While 3D printers are an exciting technology, in many cases people leave them alone to work on their projects for hours at a time. As is the case with any kind of machinery, there’s an inherent risk of malfunction or fires. However small, it’s important to have something in place to shut down the printer.
3Dsmoke is designed for 3D printers using filament deposition, which involves electricity, high temperatures, and flammable elements. The device cuts off power to your printer when a wireless smoke detector senses the presence of smoke or a fire.
The kit includes a wirelessly controlled power outlet and a small wireless smoke detector to ensure an added layer of safety in your workspace. The 3Dsmoke can safely run and switch off printers up to 2500W. All you need are 2 AAA batteries to power it, and the expected lifetime for those is an entire year.

  •    3Dsmoke is designed to safely run and switch printers up to 2500W;
  •     you can mount this smoke sensor anywhere as it's wireless;
  •     the 2 AAA battery can last one years;
  •     small size,high sensitivity,optical sensor;
  •     this is more robust by cutting off the power source on a separate system;
  •     include a wireless controllable power socket and a tiny wireless smoke detector;
  •     Overheating protection

I sell on Tindie

Connector: underrated connectors on the boards,and use inadequate torque when tightening terminals,as the wire works itself loose,it starts arcing and burning the connector.

Failure of the MOSFET.
     most the printer use the MOSFETs to switch power to the heating lement.unfortunately,when MOSFETs fail,they usually fail close(i.e. conducting).this means that,even if the firmware detects 
something has gone wrong,it won't be able to do anything about it.

how to pair wireless between power socket and smocke detector? (had paired by default)
1,power on the power socket and smocke detector;
2, Press and hold the Power socket's button until the LED flashes;
3, click the button on the smock detector;
4, and then the LED on the Power socket will flash quickly,means it's paired successfully.

 is it possible to use several detectors( or Print Complete Auto-Close Modules) with one plug? yes,one socket can be turned off by at least 8 remote controllers at the same time. BTW the remote controller have unique
encode ID,so the remote controller need to bind the socket.

Hi Mark,

I bought your 3D printer smoke detector from Tindie. Great idea!

I was wondering if the power socket be controlled from a phone?

  Are you sure? yes | no

Thank your so much! this socket use the wireless chip just like the car fob,so it can not be controlled from phone.

  Are you sure? yes | no

Hi, would you be willing to share the schematics/source files?

  Are you sure? yes | no

mark wrote 11/02/2019 at 02:00 point

all the source are here,https://www.thingiverse.com/thing:3698790, sorry for no schematics. you can find many those schematics on google.

  Are you sure? yes | no

thanks @Martin  for the question,this power socket has isolated power supply and self-recovering fuse. 

  Are you sure? yes | no

I like this idea but i think a wired solution would be better. Radio transmitters or receivers fail, often....

  Are you sure? yes | no

mark wrote 06/26/2019 at 00:46 point

Thank you very much! the other simple way like you said is to remove the radio module and wiring the signal/gnd directly. 

  Are you sure? yes | no

Martin wrote 08/05/2019 at 14:47 point

I also prefer a wired solution for a safety device. It's just more reliable.

But I want to emphasize to be careful: Most wireless sockets do not have an isolated internal supply. Often only a capacitive dropper. So it's important to know what you are doing. The construction and isolation of the smoke detector is normally not designed for direct mains connection.

  Are you sure? yes | no

I like your project, it definitely has an important application with 3D printers.  I've heard of a few catching fire.

Do you intend to do any testing on a printer?  eg. Shorting a hotend to see how your detector will respond?

  Are you sure? yes | no

mark wrote 05/29/2019 at 03:22 point

Thank you very much for liking and the good recommends!I will do more testing and make it more suitable for 3D printer,eg.adjust the sensor sensitive,smaller for easy mount.

  Are you sure? yes | no
