I finally got my BigBox-1.0Dual connected via USB to RepetierHost. Even after running auto-home on the BigBox, leveling the bed etc, when I start a print with RepetierHost, it thinks z is at home = 0. BUT in actuality, the bed is about ~2mm below the nozzle, and obviously nothing can print in thin air. AT least not yet. How and WHERE do I make the adjustments? Remember, all prints fine from the SD card.
