mine 1.0aio on the newer board got flashed recently, its much better but there is potentially a lot more learning to do. but that’s a good thing. you can actually change the bed and extruder temps and axis speeds and a whole host of things that can give a real boost in print quality. but on the down side is you can send commands that might make the printer crash or not work right. once your familiar with putting jobs in that software is basically the same, place stl, slice, print, monitor. I’m finding it nice being able to print a test, pull it of and print it again without waiting 20mins to go to the bottom back to the top heat back up again etc as i can just say not to turn things off on finish, manually lower the bed enough to get the job then re-home and run.
the biggest reason for me flashing was that i bought xyzzero cart thinking i could reset the length of cartridges but more importantly the temperatures but it turned out while it did reset the length it ignored everything else and both bed and extruder were too low, they worked but had problems with job peeling off bed and not sticking.
hope that helps you decide
