File Format For Loading Files onto a USB stick

If your going to use a usb stick to load your gcode files, make sure your usb stick is either partitioned in the NTSF or FAT32 format. Using any other file type may not show files on the controller.

USB sticks must be 2.0. USB 3.0 sticks may not be detected. Some USB sticks larger than 32GB may not work with the raspberry pi.

File names must not include the . (decimal point or period) character. Your file will not show up if it includes this special character.

The controller will not recognize non-gcode files, such as the CAD (design) file you make gcode with (for instance, If you are using Vectric VCarve and you hit save in the upper left, it creates a file ending in .crv . This is the design file not gcode and the controller will not recognize it.
