I've been Experimenting with 3d Carving on the X-Carve, and finally took some time to write up my notes and process. In the end, it was much easier the expected, even for a guy who mostly does 3D Printing.http://kansascitykitcompany.com/explorations-and-speculation/3d-milling
Nice write-up. You mentioned that you use Fusion 360 for the CAM tool path generation. Do you use any other software for your G-code? I wasn't aware of Fusion 360 being able to directly drive the X-Carve.
I used Easel's import G-Code command to directly import the g-code generated by Fusion. It was much easier then i'd expected.
realy nice experiment, and many thanks for sharing.i realy need to try this one day, the use of foam to make some try a very good idea !
