If this was indeed a LASER cutter then you would definitely be able to smell all the other gases emitted with the CO. I've got a small LASER cutter and even with the hose going outside the smell very strong.

One post up above says some of the newer cutters targeted at consumers have carbon filters and exhaust the air directly back into the room. The carbon doesn't capture CO but may capture the odors from other compounds.

So, a bad design that sells well, but hides the important signal.

In case of natural gas, we have long long time ago started mandating odorization (after a lot of silent deaths): https://en.wikipedia.org/wiki/Odorizer

This time, we basically allow laser cutter manufacturers to ignore these lessons (learned with a losses of thousands of lives).

Well we don't know for sure that that was the cause yet.
