Sunhokey Filament out sensor.

Got 2 of these for my printers, Cartisian on Maestro and CoreXY on Duet2

They have just been delivered and was expecting a wiring diagram to come with them but alas not!

Has anyone installed one of these who could shed some light on the wiring.
At a guess, it would only need 2 wires out of the 4, connected to an endstop input, possibly?

Regards,
Paul.

@PaulHew Most of the ones I've seen on Amazon are three-wire eg https://www.amazon.co.uk/Sunhokey-Printer-Filament-Detection-Detecting/dp/B07JJ2835X
Is yours different? Nothing on Sunhokey's website either, as far as I can see: https://sunhokey.cn/collections/printer-parts

There's this thread, but doesn't talk about wiring much: https://forum.duet3d.com/topic/12391/run-out-sensor

Otherwise, I'd guess it was a simple microswitch. You may have to take it apart to check how it's wired up. Then see https://duet3d.dozuki.com/Wiki/Connecting_and_configuring_filament-out_sensors

Hi Ian

Looking at it with my glasses on, there are 3 wires!
I think you will be right, simple micro switch.

I will pin it out later.

I thought there was more to it.

Thanks again

Paul
