We used the RA2 to engrave a raw egg for Easter. Please note. To get the eggs properly secured, I printed and used an adapter. I got this adapter from Hardy with the link here. https://www.designfind.com/project/7429-engraved-easter-eggs All credits, regarding this adapter, are for this designer.
It's very easy.

Clamp the egg, between the adapter and the original Ra2 pro end clamp.
Align the RA2 pro with the laser of the F1 ultra.
And give the F1 Ultra the command to start its task.
Note: Place the RA on a container or lid, so that (if the egg shell breaks) it is neatly caught and does not run into the machine.
I was able to boil the eggs at a later time, without them breaking during cooking.
