Hey everyone,
Recently purchased Ramps 1.4 and after a slow start finally have it responding. the x and y axis are smooth as silk and move back and forth but the z axis doesn't do anything. When I hook up the Z axis motor to X or Y or the board it works but slower and for a shorter distance but at least it works. However, the motor i connect to the Z axis port just buzzes. On my old Gen 3 electronics I could adjust the pots and usually correct this. any ideas ?
thanks
