I recently purchase a MendelMax 1.5 from 3D Factory. I have been unable to get the heated bed to work. I am totally new to this, so please be patient.
The LCD always displays that the temp of the bed is either 78/0 or 77/0. The Thermister was connected to the T1 and the heater to D8. While running a part without heat on the heatbed, the thermistor wires melted (lots of smoke). I called 3D factory and he sent out a replacement board (the one on top). I have just hooked everything back up and still see a 77/0 or 78/0 for the bed temperature with nothing connected to it. I am reluctant to connect anything to T1 for fear that it will fry whatever is connected.
Does anyone have any suggestions?
