Following the xtool guidance on setup works for S1 with the original baseplate but doesn't work quite the same way if you are using a honeycomb plate and have the riser base installed. A few tweaks get's this up and running so you can use the Snapshot Preview feature with XCS 2.x! Idea: engrave the stickers onto wood or acrylic and glue onto a magnetic post to allow snap into the honeycomb like the hold-down clips.

Download and print with an Avery 8163 (or similar) label sheet loaded. (Or just use paper with some glue. I recommend rubber cement.)
With the riser base, put the base plate into the highest slow and insert the honeycomb on top. I usually position my honeycomb to be flush with the back and right sides of the machine to keep it somewhat square and repeatable.
It isn't immediately obvious, where to find this option. On the app…
Using the laser guides, I positioned the laser head at the extreme range on each of the 4 corners and then affixed the 1,2,3,4 stickers (hint only #4 is different) by aligning them on the inside quadrant to ensure that they would be available for calibrating in later steps.
Position the laser pointer above one of the stickers. Then hit Next.The S1 will attempt to detect the height.
This part is really as directed in the app and tutorial. Position the laser head over each one of the stickers in the following order 1) top-left, 2) top-right, 3) lower-left, 4) lower-right. Put the crosshair centered on the dot in the middle of each sticker.
The next screen will ask for the overhead shot with the 4 stickers positioned within the frame. Click the green checkmark button to proceed.
Note: It isn't entirely clear that this step is necessary.
Setup your items on the honeycomb. In this case, I am using a jig to hold 6 metal business cards for engraving.
Smart Fill worked fairly well but tends to flip the last image upside down at the time I am writing this. I suspect this is a bug that will get fixed. No biggie. Just flip it or delete it for now.
