homing of gantry with servos using index

I have a gantry router with servos. 2 motors on the y axis. The index on each motor are .692" off from one another. I am trying to home the gantry using these parameters:[AXIS_Y]
MAX_VELOCITY = 1200.0
MAX_ACCELERATION = 2.0
MIN_LIMIT = -0.05
MAX_LIMIT = 96.0

[JOINT_1]
TYPE = LINEAR
HOME = 0.0
FERROR = 0.9
MIN_FERROR = 0.5
MAX_VELOCITY = 1200.0
MAX_ACCELERATION = 2.0
P = 50
I = 0
D = 0
FF0 = 0
FF1 = 0
FF2 = 0
BIAS = 0
DEADBAND = 0
MAX_OUTPUT = 0
ENCODER_SCALE = -196000
OUTPUT_SCALE = 10
OUTPUT_MIN_LIMIT = -10
OUTPUT_MAX_LIMIT = 10
MIN_LIMIT = -0.05
MAX_LIMIT = 96.0
HOME_OFFSET = 0.692
HOME_SEARCH_VEL = -.05
HOME_LATCH_VEL = .01
HOME_FINAL_VEL = .01
HOME_USE_INDEX = YES
HOME_SEQUENCE = -2

[JOINT_2]
TYPE = LINEAR
HOME = 0.0
FERROR = 0.9
MIN_FERROR = 0.5
MAX_VELOCITY = 1200.0
MAX_ACCELERATION = 2.0
P = 50
I = 0
D = 0
FF0 = 0
FF1 = 1
FF2 = 0
BIAS = 0
DEADBAND = 0
MAX_OUTPUT = 0
ENCODER_SCALE = 196000
OUTPUT_SCALE = -10
OUTPUT_MIN_LIMIT = -10
OUTPUT_MAX_LIMIT = 10
MIN_LIMIT = -0.05
MAX_LIMIT = 96.0
HOME_OFFSET = 0
HOME_SEARCH_VEL = -.05
HOME_LATCH_VEL = .01
HOME_FINAL_VEL = .01
HOME_USE_INDEX = yes
HOME_SEQUENCE = -2

Basically what happens is the joint 1 motor reaches index first and then stops. the joint 2 motor continues to search for the index and causes the gantry to rack. How do i keep the joint 1 motor going after it reaches the index for .692" until the joint 2 motor reaches the index? I'd rather not ignore the index.

just to note, the gantry is very rigid and will not allow more than .005" of misalignment before it binds the motors.

I would think its necessary to align the index's of the 2 gantry
that is, I would expect the .692" of offset  to need to be reflected in the limit switch
positions as well which seems iffy at best

yea i took the motor off the machine and rotated it and got it close enough to home, then did a home offset on one joint to make up the few thousandths it was off. seems to be fine now, thanks.
