and advanced Trinamic stepper drivers that could detect when the printer had slipped or gotten stuck. The optical filament sensor of the Prusa i3 MK3. But the most exciting upgrade of all was the ...

This post is about repurposing a commonly available inexpensive optical 3D printer filament sensor/detector module. This session starts with a quick introduction to filament sensors, as it might be ...

But, in this case, a 3D printed fan shroud uses an optical sensor to note when the Allen ... However, you can easily adapt the idea to your specific printer setup pretty easily.
