Hi JAZZCNC

Thanks a lot for your reply.

Could you please explain? How did you figure that out? is it form the pictures that I provided? Please explain

what is the fix for that problem?

I figured it out because you only have 3 Motor axis enabled. The fix is easy you need to connect one of the drives to another Motor Output and then use Slaved axis.

I see your post about different Home switches but still the way you are running the machine from one Motor Output isn't correct and will cause you troubles at some point. The problem comes from pulse timing and over long jobs then any latency in timing will have an affect on position.
The only exception to this is if the Servo drives provide a slaving option. In this case, you will have the slaved drive connected to the master drive via a cable so will be easy to tell.

Also the way you have it setup now then your only homing to one Switch on one side. If there is any error between the motors/screws it will never be corrected and over time this will twist and rack your gantry.
If you had it setup to use slaved axis then you could home each side to it's own switch and be sure the gantry is square. Also because your using servos you could use the Index pulse of the encoders to ensure accurate homing of each motor.
