Laser cutter and carbon monoxide detector question

I recently acquired a laser cutter kit for the Shapeoko and have some concerns about the fume they emit. I have proper ventilation in my workshop and I’m currently planning out a fume extraction system for the laser cutter. In the meantime, cuts are being made in an enclosure and I’ve got a shop vac hose pointed right at the laser.

So my question is, do laser cutters emit carbon monoxide? If they do, I plan on buying a carbon monoxide detector. Are there any other detectors that you guys would recommend that I should buy?

Please be very careful with a laser cutter if you haven’t read up on the risks. Cutting certain materials (PVC, specifically) will generate lethal fumes. Proper fume venting is a must, no matter what you’re cutting. Not trying to get all safety-police on ya, but I’d put it in an enclosure and vent it to the outside of the building, at a minimum.


Here’s a pretty good list of things that shouldn’t be cut with a laser and things that are OK.

Things to NEVER cut with a laser!


By all means, please be the safety police. Safety never takes a holiday!

I actually have my enclosure sitting right next to my garage door. The door is even open during cutting. I’ll have to take a picture of my setup one of these days.

This is great, thanks for sharing!

But now that you’re here… tell me more of the laser module you’re using and the software driving it? :slight_smile: :slight_smile:
