3D Printer – Filament – Runout sensor (mechanisch)
Deze sensoren kan je aansluiten op bijvoorbeeld een RAMPS v1.4 board op D2, en met de nieuwste MARLIN firmware in te programmeren!
Microswitch filament runout sensor (voor 1.75mm en 3mm)
Thingiverse commentaar:
Here is a simple filament runout sensor. I was going to use an optical sensor, but I print using clear filament sometimes, and wasn’t sure how it would work. In any case I had several of these microswitches laying around and decided to use them. These have a flag, but no roller. Note that I slightly bent down the end of the flag, so that the filament would slide either way, but you want the primary direction to be so that it goes with the flag. I put a mark on the outside of the assembly so I would know which way to the filament goes. To secure the two haves, you need 3x M2x12mm bolts and nuts. I created versions for 3mm and 1.75mm filament. It will clamp onto entry or exit tubing. I assumed 6mm tubing for 3mm filament and 4mm tubing for 1.75mm filament.
Notes:
Nothing special required. Miles and miles of filament passing thru could eventually grind down the channel, so I guess tougher is better. I used HIPS.

Thingiverse commentaar:
Runout sensor mount, you will need three 2mm screw and bolt.
