Knobler

I got within one week a total loss of all mainfunctions of my UM2+ as: the heatplate didn´t heatup anymore a few days later the nozzle didn´t heatup at all So no printing doesn´t start anymore, even as curiously the heating works in the advanced maintenance menu. My idea is, that there may be a defect with the mainboard. Or has somebody a better idea or fixed a problem like this already.
