Will it work with the ZRIB or Melzi Board?

It will work with any board that has an extra input pin available, and firmware that has a filament runout detection.

Hello,
What is the principle of the optical sensor applied?
Does the optical sensor work on transparent and translucent filaments?
Thanks, Vojtech

Hi Vojtech,
It is a optocoupler, and yes it detects translucent filaments, that is why we put this picture on here :)
As you can see the top entry has no filament going into it (red light is on) and the bottom entry has completely clear filament go in it.
You can not use a slotted optocoupler as the translucent filaments actually magnifies the light.
