The `homing_retract_dist` setting should be set to zero to disable the second homing move as a second pass is not needed, and attempts to do so are error prone. +The TMC2130 and TMC5160 have both a `diag0_pin` and `diag1_pin` in most known hardware the `diag1_pin` is appropriate. In order for klipper to correctly configure the driver for sensorless homing, the correct configuration property name `diag0_pin` or `diag1_pin` must be used. Which is used is determined by which driver pin is connected to the MCU pin. + ATTENTION: This guide only mentions the mandatory parameters and the ones needed to set up sensorless homing. There are many other options to configure on a TMC2130, make sure to take a look at `config/example-extras.cfg` for all the available options. ## Testing of SPI/UART communication |
