G28 only Homes Z axis

G28 only homes the z axis, doesn't even try for x and y. It is set to do x, y, then z per my firmware config. None of the endstops are tripped, and I have verified proper functionality with M119 to ensure they're High and Low as expected. It's almost like both the x and y axis are triggered by default, but they both come back with low on an M119... any thoughts as to what might be the issue here?

    I should also add that I can jog x and y in one direction only and back to "home" (being where they started when the machine powered up) and all endstops still remain un-triggered (low). However, hitting home-all or sending a G28 only homes the Z axis.

    Sounds like homing direction and end stop type might mismatch. 
    E.g. if you have homing to min endstop direction = -1 and only a max endstop it will not home. Otherwise if M119 shows low before homing it should move towards the homing direction.

    You were exactly correct, changing around my endstops / directions ended up fixing this problem. Thank you!
