@droftarts thanks,
Ive got the firmware re-flashed to 2.05.1 with Bossa
I ran the RepRap firmware configuration tool and generated the system files, as it states I put the Reprap Firmware file in the /sys directory, the web control bundle in the /www directory and the system files into the /sys directory.
I cannot connect to the duet via DWC however (checked IP settings too).
I restored the card back to its backup manually and was then able to connect to the printer via the previous IP address, I was greeted with a new DWC page so it looks like the firmware update has worked.
I have tried as the config tool also suggests uploading the configuration bundle zip file via upload system files in DWC. When I do this, it creates another /sys folder within the directory and puts the new files in there.
However I don't think its reading the config files properly.
I can take manual control of the printer, heat the heaters.
I cannot however select files to print - I can see them and tick their box, but don't know how to print them.
Theres a new option 'load filament' which when I click it returns the error 'failed to load filament'
Ive tried various incarnations of moving the files round and nothing seems to bring the right results.
What have I missed? Apologies if its something blazingly obvious.
Thanks
