Cura USB Privileges on Debian
Using Cura on Debian (Ubuntu/Mint/etc.) for your 3D printer but the software isn’t detecting your printer connected via USB? You might find other resources online stating to run Cura as sudo… this will work but it’s not a good habit to be in.
The proper way to fix this issue is to add your current user to the dialout
group in order to communicate with a serial device over USB.
sudo adduser $USER dialout
Log out and back in and Cura should find your printer.
