Just an update if anyone reads this thread in the future and wants to connect to their FF.


My board is a Flashforge Creator REV C mightyboard (ATMEGA1280), and although the link that Geoff posted suggested 57600 baud rate, it works with the default 115200 through GPX.


$ sudo gpx -s -b 115200 -v move.gcode /dev/ttyACM0
