Windows users:

After the COM port has been configured, send command M115 to the Duet board.

The Duet will return the firmware version being used.

Mac users: You will not see characters appear on the screen as you type. For this reason, it is easiest to copy and paste the commands to ensure correct syntax.

Copy M115 and paste into terminal and then hit enter. You will see OK when a succesful command is received. Wait a few moments and the firmware version will be displayed.

Once you know the firmware version your Duet is using, check for the latest version of the firmware in our Github repository here. Use the 'Latest release', not any 'pre-release', 'beta' or 'RC' version until you are familiar with Duet.

If your Duet is using an old firmware version, we recommend upgrading. See Installing and Updating Firmware documentation.

Mac Users: Any double quotation marks must be sent as straight double quotation marks. Curly double quotations will not work. To enable straight double quotation marks go to System Preferences > Keyboard > Text. Then under the Double Quotes drop down, select straight double quotations.
