esp_set_soft_limit() defines the right and left software travel limit for the specified axis.
Software travel limits are referenced to absolute position zero(0), or home position after
homing has been performed.
Normally, after a system reset, the stage is first homed so that software travel limits are
referenced to a known, repeatable location.
Software limits help prevent inadvertent travel into stage hardware limits.
esp_get_soft_limit() reports the right and left software travel limit setting for the
specified axis.
Software travel limits are ignored during homing mode.
