Is is possible to design something with Shapr3D and export it to be milled on the OtherMill or another CNC machine?

Thanks

If I recall correctly, you can’t directly use an STL with OtherMill. You need one extra step. What you need to do:

1. Export a high quality STL from Shapr3D
2. Convert STL to a G-Code file with a converter
3. Use this G-Code with OtherMill

Here’s the detailed description:

Save or export your file as G-code with an .nc or .tap extension. If you don’t have a post-processor for the Othermill in your CAM program, you can use any generic post-processor labeled “mm/arcs.”

They have more info and converter recommendations here:

Thanks Dennis. I’ll give it a try when I get some free time…school just  
started so that might be a few weeks.
