Hi all!
I'm building myself a custom Reprappro Mendel, but are having troubles getting z home to work.
When I send G28 Z (home z axis) the z-axis moves ca 1 cm in the wrong direction at the fast home feedrate speed. It behaves as if I sent it G1 Z10, just slower. No bounce back. Tested with different versions of Marlin, same result.
Sending M119 gives me "z_min:H" no matter how what I do with the endstop swich terminals (like shorting, unplugging or trying different swich). I've looked for shorts on the Melzi board without any luck. X and Y homing works as expected...

Any suggestions?
