Had no luck getting them to connect when I tried, the 3d fab computer connects to the internet now but just can’t get octopront to work
Connect a monitor to OctoPrint and check the IP address in use.
Then try connecting to the IP address.
I sometimes find Windows won’t find my printer when using "printer.local " naming until I have connected via IP address.
If the printer has an LCD then there are Octoprint plugins to display the IP on the LCD at boot time so you can always at least connect via IP.
If you can’t connect via IP then something more fundamental is broken (not on the network, not on the same network, Octoprint didn’t boot, firewall etc…)
