How to move Z to below zero

How do I configure the Repetier firmware to let me manually move the Z axis to positions below zero? Trying to touch-off the nozzle to the print bed for zeroing and leveling. It currently stops movement at Z=0.0, although the nozzle is above the bed.

    to disable target coordinate check. If you have a z min endstop and do check for endstops it will not allow to go past the endstop.

    LCD menu has in calibration a z move that also ignores z=0 boundary.

  • Thanks, I've been pounding my forehead flat trying to figure this out.
