3D News: DIY Filament Clog Detector #3dthursday

Aaron Tunell shares his clog Detector:

Detects any type of loss of filament movement due to:
1) Out of Filament
2) Filament Jam
3) Extruder Clog

Activates Sailfish P-Stop by dropping PJ2 voltage to near zero after several seconds of nonmotion.

Aaron mentions based on the Gen5 Smart extruder teardowns he did, it looks like they are using a hall-effect based encoder for the same task. Arron’s is just a 24PPR mechanical encoder!

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
