I'm a little confused here... Homing moves the X and Y axes to 0,0 first. The Z axis IR endstop on the dual hybrid titan head is on the left (i.e. beyond X0). That means that when it starts homing the bed (Z-axis), the IR endstop can't see it, because it's parked above the upper support of the case, well away from the actual bed surface. How is this supposed to work? What am i missing here? Did someone forget to enable #define Z_SAFE_HOMING in the marlin configuration?
