If you have not endstops connected to the Duet, DWC displays status Endstop hit Yes, this is a bit confusing. Maybe it’s possible to have a status like ? if there is no endstop connected.
I would add a link to a troubleshooting guide if the connection does not work. E.g. if the router blocks unknown MAC addresses, conflicting IP addresses etc.
At the beginning I would add “If you have a Duet WiFi, then…”, same in Step 8. It is implicit in the title, but can be overread.
