I checked the voltages across the current driver pots and all were 0.84v. I have the LSEE 3D V1 mainboard. I connected the Y-axis stepper to one of the sets of Z-axis pins and the y stepper began doing the same thing. Has to be something with the board. I also noticed that theres 5v and a 12v LEDs on the board... the 5v LED is lit.
