Using F360 is pretty straightforward. You will need to save your toolpath (gcode) in F360 using a Grbl compatible post processor. Then you will use a gcode sender like "Universal Gcode Sender" to send the gcode file to the Arduino/Grbl that controls the X-Carve.
So no changes to your hardware are needed. Just download Version 2.0 of the Universal Gcode Sender at this location http://bit.ly/1hftIhy
The UGS is a Java "Jar" file, so be sure you have the latest version of Java loaded on the computer that is connected to the X-Carve. Unzip the UGS file and double click the JAR file and UGS should start. Use the File tab to load the gocde file you want to use. Zero the machine and then "Send" the file to X-Carve.
I use Dropbox to get my gcode files from my design computer to my shop computer, but you can use your home network or just copy the file to flash drive and carry it.
Let me know if you have any questions
