Hahahaha. Some people are so full of themselves...

Electronics Specs  - 
 
Hey, I was thinking about how one could make some "safety stop" when the print goes haywire while you're not watching it.

The most common thing that happens seems to be the model breaking loose from the bottom and then it flies off the plate and the printer makes spaghetti..

I thought about using a laserpointer and a wii camera for this.. The camera built into the wii can track up to four light points (normally IR leds) and can be used easily with an Arduino board (google arduino wii).

The idea would be using a laser pointer to put a light point on the very bottom of the print. As soon as the point can be recognized by the cam (the models first few layers have been printed) it checks if that light point moves in the x/z plane and if it does (it broke loose) it stops the print.

Its not 100% thought though yet but maybe somebody wants to chip in with some brain matter on this :)

you could do it that way, also the motion program on linux can detect changes in webcam images. If you just limited it to the base of the printed image, that might work too.

I imagine that most of you reading this are already aware of how much the cable monopolies are threatening #netneutrality , but for anyone who isn't, this clip from John Oliver lays out perfectly what's at stake, and why we're even talking about this right now.

3D Printer Information  - 
 
Mind those UFPs!
According to some late research the concentration of Nanoparticles in the air rises a lot around open 3D printers. See the german article here: http://www.golem.de/news/studie-schaden-3d-drucker-der-gesundheit-1307-100597.html

A short rundown for the non-german speakers: For PLA, about 20 Billion particles per Minute get released, while for ABS its even 200 Billion ppm. PLA is not regarded as being as toxic as ABS, which should not get into the body system anyway. Nano particles can get into the lungs and via the nose even into the brain and are said to cause Lung diseases, aneuyrisms and different forms of cancer.

So I suggest you keep your printing space well vented and especially keep it away from the children if you have any :) Generally I'd not worry too much about this, just be sensible and don't inhale printer fumes ;) I always was convinced the fear is creating more diseases than the actual dangers ;)

Just thought this might be interesting for us.

Cheers, Normen

Venting is a bit complicated for a simple hobbyist. build an enclosure around your 3d printer and when the printing process is over, just stick a vacuum machine in there bro. Even in asbestos sanitation we use vacuum machines and just schoop the stuff up.

Agreed.  Making a user also copy their info to make a copy is a powerful motivator for the normal user.

"Sure, you can copy this... just also copy these registry entries that include your name, e-mail address, and serial number... which by the way are all required because the serial is specific to your name+address."

"Uh, sorry dude... you will have to buy your own." :)
