Hey, welcome to the forum! We love new people around here.
As for your silicone question, there have been a lot of silicone posts over the years, the search box in the upper right lets you go digging through the archive:
https://community.glowforge.com/search?q=silicone%20engrave
Tons of ideas, tips, and inspiration here.
You can refine the search a bit too, see if anyone posted settings. This is looking for “silicone engrave settings” but only in the first post in a thread, not in the replies:
https://community.glowforge.com/search?q=silicone%20engrave%20settings%20in%3Afirst
That kind of filter can really help improve your search results.
