Hello All

I am currently setting up my 2nd reprap.
The printer homes perfectly with the switches at X min Y min and Z min but what I want is the X switch at X max.
So I move the switch and change X_HOME_DIR to 1 from -1, then try homing the printer, X axis now not homing am I missing something?

Thanks
George

Hello all

I just changed the X_HOME_DIR on my other printer which uses a Sanguinololu board, it homed perfectly in the + X direction.
So it must be something to do with Ramps, either the board or the code.

George.

What an idiot.
It works fine when the end stop is plugged into the correct socket.

Now to figure out why the axis isn't driving off the end stops.
