    Hey Mariano! Great guide! I've got my motors set up and your version of the marlin firmware uploaded, with my measurements in place, and the motors running in repetier, though when i use the manual control function i only get an upward z response from all three motors when trying to alter either the x or y axis and no down control response, any ideas why this may be?
