Actions in Adobe software are shortcuts to perform tasks that you perform frequently. The process is pretty simple (and this isn’t a tutorial on how to do it) - in that you just create a New Action and then record the process of what you are doing. When you’re finished, hit stop.
One of the things I try and do with almost every Illustrator document I’m sending to the Glowforge is convert the artboard to 20x12". Attached is an action to do just that. You may have downloaded a file from somewhere, or trying to convert old files, or any number of reasons - but this gets you the 20x12 format that works great with the Glowforge.

To install an action -
Download the ZIP file and decompress
Move the .aia file to your Presets/Actions folder. On a Mac this should be: Applications/Adobe Illustrator CC 2017/Presets/en_US/Actions. On a PC, it should be: C:\Program Files\Adobe\Adobe Illustrator CC 2015\Presets\en_US\Actions.
Open Illustrator and open the Actions Panel (Window > Actions). Select the dropdown menu at the upper-right of the panel and choose Load Actions. Browse to the Presets/Actions folder where you dumped the source file and select it. This will create a new area for Glowforge actions.
If you make actions that you feel are useful, feel free to post them to this thread and I can update the zip file as we go along.
