[support] pandaPI V2.5 - Sensorless homing
I cant make sensorless homing working with Pandapi v2.5, RaspberryPi4, TMC2209... could you share your working configuration.h and Configuration_adv.h file to compare? or update the doc, giving a troubleshooting procedure? thanks here are my files... Configuration.zip
you can try to change value of the sensitivity X_STALL_SENSITIVITY Y_STALL_SENSITIVITY, different motors may have different current and sensitivity.and do not forgot to unplug the endstops.
That's a good idea, bit still doesn't work... when I send M122, I see that TMC is disable and stealthChop is disable any other idea? thanks

The reason of this TMC Error message is that with write only access to TMC, and there is no RXD connection in the hardware. So that's normal.https://github.com/markniu/PandaPi/wiki/How-to-run-TMC2209-with-UART-mode-(V2.0-2.5) but still no idea why it does not work in your side!
