Some TMC stepper drivers can detect when they bump into something that causes them to stop moving. This feature is so sensitive that it can actually take the place of traditional endstops. Use this command to set the bump sensitivity for the X, Y, and Z stepper drivers.
Set all *_HOME_BUMP_MM values to 0 for best results.
Set the default stall thresholds with *_STALL_SENSITIVITY.
Compatible with TMC2130 and TMC2209.

High sensitivity may produce false positives.
Low sensitivity may fail to trigger.
