I stumpled across a very cool plugin called "OctoPrint Connection" which lets you use Cura without physical connection to the Proforge 2S. You can simply send it to OctoPrint and it will start printing. It can even show you the live camera footage inside Cura.
Can we get an update of Makertech Cura version to version 4. Currently the newest version is 4.3 . I think is a great time to include all your printers in the official repository.
