Hi, just connected a btt filament sensor to my Vcore3. No matter which connection point I use on the main board I can't get it to work. Does anyone know how to get it working?
The main board is a skr pro .
Points tried, E0,E1,E2, T3 .

I'll have to get back to you on Monday, I've just finished for the weekend sorry

I did have some trouble too with that sensor on my SKR Pro 1.2, my solution was to split voltage and ground (to endstop connector) and then the signal wire to the LCD EXP-2 whatever signal pin.

what error?
The error is "Pin E0 is not a valid pin name on mcu"
But the instructions I have found online say to use pin connection point E0
Or do I need to use the specific signal pin?
- Set the pin ID to the signal pin on E0, it seems to be working for now

if you use ratos you dont need to set any pins, you jsut need to conenct it like yiu ccan see it in the ratos docu
also i dont think the skr has a pin name E0
should be three characters

Looking at the schematic, it's pin pe15 for the signal in connection point E0

E0 is the connector name, the group of 3 pins
PE15, PE10, ....
these are pins

Got a bit confused, thanks
Fingers crossed the next test print goes better than the first one, forgot to plug the sensor in🤦♂️

As i pointed earlier mine did not want to work using connector E0 and pin !PE15 had to split wires and leave ground and voltage on connector E0 and use the EXP-2 signal pin connector to make it work. It now works fine, I guess there might be some interference or something. Remember you will most likely have to use ! Before pin number.

Tbh it just doesn't make sense as to why E0 isn't used for this, like btt says it should be.

That's because on the SKR Pro 1.2 you have to cut the corresponding stepper driver's DIAG pin to use the endstop pins. The DIAG pins on the stepper drivers take precedence over whatever you connect to the endstop ports. This is one of the reasons most of us prefer the more modern boards where you can just remove or place a jumper to control whether the DIAG pin is connected or not.

Thanks for the explanation 👍 You could have told me when I installed mine though, I went through a nightmare to make it run properly...just kidding !!! 😉

Which pin on exp-2 is the signal or does it not matter?
Technically it doesn't matter, I chose the one on the pic.
