Bah! Its not sorted. The firmware I found was not the
actual Creality firmware, but something reverse-engineered by someone to what they think it should be
As such, it prints, but is missing fairly important features like load and unload filament
The only official Creality firmware I can find is 1.1.8 which runs like crap.
Ray, Andy - how comfortable are you guys with running command line stuff to extract the firmware from your printer? I've found a utility to do it and tried it on mine. It will extract the actual Creality firmware which works (1.1.6 or 1.1.7 not sure) to a file so I can re-flash it on to mine.
