Once you have created all the toolpaths you need, you can save out the different toolpaths for your machine.
Select the appropriate post-processor for your machine. It is likely that your machine has only one post-processor, but if not, then use the one suggested by your machine manufacturer.
Select each toolpath you wish to save by clicking on the checkbox next to the toolpath name.
Then click on the 'Export' button. This will post-process the selected toolpaths and they will automatically be downloaded to your computer.
