Laser Pipe Filament Runout Sensor

Laser Pipe Filament Runout Sensor

Provided as is:

This uses a small Laser to pass light through a transparent Bowden Tube Pipe to detect if the Filament has Runout or snapped.

No need to have any break in the Bowden Tube maybe good for flexible filaments.

I doubt if transparent filament will work with this.

There is a part for a small microswitch to be fitted to switch Laser off if the lid is opened for safety.

Create an Optical Filament RunOut that will not require a break in a Bowden Tube*, ideal for flexible filaments and easier to feed filament into, etc..

* For use with a clear Bowden Tube

Needs some more work to try to to make it easier to set up, has to be adjusted just right.

Could be made smaller, I have plugs inside that could be wired in directly saving space.
