filament sensor EBB SB2209 CAN(RP2040)
Hi, can you help me please? I have no idea to which connector on the sb2209 board I can connect filament sesor which I have in the tool head Stealthburner.
Thank you so much
if your not using a proximity switch, try using gpio6 with jumper IND on and NPN jumper on. oh and don't use the V pin as that is 24v.. if you have a 3 pin switch.. normally you only have use 2 pins ground and sensing pin (gpio6).
Yes, Thank you

This is helpful info. Is there another spot that works? I have one before gears and after in my galileo 2 setup.

@Hulign nope thats the only "extra" port available to my knowledge.

I intend to use 2 pins on the probe connector (I use a cartographer3d scanner via CAN as bed probe). That way I think it must be possible…
Going to be installing a ERCF soon. Here is how I connected the two runout sensors.
@dearnheart nice... didn't realize SB2209 has 2 endstop ports.. (didn't really look at the schematics of the SB2209 thought they would be similar to SB2209-RP2040 version. Just different connectors and chip).. as I'm thinking of getting an ERCF v2 as well.. Now I have to think do I need to buy that version..

Give BTT horrible naming for these boards I can easily see the confusion.

Hi dearnheart, by the 'two runout sensors' are you referring to the Toolhead and Entry Sensor? Thanks!

Correct, I was planning on using this mod.

Great. I am at the road fork of deciding which route to go. Did you actually make the connections/test it working? or just planning phase! Thank you

Connection was made and fully functional.

Did this work? I’m looking to do the same.. cartographer via can on sb2209 (sb2040) 2 sensors on the probe connector. Thanks

Yes, all the details shared by @dearnheart are spot on and worked for me.
O no I was gonna do this too but sb2209 and sb2209 rp2040 are 2 different boards?? Is it not possible to put 2 sensors on sb2209 rp2040?

Wish I could say, I can only speak to the board I have.

i use BL Touch for bed leveling and i am able to use 2 sensors on the 2209 rpi2040. i used the spare GPIO (i think its GPIO6) and the extra fan on the cover plate using the PWM pin.
I've got gpio6 and gpio21 currently (on sb2209 rp2040 board). One of them is always showing detected and the other shows detected when I insert filament but then reverts to empty with filament still inserted. I'm not certain if one of the switches is stuck or not, but what would cause the detected state to revert with switch still triggered?

add a ! to the pin to reverse it "Pin names may be preceded by ! to indicate that a reverse polarity should be used (eg, trigger on low instead of high)."
Ya but that would just invert the state right? What's happening on one of my sensors is that I insert the filament, the state changes, and then without moving the filament, the state reverts to the previous state

Oh, sounds like maybe a bad sensor or something, I am at a loss on that one.
Ya I'm really confused... I've got a sticky top sensor (ball bearing not working properly) but when I take it apart and check with a multimeter both connections work. I have them wired NC. The bottom sensor on gpio6 doesn't change state in klipper. (The sensor that reliably works with the multimeter)
Could be the jumpers on the board, could be the switch is loose to the point it triggers when the filament enters but the pressure pushes it back, could be the wiring. To many variables

I have the same situation... already got a new sensor but the problem still exists... i wonder if there is a jumper missing? I will try the other GPIOs mentioned above, maybe they will work...

there is the jumper that sets the GPIO to fan or ind. it should be on ind
