X and Y moving wrong way

Hello,

I just finished building my Mendel and have a problem with the axes.
Z axis is fine but when I 'Home' X or Y they move in the opposite direction of the endstop causing it to crash.

I suspect a software problem but don't see any options in the reprap host software to inverse the X and Y movement.

I'm using the 5D firmware and gen 3 electronics.

Thanks,
Diego

Hi Diego,

... you can reverse the pins of one stepper-coil to invert the driving direction ...

Thanks,

I suspected that something like that would be possible.
But I'd like to keep that for when there's really no other possibility.
I'm using stepper motors from makerbot and left the connector on the way the supplied it, I also left the connector on the Stepper driver board so it was just plug and play.
Is there really no other solution?

I think the firmware has a direction invert flag somewhere in the machine definition header
