I'm almost there. I've just configured my board (RAMBo 1.2) and it's working well.
One problem I have is I can't figure out how to set the "Home" position.
All the motors respond to manual commands except 'Home"
If I manually put the bed and hotend where I want them, then turn on unit and load Repetier it says that all axis' are at "0" ..if I move 50 mm for instance to the right (X) and then hit X home it moves about 5 mm and says that this is now "0" location...each time I hit home X it does the same thing. The Y axis does the exact thing....The Z axis moves 5 mm approx ...Up instead of back down to where (0) used to be. I know it's just a couple of adjustment in the Configuration. H but I have no Idea how to do it.
Any help would be appreciated.
Thanks again.

Sounds like your endstops are not wired properly or are all triggered. Sending an M119 will reveal everything.....
