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.
