I believe I've followed the instructions. I carefully did the wiring having had some negative experiences. At this point all but one thing is working. The one thing is maddening though.
For Marlin I'm using the latest stable off of Github. I've made what seemed like appropriate changes to match the reprapguru i3 I have. What isn't working is that the X control in the manual controls in repetier move the Z axis and not the X axis. This seems impossible. The wiring for the X is straightforward. The Z steppers are wired in parallel and plugged in. I'm at a loss - I couldn't find and can't imagine a configuration for something like this.
Any help would be gratefully received.
