Anyone know if the fumes and/or heat from an enclosed printer would set off a standard smoke detector mounted within the enclosure?
Might as well give it a go, worst that can happen is some really loud noises.

No. But one time I had a small piece of abs stuck on the end of the heater cartridge and that did set off the smoke detector. I couldn’t really see the smoke, but it smelled like burning plastic just before the alarm went off. I have smoke detectors above all my printers with a fire extinguisher near by.
@Evan_Nguyen that’s what I’m going for as well. Picking up a fire extinguisher next week and installing this smoke detector so I can start doing overnight prints
Smoke detectors only sense particulates larger than anything a properly-functioning printer will emit. So, smoke, not fumes.
There are 2 types of smoke detectors, ionization and optical. Optical likely wouldn’t pick up the fumes while ionization might.
I know that ABS from an not-enclosed printer has set off a detector for me. Quite reliably. I’m fairly sure it was ionization-type. Haven’t tried it since I got the big air filter.
That is some hardcore safety.
@Chapman_Baetzel I would rather have it and not need it then need it and not have it. Plus it’s the only way my wife will let me start doing overnight prints 
Oh yeah, good point on ionization detectors. Pretty much every fire regulatory body in the world recommends using optical detectors and NOT ionization detectors now. So if you can change them out, you probably should.
I think it would be better if they used carbon dioxide and oxygen sensors.
There are also monoxide sensors. But you can’t just go with combustion products as a warning sign unless you’re will to have lots of false alarms. People have furnaces, stoves, candles…
Just to update this thread. I’ve printed with PLA and ABS with the detector in the enclosure (both open and sealed) and ran into no issues with false alarms.
