CR-10 Smart Homing, Z stops moving down after 20 or 30 MM

  • If the Z height is more than about 30 mm or so, the nozzle will move down only 2 or 3cm and stop, cannot move Z down any more than this using menu. It will move up, using controls and back down again to same place it stopped before and will not go lower.

    If I turn off power and use the Z rod to move Z height up, it will still only move down 3 or 4CM and stop at the new height when power on again.

    Auto level seems not affected and will move down and work from any height, it is only homing X/Y or homing Z from Prepare menu this problem occurs.
