Just out of curiosity why do you want to do that?

Thanks.

Yes it's possible, but why?

Assuming you're on V3.2b you can use the random(nn) function
Check release notes for which version it was introduced in.

E.g

G1 X{move.axes[0].max/2 - 25 + random(50)}

Would put you +/- 25mm from bed centre assuming X max defines the edge of the bed and X min = 0
You could always hard code it.

Reasons I've seen given for requesting this in the past has been when using nozzle contact probes a small divot can develop after repeated probings in the same place.

makes sense!

The reason is exaclty as Phaerdrux explained. I am using a piezo on the nozzle to home my Z axis.
Thanks for the quick answers guys
