The name of the virtual end stop pin is derived from the name of the TMC2130 section.
The name of the virtual end stop pin is derived from the name of the TMC2130 section. 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.
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.
