'm working with a trial version of 3d Studio Max 2014 and the newest version of Cura.
Anyone have a clue why this is doing this?
