Its good that is in there. BUT... And its a big 'But'. What happens if your controller board locks up? No firmware is running. Or what happens if your sensors fail but not in a way the firmware can detect the failure. I'm real nervous about leaving mine printing unattended, but its not so much from the fire stand point. I'm worried it is going to go crazy and tear itself apart.
