    As per http://forums.reprap.org/read.php?1,163243 after uncommenting the CoreXY line in the firmware I also set the stepper to be enabled all the time (especially for Z in my case)

    // Disables axis when it's not being used.
    #define DISABLE_X false
    #define DISABLE_Y false
    #define DISABLE_Z false
    #define DISABLE_E false // For all extruders

    But if the Z is ok, the X and Y seems to be released and thus the movement of the H-bot style XY is not made correctly if the other stepper is disabled (in diagonal instead of straight in X per example).

    I was wondering if there is something on the hardware side that could explain that (as my other test board, an AzteegX1, didn't had this problem)

    I also tried to uncomment the
    //default stepper release if idle
    and all the other things linked, but it was worse ^^' (and it worked with it on the other board)

    Both firmwares are in my github repo for eventual comparison
