I've had mine for about a year.
UI Blue + 1.0
I've long suspected that Qidi does not update the firmware because either they haven't implemented a method on the board for remote flashing, or they don't want to so easily expose their code to reverse engineering. I, for one, would love a flash utility so that I could flash it with a more mainstream Marlin. I love my printer, but the only innovation I see in it is the model display on the LCD while printing - and you only get that if you are using their captive slicer. Neat, but a waste of both bandwidth and memory. Otherwise, their implementation of Marlin is somewhat handicapped with many standard Marlin commands that do not work as they should - if at all - on the beast...
