DD2 only the fan turns on and the wheel rotates 1/4
This was working fine yesterday, this morning, it will not power up. When you press and hold the button on the back or the button on the emergency stop, the fan runs constantly and the wheel turns a few degrees anti clockwise. There are no lights on the LCD display and the computer is not recognising the hardware. As soon as you release either power button , it just stops. I have tried reloading firmware, no good.
Any thoughts appreciated
