Once you have created your Gcode toolpath in Fusion 360 or other CAM software, you will need to transfer it to the machine in order to be able to run it. Note that Gcode files must be 2.5MB or less to transfer. This is also the maximum file size that the processor can handle when it comes time to check the Gcode for errors before running it.
Using the drive on the BeagleBone while you are connected via USB to the machine is the most simple way to store files. To do this, drop your nc file directly into the "BeagleBone Getting Started" drive.
Once you are logged into your machine, click File - Open, and then navigate to /media/beaglebone as shown below to find your files.
You can also transfer files using a USB memory stick directly connected to the machine. This is especially useful if you are using the machine stand -alone with an HDMI screen. The USB port is the lowest port on the machine(see photo below).
Once you have plugged in your USB port, you can navigate to your Gcode in AXIS using the File - Open command and navigating to /media/USB_DISK as shown in the photos below. Once you are in the folder, you will want to view all files to make the Gcode files visible.
