Hey Liv,
you can use an ethernet cable and benefit from the automatically available Zero-configuration networking (provided by the avahi package installed in the Onefinity controller) to get a link-local address (169.254.0.0/16) automatically assigned when entering “http://onefinity.local” in the web browser on a remote computer attached via the ethernet cable.
Then the Onefinity Controller’s User Interface shows up in the web browser and you can control the machine as usual. You even have the 3D toolpath simulation then (that you don’t have with a display directly connected to the Onefinity Controller)
