| [title] Connect to Duet - Linux |
| [* icon_caution] This step is for '''Linux''' users only! See Step 2 to check the Duet is connected and the Serial Port name. Windows and Mac OS users skip this step. |
| [* blue] Most likely, the first thing you will need to do on a Linux installation is to add the user to the 'dialout' group, to allow permission to connect to the Duet. Do this by opening a Terminal window and sending '''sudo adduser [your_username] dialout'''. Following this, you will need to log out and back in, or possibly restart, to enable this. |
| [* blue] There are many options to connect using Linux. Our favourite is to use CuteCom, which is a GUI serial terminal. It's available in most package repositories, or install with '''sudo apt install cutecom'''. It should automatically detect the correct port (usually /dev/ttyACM0), and is configured correctly out of the box. Click 'Open' to connect. |
| [* blue] Alternatively, you can use a text-based serial terminal application such as Minicom. Install with '''sudo apt install minicom''', and run from a Terminal window with '''minicom -s''', which starts it in setup mode. |
| [* black] Select 'Serial port setup', then 'A', and change the port to '/dev/ttyACM0' (or the port name from step 2). Press return twice, then 'Exit'. The terminal will start. Press CTRL-A then W for linewrap, CTRL-A then U for CR at end of line, and CTRL-A then E for local echo. CTRL-A then X quits Minicom, releasing the port. |
| [* blue] Finally, you can use the built-in 'screen' terminal. However, you cannot see the commands you type in, and the responses from the Duet are not formatted nicely on the screen. If you want to use 'screen', do this: |
| [* black] Run '''screen /dev/ttyACM0 115200'''. (Replace "ttyACM0" with the port name if it's different.). You should see a blank screen, but see note on Duet 2 WiFi below.
