Weird stepper issue when setting up Marlin printer When manually controlling the z-axis in reprap, it works fine. If I use the home button, it doesn't move. Instead, it stalls/freezes/hangs. It attempts to turn, but can't successfully make a full turn.
lower the moving speed of the Z-axis motor, search for 


  homing feed rate


in config.h as it looks like the given speed is to high.
