Just got a mini, and installed the cuar software on a small laptop running Ubuntu 15.10. It failed to autodetect the serial port but after fiddling about with the machine settings and serial port managed to get it to work. I also ran
sudo usermod -a -G tty $USER
sudo usermod -a -G dialout $USER
sudo usermod -a -G serial $USER (got an error on this one)
The second print went wrong. I’m guessing it was a problem with cura as I found the software in a hung state, so I decided to install on my main Ubuntu 15.04 pc. Got everything set up but I keep getting the Error: Failed to autodetect serial port.
Did all the same things but still no luck.
After checking on the internet a bit, I ran cura as root and then it connected. Has anyone come across this? What am I missing to get it to connect without running it as root.?
Some more info:
ls -ld /dev/ttyACM0
