Fixed all errors by installing 3.2b1 via bossa after resetting the board and then apt get for DSF DWC, had to reset the firmware as updating to the stable feed and going back to 3.1.1 was still giving the lost connection no data error every couple of seconds.
Now done a few small prints printer on for a few hours now with not a blip.
Again not sure if relevant to anything or anyone.
Cheers
