BTT EBB sb2209 RP2040 and Klicky Probe


Recommended Posts

Hi can you please help me configuring Klicky probe on this board?

I tried using the probe port and (GND and !EBBCan:gpio21) but it doesn't result open once the probe is attached nor change state when clicked.

Is it possible to have the schematics of this board?

Thanks in advance

I had exactly the same problem and finally found the solution on the Voron Discord.  Apparently it's not possible to use gpio21 as it connects to some other component before the mcu.  Use gpio22 with a pullup symbol instead.  Like this in your Klippy config:  ^EBBCan:gpio22
