Unklicky Filament Runout Sensor 2

I have been using the Unklicky filament sensor on VoronMods, but it has been unreliable; the pin and roller wear out frequently.

This should last much longer. The two magnets on the left must be in the same orientation so that they repel. N52 grade magnets would be much better; however, N35 should also work.


Update 24/6/2024:

Soldering job gave up after a while, so I crimp JST XH 2.54 connector pins to wiring and use that for male connector joint.. see pics..
