Hm that’s seems to be pretty hard to do.
Why would you like to take out the egg and then put it into the eggbot again? Why not do all the marking at once?
my spontaneous ideas:
two sticks in V-shape above and below the egg to center the egg while rotating the egg axle
mounting a non-marking pen doing a “dummy marking”
mounting a laserpen with a real small light-point starting a dummy-marking of adjustable length (number of lines) watching the deviation and then correct egg or arm-position
repeat this until dummy-marking fits sufficient to existing marking
