Describe your issue:
I have reached the end of my knowledge and I am now hoping that someone here is smarter than I am.
I am attempting to configure sensorless homing, but am having exactly zero luck doing so.
The behavior is: I issue G28 X0, my toolhead never stops. It rams the frame and stalls, making a terrible noise.
As far as I can tell, my config is correct. I have quadruple checked the pin naming, run through the setup in the Klipper documentation, found an example from Voron that matches my exact setup to no avail, etc.
I soldered the diag pin onto the 5160 myself, the joint is good. The pin is the same length as the pins that came factory soldered, so it shouldn’t be a contact issue. I know with 100% confidence that it’s in diag1. They’re BTT steppers and I followed their pinout.
The steppers function correctly outside of this. They’re correctly jumped for SPI. Stallguard is also correctly jumped on the board. USB power is disabled per BTT documentation.
I am genuinely at a loss. If anybody has ideas I am willing to try just about anything, even if I think I’ve tried it before.
Thanks in advance!
