Filament pause switch

Anyone have Ideas on how to make one?

I’m using half rolls and I’m afraid to run out during a print.

Open up your configuration.h and do a search for filament, it’s in there. Add one of these and some wires and it should work, if you print from the lcd! I think it’s servo3 pin. Not sure if this works, but that’s what I found.

I’ve made these for my printers. They all run repetier fw though.
