Then say something like "means things like the Glowforge", instead of "probably means a Glowforge". One denotes membership in a certain class, providing an example.

The other unambiguously suggests the example is the culprit. And as other posts in other threads suggest, the printer, whichever brand, being the source of the CO poisoning isn't even certain.

I don't work for Glowforge, and you may note my other comment in this thread, which could be taken as critical, so I'm not biased or trying to spin "damage control". And yet, I too think the thread's root's language could be more precise.
