Describe your issue:

No issue using the board flashed with Klipper via serial. Wanting to add additional runout sensors on pin 27 and 29 if possible. I only know how to define the pins in Marlin using the native names/aliases. Does anyone know how to define these in Klipper? Sorry I am new to all this coming from the Marlin world…

Thank you in advance!

As shown in the posted link: Define any number of sensors similar to the one you already have, but with a different name.

Sorry, I think my question was written poorly. What I am looking for is the pin 27 and 29 identification to define it as a sensor. Like where the endstop for X is PC2 and Y is PC3. Do 27 and 29 have such an identification to use in Klipper? I could be missing something; sleep has not been kind to me the last few weeks :frowning:

I’m not sure that I can meaningfully support this, as the available information on this board is pretty scarce.

If you are referring to the ATmega1284P pin numbering, here are the corresponding pin designations as used in Klipper:

  • 27 → PA3
  • 29 → PA5

I didn’t think to look at a ATmega breakout, is that what you used? :frowning:
