On my S5 it ran out of PLA filament overnight last night. The filament end is in the extruder housing, the bed is still hot. But the screen is totally black and I cannot get it to respond with anything. The bed has dropped fully down and the head is in the front left corner. What do I do now? I have tried to load new filament it goes into the extruder housing but won't "clip", and doesn't do anything to resuscitate the screen,
