What parts of my ramps board are fried?
I accidentally touched a screwdriver to my extruder steper driver and right away it smelled like something fried, and the (2004) display went white.
I replaced the driver, and adjusted the contrast screw on the back of the display. The printer seamed fine until I started a print than it just want nuts going to all sides of the bed and up and down.
EDIT: I just tried to move the axis manually with the LCD and it worked but gcode from the sdcard homes and then just goes al over the place.
