Welcome, @LeeAnn!
Here’s a tutorial on how to setup a jig for a round lid, you might find it useful:
You may not need to make a support box, if your lids are thinner than 0.5" you can just setup your jig material (cardboard in this case) directly on your tray.
Then it’s just a matter of arranging your lids in your favorite SVG editor, and uploading the whole thing to cut your jig then engrave your lids.
It can be a little tricky, but it’s not that hard with a little practice. I’d suggest doing a test jig or two before you go in for the large multiple lid jig.
