Hello, dear Makers and 3D Printing Enthusiasts!
This is a Optical Filament RunOut Sensor.
The working priciple is the same as the one from Mini Dual Drive Extruder PLUS and Mini Dual Drive Extruder BOWDEN
The ‘’ Key Features’’ of this design:
•Simple and compact design
•Reliable (there is no mechanichal switch)
•The color an texture of the filament won't affect the sensor functioning
•Easy to install on any printer
•The filament can be fed from both sides, the sensor works the same
Staff needed in order to build it:
1) Pneumatic Connectors:
2) DIN912 Screws:
3) Optical sensor:
5) Neodym magnets 8x2mm:

- two M3 DIN912 Screws are needed: one 10mm and the other 35mm or longer
- by adding a M3 T-Nut, it fits perfectly on Alu-profiles (see the pictures)
- putting the sensor together, goes something like this:
Function test of the Sensor:
Updates and improvements may come and I will keep track of them here:
1 - 04/05/2020 - First Release of the project on MyMiniFactory
* only the files corresponding to the last state of development will be published. If of any reason you may need an older version, simply write me an email at email@example.com
*** the pictures from reality may show an older development state
You don't have to, but any donation would be very appreciated.
