After updating firmware my UO came back to life (at least partially). I should have done it at the beggining, I suppose, but I'm a total begginer at this field (it's my first 3d printer).
So what have changed:
- ultimaker controller screen now works fine - I can navigate through menu,
- y and z axis motors work fine.
What doesn't changed:
- I still can't switch Ultimaker off by using side switch,
- x axis motor and extruder motor doesn't work (but it's not a motor failure - when I changed x and y motor plugs on the shield, x motor started to work),
- when I choose "Preheat PLA" option, "preheat failure" text showed up and the screen began of controller started to blink.
So I'm miles ahead, but still not there. Anybody have an idea?
