In this Instructable, I'm going to show you how you can take your 2D part, designed in Autodesk Inventor, and export it for use with a CNC router.
The first time I tried to do this I kept running into issues. There are a couple of tricks that you need to do to export your part correctly so that your CAM software (I'm using VCarve Pro) can correctly generate toolpaths. I'm going to write this Instructable so that people don't waste time like I did trying to figure out why errors kept happening.
I did this at TechShop, where they have a CNC router and all the software that you would use to do this.
After you've designed your part, right click the face. Since this is a 2D part, we don't have to worry about grabbing anything else. All we need is the face. That was my first mistake!
Before saving it, we must change some of the advanced options. Click the Options button to open another dialog. VCarve Pro 6 (the version TechShop is using), requires a specific DXF format, otherwise it will throw an error message that isn't very helpful. That was my second mistake! Select R12/LT 2 DXF and save.
