I suspected the direction pin based on the behaviour and swapped in the extruder driver which magically fixed the problem.
I did have the endstops wired to the min inputs because thats what the configuration on the Repetier tool had at first. I switched them to max and re-did the config and now I can how with G28 just fine. I'm working through the steps in the article you referenced in your blog post to set the X, Y, Z towers and then the plate center.
Not a bad Sunday, setup the whole firmware toolchain, compiled and downloaded firmware, got extruder and bed heaters going, got X, Y, Z all moving correctly and roughed in endstops.
My X, Y, Z are still a bit high and I have not even started to tweak the center. About now is when I would appreciate the adjustment screw I've seen on other carriages. I'm stuck moving the endstops on the openrail which is frustratingly tedious but I'm getting there.
