The SD cards read just fine and the files in the SD cards open just fine. The 3D printer was in storage for a little over a year because I didn’t have the room in my apt for it. Now I am in a bigger apt and I have the room for it. The 3D printer starts up, the bed starts heating up and the nolise heat’s up also . But I keep getting the following errior message of “SD init fail”. What gives with the 3D printer???
