Hello  
My Mini has decided to stop autoleveling. When the Autolevel sequence begins it goes to the first corner and instead of starting down it retracts the Z axis and goes to the second corner retracts again then the third corner and fourth corner as well. Then with the nozzle about 50mm over the bed it begins to print in thin air. I suspect there is a short somewhere which tells the leveling system that the nozzle is in contact with the washer when it is not. I have heard that there are several issues tht can cause this to occur. Where can I find a wiring diagram and connector pinout ? How can I tell whether the main board has been damaged by heater current to the Z limit?
