Today I just finished getting my fireball V90 setup and have done numerous test cuts on it using some emc test files. All was well until I tried to take some simple 3d models and have meshcam make some g code out of the .
I am using Autodesk Inventor Professional 2011 student edition to generate 3d models. For my first test I simply made a rectangle in inventor 4" x 2" x .38" as a standard .ipt inch file and then exported it as a .STL file.
When I opened meshcam V4 it imported the file just fine and I could see the 3d model on the screen. However when I clicked on the define stock button and clicked fit to geometry it told me I needed a piece of stock that was over double the length, width, and height. For some reason meshcam thinks the files have these ridiculous dimensions when they don't.
So I thought maybe the model was wrong and preceded to try many different models that I have made. Every single one of them had very incorrect dimensions..... I then thought that meshcam v4 was the problem so I downloaded v3 and it still has the same problem.

Does anyone know what the problem is/may be?
I've attached the .stl file anyone with meshcam please look at the dimensions on it. It should be 4x2x.38 for the block dimensions.
