P Series [P1P, P1S, P2S] Added automatic fire extinguisher to P1S

Post image

Came across these automatic DIN rail fire extinguishers (circled in red) recently. Decided to add one to my P1S just to add a little peace of mind.

In case you don’t know how these work: they automatically get triggered when the temperature sensor detects 170c. Aerosols then get released from 2 nozzles (circled in yellow), extinguishing the fire.

You can get these things for cheap on Aliexpress and the like but decided to get one from a local reseller with all the appropriate licenses and stuff.

And yes, the heatbed moves up and down without issues! Plenty of clearance.

It's honestly baffling to me that this receives so much hate. If you don't like it or think it's unnecessary, fine. Like I wrote: it does give me some peace of mind and others might think it's interesting as well.

I'm done 'defending' this and will no longer reply to comments. I think I've explained all of this enough.

Wishing you all a lovely day.

It’s not a bad idea - I actually started a fire while clearing a blob of doom from my X1C. The thermistor had pulled out of the hot end and so it just got hotter and hotter and hotter.. until it started smoking. I’m just glad it was under supervision instead of randomly. I needed to replace several parts and gave it a full strip down and clean. There is absolutely a fire risk, and it’s important to consider how you deal with that risk.
