On “reusable”, what I do is cut my jigs so they nest into the lower-right corner of the machine, but large enough that the target(s) will be near the center.
So I have several that I have used over and over, I just pop them in, open the file for that material (pens, pencils, dog-tags, business cards, gift tags, etc.) and import whatever needs to be engraved, then print.
I have done similar with snapmarks but jigs are just so simple and quick, I rarely bother with snaps.
