*****************************************************************************
In order for Cura to communicate with your printer, it needs to run from a
user which can both read and write to it. On Archlinux, this currently means
that you need to be in the ** uucp ** group.

To check and make sure, connect the printer and see who has access to it; e.g
$ ls -l /dev/ttyACM0
