Here

// Invert the stepper direction. Change (or reverse the motor connector) if an axis goes the wrong way.
#define INVERT_X_DIR false
#define INVERT_Y_DIR false
#define INVERT_Z_DIR true

My issue is that the AXIS are moving in the right direction. When moving in S3D. But when I try to home its backwards. Should home to the MINs. XY is Moving in the MAX direction for about 5mm

Sorry wrong lines
// Direction of endstops when homing; 1=MAX, -1=MIN
// :[-1,1]
#define X_HOME_DIR -1
#define Y_HOME_DIR -1
#define Z_HOME_DIR -1

I get the following error.

#error "Enable USE_XMAX_PLUG when homing X to MAX."
I don't have endstops pluged into XMAX or YMAX

I'm trying to home my XY to the XMIN & YMIN
