Hi. I’m trying to set up Astroprint on my raspberry pi 2 for the first time. I just had Octoprint sucessfully installed. I have a wifi dongle, but are trying to connect the unit by ethernet, as I read you actually need 2 dongles for hotspot connection. But when I am trying to connect to the assigned IP address (ssh), I get connection refused (port 22). I have added a file called “ssh” to the root of the SD card. I have also installed AstroPrint app on my mac, but it doesn’t find anything when searching. Is there any way to see the local name so I can try to access the web UI, or how can I access this thing?
