When I click connect in Pronterface for it to connect to my 3D Printer (a Rigidbot) I get this error message:
stty: /dev/ttyACM0: Permission denied
[ERROR] Could not connect to /dev/ttyACM0 at baudrate 250000:
Serial error: could not open port /dev/ttyACM0: [Errno 13] Permission denied: '/dev/ttyACM0'
[ERROR] Could not connect to /dev/ttyACM0 at baudrate 250000:
Serial error: could not open port /dev/ttyACM0: [Errno 13] Permission denied: '/dev/ttyACM0'
I have tried different baud rates but all come up with the same error message. I am running Ubuntu 14.04 on a Dell XPS 13 9343 (Developer edition).
What else can I try to connect to the 3D Printer?
