McWire Z-Axis Stepper Directions

Maybe I'm just being dense here but can anybody tell me how to get my z-axis to drive DOWN to the home position instead of UP? Everything on my machine is finished but I can't seem to find any preference settings for saying that my z-axis goes down to the print surface and not that my print surface goes up to the print head. Ideas?

Hi Demented,

... when you didn't find a software-aproach, then you can reconnect the stepper-wires, so it would turn the other way, or simply invert the DIR-pin ...

its much easier: simply plug in the stepper connection 'backwards'

however, i think we should update the software so that it homes at the top. otherwise you have to precisely align the physical stuff so that it works instead of stepping a certain number.
