STL problem?

My Darwin is getting ready to come to life, so I thought it would be good if I had a simple test STL of know dimensions to calibrate against. I am using Autocad Inventor 11. The test file is a 20mm cube inset from the origin by 2mm in X&Y.
Rhino reads and displays this file just fine. When I run reprap host, and open the file nothing appears. If I open the minimug it displays fine. What did I do wrong?

All help appreciated

I imported the file into Art of Illusion and then exported it again. The exported file works with RepRap. As far as I can tell, the major difference seems to be the number notation. The first file has lines like this:

facet normal -1.000000e+000 0.000000e+000 0.000000e+000
outer loop
vertex 2.000000e+000 2.200000e+001 2.000000e+001
vertex 2.000000e+000 2.200000e+001 0.000000e+000
vertex 2.000000e+000 2.000000e+000 2.000000e+001
endloop
endfacet

...and the second one has this:

facet normal -1 -0 -0
outer loop
vertex 0 20 20
vertex 0 20 0
vertex 0 0 20
endloop
endfacet

I'm guessing RepRap is having trouble with the "e" notation.

That's what I think as well.
The stl ascii file format spec.says that all the numbers are single precision floating point. Sounds like the reprap stl parser needs a little work.
My next step was going to be loading up AOI to do the same thing.
Thanks for the help.

Best,

Is this fixed yet? I would love to contribute to this project, I don't know how to make a real RepRap but I certainly can contribute with the source code!

Congradulations to you guys for inventing this machine! It sounds awesome, it's just what I always wanted. If we can make this replicate itself it will be the last household appliance anyone will buy, everything else (kitchen sinks etc.) can be built by it (theoretically).

In a few years I plan to build one after I graduate college. Has anyone made a RepRap emulator yet? Just a 3-D version that runs the same software but does not need any real hardware? Would this be a welcome contribution or does it already exist?

Is this fixed?

I don't think so.

Read about the reprap host software. The software has a built in viewer. The software previews the part to be printed layer by layer just as if it were running the part on the machine.
