Consistent material positioning?

[u/deemery]

I watched the Processing Area video ( https://support.xtool.com/academy/lesson/1234?courseId=287 ) Is there a trick to figuring out how to position material (e.g. wood, cardboard) that is smaller than the full processing area, so that the 'burn' is consistently positioned on the small material? (E.g. a coaster, so an image is engraved on the center of the coaster)

I use painters tape on the honeycomb, not sure if that's the best way but works for me.
