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.

@Makertech The workaround previously posted for the Makertech Cura does not work at all on Catalina, which means my printer is basically bricked at the moment. When can users expect to get an updated build of this? Alternatively, please can you share or export the Proforge settings so users can use the official Ultimaker Cura software and customise that instead.
