For 1 you can use wget -R --mirror https://site.com (anyway man wget will get you there)

For 2 I'm unaware of a tool. Some combination of a browser, browser plugin and/or proxy would be able to do it theoretically, but there's so many JS edge cases it's unlikely to work everywhere. Something slightly custom may be required.

PS. With the laser engraving, fiber requires a cooling system which typically requires maintenance. Also, you generally require compressed dehydrated air at a minimum. Therefore, you're looking at a much more expensive system in aggregate.

Thanks for the information on laser systems, I haven’t used a fiber laser myself so that’s helpful.
