OK, it's good to know it wasn't yours. Thanks.

It would be appropriate to put a CO detector in your units before somebody does that with one of yours. That definitely needs to be in the "filtered" units that are supposed to operate with no ventilation.

Might be worth editing your original comment to remove the suggestion that it's a Glowforge, just to avoid unnecessarily associating a specific company that wasn't involved in this tragedy.
