If the dual head is in the middle of the bed, when I select auto-home, the Y axis will move the head to home, Z axis will simultaneously move up and the auto-level sensor will see it and then the bed goes to 4mm (as I expect it would). BUT the Rumba thinks the X-axis is where ever the head is during power up! IF i move the head all the way to the left, select auto-home, then the head correctly auto-homes, albeit the home goes to 5,5,4mm. (x,y,z) Shouldn't the X axis ALSO move to home no matter where it is ?
