Anyone know what kind of inductive probe comes with a simple metal and how to connect it to a ramps 1.4? I tried to search online but everyone seemed to do it slightly differently and it would be a shame if I did it the wrong way and saw the magic black smoke. Thanks

It’s an NPN type like this:

The reason people blow these up is because they don’t use a voltage divider which is necessary when not using a Printrboard. Tom has a great video on the proper setup for that on youtube. Aside from that it’s pretty simple. Just be weary as the colors of the wires do not file a logical polarity (I think black is signal and brown is GND with these sometimes. https://www.amazon.com/uxcell-DC6-36V-Inductive-Proximity-LJ12A3-4-Z-BX/dp/B008DG9FLS/ref=pd_aw_lpo_60_bs_img_1?_encoding=UTF8&psc=1&refRID=JB1VEZWS26RY6NDB54Y2

I was going to mark it as spam till I realised the joke :joy:

Hmm it’s made by Lucas so perhaps I should try it in my Triumph…

@Griffin_Paquette it’s worse, black is signal, blue is GND, Brown is V+.

Ok so something odd happened. I wired it up and with 2 10k resistors the output was 6.8v. So I tried 1 4.7k + 2 10k’s and now it wont fire up anymore, every time I try to power the sensor the light wont come on like usual. these things can take 6-36v so how on earth did I burn it with 12v? unless Im missing something else
