This should really be split into a “Just brought a new system” and “upgrading an old system” page.
Its really difficult to work out that all you want new users to do is go to a specific webpage (not “check here if you have the right firmware” -> “download firmware from here”) extract two zips, locate three file (incidentally the DuetWebControl is currently AWOL and both zips have web pages of 404 errors), upload them in any order and then execute a M997 S0:1:2 command.

Step3 implies 115200, if you set this then it connects and runs code, but I cannot get the Wifi to work, changing it to 9600 fixed this. Is that expected? if so you should be explicit about baud rates rather than expecting people to keep to “default settings” which may differ from program to program.
